B737NG Pressurization question
Here the scenario:
Flight plan filed is at FL360 on a 5hr flight plan. There are two step climbs later to FL 380 and 400.
I always put the filed flight level (FL360) into the overhead cruise altitude selector. When we later climb to FL380 I put that in there.
I just flew with a guy that ask told me another guy told him (...and so forth) that if you right away put in your final cruise altitude (FL400 in this case) while still at the gate you will not get any pressure bumps when you step climb later at altitude.
Now, I never noticed any pressure bumps when doing it my way, but he said that his way the computer would know the final altitude and avoid the climb of the cabin when step climbing.
What do you think?
