Most US EMS units have LZ info/requirements on their website, but this information is frequently lacking in European operator websites. Wonder why?
And if Essex Police did produce a video, why did it not get some commercial sponsorship and it be distributed via the Home Office to all forces? Charging for safety information - go figure! Hmm, who would sue who for negligence....?
Yes, ultimately it is the pilot's decision whether/not to land, but people on the ground can make it so much easier if the information was readily available - eg I would hope all police/fire ground units have that training and have the checklist immediately available. All air units will obviously build up a lengthening list of pads they have used, so they can re-use when needed, but in the police/EMS world there will always be a demand where you don't have a site....
