Handysnaks says : We would still need an exemtion from rule 5 and I feel sure it would only be issued for twin engine aircraft.
Why ? The latest HiDef cameras with long lenses, superscopes and IR can deliver their best work from 1500ft. What reason is there to go lower ?
The latest cameras are exceptionally good. The exemptions are needed for when the cloudbase precludes us from operating as high as 1500 ft!
