Running firmware 4.00 (latest at the time of writing), the D2 Charlie still suffers from the following nuisance/bug:
Even though Aviation Units are enabled (e.g. elevation in *feets*):
- altimeter (widget) *calibration* is still shown in the "system" units (e.g. *meters*)
- FLY (app) *vertical* speed is based on "system" elevation units (e.g. *meters/minute*)
This makes:
- the altimeter (widget) a *nuisance* to calibrate (e.g. based on current airport known reference altitude)
- the FLY (app) *dangerous* (since meters/minute are close enough to feets/minute to be easily mistaken and the discrepancy not obvious)
