LW aircraft speed specifications

[Crumpp]

You misunderstand, when retreating in Russia the Germans destryoed their equipment as best they could before it was captured. Obviously this depended on what resources and time they had left.

One way I read about was heap them all together and burn them. Smashing the dials with a hammer or submachine gun... Going to need more than calibrating after that... Crash landed aircraft may or may not be damaged. Did rounds enter the cockpit? Were the dials broken in the landing?

However I agree with you, different manufacturers use different tolerances and different methods.

Absolutely. They did not want equipment to fall into Russian hands. It is highly unlikely that the Russians could fly any captured equipment without extensive repairs.

Even the jolt of hard landing can knock the instruments out of calibration.

If the Russian's calibrated German instruments, they would induce an error from the begining.
