B737 + B767 Pressurization
Could someone please help me out with a knowledge gap.. So far I'm unable to locate in the FCOM's.
What is the reason that the LDG LT is set to 9,000' (B737) and 9,500' (B767) when running the QRH checklist? From memory it was something to do with the outflow valves but my memory is failing me.
Thanks in advance.
