A perfect example of this was when I was with the original Pan Am. We had two serious-injury incidents back-to-back - one at MIA
and one at JFK
- involving personnel injuries while opening the A300 passenger doors. It seems that with as little as .5 differential PSI, it is still possible to open the A300 door however, at that differential PSI, the door opens with a force of over 845 pounds! The poor operator of the door who is unfortunate enough to open it with .5 differential PSI, is launched like a toy airplane!
Since Boeing designs their plug-type doors differently from Airbus, the same situation does not occur. Instead, with Boeing aircraft, if you leave the air conditioning packs running and everything else closed up, you may not be able to exit the aircraft or, if you've left it powered down and closed up, with the ground air conditioning attached and running, you may not be able to get back into the aircraft later! (I've seen this happen a few times and it is
embarassing having to wait until the pressure bleeds off so that you can get into the aircraft!
