I know this has been discussed before (and I will do a search to try to find the answers), but I want to pose the question in a slightly different angle:
1977 turbo-Arrow: the "in-transit" gear light will sometimes come on during cruise. After a while, it will go out again. There is no obvious change in performance or suggestion of increased drag somewhere. I'm not positive, but I think I've heard the gear motor activate for a short time (maybe less than a second) when the in-transit light extinguishes again. My understanding is that the pressure in the system slowly bleeds off, and gear sags slightly (enough to open one of the switches and illuminate the "in-transit" light. Eventually, the pressure bleeds off below the limit set by the hydraulic pressure switch, the pump activates and sucks up the gear again.
My problem is that I have an Avidyne TAS 610 TCAS system...when the gear sags and illuminates the "in-transit" light the TCAS goes into "ground mode" and no longer looks for traffic....bit of a problem in the air since it gives a false sense of security.
My question is: what are all the different possible causes of the pressure bleed off and the gear beginning to sag?
Thanks in advance to all the great minds on this forum!!
