Cougar TQS Comm Switch IFF IN/OUT
-
what does IFF IN/OUT mean on the TQS comm switch?
i read about using TMS right to interrogate but no mention of the IFF IN/OUT.
there are other functionalities but is there one related to IFF? -
To interrogate you use TMS left actually, TMS right is for RWS>TWS and TWS target stepping in CRM mode.
I also wonder why the comm switch had positions called IFF in and out. Maybe some earlier blocks made some use of it? It is normally used for L16 and IDM, at least in later blocks.
Another misleading thing is IFF ident button, it is not really related with IFF but with mode 3/A transponder and serves the same function as so called ATC ident buttons in civilian aircraft.
