Hello again,
No response after six weeks surprises me, I would have thought the 737 guru's in Pprune land would have found this interesting.
I am still unsure of how hot it would get in the case of a dual pack failure. The QRH makes a recommendation to maintain a minimum of 290kts once down at 10,000ft . This recommendation seems to be at odds with the MEL assertation that TAT is an important factor in cabin temps in this scenario.
Come on you knowledgable folk.......what's your opinion?
