"Asymmetric reverse works wonders when conventional directional control becomes a problem."
Worked well on the Electra usually, although I had an interesting experience in Gothenburg early one morning when a less than delicate captain had us going forwards, then backwards, then not sure, in a white out with fresh snow on top of sheet ice on the apron. The marshaller was not impressed!
Mind you, one of the local F27 operators did a full aircraft width, 5 wheel drift as he came onto the apron, he then taxied very, very slowly.
