B737NG unpressurized
Hi,
The MEL for unpressurized flight contains a chart that gives the cabin temperature and the flight deck temperature after 30 minutes of unpressurized flight with 45 POB. ( the max for dispatch).
With a TAT of -1 Celcius cabin temp = 21 degrees and the flight deck 24 degrees.
With a TAT of 10 degrees the cabin temp is 27 and the flight deck 35 Celcius.
I would appreciate your best guess on three questions:
1/ What is the TAT at 220kts at 10,000ft on an ISA day?
2/ What would the above figures increase to with 170 POB?
3/ What would the above figures increase to with 170 POB and 60 minutes duration instead of 30?
