737 cabin altitude question
A question for all you 737 jocks:
Since the 737 differential pressure schedule is lower than other Boeing planes (probably due to the fact that this model was designed for multiple cycles), cabin altitude tends to be on the high side (around 8K feet when you cruise at 37,000 or higher). Do you get any complaints from cabin or flight deck crews related to the high cabin altitude (especially on flights of 4+ hours)? Does your airline limit cruise levels due to possible risk to pax and effect of low O2 levels on flight deck performance?
