I used to be in the spacecraft business and, there, when you asked the reliability guys for some numbers all they wanted to know was the number of connections in the bird. My avionics shop said it fell apart like a cracker when opened up. A servo motor that requires a higher voltage to get moving will also cause the same problem. If a particular mode of operation, including ALT Hold, develops a fault peculiar to that mode only, it is acceptable to operate the system in other modes as long as a determination can be made as to their satisfactory function. There is a membrane behind the buttons that deteriorates which causes the buttons to not work. Pitch axis control is provided for the altitude hold function by use of the accelerometer and the pressure transducer. When first engaging Altitude Hold, the system will often lock on an altitude that is slightly above or below what you intended. Sep 3, 2022 · I just had this same problem a few months ago. Occasionally it can be water in the static system to the altitude transducer but this is much less common.
