Thanks again Fargoo,
The Marker is always received and monitored by the left VOR on the 757 regardless of what ACP type is fitted.
I didn’t know that. But why then do ‘usual’ 757 panels have a separate Marker select?
I
think the panel above is from the BA series of 75s which were modified for MLS trials. With Airbus and MLS ‘provisions’ the ACPs have MLS and Marker. A-320 Below. Still curious, and I'd appreciate it if you'd check the wiring manuals to confirm Marker on Left VOR. Not that I doubt you - just never heard it mentioned before.
