Exceeding the upper limit can result in a loss of the main rotor-or cause big damages so "hitting the spot" is then the most minor of your problems..
An effective reading of the thread shall show the concept of having plenty of Rotor RPM at arrival during an EOL pertains directly to actual emergency landings and clearly suggested the real danger is arriving without ENOUGH Rotor RPM to safely land the aircraft.
Far more folks have been hurt....and helicopters destroyed by the lack of Main Rotor RPM than too much. If the aircraft is properly rigged there should be danger of causing one self any harm by an overspeed situation.
Again....I put forth my view on this.
Limitations are for Normal Operations!
There is absolutely no reason to worry about damaging an aircraft by overspeeding a rotor when you are about to crash it....the rotors are probably going to be trashed anyway and one might as well use them up saving yer hind end.
Yes.....the phrase "Ass, Tin, Ticket!" applies to this discussion on real life engine out landings.
Rabid has gotten some very good suggestions and the discussion branched out to a discussion on emergency landings....which cannot hurt anyone to read it. As in all things....pick the pretty berries and leave the bad ones.
