Airbus Single Engine Taxi

Why does the FCOM state that you must be taxiing in a staight line when you shut down the engine? Any answers with a link or a technical reference (Book/Publication) would be most appreciated.

I don't know anything about Airbi, but on the Challenger generator changeover can trip the nosewheel steering. If you're going straight the biggest risk is not noticing as it's a complete non-event. Half way round a turn can be a bit more exciting though.

My guess

Presumably because, as the steering comes off the Yellow Hyd system and you are about to shut down the yellow egine pump, it is a good idea not to be actually using the steering system at the changeover time.

Once you OK with the electric pump in control you can steer away to your heart's content.

Although that's not categorically stated in the FCOM, all the info is 'buried' there.

Depends which type you're talking about. Not so on the A300/310 as it's the Green system which controls the nose wheel steering.
