What are all of the long haul crews doing now? eg, 380 captains and FOs and the B787 lot? Have they retired? If so, will a year be long enough to rehire or to recruit new pilots and to get them up to speed (no pun intended...)?
Assuming the 380s come back....
There were approximately 100 A380 Captains. From what I can tell, 59 of them took the VR package, and about 25% of them were from the training side. So, you probably have enough people left to have a mini training department, and to run about 4-5 aircraft. Each of of these people is going to require a solid 3-4 months of training, with line sectors obviously being almost impossible to find. Basically this would be every bit as complex as introducing the type in the first place. I have no idea what CASA would mandate, and I expect they don't yet know either.
The sims alone would take about 12-15 rides. You'll get 4 sessions per day if you're lucky, and you can't really schedule them for each person closer than one every two days. So that means it would take 30 days per person. Staggering that a bit has the effect of giving you two Captains out of the pipe each week, and an FO along with each as a bonus. So, to get back to 100, it would take an initial 3 months, then at 2 per week you'd have the full lot about 50 weeks later. So, a bit over a year...
It's gone on for so long now that it's not really a refresher for anyone, so there wouldn't be much difference between refreshing your exist Captains, or training new ones from the other types.
Pretty well all of the remaining 380 people are currently just stood down, in limbo. The company has not been doing any ongoing training with them. From what I gather, many see the way the company is using stand-down as a way of avoiding their redundancy obligations. People are doing what they can. It's very sad, and quite disgusting to see a particular CEO still being paid millions.
I'm guessing that the A380 is now consigned to history, which, if this is the case, then that's sad. It was the best 'plane that I travelled in, comfort and noise-wise.
It was made for a niche that wasn't quite as bit as Airbus envisioned, but it's a very sad ending for a wonderful machine. I have much more time for it than I do for any of Boeing's current offerings, and, having flown both, I'd rank it above the much loved 747.
