Taxi in on one engine
On a recent Flybe flight, I noticed we taxied in on one engine. I know this is common place with EZY, but I assumed in the airbus the SOP would be to have the APU running to do this?
My understanding of the dash would be that you need AC power for the hydraulics to work. With only one engine, you are relying on that one generator for your hydraulics, it would only have to click off and you would have no steering at all.
Have there been any cases where hydraulics have been lost during the taxi in on one engine? It would only take one even small incident to wipe out any cost saved on fuel burn.
