    • Vfe is the maximum flaps extended speed or top of the white arc.
    • Vs1 is the stall speed in clean configuration or bottom of the green arc.
    • Vs0 is the stall speed in landing configuration or bottom of the white arc.


The following items are used only when an Engine Pod (Epod) is added to Apic

  • # Engines – Select the number of engines on the aircraft
  • Cylinders per engine – Select the number of cylinders per engine
  • Constant Speed Prop(s) – Set this check box to enable the Manifold pressure gauge on the RPM instrument display.
  • Fuel Tank Capacity – Set the appropriate check boxes corresponding to the fuel tanks on the aircraft and the capacity of each fuel tank in gallons.


Limits tab



Limits – Select the Limits tab to set additional aircraft parameter limits.  These are only used if an Engine Pod (Epod) is installed.  The parameter limits set here are used to define the allowable ranges drawn on the Eng.Temp and Eng.Params instruments.


All of the parameters displayed on the Eng.Params instrument are normalized and laid out as horizontal bars so that the pilot can quickly scan multiple parameters in a single glance.


  • MAP – Manifold pressure limits in inches of mercury.
  • RPM – Engine speed limits in revolutions per minute.
  • Fuel P – Fuel pressure limits in psi.
  • Fuel Flw – Fuel flow limits in gallons per hour.
  • Oil P – Oil pressure limits in psi.
  • Oil T – Oil temperature in degrees Fahrenheit.
  • EGT – Exhaust Gas Temperature in degrees Fahrenheit.
  • CHT - Cylinder Head Temperature in degrees Fahrenheit.
  • Volts – Aircraft system volt limits.
  • Amps – Aircraft system current limits.


Connections tab




Select the “Connections” tab to define how APIC connects to the various measurement devices.   APIC can connect to multiple devices either through a serial (RS232) connection or an Ethernet network.  This page allows the user to define how a device is connected to APIC and to reset the connection with a device if there is a failure.



APIC will automatically scan for a CF Card GPS during start-up if no connection has been previously defined.  If a CF Card GPS is found, APIC will set the connection to the communications port found and set the speed to 4800 baud.  APIC can run with any serial GPS that outputs standard NMEA sentences.



If an Attitude Heading Reference System (AHRS) is installed, APIC will use it as the primary source of heading, pitch and roll data.  Otherwise it will use GPS data to determine attitude. 


The Honeywell devices (HMR3000 & HMR3300) are low cost tilt compensated digital compasses and do not output valid roll data during dynamic flight conditions.  As a result APIC will only use the heading and pitch data from these devices.  Roll is computed from GPS data.


Engine Pod

Up to 2 Engine Pods (Epod) can be installed.  One per engine.


Environmental Pod

Currently the Environmental or (Vpod) is not selectable.

APIC Instruments


Primary Flight Display (PFD)



The Primary Flight Display couples many of the standard flight instruments into a single convenient display.  Information displayed on this instrument includes:

  • Attitude – An artificial horizon is used to depict pitch and roll of the aircraft.  If attitude is derived from the GPS input then pitch represents flight-path-angle and bank calculations assume that the aircraft is in a coordinated turn.
  • Heading – The compass tape at the top of the view displays either true or magnetic heading.  Tapping on the heading box will toggle between true and magnetic heading.  The letters “tru” or “mag” will be displayed to the right of the heading display box to indicate true or magnetic heading.  Magnetic variation is taken from the GPS if available.  If magnetic variation is not available from the GPS then the magnetic variation of the nearest airport is used.  If heading is derived from the GPS then it represents ground track not aircraft heading and “Crs” will be displayed to the left of the heading display box.
  • Airspeed – The speed tape on the left of the view displays Indicated Airspeed (IAS), True Airspeed (TAS) or Ground Speed (GS).  Tapping the box below the airspeed tape will toggle the type of speed displayed.  If a GPS is the only speed-measuring device connected to Apic then the PFD will only display ground speed.
  • Altitude – The altitude tape on the right of the view displays pressure corrected altitude.  Altitude may be adjusted for barometric pressure changes by tapping the virtual Kollman window box beneath the altitude tape and entering a new pressure value.
  • Battery Life - The amount of battery life in your Laptop/ Tablet device is displayed under the satellite icon.  It will show a plug with  an electricity symbol if the device is plugged in, and a battery with the remaining percentage of power off to the right if the device isn’t plugged in.


Quick Tip:  Tap or click on the altitude display box while on the ground at an airport to quickly calibrate to field elevation.


  • Vertical Speed – Vertical speed is displayed in the area to the right of the altitude tape.
  • System Warnings – Warnings will be displayed as needed at the bottom-center of the PFD.
  • Flight Plan information is displayed at the bottom of the PFD when a flight plan is active.


Note:  This instrument requires at least a functioning GPS to be valid.  However, addition of an Attitude Heading Reference System (AHRS) to the APIC network is recommended.
