We hover visually without any need for auto pilot. Our remit is to fly in accordance with CAA regs which states that there must be an appropriate level of visual cues to maintain a hover.
All that is required is a minimum SAS fit. The rest is eyeball. I occasionally glance at my GPS G/S but this doesnt indicate drift direction just movement over the ground.
We are not allowed to fly into 'dark areas' like Snowdonia or the Cumbrian hills et al.
Devon and Cornwall are fully functional NVIS, no trial anymore, Others are going operational as we speak. Within a few years most police units will be fully NVIS effective from take off to landing.
We have been flying NVG for the police observers for 7 years, because they are treated as passengers, there are no regs relating to their use. Pilots are the problem!!!!
VFR: How did you guess 750 feet at night???????????
