What's your advice and technique for taxiing on very narrow, snow covered taxiways where the centreline and/or edge markings are not discernible? If you don't mind sharing.
Slowly, and ON the taxiway. If I can't see anything, I stop and ask for assistanse. Pretty basic.
Most western EK (OK, not Gods gift to aviation from down under) expat crew must have seen snow before. You operate the 777 to Europe and the US, so winter should be something to expect.
Don't tell me you send guys into winter conditions without sound knowledge about HOT, BA, Type 1,2,4, engine runups and so on?
