Each frame is going to need a return to service plan. It isn't just upload the new software, fill her up and off you go. These planes have been sat idle for months.

Re: Why did Luton Airport build its original terminal in that specific position?

I think Luton is a testimony into how a quart is just about squeezed into a pint pot. It was a municipally owned airport with little money for grand expansion plans - yet somehow they have grown it, piecemeal, into an effective functioning airport. The latest upgrades are the largest I have seen and...

A380 Slats

Just landed in Abu Dhabi and notice that all the A380’s are sitting at the gate with the slats extended.

I have not seen that on other types.

Is it just the A380?

As I, a fool I know, understand it - as the A320 is a FBW aeroplane the all fixes are software related and part of the core flight envelope programming.

The MAX however required additional and new flight control software to become initially certifiable. A big difference.
