It takes a maximum of 3 months for a pilot to leave.
It can take 6-9months to recruit and train the replacement assuming no hiccups.
With a normal attrition rate(retirements/licence loss/moving on to pastures new etc) I am sure a cost is allowed for there.
Given that the attrition rate/replacement training requirements are now significantly higher I wonder what the true retraining costs are?
Numero Crunchero care to comment?
There is a message there somewhere
