AirMap Portable Power Pack

Operation Instructions

This portable power pack is designed for use with the following products: Lowrance Avionics AirMap 1000 and AirMap 2000c mapping GPS receivers. It is compatible with related Lowrance GPS units using similar connectors and 12-volt power sources. The AirMap units are designed to use multiple power sources. The external power cable with cigarette lighter adapter plugs into a 12-volt system and supplies 6 volts of DC power to the unit. The units themselves contain AA batteries, which serve as automatic emergency backup power if external power fails. This AirMap Portable Power Pack serves as the primary external power source in aircraft without cigarette lighter power sockets or as an additional backup for planes with power sockets. The portable power pack makes it easy to run the unit in your own aircraft, a rental plane or a friend's plane. (Or, you can easily take along your AirMap GPS in a boat, car or other vehicle.)

BATTERY CARE Make sure the battery is fully charged before you use the AirMap PPP for the first time. When fully discharged, it takes approximately nine hours to recharge the battery. Under ordinary operating conditions, the battery will run your unit with the backlight on full bright for approximately 10 hours and with the backlight at a reduced level, about 24 hours. (Battery capacity will vary depending on the temperature and backlight use.)
Red connector Charger Black connector
Battery Indicator light Battery charger's indicator light glows red when charging, green when battery is fully charged. To charge, attach red connector to red (positive) contact and black connector to black (negative) contact.
To charge the battery, plug the charger into a 110 VAC electrical outlet, then connect the red lead to the red battery contact and connect the black lead to the black battery contact. When you plug in the charger, the indicator light glows green to indicate it is receiving power. When you connect the battery, the light turns red, showing it is charging. When the light turns green again, the battery is fully charged. You can recharge the battery after every flight, even if the battery was not fully discharged. This will always keep the unit ready for your next trip. Disconnect the battery when stored for long periods of time. You should also consider charging the battery once a month while in storage. BATTERY CONNECTIONS TO AIRMAP 1. Attach the power leads from the power cable to the battery terminals. Connect the red wire to the (red) positive terminal and connect the black wire to the (black) negative terminal.

After mounting the AirMap, turn it on. If it won't turn on, make sure the power leads are firmly connected to the battery terminals. Also, make sure the lead colors match the battery terminal colors (red positive to positive and black negative to negative). If it still doesn't work, check the battery voltage. Most problems with portable units result from batteries that have not been charged. Keep in mind that in cold weather, battery efficiency drops with the temperature. It is a good idea to keep the battery at room temperature before leaving home.

INTRODUCTION Thank you for purchasing a Lowrance Avionics AirMap 300. With its large LCD screen, easy to use menus, and outstanding performance, we think youll be happy with your AirMap 300 for many years. No other handheld GPS receiver on the market today has the AirMaps combination of 12 channel receiver, Jeppesen database with obstacles (U.S. only), ground and hydrographic mapping cartridge capability, and programmable screens in a handheld unit. Like most GPS receivers, your AirMap 300 doesnt have a compass or any other navigation aid built into it. It relies solely on the signals from the satellites to determine its position. Speed, direction of travel, and distance are all calculated from position information. Therefore, in order for it to determine the direction youre travelling, you must be moving, and the faster - the better. This is not to say the unit wont work at walking speeds - it will. But the faster you travel, the easier it is for the unit to determine your direction. GPS works from satellites that transmit information to the world at very high frequencies. One disadvantage to this frequency is that its line-ofsight. In other words, the signals dont bounce around like your local radio or television. If you dont have a clear view of the sky, or if youre inside a metal building, the unit probably wont be able to pick up the signals from the satellites. This is common among all GPS receivers. We have found that using this product inside an aircraft is usually sufficiently close to the windows and windshield that it works well. However, the included remote antenna bracket and cable (model PA-2) lets you mount the removable antenna on top of the dash, in case its required. Another factor that influences the GPS position and navigation capabilities is called selective availability or SA. This is small errors purposefully injected into the transmitted signal from the satellites. The government does this to degrade the systems accuracy to civilian and foreign users. Even with SA, GPS is the most accurate navigation system ever invented on such a large scale. The Governments accuracy specification is 100 meters horizontally and 150 meters vertically 95% of the time. In other words, the position shown on your AirMap 300 could be up to 100 meters in any direction from your actual position, and the altitude could be plus or minus 150 meters from whats shown on the screen, 95% of the time. One way around the S/A problem is to purchase a DGPS receiver and connect it to your AirMap 300. A DGPS receiver (commonly called a beacon receiver), picks up correction signals broadcast from ground stations.

