Question

What is rate of climb "referring to cabin pressure".?

Answer 1

Rate of climb = How fast the airplane is gaining altitude.

Cabin pressure= The apparent air pressure inside the cabin at an equivalent altitude.

Basically, if cabin pressure was 8,000 ft above sea level, it's the same as standing on an 8,000 ft mountain, even if the aircraft is at 35,000 ft.

Most small airplanes are not pressurized, so cabin pressure is always equal to the pressure outside.

However, most larger airliners and transport aircraft are pressurized, so they can climb well above 8,000 ft, and the cabin will have the equivalent air pressure of 8,000 ft.

Answer 2

CAA (EASA) Module 11 answer:  The rate of climb for cabin pressure is 500 feet per minute.  The rate of descent is 300 feet per minute.

Answer 3

If you meant cabin pressure rate of climb, then it's actually how fast the aircraft regulates the "drop in air pressure" inside the aircraft. Remember, as altitude increase, the air pressure decrease. So, if you're flying in a pressurized jet with a flight rate of climb of 2000 feet per minute, the aircraft is regulating the drop in cabin pressure to a comfortable level of 400-500fpm. The same principle also applies for descent.

So, imagine if you're flying on a jet without pressurization, how that 2000fpm change will do to your eardrums... :D

Answer 4

A 737 climbs from S.L. to 36000ft at 2000ft/min. This takes 18min. So 0ft to8000ft in 18min = 444ft/min cabin rate of climb
