We used to taxi in and out with a single Spey shut down on Tridents ... No minimum warm up time either . Only came in with Rb211s.
737-200s ,once APU on line taxi on one JT8 , occasional skipper shutting down the 2nd B4 gate entry . Had to be a nicely judged decel , otherwise you stopped short and had to restart ! No probs with brakes , hyd , elec , systems etc .
Tristars ,747-400s , Rb211s taxy out , in 1 shut down [ under a certain weight ] .
747-400 , JFK one bad night , over the above wt , out of the ramp onto taxiway , looked at queue ...shut down 2 engines . Even with extra taxy fuel , only just got to the runway with minimum take off fuel ...... 2hrs 15minutes taxying !
Others had to return to the gate for more fuel ...
Worst spatial disorientation .... new to 747s , taxying to tight gate in San Fran , creeping in for last 2 yards . Ground staff start moving the pier towards the [front left] door1L ; gives an illusion of a/c shooting forward . 15 stone jumps on the brakes , 250+ tonnes does a 9 G stop , junior stewardess at door 4L flies forward , up the stairs and lands in my lap [ wishful thinking , that one ] . Have to then reevaluate , and move a/c forward 4 feet . Try and explain that to 300 pax and crew ! Had to buy a few beers that night .
