As one pruner has already stated I would be wary about investing monies in this as within the UK there are very few openings for FD. If you look on the CAA web you may also findf that the FD will dissapear to be replaced by a FDM (flight dispatch manager) as the the CAA audits have identified a flaw in the present system that no-one has responsibility in and around the a/c with the current FD spending more time at the boarding gates. As a 'duty of care' under UK & EU laws an FDM will eventually undertake this role with responsibility, accountability and skills to manager the staff & agencies in and around the aircraft.
