Re: Taxi out on one engine?

On a 787 it would be a no brainier really. During training I was told by Boeing instructors that Boeing didn't recommend it - unlike the 'Bus, which has appropriate SE taxi procedures published in the FCOM. I stand to be corrected, though. If there's any official Boeing guidance on this, I would lo...

Re: Taxi out on one engine?

Single taxi out worked like a treat on the ATR, however, it gets more complicated as the size of the airplanes increases. Did it a couple of times on the A330, but scared myself in the process. To get the thing moving, I needed a handful of thrust and those big engines can make a lot of jet blast, a...

@RJMAZ, Reserve fuel is only used to obtain the landing weight, which in turn is required to get the fuel burn values. The resulant fuel figures are only trip fuel figures, ie. fuel burnt from takeoff to landing. If it makes you happy, we can assume eg. 6T of reserve fuel for the 788, but it will on...