Finding Your Position

Cold Start When its turned on for the very first time, the GPS receiver doesnt know where it is, nor what the local time or date is. If you tell it your position, time, and date, the unit will take less time to lock-on to the satellites and give you a fix or position. However, if you dont want to push buttons at this time, thats fine. The AirMap 300 will lock onto the satellites and give you a position without any input from you. This is called a cold-start. It simply means that the unit is searching without your help for the satellites that are in orbit. A cold-start can take up to 5 minutes to acquire enough satellite data to determine your position, although it typically takes less time than that. Once the GPS receiver locks on to the satellites and finds your position, it stores the satellite data in its memory. The next time you use the unit, it should take less time to lock on.
Once the AirMap 300 locks on to the satellites and finds your position, it stores the satellite data in its memory. The next time you use the unit, it should take much less time to lock on. To use your AirMap 300, first take it outside, away from hangers and buildings. You need a clear view of the sky. Open the antenna and adjust it so that it is parallel with the ground. Press the PWR key. Read the message on the screen, then press the EXIT key to erase the message. A screen similar to the one at right appears. This is Map 3. Your present position is shown as a cross surrounded by a diamond. As you wait for the AirMap 300 to find your position, youll see numbers flashing on the display. Anytime you see flashing numbers, it means the AirMap 300 does not have a position! Do not rely on any data that is flashing! When the numbers stop flashing, the unit has locked on to the satellites and the position is good. Thats all you have to do to find your position. The time display may not be correct when the cold start method is used. See the manual initialization section for details on changing the time.

NORTH-UP

TRACK-UP
In the example at the bottom of the previous page, we're travelling with a track of 200. In the north-up view, the present position indicator appears to move towards the lower left corner of the screen. In the track-up view, the present position moves straight towards the top of the display. A "N" shows to help you see which direction is north when the track-up mode is on. Remember, the track-up mode, the screen rotates as you change direction. It always keeps your direction of travel (track) heading towards the top of the screen.

COURSE-UP

In the course-up mode, the screen is locked into your original bearing to the recalled waypoint, (user waypoint, airport, NDB, VOR, or cursor location) regardless of your track. (Note: the track-up and course-up modes do not work when the unit is zoomed-in on a C-Map cartridge.) To select the desired mode, press the up or down arrow keys to move the black box to the UP ORIENTATION, then press the right arrow key to select it. Press the EXIT key to return to the mapping screen.
EARTH MAP OPTIONS The earth map consists of the built-in background map of the world, plus any cartridge that is attached to the AirMap 300. To change the Earth map options, first press the MENU key, then press the up or down arrow keys until the Earth Map label appears. Highlight the label, then press the right arrow key to select it. The screen shown at right appears.
Text Labels Use this menu to turn all names on the map (such as Lake Tahoe or Mississippi River) off or on. The default is on. Press the left arrow key to turn them off. Map Boundaries If you have a IMS SmartMap or a C-MAP cartridge plugged into the back of the AirMap 300, this feature will show the boundaries of the cartridge on the map. This lets you know the exact area covered by your cartridge. The example at the top of the next page shows the boundaries of the Oklahoma - East IMS SmartMap cartridge. The default for this feature is on. Press the left arrow key on the MAP BOUNDS label to turn them off.
Move Map Center In normal operation, the present position indicator stays in the center of the screen and the map moves past it as you travel. To move the present position indicator to a different part of the screen, highlight the Move Map Center label on the Earth Map Options menu and press the right arrow key. The unit returns to the mapping screen with the message Set Map Center flashing at the bottom of the screen. Use the arrow keys to move the present position indicator to the desired location on the screen, then press the EXIT key. This locks the present position indicator in this location.
The above examples show the present position in the center of the screen, then moving the present position down and to the left. This shows more of the lake.
Earth Map On/Off You can turn the earth map completely off, clearing the screen of all ground detail (including IMS SmartMap cartridge detail). To do this, highlight the EARTH MAP OFF/ON label and press the left arrow key. Icons On/Off The AirMap 300 has symbols that you can place at any location. These symbols can be turned off, if desired. To do so, move the black box to the ICONS OFF/ ON label and press the left arrow key. See the ICONS section in this manual for more information on the icon symbols. Note: This doesnt erase the icons, it merely hides them. Detail Cartridge The AirMap 300 has two cartridge slots in its back. Either one can hold a IMS SmartMap or C-MAP cartridge. The unit can only show detail from one type of cartridge at a time. In other words, you cant show detail from an IMS SmartMap and a C-MAP cartridge at the same time. You must select one or the other. The Detail Cartridge menu lets you select the type of cartridge to display. When you install a mapping cartridge, and wish to use it, switch the Detail Cartridge to the desired selection on this menu. To do this, simply highlight the menu, then press the left or right arrow keys to select the proper cartridge type. C-MAP OPTIONS If you are using this receiver with a C-Map cartridge, a new menu appears on the main menu list. This is the C-Map Options menu. Highlight this menu item and press the right arrow key. The screen at right appears. These menu items let you turn the depth lines, restriction areas, coastal features, and marine navigation aids off or on. Highlight the desired feature, then press the right or left arrow key to change them. Press the EXIT key when youre finished.

