It must be a pain in the rear for engineers when they know that actual aircraft windows are going to be popped for training because presumably some of them can be really tricky to put back in without damaging the seals, assuming they were not damaged during the removal. The training benefit to the pilot however must be invaluable especially if they find it difficult. I can understand maybe not having to remove actual windows if your role is an overland one but for offshore operations surely it should be mandated.
is there anyone out there that has never removed their window?
are there any types of helicopter difficult to remove the window from?
