How many white out landings has the crashed pilot done in his career?
How many white out landings has he practiced in the 12/6 months before this accident?
More than the average (international) lowland helicopterpilot have under the belt. Snow happens not so much in the flat european areas. Some years ago i was in february in south england and surprisingly the whole area was white and in deep snow. Watching the flight ops i was sure the mass of helicopterpilots never operated in really snowy conditions. May be not so much lowland civil or police operators does special training for the pilots for the some days of snow per winter.
Sure you can't compare a snow proven highland pilot with a lowlander. But be sure the high time federal police pilots are trained above the average lowlander and all of the involved pilots have done a lot of hours also in snowy conditions as HEMS pilot and on border guard missions in mountain areas.
This only shows us that accidents happen-no matter how much experience a pilot got..
Thats the point. Such (human errors) accidents are only to prevent with stopping all helicopter ops because there will be allways a clever one finger pointing to not enough experience in snow, in gusts, in rain, in bad visibility, in tight landing places, in max take off weights - to make it short, in helicopter usual ops with allways changing conditions.
