Hi,
I am not very clear about the terms altitude, ground altitude and secure height used in the flight plan and relation between them. I am currently using basic flight plan for Microjet airframe.
Why does ground station show the current altitude some non zero value before the launch of aircraft. Shouldn't initial value of the current altitude of aircraft be zero? And is secure height relative to some predefined value or it is absolute?
Can somebody give me a short description about these term?
Thanks
Manish