Clock Set If the time shown on the clock display is not your local time, change it using the Clock Set function. To do this, press the MENU key, then press the up or down arrow keys until the Clock Set label is highlighted. Press the right arrow key. The screen at right appears. Using the right and left arrow keys, highlight the first number in the time that you want to change. Now press the up or down arrow keys until the desired number shows. Continue until the time shown in the display is correct, then press the ENT key. The unit returns to the navigation, mapping, or windows display with the new time showing. Clock Hours Normally, the time shows in the twelve hour format (a.m./P.M.). To change it to 24-hour format, press the MENU key, then select the CLK HRS label. Now press the right arrow key to change it to 24, then press the EXIT key. Clock Alarm You can set an alarm (that works just like an alarm clock), by using the Clock Alarm menu. To set this alarm, press the MENU key, then highlight the Clk Alm Set label. Press the right arrow key. A screen similar to the one at right appears. Using the right and left arrow keys, move the black box to the first number in the time that you want to set. Now press the up or down arrow keys until the desired number shows. Continue until the time shown in the display is correct, then press the ENT key. The unit returns to the navigation, mapping, or windows display. To turn the alarm on, press the MENU key, then select the CLK ALM menu. Press the right arrow key. The alarm is now activated. When the alarm goes off, an audible tone sounds along with a flashing message on the screen. Press the EXIT key to turn the alarm off. Note: The AirMap 300 must be on in order for the alarms to work. In other
words, if you set the alarm to go off at 7:00 a.m., then the AirMap 300 will have to be on at 7:00 a.m., also. TIMERS The AirMap 300 has two timers built in. One is a countdown timer and the other is a count-up timer. The countdown timer counts down from the time you put in to zero. The count-up timer starts at zero and counts up to the time you entered. To set either timer, first switch to a screen that is showing the timer that you want to use. Next, press the MENU key, then highlight the desired timer set menu. In this example, were setting the countdown timer. Now press the right arrow key. A screen similar to the one below appears. Using the right and left arrow keys, move the black box to the first number in the time that you want to set. (The time is in hours, minutes, and seconds) Now press the up or down arrow keys until the desired number shows. Continue until the time shown in the display is correct, then press the ENT key. In this example, the down timer is set for 10 minutes. The unit returns to the navigation, mapping, or windows display. To start the timer, press the MENU key, then move the black box to the Dn Timer STOP/ GO label. Press the right arrow key to start the timer. The timer continues counting until you stop it. If you turn the up timers alarm on (press the right arrow key when the black box is on the (Up ALM.Off/On label), it will sound a tone when it reaches the time you entered in the up timer set menu. Press the EXIT key to silence the alarm. You can reset either alarm to the time you originally set by pressing the MENU key, then moving the black box to either the Up Timer Reset or DN Timer Reset label, then press the right arrow key.

