What if they have Pressure gauges,then weight check is not called for
I can't recall having worked with an engine or APU fire bottle that had a pressure gage. But it is early, and I haven't had my coffee yet.
Most I have worked around had a disk on the fuselage, or engine pylon that blew out if they were used.
They didn't even equip the B-52, in any model, with engine fire bottles. The KC135A model did not have fire bottles for the engines either, the other models of the 135 I can not speak for.
I witnessed one blazing engine fire on a 135A one day, they could have used some fire bottles. The #1engine caught fire right at rotation, and he flew around dumping fuel out of the boom while the fire was burning off the contents of the oil tank after it had burned through the oil lines. To add insult to injury, when the airplane rolled to a stop at the end of the runway, a newbie fireman ran out and buried a fire axe in the nose cowl, ruined a perfectly good nose cowl. Then for an encore, the crew left the battery switches on when they evacuated, and the fuel gravity feed to the aft fuel tank, which caused the aircraft to come crashing down on the refueling boom. Wish I had a camera for that one.
