Re: Tire temperature?

Brake Temperature Indications are used in many aircraft types, but I don't know of any aircraft that has a tyre temperature indication. On the A320 takeoff is only authorized if the brake temperature is less than 300C. The objective of the limitation is to avoid a fire in the gear bay - if there wa...

Re: Gate or Stand

I've always understood the 'gate' to refer to the exit door where the ground staff check your ticket and allow you out the airport building onto the 'stand' where the aircraft is parked. In the old days it was literally the gate leading onto the airport apron and the term has stuck.

Re: A TAAG Angola Airlines Boeing suffers damage from thrown tyre tread

What would cause the tyre tread to rip off like that? Aircraft tyres are re-capped, which means that they get new rubber bonded to the tyre carcass. Usually the number one suspect is under inflated tyre pressures and the first thing that you do when the aircraft arrives at the gate is to take that ...

The fact that the spoilers are raised and the flaps are deployed, shows that it is landing. By the way the spoilers will only auto deploy if the lever is lifted out of it's detent (armed). The puff of smoke from the nose gear (seen near the main gear) is an indicator as well.
