Wonder why they did that then? I'll tell you why, because they were flying outside of the limitations of the R44. They were that VMC 'on top', whatever that is, and the instructors semi auto (higher than usual rate of descent through clouds) resulting in low rotor rpm horn, and varying rpm can be heard, and what surprised me was that no-one mentioned one thing I noticed straight away.
Is the R44 certified for flight in icing conditions? The reason I ask is because there was snow on the ground, and they are above the cloud layer.
There is something wrong in this industry when instructors are showing low time ppl's/students, how to do this sort of thing.
