Does anyone know of a parallel track can be set up on an IFR approach?
I do not know what equipment was fitted to the aircraft in question, but all IFR (TSO C129) GPS's I am familliar with (Garmin and King) do not have the capability to fly offset tracks, and I would seriously doubt whether any with that capability would allow that when flying an approach.
When flying a random track like that being flown there would be no need to offset a track anyway.
The only GPS's I know of which have the offset track feature are handleld VFR gps units, such as my garmin 196.
