Hi All ...
I thought this diagram might stir a few memories for quite a few ... especially given the reminiscences around "checks" in the last couple of replies. I have to say that this diagram comes from the 3rd Edition of the AP which was originally issued in June 1966, where I recall it was replaced in the early/mid 70's by a 4th Edition (?) ... which came in a small blue plastic ring-binder if my memory serves me correctly (which was difficult to stuff in the leg pocket of your flying suit unlike the earlier editions !) ... by which time the Carb Air setting was declared "wired hot" in the FRC's and the use of the Landing Lamp for anti-collision purposes required you to switch it on before take-off and then off after landing.
Kind regards ...
Coff.
