DroidEFB Key

DroidEFB Key – Feature Description:
This detailed listing contains a description of the 33 items depicted on the “DroidEFB Key”, page 8. The key is shown with “Split Screen” enabled in Preferences. The top half of the key displays the “chart view” while the lower half displays the “details view”. Some items are suppressed without a GPS signal or data connection (Item 20).

Navigation Drawer – This is a flexible menu that displays:
• Charts
• Tools
• Recent
The last 8 documents are selectable by default.
Charts and plates are viewable via our server with an Internet connection but must be downloaded for offline use.

Nearest Airports – Touch this icon to see a query view list of “nearest” airports (GPS required). Touch any found airport to display the Details View (Item 24) for that airport. Without a GPS fix, the “Find” and “Direct To” (Items 17-18) buttons are suppressed. List is continuously update in flight.

Center On Current Position – Touch this icon to automatically center and scroll on the current position (Item 30).  This icon only appears when location is set by GPS and the chart center is moved from the current position (Item 20 and 30). 

  1. POI search – Internet access is required when searching for points of interest other than NAVAIDs, waypoints and airports.  This search uses predictive lookup as characters are typed allowing an item to be selected at any time.  Touching an item will cause it to display the Info Box (Item 12).  Touch the Back Button (Item 23) to close it.

Long press the info box for a list of additional tasks such as:

  • Go Direct To POI
  • Insert POI into flightplan
  • Append POI to flightplan
  • Create User Waypoint (Item 11)

The database uses ICAO abbreviations, so remember to use the “K” prefix, as required. 

Split Screen Control – This icon appears only if split-screen mode has been enabled in Preferences.  The arrows point up-down or left-right relative to screen orientation.  When split-screen mode is disabled, only one arrow is present.  With split screen enabled, the arrows allow minimizing and maximizing of the details view (Item 24).  Split screen settings are accessed via the Main Menu (Item 6) > Preferences > General > Split Screen.

Main Menu

This icon is the entry to updating airport data and charts, setting preferences, help and exiting the program.  This may be a virtual key or traditional hardware key on some devices.  If no Internet connection is available, the data items will be ghosted and inactive.  Notice, the same icon appears at the top of the Flight Plan tab when open (Item 8) and allows actions relative to the current flight plan: Clear, Invert, Save, Load, Delete and Quit.

Chart View – Right side:

Items 7-19 discuss the details pointed out on the right side of the DroidEFB key.

NEXRAD/TFR Age/Notification Area –The top center of the chart is used to display time since TFR and NEXRAD data were last downloaded as well as other notifications depending on 3rd party device being used.  A data connection is required to receive updated TFR and NEXRAD information.  Refer to Quick Setting/Notifications (Item 20) for additional device and application notifications.

Flight Plan Tab

Touch the Flight Plan tab to open or close it and view or edit waypoints.  Long press the tab to automatically display all planned waypoints on the selected chart.  Touch the “+” symbol to insert an airport, NAVAID, coordinate, victor airway, or intersection. Acceptable coordinate entry formats are as follows (use “:” or “.” to differentiate coordinate type, no spaces):

NOTE: Precise coordinates are used, the only rounding is in the displayed name.

  • Degrees.Decimal minutes (DDD): 34.639333,-86.7815
  • Degrees:Minutes:Seconds (DMS): 34:38:21,-86:46:53
  • Degrees.Minutes.Decimal (DMM): 34.38.360,-86.46.890

Multiple waypoints can be loaded at a time by using spaces between the identifier and name i.e., KHSV RQZ V321 SYI KSYI.  Radial and distance format is FIX/RADIAL/DISTANCE.  Enter planned TAS for a flight while not airborne to calculate estimated time enroute.

Touch an airport, NAVAID, waypoint or coordinate in the flight plan to center it on the chart and view its info box (Item 12).  Long press an airport, NAVAID, waypoint or coordinate for additional options, such as choosing entry and exit points along a victor airway. 

The “Flight Plan Main Menu”, displayed with the Flight Plan tab open, displays the usual actions relative to the current flight plan: Clear, Invert, Save, Load, Delete.  Flight Plan information is automatically transferred to the Flight Pad (Item 1) and Flight Pad Briefing tab for viewing, editing and filing directly with Lockeed Martin Flight Services.  If the route is edited via Flight Pad, you will be given the option to transfer the updated route information to the Flight Plan tab.  The Flight Plan tab will highlight YELLOW when NOTAMs are available via ADS-B or if METAR information has been updated but not yet viewed.

