|  Pressurization question I'm studying for my aircraft systems final and i need to know how to caluclate rate of ascent for cabin pressure. any help?

| I'm supposed to be able to calculate the rate of pressurization in FPM. Such as "taking off from KPHX, if the airplane is climbing @ 2200 fpm to 21,000ft, and the max. desired cabin altitude is 8000ft, then what is the rate of climb for the cabin pressure?"

So we want to ensure a cabin rate of climb that gets to 8000's before the airplane levels off. KPHX is about 2000' (Make sure I've got this right...I'm guessing)? So about 8.5 minutes to climb to FL210. The cabin needs to climb 6000' in 8.5 minutes. So 6000/8.5 = about 700 fpm. This rate of climb seems a bit fast to me...but most airplanes will be able to maintain a lower cabin pressure than 8000' at FL210. | |
