What do you all think of the policy in my company which dictates that - at a certain airport in China - we should not start the APU after landing, but taxi in and park on gate with both running (for noise and pollution reduction reasons), and wait for external power, which always takes several minutes to actually connect?
Personally I think it's an accident waiting to happen, and a self defeating policy anyhow. Two big engines running for two minutes versus an APU running for maybe 4 or 5 minutes!
