On the blade sail point, my understanding is that main blades are most dangerous when moving slowly, ie: at the beginning of the engine start procedure, and at the end of the shutdown. Main blades on all types get the bulk of their rigidity from centrifugal force, and are therefore less likely to sail out of the normal plane of rotation as rotational speed increases. Yes, people?
Maybe someone has seen written advice on this point in any civil/military handling or POH manuals?
For my part, it was always drummed into me during my early days about the dangers the main blades represent. The 'thumbs up/eye-contact-with-the-pilot' rule was perhaps the first lesson I learned.
Anyone else receive similar instruction?
