InFlight in detail

All functionality of Flight Instruments, plus more

InFlight builds on the capabilities of Flight Instruments, and adds terrain/obstacle warnings and a moving map:
  • Gyro attitude indicator, with continuous auto-calibration for optimal performance in changing environments
  • Altitude, speed, heading, vertical speed, rate of turn and slip indicators on a 'glass cockpit' display
  • Landscape mode and choice of aviation or metric display units (Android only)
  • Nearby airport information, including communication frequency, for convenient position reporting
  • Moving map display, showing terrain, obstacles and airports, color-coded to indicate hazardous situations
  • Multi-leg flight planning using aviation database for airports, VORs and NDBs
InFlight safety and redundancy by alerting you to nearby terrain and obstacles, and giving you a moving map with airports that are color-coded to indicate those within gliding range.

Terrain elevation and obstacle display and warnings

InFlight has a built-in database with terrain elevation and obstacle data.  During flight, this database is monitored to detect terrain or obstacles within 1000ft vertically of the airplane, within a 10 mile radius of your position.  If a threat is detected, it is shown as a small pop-up map on the primary flight display. Yellow indicates the terrain/obstacle is between 500 and 1000 feet, red indicates the terrain is less than 500 ft below your altitude, or above you.  The popup map only shows when moving at flight speed, so as to avoid warnings on the ground.

Moving map display

The full moving map displays shows your aircraft and its surroundings.  You can pan by dragging, zoom in or out by pressing the '+' or '-' key, and center back on your plane by pressing the bulls-eye that appears when panning.  The arrow in the top left toggles between track up and North up modes.

The map shows the following:
  • Shaded terrain elevation - the color of the underlying terrain changes based on its height above MSL.  This allows you to see ridges, mountains and valleys

  • Terrain warnings - if within 1000 feet of terrain, the elevation shading is replaced with red or yellow shading to warn you to stay away from that area
  • Obstacle warnings - if within 1000 feet of an obstacle, the obstacle will show as a red or yellow 'X' mark, to indicate its location.  At this moment, obstacle data is only available for the US.  Note that obstacles are are only show when the map is zoomed in sufficiently, to avoid cluttering the display.
  • Airports - public use airports are shown as a circle, private use airports are shown as small squares (outside of the US, there is no distinction between private and public use airports, so all airports are shown as circles).  The airports are color coded as red (outside of no-wind glide range), orange (possibly within no-wind glide range), or green (likely within no-wind glide-range).  This allows you to easily see where to go in case of an emergency.  Please note that the glide ranges are based on a 1:7 glide ratio (i.e. the plane glides 7 feet for every foot of altitude loss), and is only indicative of typical general aviation plane glide ratios. Always use your own judgment and take into account all factors in deciding on a safe place to land
  • Course line - if navigation is selected, a course line is drawn from the point where the navigation was initiated, to the destination
  • Flight planning - create a flight plan graphically by adding selected navigation points (airports, VORs or NBDs) to your flight plan, and edit these by dragging the waypoints to change their order in the list
Double tapping on an airport (long-press on Android) brings up its name and identifier, and the option to navigate Direct To or add to Flight Plan.  If a flight plan is active, the magenta course line will be shown to indicate the current leg (white for other legs), and the heading indicator (on the Flight Instruments tab) will show a magenta line for Track To (i.e., the course of the magenta line), and a cyan line for Bearing To (i.e. the current direct course to the destination).

Nearby Airports

This tab will show a list of airports nearby, with similar color coding as used on the moving map to indicate airports that are likely within no-wind gliding range (black), possibly within no-wind gliding range (orange) and unlikely to be within no-wind gliding range (red).  If available, the airport information will indicate facility name, identifier, communication frequency, and length of longest available runway.   In the US, '(Pvt)' indicates the field is for private use.


The settings tabs allows configuration of the primary flight display (just like in Flight Instruments), and shows an automatic flight timer that starts when the speed reaches 50kt, and stops when it drops below that value.  On this screen you will also find the Database button, that gives information about the currently loaded regional database, and allows you to purchase a new one.

Regional databases

For terrain, obstacle and aviation data, a regional database must be purchased.  Databases are available for North America, Europe, Asia, Oceania (Australia and New Zealand) and South America.  Databases are valid until the first day of the quarter, and are available 10 days before the end of the previous quarter.  Databases can be used up to 30 days beyond their expiry date - after that, the functionality that depends on a current database will no longer be available.
Databases are purchases within the application, by tapping the 'Database' button on the 'Settings' tab.  

Please note that the database file is very large, so please download when connected to a WiFi network, and even then allow several minutes for the download to complete.  

You can switch to a different region by downloading a new database.  When switching back you will not be charged again for the original region, provided you do so before the new database for that region is available.

The databases are priced at $2.99 (or close to the equivalent in non-US markets), and are good for 3 months.  Databases expire on January 1, April 1, July 1 and October 1.
