Fishboy, It's a sad fact that the police want pilots who can do the job done from day one and not pilots who have to think about what they are doing and how they are doing it with the aircraft. (I know what I mean!) The flying has to be instinctive and so must the emergency drills if anything goes wrong. "Lower Lever - Land" is ok for most singles but there are a hell of a lot of potentially complex emergency scenarios on something like a 135 or any other twin that the police use.
The reason there are so many military pilots in police aviation is purely because they have the experience and they are available! Once you have 500 hours twin (and 1500 hrs minimum) you might get the job but you will still be competing with the guy who has
A) Flown seriously low level and can map read and talk on the radio while he's doing it.
B) Fly close formation with another helicopter at night.
C) Flown with NVG.
D) By the very nature of his military experience will have demonstrated a high level of "Division of Attention" Captaincy and Capacity. In other words he can do lot's of things at once!
Every pilot is capable of these things but the military pilot has already done it and demonstrated that fact – which one would you choose?
I wish you luck all the same. Have you thought about contacting McAlpine Aviation Services and asking their advice on how best to get the experience you need?
