Guv and the advocates of No Seniority :-
The world without seniority already exists in aviation. You are refering to "Contract Pilots" - you know, the ones that you get from Park Aviation and the likes. The trouble is that although you have the flexibility of a quick "Hire and Fire"regime, you have to pay way over the odds for them. (i.e. a 6 month contract in Italy or the Far East on $10,000+ dollars per month + Housing allowances + Medical etc.)
Hence Huge salary bill !
That should surely help you to reduce the recruitment and training costs ? But wait, lets look a bit deeper into this rather short sighted idea. All your pilots are on short contracts - but they all need to be cleared to line, hence loads of training - hence loads more Training Captains, (which will diminish in number and become even more costly than ever). Oh, and then the new guys to type can't fly with each other for a while until they have done 50 hours or 50 sectors (or whatever). And once they are trained and have 6 months on line they get a better contract closer to home and leave the company. Oh dear, more recruitment, more training, more cost, less experience, more headaches...
Who, by the way is going to pay for all these type ratings, to work for a 6 month contract, Snow White ?
You would have to be INSANE to work in an environment like this.
Just look at what has happened in the IT industry. This is a prime example of what would happen in our industry if we went down that route. IT "consultants" can earn shed loads more cash than most pilots, they work 9 - 5 Monday to Friday and they don't get fatigue, shift changes at the last moment. In short they don't get there lives ******ed up like we do. Their employer doesn't have the power to rule their lives and free time like airlines can do, by producing late rosters, loads of changes, not agreeing leave until the last moment etc, etc....
Guv, as you well know, moving from one airline to another is not always simple (only in the boom years ). Additionally on your planet, it would be impossible for anyone to get promoted higher than an FO, as nobody would employ them as a Captain, as they :-
A) Have not been trained as a commander.
B) Have no command experience.
C) Have nobody to reccomend them in the new airline.
D) Can't get any of the above under your proposed system.
If everyone is responsible for their own type ratings, There may be trouble ahead...