Layers Tab – Touch the Layers tab to open or close it.  Long press to hide all layers for 5 minutes.  While open, options for NEXRAD, Winds, SIG/AIRMETS, METARs, PIREPS, Track Log/Crumbs 

(Visit www.droidefb.com for a Track Log Tutorial), Show Magnetic Rose, Display TFRs and XRX Traffic are available.  Tab layout varies by type of third party device being used.  If an Internet or data connection is not available, deselect data items to prevent connection notifications from appearing while in flight. 

Long press a layer displayed on the chart, such as AIR/SIGMET or TFR for an option to display more information.

Sensors Tab – Touch the Sensors tab to open or close it.  From here, the magnetic heading (Item 32) can be calibrated, the GPS source being used for position calculations can be changed and altimeter setting can be set (for devices with built-in altimeter).  Configure DroidEFB to use built-in altimeter and paired Bluetooth or Wi-Fi devices via the “Main Menu (Item 6) > Preferences > Device Settings.”  DroidEFB looks for built-in and external devices only during initial startup.  Bluetooth devices must be turned on and paired prior to starting DroidEFB.  (Helper apps or mock locations not required)

The built-in altimeter, if enabled, automatically adjusts every 10 minutes when below 30KIAS.  Override the adjustment by changing the altimeter.  If overridden, the altimeter will start updating itself again after one hour.  To start auto adjusting sooner, select “Reset”.  The altimeter will display 29.92 initially and altitude will display in red. 

With a valid weather source available less than 60 minutes old, the altimeter will auto adjust within 15 seconds.  When altimeter data is between 60 and 75 minutes old, the altitude will display in yellow.  When the altimeter is more than 75 minutes old, altitude will display in red.  While airborne, the altimeter may be adjusted from one station to another, as the flight progresses or advised by ATC.  The current altimeter setting does not account for atmospheric irregularities such as being inside a pressurized aircraft, moving to areas of higher or lower pressure, effects of temperature or device calibration errors.  Virtual rotation vector sensor is the recommended setting when displaying magnetic heading.  If use rotation vector is not selected then physical accelerometer + physical magnetic field sensor is being used.  To determine the setting that is best, make sure the magnetic heading triangle (Item 32) is red.  Rotate the device and observe that the indication moves freely and is proportionate to change (i.e. 90 degrees).  If not, deselect “use rotation vector sensor” and try again.

User Waypoint

User waypoints can be created then saved, edited and synced across user devices.  Create a user waypoint by long pressing a location on the chart, an info box (Item 12) generated from the POI Search (Item 4) or GPS WPT.  Acceptable coordinate entry formats are as follows (use “:” or “.” to differentiate coordinate type, no spaces):

NOTE: Precise coordinates are used, the only rounding is in the displayed name.

  • Degrees.Decimal minutes (DDD): 34.639333,-86.7815
  • Degrees:Minutes:Seconds (DMS): 34:38:21,-86:46:53
  • Degrees.Minutes.Decimal (DMM): 34.38.360,-86.46.890

Touch the “Main Menu (Item 6) > Preferences > User Waypoints” to view and edit a waypoint.  Waypoints are synced each time DroidEFB is launched with an Internet connection present and the user logged in.

Info Box – Touch an airport to display the info box.  Touch the Info Box to expand the Details View (Item 24) or press the Back Button to close it. Touch “ID” to for Morse Code.

On IFR, low and high altitude enroute charts, touch NAVAIDs and intersections to view the Info Box, also.  The info box shows bearing and distance in the upper right corner (GPS required), airport elevation, coordinates and ICAO identifier.  With NAVAIDs, the frequency is listed.  With intersections, REP-PT is listed.  For airports, additional information includes the airport name, its town, the size and direction of the longest runway, the CTAF or tower frequency and the current METAR (Data connection required).  

Info Box Action Bar –

Direct-To – This icon is suppressed if GPS position (Items 20 and 30) is not known.  This icon displays by touching a location on the chart, a flight plan waypoint (Item 8) or if a POI (Item 4) has been selected.  Touching the Direct-To adds, inserts or appends the new waypoint into the flight plan tab (Item 8).

