Hydraulics pressurised - Fuel system pressurised ???
As a retired F/E I find it interesting that you guys would even suggest leaving the hydraulics pressurised and the fuel pumps running during ground time. Fuel pumps do have a finite life and running them whilst they are not feeding an engine is certainly not good practice in my view. Some of you may recall a Phillipine Airlines B737 burning on the ground in the late '80s at Manilla. Running CWT pumps without fuel in the tank was cited as the cause. As for hydraulics being kept pressurised during turnarounds it is simply dangerous. I am darn sure there is a very good reason for getting a clearance from your friendly ground engineer before pressurising hydraulics whilst ground personnel are moving around the aircraft. I know I wouldn't be sticking any part of my body in a wheel well or near any hydraulically powered component without knowing that (a) the system is depressurised or (b) if it was pressurised I was in contact with the cockpit. Quote: "One less thing to forget at start-up" in relation to these issues. You have got to be joking!
