Keller" : Marv: Interesting note and drawing you appended to Barry Knotts' post. Not being familiar with the L-IV gear mechanics I assume from your comment about the gear-up switches that the gear leg activates the switch. Will that also ensure the doors are closed? On the LNC2 it would seem it would be better to activate the up switch with the inboard door rather than the gear itself. Also, why do you have one 18AWG wire in a circuit otherwise wired with 22AWG? Am I missing something? Charles --- [Yes, Charles, the gear legs actuate the up switches. We did not annunciate the doors themselves. The nose gear doors on the IV are actually held in place by the strut pulling their actuator up, and we are just assuming that the springs are going to do their jobs and hold the main doors closed. I guess you could annunciate the doors in lieu of the gear and apply the "if a = b and b = c..." rules allowing you to assume the legs are in their proper positions. On my LNC2 I'll be removing all of the hydraulic inner gear door stuff (weight reduction) and close them mechanically (not the original cable method, something more positive and simpler), so those doors closed will truly indicate the gear tucked up. As for the one 18 ga wire, I had a problem adequately supporting segments of the run between the two switches so used the one heavier wire to provide a backbone of sorts to help stiffen that little bundle. ]
