Thanks Aerocat, aah the S2 (never had the pleasure).
You are correct, just found my reference. This makes sense with the VOR as bearing information, the ILS as a beam.
The GS display had conventional scaling, and presumably suffered beam 'reversal' at excessively large deviations (as for a 6:1 glide).
Also was the DME powered as part of Nav 1 and displayed on the DBI?
Oh for a list of all those forgotten things ... at least I know that they are forgotten, ... I think.