AIRPORT

INTERSECTION 45
To find a particular airport, VOR, NDB, or intersection, first switch to the appropriate database. In this example, well use the airport database. Suppose were planning a trip to Fort Smith Regional airport in Fort Smith, Arkansas. There are three ways to find this airport in the AirMaps database. You can find it by searching through the airport identifiers (ID), airport name, or city. In this example, we know the airport identifier is FSM, so well move the black box to the ID label by pressing the down arrow key once.
Select the first letter in the identifier by pressing the up or down arrow keys until the letter F appears in the ID field. When it does, press the right arrow key once. This moves the selector to the second number in the identifier field. Again, press the up or down arrow keys until the letter S appears.
Finally, press the right arrow key one more time, moving the selector to the last number in the ID field, then press up or down arrow keys until the letter M appears. The screen should look like the one at right. You can find an airport by using the airport name (name) or city fields the same as the ID field. Simply move the black box to the desired label, then use the arrow keys to select the name. After youve found the airport, press the EXIT key. The screen shown at right appears. At the bottom of the screen is the airports elevation, which in this case is 469 feet. Beneath this is the airports position, and at the very bottom of this screen in the distance and bearing from your present position to the airport.
Communication Frequencies To view the communication frequencies used at the selected airport, press the down arrow key, move the black box to the COMM FREQUENCIES label and press the right arrow key. The screen shown below appears.
This is the communication frequencies screen. In this example, all applicable com frequencies for Fort Smith Regional airport are shown. Also, this airport has more frequencies that can be shown on one page. Press the left or right arrow keys to view the rest of the radio information. When youre finished with this screen, press the EXIT key. The AirMap 300 returns to the previous database screen. Runways To view the runway information, press the down arrow key on the airport database screen shown at the top of this page until the black box is on the RUNWAYS label, then press the right arrow key. A screen similar to the one at right appears. The runways label is highlighted. Press the right arrow key to select it. The screen shown below appears. The active runways available at the time of your database are shown on the left side of the screen. Data for each runway is shown on the right side of the screen. In the example screen shown above, runway 7 - 25 has a hard surface, is 8000 feet long and 150 feet wide. It also has lights which are activated on 118.30 mHz. To view the data for the other runway, press either the right or left arrow key. The screen shown at the top of the next page appears. Now information for runway 1 - 19 is shown on the right side of the screen.

If the airport has more than two runways, simply keep pressing the right or left arrow keys until the desired runway appears. When youre finished with this screen, press the EXIT key to return to the airport database screen. Runway Extensions This unit can draw an extension onto a runway to make it easier to line up to the runway on final approach. To use the extension, you must first navigate to an airport. (See the Navigation section for more details.) In this example, were navigating to Halliburton field in Duncan, Oklahoma. Next, select Runways/Extensions from the Airports database as shown at right. The screen shown below appears. Now highlight Runway Extensions on this menu and press the right arrow key.
Use the left or right arrow keys to select the desired runway. In this example, were using runway 17. Press the ENT key when the desired runway appears.
A line is drawn on the screen extending from the airport in line with the selected runway. To turn the extension off, repeat the above steps, but press the EXIT key on the above menu.
Services To view the services available at the airport, press the down arrow key on the AIRPORTS main menu shown at the top of the previous page until the black box is on the SERVICES label, then press the right arrow key. The screen at right shows. After viewing the information, press the EXIT key to return to the airport database screen. Other Aviation Databases To view VOR, NDB, or intersection data, simply switch to the desired database, then use the arrow keys to view it. They work identically to the airport database. Note: The VOR database as shown at right has a space to the right of the frequency box. If the VOR has DME, the letters DME appear in this box. If not, the box is left blank.
USER DATABASE The AirMap 300 gives you the capability of creating your own database of locations, called waypoints. These locations are stored in the User WPTs section of the database. You can save your present position, cursor position, or enter a latitude/longitude and save it as a waypoint. Saving Your Present Position as a Waypoint (Quick Save Method) To save your present position, simply press the WPT key twice. The AirMap 300 puts your current position into the first available waypoint number on the list. A message appears on the display telling you the waypoint number it just used. This also momentarily places you in the database menu as shown at right. Anytime a database menu is showing, simply press the WPT key once and the unit will store your present position in the waypoint list.

