Wheel fire... or not?
A gound engineer reported smoke from the MLG to the Qantas 744 after landing in Sydney (yestarday or today...).
The captain ordered an evacuation -> a chute collapsed -> passengers got injured.
Apparently there was no real fire.
The captain decided to evacuate after the smoke was reported.
My question: why didn't he ask what colour was the smoke?
If the smoke is white, it's just an overheat or fluid spillage on hot brakes.
If smoke is black, then you have a wheel fire and should evacuate.
Or not?
