Spent many happy years fixing the Queens own Tristars. An avionics gem if you like your autopilots with fingers in everyones pies.

8 years tanking for the Bosnian campaign, and 99.9% despatch reliability. Not bad...

Engines that don't need a ground run post change. And don't make you deaf as they pass.

Multiplex systems for getting muzac to the pax, which did wierd things when you unplugged bits.

Bongs that would go off on the approach for no reason, and could not be turned off.

Flight data recorders that proved the pilots were downright liars on more than one occasion. And saved you changing engines every three weeks.

APU's everyone could fire up to get the inside toasty or chilled as required. And a galley for 24 hour coffee.

A FESC and MESC the riggers didn't understand and rarely visited.

Wierd powered doors you had to have power on to close.

A HSC the fairies hated and avoided like the plague.

An SLB half way up the damn tail.

Linear Variable Differential Transformers. Don't think I'll ever forget that bizzarre description.

Camera control units squeezed between the HDU and the side wall. And camera's an eith of an inch shorter than the dome they live in.

Ah, sweet memories...

"A FESC and MESC the riggers didn't understand and rarely visited." Must have been lazy riggers and how did they change PFCVs without going through the MESC????? As an A & C man i'd rather not be in either though, especially removing a fwd waste tank!!!!

Out of interest what AMM allows an engine change with no runs, i'm sure the RB211 AMM on the TriStar would have listed some of the engine tests?? Even a modern FADEC engine would have an idle leak check!!!

They just do a check start, and turn it off again IIRC. Let the electronics monitor the rest.
