Hitech,
1. Having to get back out of the air plane, just because you left the key in your pocket and can't reach it while in your plane.
I hate that!!!!
2. Having to dispose of other peoples air sick bags. Allthow track IR has that effect on me.
Once threw one out of the window of a 172 while flying over midland MI, because it was making everyone else sick
3. Having to get out the jumper cables because some one left the master switch on.
Quite a fan in the winter months, I need a new battery.
5. The bloody brightness control on the gps, that I never seem to rember how it works when it is all dark and you can't see the display to adjust it in the first place.
You would think they would make the screen red so it would not screw with your night sight, I put a piece of red plastic over my screen, really helps.
