Thanks H Peacock,
I have seen the three versions of LEMO, but as you say, the three aircraft - it's tempting to correlate them, but knowing the logic of the air force, I doubt it's that straightforward!
The documents I found from 1975 and 1983 in the link shown both show a type of LEMO connector, but not which one. I then have it reported by two people that standard NATO connectors have been in use too.
I'd love to unpick the illogical logic of this, but I'm going to need dome help!
It's going to be a matter of piecing together eras / roles / equipment needs etc.. to decipher which interfaces are used for what, and were used when!
With the power supplied for NVG's, did ANR headsets ever get supplied through the LEMO connectors too? (did Tornado crews use ANR headsets in the helmets? I've seen them on Jaguar with the external battery pack)
And then there's Jaguar and Harrier, but let's not go there for now!
Cheers, Scott
