Hello to all, I was checking out diagrams of the electrical system for the 767. I noticed on a secure aircraft all you need to do is to hit the Battery switch, Standby power, then APU etc. Correct me if I am wrong but this does not sound like a secure aircraft to me being because in single engine planes I fly we use a key for the ignition. I know there are no magnetos on a jet but would it be safer if there were a key inserted somewhere before you can turn on the battery? Lets face it what would keep a person from just getting on a jet and starting it up by hitting the battery switch and just continuing the flow. Thank you :-wave

"Lets face it what would keep a person from just getting on a jet and starting it up by hitting the battery switch and just continuing the flow."The man/woman with the big gun at the front door who sees you have no airport ID, barbed wire fencing around the airport, irate engineers with large, pointy, sharp tools seeing you tampering with their airplane, etc ;-) Can you open (and close) the cabin door? Then there's the problem of removing the chocks (which sometimes get jammed under the wheels to the point where you need a tug to move the aircraft (slightly) to free them), backing the airplane out of the gate without overheating/destroying the engines, airport vehicles parked in your way to stop you (intentionally or otherwise), gear and nosewheel steering lockout pins, pitot system protective covers* (how fast am I going???), etc.... If the windows on, say, a 767, are open, can you close them? (otherwise it might get a bit cold/windy when you get to takeoff speed).These are just some of the things I can think of.Cheers.Ian.*How tall are you? You'd have trouble removing these :-)

Ian,you forgot some - the Big Aggressive Dog - usually Alsatian or Doberman that walks around with the person next to the person with the Big Gun.the fact the aircraft will not have been fuelled since it's previous sector. And the Dinosaurs that some airlines insist on employing as Cabin Crew. If only every airline employed the same recruitment people as Virgin.

"the Big Aggressive Dog - usually Alsatian or Doberman that walks around with the person next to the person with the Big Gun."Ah... however, due to Australian quarantine restrictions, our guys have to use attack "Tasmanian Devils". If your leg is missing large chunks of flesh...and bone, you know you're in the wrong place ;-) "the fact the aircraft will not have been fuelled since it's previous sector."Should be enough to get the airplane started, though.... and perhaps even take the aircraft to the end of the runway (if the engineers haven't been using the APU too much)."And the Dinosaurs that some airlines insist on employing as Cabin Crew."True. One look from them could turn you into stone (especially if you ask for a second glass of orange juice). Sometimes they just beat you about the head with their walking sticks if you cross their paths when they're pushing the dinner carts down the aisle.All in good fun ;-)Cheers.Ian.
