I am wondering why we measure for attitude of an aircraft its angular rate (instead of angular acceleration) and for the translational channel the acceleration instead.
The computers can integrate both signals to get the current attitude and position of the aircraft.
In another question on this forum someone stated:
"I think that the biggest problem is that in a coordinated turn, the angular acceleration is 0 and the lateral proper acceleration is also 0, so without measuring angular rate, an IMU would be unable to distinguish a coordinated turn from straight-and-level flight! That's a critical flaw."
To my understanding: if a computer just integrates the signals you will know your attitude and position. So in order to me more precise one should use the acceleration values (and reduce the bias/Drift).
Can you help me in this?
