We took off with the APU on in the CRJ as a regular procedure.

Curious what the reasoning is.

When I flew the Reset Jet, normal procedure (at our company) was to shut down the APU sometime during the taxi out to the runway and transfer the bleeds over to the engines. But if you needed wing and cowl anti-ice you took off with the bleeds on the APU, or else you took too much of a performance hit. But the APU was then shut off in the climb check.

On arrival, you'd keep it off unless again, you needed both wing and cowl anti-icing. But much like on some airplanes, using just the bleeds on the engines on the ground provided almost no A/C. It was absoulutely terrible to be stuck with a deferred APU and a long ground stop. [img]/ubbthreads/images/graemlins/banghead.gif[/img]
