How accurate is the barometer for measuring height? If within wireless signal, does the aircraft take topography into account to report AGL height? Or is it simply a blind difference in assumed height between the aircraft and the starting position?
It seems like barometric pressure is a wildly innacurate way to measure small changes in height, especially where there is changing air velocity and prop wash.
Also, I experienced a connection loss yesterday while flying in hilly terrain and accidentally going behind a ridge. The aircraft stopped and retraced it's flight path until connection was reestablished. Not wanting to accidentally go suddenly out of signal range again, I used RTH to establish a direct heading to home, and then retook control of the aircraft.
My current settings are to initiate RTH on connection loss, but that's not really what happened here. Will this retracing of the flight path always occur? Are there settings I can choose to encourage this behavior?
When I did select RTH, the aircraft didn't drop to my specified RTH height. Does the aircraft only use the specified height if a climb is required to attain that height?
Finally, the manual that shipped with the Phantom was very brief, and the tutorials seem extremely basic. Is there better documentation available so I don't have to bother you guys with questions like this? If so, feel free to just point me there and tell me to RTFM rather than take time to answer all of my questions.