WAYPOINT NAMES The AirMap 300 lets you assign a name to each waypoint. The name can have up to twelve characters. To name a waypoint, first select the waypoint number that you wish to name. (Note: A waypoint must have a position stored before you can name it.) Now highlight the EDIT NAME label
and press the right arrow key. A screen similar to the one at right appears. Press the up or down arrow keys to select the first letter in the name. Press the right arrow key to move the black box to the next position in the name. Repeat this sequence until youve entered all of the letters in the waypoint name. Press the ENT key to accept this name, the WPT key to erase all characters in the name, or the EXIT key to leave this screen without saving any changes. Tip: You can select waypoints by name instead of by number. Simply press the right arrow key while the black box is on the Name portion of the waypoint menu, then press the up or down arrow keys until the desired waypoint name appears. WAYPOINT ICONS When you save a waypoint, an icon is automatically assigned to it. If you wish to change the icon, first press the waypoint key, select the waypoint you want to change, then highlight the EDIT ICON label. Now press the right arrow key. The screen shown at right appears. Press the arrow keys to highlight the desired icon, then press the ENT key to assign it to your waypoint. The unit returns to the waypoint screen with the icon you selected assigned to the waypoint. Delete a Waypoint To remove all information from a waypoint location, first select the waypoint number on the waypoint menus first page that you wish to delete. Next, highlight the Other Options label. Press the right arrow key. Now highlight the Delete A Waypoint label. Press the right arrow key. A message appears, asking you if you really want to delete the selected waypoint. If you choose yes, all information in the selected waypoint will be deleted. The unit returns to the second waypoint menu page. You can make other waypoint selections or press the EXIT key to erase this menu.
Move a Waypoint You can move all information from one waypoint number to another. In this example, well move all of the information in waypoint number one to waypoint number 10. To do this, go to the second waypoint menu page. Now highlight the Move A Waypoint label. Press the right arrow key. The screen shown at right appears. The Select From label is highlighted. Using the down arrow key, highlight either the name or waypoint number labels. You can select a waypoint to be moved by name or number. In this example, its already on waypoint number one. Once you have the desired waypoint showing on the screen that youre going to be moving the information FROM, then you need to choose the waypoint number that youre going to move that information TO. Highlight the Select label at the top of the screen, then press the right arrow key to select TO. Now choose the waypoint number that you wish to move the information to. In this example, we selected waypoint number 10. When everything on this screen is correct, press the WPT key. In this example, the name, icon, and position were moved from waypoint number 1 to waypoint number 10. Press the EXIT key to erase this screen when youre finished.

last known track direction. When you resume speed, all features operate normally. When youre stopped, the track holding feature is useful to prevent the annoying random numbers from appearing on the display while you're stopped. This also prevents the unit from rotating the map in all directions when it's in the "track-up" mode. This feature is useful when you're using the AirMap 300 while taxiing, or other typically slow-speed activities. To turn the track holding feature off, press the MENU key, then press the up or down arrow keys until the System Setup menu appears, then press the right arrow key. The screen shown at right appears. The track holding menu is at the top of this screen. Press the left arrow key to turn the track holding feature off. Press the EXIT key to erase this menu.
GPS CORRECTIONS DATUM Maps and charts are based on a survey of the area thats covered by the map or chart. These surveys are called Datums. Maps that are created using different datums will show the same latitude/longitude in slightly different locations. All datums are named. The GPS system is based on the WGS-84 datum, which covers the entire world. Other datums may also cover the entire world, or just a small portion. By default, the AirMap 300 shows your position on the map using the WGS-84 datum. However, it can show your position using one of 99 different datums. To change the datum, first highlight the GPS Corrections label on the System Setup menu and press the right arrow key. Now highlight the Select Datum label. Press the right arrow key. A screen similar to the one at right appears. The WGS-84 label is highlighted. To change it, simply press the up or down arrow keys until the desired datum is highlighted, then press the ENT key. This selects the datum and erases the datum menu. The AirMap 300 is now using the datum you selected.
PCF (Position Correction Factor) Another method used to make your display match a chart or map is called PCF or Position Correction Factor. This unit gives you the capability to move or offset the position shown on the display to match one on the chart. The unit will add this offset to all position and navigation displays at all times. Remember, the position error on any radio navigation system is very dynamic and the PCF offset should never be used in an attempt to cancel the error. In general terms, PCF should only be used if your map indicates what the possible error is. PCF should always be reset to zero when youre finished with the chart. For example, suppose you are stopped at a location that is accurately marked on a chart. Your unit shows a longitude position that is.244 minutes east of the one on the chart and.047 minutes north latitude. Using the PCF feature, you can make the AirMap 300 match the chart youre using. If you move, the unit will continuously add the change to all position, navigation, and mapping displays. This makes it more closely match the datum used by the chart. For this reason, you should be careful when entering the PCF offset. Its saved in memory and doesnt change when the unit is turned off. However, resetting the unit does erase the PCF offset. To set the PCF offset, highlight the Set Position Correction Factor label on the GPS CORRECTIONS menu and press the right arrow key. The screen shown at right appears. Now enter the correction for your location. Remember, this is the difference between the location shown on the present position display and the position shown on the chart. In this example, we entered 0 degrees, 0.047 minutes north latitude and 0 degrees, 0.244 minutes east longitude. That is the difference between the present position shown by the AirMap 300 and the one on our chart. After youve entered the latitude/longitude correction, press the ENT key to accept it. The AirMap 300 returns to the navigation or mapping screens with the correction factor applied.

