Goodness, and I thought the pommie way of writing rules was wordy, until I read that bit from SFAR73. Duplicatory in the extreme.
Interesting to note in today's mail a letter from Robinson which included Safety Notice 38, Practice Autorotations Cause Many Training Accidents.
Sub Para 1) "Rotor RPM in middle of green arc"
This from the manufacturer is incredible. There is instructions in the Maintenance Manual which describe where the RRPM should be under all load and DA conditions.
Usually, if the A/C is at MAUW it should be at the top of the Rotor Green arc , if the A/C is empty of fuel and with only a light pilot on board it should be at the bottom of the Rotor green arc. At the very least if the practice is being done with an instructor then SN-38 should have drawn reference to the RRPM position IAW with the MM Section 10-250 as checked in pre flight briefing.
To say again an adage form our ex chief pilot. "High auto RPM gives good RRPM prior to impact."
Anyone closer to the Robbie camp care to take on board a suggestion for an amendment to the SN?
cheers tet
