I am very pleased to hear that some of you found the HCGB article useful, this was my sole intention and I hope it has given a small in site into why some of these dreadful events happen. As it happens I am in the process of writing another article on my views on the lost skill of manual throttle skills which can lead to Low RPM Rotor Stall and the subsequent loss of 'main rotor control' and possibly 'main rotor divergence'. We seem to have forgotten that the pilot is the 'primary governor' and not the aircraft's engine governor.
I did get your e-mail 212man, I will take you up on your kind offer at some point, I am in the MAS lounge at the moment on my way to Bangladesh to conduct some R66 training.
Thanks to all for the positive comments, it is easy to shoot the messenger.
Keep your RPM in the green.
Regards
