My questions are, in a developing emergency down manning scenario:
1) How long would it take to turn around a helicopter, i.e. from landing to pick up crew then take off?
2) What is the minimum time gap between one helicopter taking off and the next one landing?
I don't know where this goes, but anyway.
In the shuttling scenario with absolutely helicopter-inexperienced people, some have never seen a helicopter in their life before, I have a turnaround time of usually 45 seconds which include disembarking of 5 to 6 pax, unloading their luggage, hot refuelling, embarking and strapping in 5 to 6 new pax and loading their baggage.
When things go very slow I have a minute to a minute and ten.
Now that's in a 407.
Boarding 16 experienced pax in an emergency shouldn't be much more than that. Especially when the machine comes in empty not unloading anybody.
2. I'd say about 20 seconds.
