Qatari515,
otherwise I dont see the reason for hiring ab initio pilots right!
Hiring ab-initio pilots is encouraged by the government under the Qatarisation master-plan and the targets are something like ~40 qataris per year both crew and engineers to be trained. Even though the plan mainly focuses on the hydrocarbon sector it is still encouraged and supported through the government and the Ministry of Education in other sectors such as aviation.
Recently the airline recieved a grant for training and QAC will be expanded and should soon have 2 intakes of students every year in order to increase training capacity.
Even if at some point in the future they have all the pilots they need, and still get a lot of foreigners applying the locals will still be hired. In the unlikely even that there are more Qatari Ab-initio graduates than there are positions to fill they will take the place of expat crew. That will probably not happen because there are not enough people in a country where even the Air Force hires expats to fly their aircraft! There will always be a need for expats to help keep the country running smoothly.
