SAR Helicopters
Hello,
I'm not actually involved in the aviation business but have a interest in the mechanics of heli's and I was hoping for some information. I'm a keen watcher of the Highland Emergency program and frequently they seem to be unable to maintain a hover to winch due to a lack of power, an alarm is heard going off and the pilots quoting power over 100%. In my limited knowledge of helicopter flight characteristics i'm assumming this is as most of the power is going into keeping the heli steady in the wind and theirs not enough to maintain the height or is it the other way around in that the wind actually helps and a drop in wind can be the problem?
Thanks,
Dave.
