Rapid decompression
Ok folks, a rather strange question perhaps, but one which would help me massively....
The situation is that you're flying a 777 at about 27K, a hole is created in the side of the fuselage (say for arguments sake about 75 x 75cm). On the MFD, CAB ALT ramps up straight away until it equals outside pressure. The pilots then make an emergency descent at approx. 4500 ft/min. My question is: would/should the output shown on the display match the actual rate of descent of the A/C?
Many thanks in advance!
