Instrument descriptions

Instrument numbers and descriptions*

*Current as of firmware release 1.06

Sample panel layouts (completely configurable)

320 x 240 screens

  

480 x 320 screens

The instrument number is used with the inst cli setting to select which instruments are displayed on a screen and what order. (you can have 6 attituded indicators on a screen if wanted). You can assign up to 12 instruments per screen on the 3.5" & 4" screens, 6 instruments on the 2" to 3.2" screens, and different numbers on smaller screens.
You can have multiple screens that you can change in flight. If your display shows 6 instruments, you will have 2 different screens. If your screen can show 4 instruments, you will have 3 different screens.
The description shows what data it uses from the flight controller

Images are captured directly from the screen buffer on the controller

1) Airspeed indicator

Speed data comes from either GPS ground speed or pitot airspeed. Pitot airspeed selected using the cli pitot command.
Speed displayed in knots or kph. Selectable with the cli unit command.
Vspeeds (colored areas) are settable using the cli vspeeds command. Enter vspeeds help for more info.
MSP data: MSP_RAW_GPS or MSP2_INAV_AIR_SPEED


2) Attitude Indicator

Attitude data from flight controller roll and pitch.
MSP data: MSP_ATTITUDE


3) Altimeter

Altitude data received from flight controller estimated position or from the barometer. Barometer selected with the cli baro command.
Altitude displayed in feet or meters and is controlled with the unit command
MSP command: MSP_ALTITUDE


4) Turn Bank indicator

Bank indicator uses data from the gyro.
Slip indicator uses the accelerometer.
MSP data: MSP_RAW_IMU


5) Directional Gyro with RMI

Direction uses the attitude yaw setting.
RMI points to Home (armed location)
MSP data: MSP_ATTITUDE, MSP_COMP_GPS


6) Vertical Speed Indicator

Vertical velocity received from flight controller.
VSI shown in feet / minute (future enhancement can show meters / minute based on unit setting)
MSP data: MSP_ALTITUDE


7) Airspeed Indicator alt

Speed data comes from either GPS ground speed or pitot airspeed. Pitot airspeed selected using the cli pitot command.
Speed displayed in knots or kph. Selectable with the cli unit command.
Vspeeds are not settable (part of background). Maybe future enhancement.
MSP data: MSP_RAW_GPS or MSP2_INAV_AIR_SPEED


8) Attitude Indicator electric

Attitude data from flight controller roll and pitch.
MSP data: MSP_ATTITUDE


9) HSI

Direction uses the attitude yaw setting.
The CDI uses the selected waypoint / runway and the HSI radio channel to set the desired course.
The radio channel is selected with the hsirc command (defaults to 10).
Waypoints can be set with the waypoint command and runways with the runway command. Enter waypoint help or runway help for information.
MSP data: MSP_ATTITUDE, MSP_COMP_GPS, MSP_RAW_GPS, MSP_ALTITUDE


10) RMI

Direction uses the attitude yaw setting.
RMI points to Home (armed location)
MSP data: MSP_ATTITUDE, MSP_COMP_GPS, MSP_RAW_GPS


11) VOR

Uses programmed waypoints and runways to set CDI and glideslope
MSP data: MSP_RAW_GPS, MSP_RAW_GPS, MSP_ALTITUDE


12) Tachometer - Single engine or left engine
13) Tachometer - right engine

Shows the RPM received from the ESC. ESCs must each be on their own output from the flight controller and it assumes the left engine is the 1st ESC.
MSP data: MSP2_INAV_ESC_RPM


14) Tachometer twin engine

It will show left and right RPMs.
MSP data: MSP2_INAV_ESC_RPM


15) Manifold Pressure - single engine or left engine on twin
16) Manifold Pressure - right engine

Pressure is displayed based on the servo signal sent to the motors. If the same signal is always sent to both motors (on a twin), both needles will always be together. If you plane is setup for differential thrust, it will show separate readings. Assumes the left engine is the 1st motor signal.
MSP data: MSP_MOTOR


17) Manifold Pressure - twin

Shows both needles.
MSP data: MSP_MOTOR


18) Fuel Flow - Amps

Amps is the overall amperage draw detected by the flight controller. There is not a way to get individual current draw on 2 ESCs.
MSP data: MSP_ANALOG


19) Weather Radar

Displays simulated weather
MSP data: MSP_ATTITUDE,  MSP_RAW_GPS or MSP2_INAV_AIR_SPEED


20) Aircraft Radar

Displays simulated targets - iNav 8.1 will support ESP32 Radar and display real data
MSP data: MSP_ATTITUDE,  MSP_RAW_GPS or MSP2_INAV_AIR_SPEED


21) Compass

Displays heading in a whisky compass format
MSP data: MSP_ATTITUDE


22) Fuel gauge

Displays percentage of battery remaining
MSP data: MSP2_INAV_ANALOG

 


23) RAF Airspeed

WW2 RAF Airspeed indicator
MSP data: MSP_RAW_GPS or MSP2_INAV_AIR_SPEED


24) RAF Attitude

WW2 RAF Attitude
MSP data: MSP_ATTITUDE


25) RAF VSI

WW2 RAF Vsi
MSP data: MSP_ALTITUDE


26) RAF Altimeter

WW2 RAF Altimeter
MSP data: MSP_ALTITUDE


27) RAF Compass

28) RAF Turn/Bank

WW2 RAF Turn/Bank
MSP data: MSP_RAW_IMU


29) Gear Indicator

Shows position of gear based on selectable servo channel
MSP data: MSP_RC

 


30) Flap Indicator

Shows position of flaps based on selectable servo channel
MSP data: MSP_RC