Runway Highlight – Touch this icon to select and highlight the intended runway for approach or departure or “Find” the runway.  Arrows along the extended runway centerline indicate traffic pattern direction.  If airspeed is less than 30 knots, the indication displays the appropriate takeoff direction.  If greater than 30 knots, the appropriate landing direction is depicted.  

Weather – Touch this icon or the weather tab (Item 16) to retrieve and display a complete weather summary in the Details View (Item 24).  Touch the toggle icon to change time display.

Choose imagery to display via “Main Menu (Item 6) > Preferences > Imagery.”  This icon is suppressed if a data connection is not available.  Available weather comprises unexpanded text of local METAR history, TAF (if available), Local Radar and Radar Tops.

Tap on the Google search bar from the Home Screen then choose “Menu > Settings” to configure your device to search the DroidEFB database from the Google search bar.  Results may vary by device.

Obstacle data:

Obstacles taller than 200’ AGL are displayed on the chart with speeds above 30 Knots.  Red indicates obstacle within 200 feet of current position, yellow indicates obstacles within 1000 feet and gray indicates obstacles more than 1000 feet to 3000 feet below current position.

Special Use Airspace – Legend Information:

Long press within the depicted boundaries of a Restricted (R) Area, Prohibited (P) Area, Military Operations Area (MOA), Alert Area (A), Warning Area (W) or National Security Area for an option to display its details.  Revisions to this information are published annually and no updates are published between editions.  Flight Service maintains the most up to date information regarding SUA.


The SIG/AIRMET “Layers” dropdown allows plotting of particular hazards such as icing, convection, turbulence, IFR, mountain obscuration and volcanic ash.  All items may be shown at once or selected individually to reduce clutter and improve device performance.  Like TFRs, long press a displayed icon or region to view raw AIRMET or SIGMET data.


A SIGMET (Significant Meteorology Information) advises of weather potentially hazardous to all aircraft other than convective activity.  SIGMETs are issued for:

  1. Icing –
  2. Turbulence –
  3. Convection –
  4. Volcanic Ash –


An AIRMET (Airman’s Meteorological Information) advises of weather potentially hazardous to all aircraft but that does not meet SIGMET criteria.  AIRMETs are issued for:

  1. Icing –
  2. Turbulence –
  3. Mountain Obscuration –
  4. IFR –

Updating Charts and Airport Databases: 

The first time you use DroidEFB, it will be necessary to select the chart types, states and territories you wish to download data for.  “Update Airports DB” must be selected prior to “Update Charts”.  This updates a textual database for the entire country, regardless of states or territories selected.  “Update Charts” checks the Airports DB for imagery, charts and procedures needing downloaded based on States/Territories and Chart Types selected under Preferences.  Each time DroidEFB is launched, a “Data Expires” dialog appears momentarily indicating when either Charts or DBs are no longer current.

Cool Extra Stuff: 

The following pages contain instructions for connecting and interacting with optional third party devices.  As DroidEFB. implements and tests these devices, the manual will be updated to reflect advances of functionality.  Helper apps are not needed nor should “Allow mock locations” be selected on ALL Android devices.

Zaon XRX Traffic Awareness Integration:

DroidEFB  and the Zaon XRX Portable Collision Avoidance System (PCAS) integrate to provide high-quality, low cost traffic information.  Direction, range and relative altitude of threats are displayed on the chart, in relation to the aircrafts current position.  

  1. Obtain a PCAS XRX and connect it to the XRX BlueLink Bluetooth module available from www.zaon.aero.
  2. See “Placement Considerations” and “Compass Calibration” in your XRX Owner’s Manual.
  3. Use the “Com” menu on the PCAS XRX to choose “Profile 1” or “Anywhere Map” as the output method.
  4. Use the “Alt” and “Range” menus on the PCAS XRX to set detection range to 6NM and ±2500 feet.
  5. Touch the Layers tab > XRX Traffic on DroidEFB (GPS required).

Baron WxWorks Integration:

  1. Obtain WxWork data receiver, Baron Mobile Link device and Wi-Fi antenna from www.baronservices.com/mobilelink
  2. Obtain a XM WX Satellite Weather subscription.
  3. Configure SSID by touching the “Menu > Preferences > Device Settings > Baron MobileLink SSID.”  The SSID must match the one the MobileLink device uses, which is “MobileLink” by default.
  4. Establish a Wi-Fi connection with your Android device and Baron Mobile Link.
