Right now I just pry it back into the track and whack it with a rubber mallett. Which usually lasts a few days then I have to do it again.
Dennis is correct. To add to his remark, there is little benefit to external monitors in an emergency situation. If the engine is on fire, or you lose a section of the tail, or whatever the video can be fairly poor for relaying information. Now they are beginning to install an infered camera for seeing the run way in a clouded or fogged sky. The older aircraft as Dennis illudes to, was very crowded with steam guages, but now we have the ability to change between video sources easily more cameras will begin popping up on the aircraft. We we ill see how usefull they are in years to come.
That's normal. It's just the dust that has collected over the warmer months. Sounds like you have a very sensitive and, therefore, a very good smoke detector.
If I were the angry sock puppet, I'd be afraid.
