S61 at Humberside, offshore engine failure!

Sorry Navy Torque for stealing your post

Crab,

I did admit without reservation in my reply to Aser that I was wrong in my highlighted statement which incorrectly asserts that there is no exposure in the event of the remaining engine failing. I admitted it was

Absolute Crap.

I did say single engine H/V curve twice - I will say it a third time - the H/V graph in the Bell Flight Manual is titled: -

"Height velocity diagram (OEI)"

I think that a One Engine Inoperative H/V diagram and a single engine H/V diagram are one and the same for a machine with 2 engines!

Strangely enough I don't refute your high level transit part at all (basic airmanship) and if (a HUGE IF) we were given sufficient time (and Company and Client) permission to hone our autorotative skills to the point where we could guarantee a "greaser" every single landing I would agree with that your suggestion would reduce exposure even further than our existing profile.
The latter is unfortunately never going to happen - I am painfully aware when carrying out recurrency check and training on both the Sim and the helicopter of general poor skill levels of otherwise excellent medium to large twin drivers when it comes to autorotations.
We have the facilities and requirement for our 206L4 & 407 offshore pilots in Nigeria and the GOM to carry out full engine offs to the water during annual recurrency training in Louisiana - We use a Bell 206 on fixed floats. This is excellent value and after a couple of days, a 180 degree engine off auto from 80 knots and 400 feet downwind becomes a routine event. I would love all Crews to attend this training annually but the perceived safety of the twin and the cost of providing this training precludes this in the so called "Real World" that we operate in.

Once again - our standard laid down Class One profiles are designed to keep us out of the OEI/Single Engine H/V curve at all times to minimise exposure. If we can't achieve this we are flying a Class Two profile which may place us in the H/V curve for short periods - e.g. Operating to a confined area or post commital point to an offshore platform.

Apologies for my rudeness but maybe you have been told once in a while that you can be exasperating.
