Due to the high numbers pulled through onto PAS/FTC(A) there are insufficient Career Stream (CS) aviators to be promoted through to the higher echelons of a 2nd stage career (OF4/5 and beyond). The numbers volunteering are obviously due to the enhanced pension benefits of remaining at Sqn Ldr/Lt Cdr on the PAS/FTC(A) whilst those promoted beyond as CS aviators get less financial recompense for arguably greater responsibility and decision making. Therefore to encourage personnel to remain on the CS and redress the imbalance of the terminal financial benefits between the two, one workstrand that has a head of steam is to consider pensioning of flying pay for the CS aviator.
Obviously in the current climate of final salary pension schemes, credit squeeze etc the greatest challenge is undoubtedly going to be pushing it through the Treasury.
