Android app for pilots that monitors altitude and outside air temp from avionics to automatically calculate max cruise engine torque, fuel flow, and true airspeed for Pilatus PC-12NG / NGX aircraft. Works with the following Wi-Fi access points / gateways:
- Aspen CG-100 ("Connected Flight Deck")
- Emteq eConnect
- Gogo
Supports 4-blade and 5-blade aircraft S/N 1001+ (for NGX, assumes 1700 RPM mode). Data consistent with eQRH tables and POH tables using interpolation. Reported torque and fuel flow assumes a 8000lb weight. Airspeed is a function of weight.
Figure 1: Screenshots from app
The app has a simple/clean UI and supports dark mode for night flying.
Data refresh is attempted every 5 seconds when the app is open. If the data is stale (older than 1 min), the text outline boxes will turn red and calculated values will be displayed as ---. The age of the received avionics data is shown in seconds/minutes.
The aircraft type, avionics interface, and weight can be configured from the overflow menu and is persisted across app restarts. The auto-detect avionics option is useful if you switch the phone's Wi-Fi networks mid-flight.
Warning: THIS APP IS FOR DEMO/MONITORING PURPOSES ONLY. It must not be used to set engine torque. Always refer to the manufacturer's QRH or AFM for authoritative engine settings.
