A related pig was/is getting an ADTS 505 set up correctly for an EGPWS
function check IAW AMM on a Bae146...
The static plate adaptor for S1,S2,S3 isn't the easiest thing to set up.
Then you have S4 for the BARC input BUT also (dependant on effectivity) there is the fwd outflow valve control S4 input - blanked during the check? - Memory getting hazy around about NOW!
As mentioned before, I despised the BAe146 once, not now though

Although sometimes, it does bite back & tears roll once more!
BAe146???
