REFLECTOR: pressure switch

[Geoff Gerhardt via Reflector]

Kevin,

I've had this issue, as well. For me, on the occasions that the pump doesn't come on when I flip the switch to lower the gear, if I push the reset button on the landing gear control (just need to push it briefly) , it will start the pump and put the gear down.  I've also wondered what the issue was.

I am wondering if it is an adjustment problem on my "up" pressure switch. Some times when I try to put the gear down, the pump will come on momentarily and then turn off. I then have to pull the pressure relief handle (emergency gear down) and the pump will come on. I then move the emergency handle back to closed and gear come down normally. This has always been there as an anomaly, but seems to be getting worse as I progress into flight testing.
