Hi
If
1) I aim the camera directly forward and
2) fly to the top of an obstacle and
3) position the top of the obstacle in the center of the screen and
4) read the altitude
is that a accurate measure of the height of the obstacle or
is there distortion/whatever such that that is not an accurate measure
why do I care?
we have some tall fir trees on a hill and would like to set RTH altitude to be greater than the firs/hill
I could just say 200' and let that be that but
I flew to the top of the firs, put the leader in the center of the screen and read 106'
so am wondering how accurate is 106'?
thank you
