...AFTER they have PVR'd..
But After PVR and BEFORE termination, they are still in the RAF, and as such, still have their duties to perform, and if those duties include training and currency flights, then they are duty bound to perform them.
What would you prefer PA Ginger, people who have PVR'd just stopping work for the 12 months waiting time, drawing full normal pay, and sitting on their jacksies all day.
Get real.
