Centaurus,
What a wonderful construction, based on half facts, half fiction, and half wishful thinking, making 150% rubbish.
Before you work so hard on your RSI, why not do a bit of research !!.
Leadsled,
You certainly have a way with words old chap. Pity about the venom with which they are delivered if only because your attitude wreaks of scorn when well meaning individuals don't get their perceived facts right.
You are quite correct in saying that in earlier years, the first officer in QF was permitted to operate from the left seat when the captain decided. That may have originated from normal procedure in the RAAF on various multi-engine bombers and transports. The RAAF rules required the second pilot (first officer in civil parlance) log copilot time regardless of from what seat he operated.
Apart from the nasty little streak in the opening sentence, the rest of your explanation is informative and I am sure, factual. Thanks for going to the trouble of setting the record straight..
