paying for a TR has been around for decades
That doesn't make it right. Will paying for line training be an accepted practice in twenty years time? You only have to look at Ryanair to see where that has led, the way the management perceive the crew. O'Leary knows there'll always be someone prepared to undercut their 'colleagues'.
but paying for line training is wrong
Would you have said paying for a type rating was wrong twenty years ago? I suspect you would.
Its no good giving the chaps doing it a hard time;
Why not? They are undermining the rest of us just as those who first paid for their type ratings did.
How would you feel if you lost your job to someone who was
paying to fly? Because that's what's happening here. The next step is someone who passes the line training and buys another block of hours. Twenty more years down the road will that be acceptable?
