Is INS drift affected by aircraft condition/wear and tear?

[Stickler]

Simple question: Does the condition and wear and tear of the aircraft have any influence on the amount of INS drift accumulated during a specific period of time given identical aircraft movement and external conditions? Or put another way, do different non-reference aircraft accumulate INS drift at a different rate?

[Zabuzard]

Yes, the entire aircraft is subject to these settings.

For the INS specifically, there are around 40 components in and around the INS system that are affected by condition/wear/tear which will some way or another influence the system.
We simulate INS drift in detail by actually moving the gyros around and such. There is no magic here, the drift happens the same way as it would happen IRL and all the small parts that play a role here can degrade in multiple ways, influencing the system highly dynamically.
