A1/ No
A2/ No
If I understand you right....there are your answers. The reason is that you don't know what the pilot is doing...how is he/she flying the plane, for all you know they could be adjusting power settings and not changing height at all.
About the only thing you could tell is that at 430 knots and turning one degree per second the bank angle of the plane would be around 16 degrees.
Give us the exact scenario and we'll try to be more helpful....eg why haven't you got a height read out from the transponder anyway??? Have the baddies turned it off???
