Climb Vsi
How will the aircraft instruments reading change when it is being subjected to unusual attitude?
In unusual attitude, I mean when the plane is vertically climbing, diving, upside-down.
You know, the stuff those aerobatic planes usually do during air shows.
I only need to focus more on the basic 6 flight instruments (ASI, AH, Altimeter, VSI, DI, Turn/Bank coordinator)
Depending on how hard of an turn or ascent or descent you do you could cause your gyroscopic instruments to tumble. The gyro instruments are operated on the premise of rigidity in space where the gyro maintains a steady position in relation to the horizon while it is spinning. So as an airplane maneuvers, the spinning gyro maintains the same plane in relation to the horizon. The instruments are then calibrated to show how the airplane is rotating against that gyro. If excessive force is put on the gyro it will tumble, meaning the spinning gyro is now not spinning in relation to the horizon and can give false readings and on some older and simpler aircraft the instruments will roll around uncontrollably. After around a minute the gyro will stabilize and once again start spinning with the horizon and the instruments will show the correct reading.
