Catching the Cabin on the 737
In my company we operate, amongst others, the 737-300. On occasion we catch the cabin on descent. This usually occurs when we have been at a high cruise FL ie 360/370, with no speed restriction below 10,000', no level segment other than to slow down and then a visual approach joining via a 3 DME final. It can be a bit of a hassle but usually predicted and negated by initiating an early descent using the Alt Intervene function on the MCP. However if we do catch the cabin it is often followed by grumbling from the captain along the lines that "this never happens on the 747/767/A320" the inference being that the cabin pressure controller (digital) on the 737 is crap. Now I may be just an F/O but it seems to me that on these other aircraft you usually don't find yourself with all the factors listed above combining at once. What are your expereinces with different aircraft and their systems?
