Which brings to mind the question of what procedures AC used to deal with this situation for older aircraft, without a FPA facility?
And also, for an operator that spends a good deal of its time in winter operating in sub-zero temps, how can they devise what appears to be a less than ideal method for its crews to conduct NPA's in said nasty conditions. One would have thought they were expert in winter ops: and how can that apparently less than ideal method have been approved by an equally supposed winter op experienced XAA? And if their methods are less than ideal, what have they done about it, and been required to do about it PDQ. It's already getting cold up there.
Is all that off target or am I misunderstanding?
