Whats difficult with any of this.
Probably not much if the training requirements are the same as they are for the Police.
Stage 1 training qualifies to fly not below 500'. Consists of approx 1.5 hour groundschool, 3 x 1 hour flying sorties, plus a line check.
After 25 hours flying at Stage 1, Stage 2, operations to ground level training: approx 1 hour groundschool, 2 x 1 hour flying sorties, plus line check.
Edit: Numbers are now correct.
