Hi
Manoir (John),
I guess that when the photo of the Chipmunk was taken you might have been starting your Instrument Rating course, flying the Cessna 310? If so, you'll remember the problem for procedural stuff was that the 2000-foot wind rarely fell below 40 - 50 kt in that spring of 1967 - generally from the west. It made an ILS on Rwy 13 at Turnhouse - that aerodrome's only ILS in those days - particularly challenging, and even one on Rwy 31 at Prestwick. ADF approaches were rather more tricky! 25 degrees of drift was common, and rough with it. The absence of any DME made all ETAs a lottery, based on the forecast wind. The same applied to holding patterns, which were supposed to be completed in precisely 4 minutes in those days; meaning the timing of the outbound leg and the tripling of the drift were critical.
So three C150s flew to Dyce "in loose formation" for the solo pilots to perform their qualifying CPL X/Cs? Which one did the navigation?
