GPS based FL - Flight Level

Postby kitercuda » 09 Jun 2019, 17:46

FL level is used for flying over transition altitude and for determining if you are inside of airspaces (I mean airspaces which vertical borders are defined by FL)
If your device has Baro (pressure) sensor and your aircraft has not pressurized cabin, you can display Baro flight level at your screen (long tap at the compass rose and select it). It is QNH independent, application set for calculating QNH to 1013 hPa (29.92 inHg).
Altitude strip (blue background) displays Baro altitude. So if you want to see flight level at altitude strip, you must set QNH to 1013 hPa (29.92 inHg).

If your device has not baro sensor, and you want to see GPS based flight level, you must set correct QNH. GPS flight level displays correct value only if you are flying in area, where is QNH 1013 hPa (29.92 inHg). If there is QNH different, GPS flight level displays incorrect value. But if you set correct QNH to application (long press to FL window), application calculates the difference and uses it for displaying flight level and airspace warnings.

I juste re-tested with the latest version and the QNH input is now possible.
Thanks for this new function!
