I once took a flight with a CFI out of AUS
(great pilot by the way!) and in a Cessna 150 (or 152.) He did the engine run-up during the taxi on the taxi-way parellel to the runway.
Is this typical? I had always though (as was always happened this way), you did the run-up either at the hold-short or in a designated pad at the runway end.
One thing I can think of is at AUS
this particular taxi-way (Bravo, parellel to 17L/35R...we used to 17L, taxiing from the Trajen ramp), intersects a cross-taxi-way that an AA
Mad Dog was using to pull in front of us. Perhaps we had a better chance of slipping onto the runway before them if we were ready by the time we got to the runway entrance?
