REFLECTOR: BLUE MOUNTAIN AUTO PILOT

Tom,

If you suspect the data port on the EFIS, you can test it separately by
connecting a laptop with an Ethernet crossover cable.  If you can FTP to it,
the EFIS side is not the problem.  This will eliminate one possibility.

As part of the testing process, I had already set the altimeter to 2000 feet
above my field elevation.

I am wondering if it is more likely the AP control module or the EFIS data
port.

Tom,

The auto pilot is designed not to let you engage the auto pilot on the 
ground and will disengage at I think it is 500' AGL so that you can't fly a 
ILS approach below minimums. Change your barro altitude to 500 to 800' AGL 
and it should engage. Or at least that is what I have read on the reflector.

I have the BMA system, but I'm not that far yet with my install.

Andy
