Whether a helicopter is suitable or not depends largely on the type of doors fitted. Shooting through the windows is a waste of time. Sliding doors are ideal, but car type doors (S76) or airstair doors ( S92 ) are a problem. All the non SAR Sikorsky S92’s in the North Sea have “airstair” doors – fold down with built in steps – which can’t be opened in flight. The ideal helicopter for flare photography has sliding doors and lots of power for hovering out of ground effect. The average flare is about 150 – 500ft AGL.
