pressure?
Am I being silly here? What is the air pressure inside the cabin of a typical pressurised passenger transport flying at a Pressure Altitude of 35,000ft.
Please select your answer from the options below:
a) It's 35000ft you plonker, you just said so!
b) Oh no it isn't because you don't know barometric altitude!
c) Are we talking Airbus or Boeing here because it all depends!
d) Would it be about 5000ft perhaps? I mean roughly.
e) This could never happen in a TriStar
f) This could never happen in a B777
g) Couldn't happen in an Airbus they can't accelerate, far less climb.
h) Can't happen in a B787, they can't even take-off.
i) It all depends on Mach No because it just does.
j) None of the above.
I think you want something that detects an acceleration of about 7 ft/sec/sec for about 45 secs then the rumble stops; the pressure moves towards about 5000ft then stabilises provided they've remembered to click a few switches up front; it can detect a few "ding-dong" chimes inside the next 20 mins; then detect the sound of 150 seat belts unclicking etc. And then it turns the phone off.
Sorry. I must be missing something vital here. Acceleration, pressure, flying. Oh no...., it's a wind up. Well done!
