I fly an old military aircraft that is seriously overdue an avionics update but probably won't get it for lack of money / time remaining in service. For 20-something years I selected SBY before changing squawk. Then a few years ago I was told to leave it on, because of TCAS and separation being done against me when I show on SSR only - I think that was the rationale.
I do take care not to scroll through the emergency numbers.
But back to the opening post - what is the policy - can anyone quote a definitive document?
I would have trouble challenging the position of my trg staff without a policy document to quote.