SIMULATOR A simulator is built into the AirMap 300 that has several options. You can use nearly all of the units features - even save and recall waypoints. This is useful for flight planning. You can fly the route at any speed before ever stepping foot in an airplane. To use the simulator, press the MENU key, then press the up or down arrow keys until the Simulator Setup menu is surrounded by the black box. Now press the right arrow key. The screen shown at right appears. If you simply press the right arrow key, turning the simulator on, the AirMap 300 will start from your present position and fly a track of 355 at 100 knots. To change either the track or speed, move the black box to the one you want to change, then press the right arrow key. Use the up and down arrow keys to change each number, then use the left and right arrow keys to select the other numbers that you wish to change. On the example at right, the track is being changed from 355 to 120. When the num

bers are correct, press the EXIT key. Starting Position Normally, the starting position for the simulator is your present position. If you want to change the starting position, move the black box to the SET START label, then press the right arrow key. The screen shown at right appears. You can select any user waypoint, airport, VOR, NDB, or intersection as the simulators starting point. Select the starting point, (See the database section for information on using the database selection) then move the black box to the SET AS SIM START label and press the right arrow key. The AirMap 300 returns to the Simulator Setup menu. Use Arrow Keys to Fly This option lets you change both the course and speed on the screen as the simulator is running. To do this, move the black box on the Simulator Setup screen to the User Arrow Keys to Fly label, then press the right arrow key. The screen shown at right appears. Use the up and down arrow keys to increase or decrease the airspeed. Use the right and left arrow keys to change the track. If you hold the left or right arrow keys down, the track changes at 6 per second. You can change this to 3 per second by moving the black box to the Turn Rate label on the simulator setup screen, then pressing the left arrow key.

E6B COMPUTER To help you with flight planning, the AirMap 300 has a computer built into it that lets you calculate density altitude, true airspeed, wind speed and direction, plus vertical navigation. To use this computer, first press the MENU key, then highlight the E6B Computer label. The screen shown at right appears. Highlight the desired mode and press the right arrow key.
Density Altitude/True Airspeed To calculate density altitude or true airspeed, simply highlight each item on the list at right. Youll need the indicated altitude I ALT, barometric pressure (BARO) in inches of mercury, outside air temperature (TEMP), and calibrated airspeed (CAS).
On the example shown at right, the indicated altitude is 5500 feet, barometric pressure is 30.02, outside air temperature is 67 Fahrenheit, and the calibrated airspeed is 129 knots. This gives us a pressure altitude of 5407 feet, a density altitude of 7141 feet, and a true airspeed of 143.6 knots. Obviously, you dont need an airspeed to calculate density altitude, this was done for illustration purposes.
Wind Speed/Direction To determine the wind speed and direction, first solve for true airspeed on the previous screen. Then, highlight Wind Spd/Dir on the E6B Computer menu. A screen similar to the one at right appears. With true airspeed solved, the only other thing necessary for the unit to determine the wind is your course over ground (CRS). In this example,
