I used to teach procedural IF in my last job, so I have been higher than the cloud base. In answer:
Currency: 3 approaches for 4 pilots costs money. Who pays?
Fuel Reserves: Our 135 with 3 crew and all the kit has an endurance of approx 90 mins. We can plan all we want, but MAUW is MAUW.
SPIFR: We dinosaurs DO use the autopilot... It's better than us.
NVG for some units would move police aviation forward. I personally would love an IR, but if I was the UEO I wouldn't spend the precious cash.
