Crj Aoa

[mnttech]

Hi,
On the CRJ 200/700/900, are the AOA transducers just a standard transducer, i.e., feed it 26VAC and it has an XYZ resolver type output?

I think the part number is a 25147A -x depending on installation.

Thanks,

Probably want to try the engineers forum with this one......

The standard Thales AOA transducers are either part number (P/N) 45150340 or P/N C16258AA, which I believe are interchangeable on CRJs but only one of which applies to the CRJ700/900. That's what the aircraft comes from Bombardier with.

There's also a BFGoodrich STC vane for the aircraft, which might be the one you're asking about, since the part numbers seem not to agree. Unless we're comparing OEm p/n and vendor p/n of course.

Afraid I don't know much about the internal gubbins in the AOA sensors, though.:(
