Sorry, been away - excellent thread.
Going back to a comment on page 1 by ShyT concerning throttle position in turbine helis, I'm pleased to say that the layout in the Bell 205 (throttle on the collective) saved an oppo of mine in Oman in 1983. He was in the hover over an underslung load at Saiq (6,300 ft amsl, OAT 20 deg...) when the tail rotor decided it didn't want to play any more. He rolled the throttle shut, kept the aircraft level and cushioned the touchdown with no damage to aircraft, aircrew, ground hook-up party or even the load. Top stuff - proves that what's been written in this forum really works.
