Thanks for that. I was on earlies this morning!
As I understand it, in order to conduct Performance Class 1 and Performance Class 2, helicopters must be certified to satisfy the Cat A criteria of Jar Ops3.480(a)(1). The S76A+ was certified as Group A under BCAR Sec G, which is acceptable under the the provisions of IEM OPS 3.480(a)(1)
As I remember the Sikorsky S76A+ flight manual refers to CDP for both Gp A take off and landing, whereas TDP clearly a Take off term. Maybe I would have been better off using TDP and LDP as generic terms.
The AW139 does perform to Class 1 at MTOW offshore, and it makes for a much less stressful departure. It is the way ahead
.
Whatever, the important part of the debate, as illustrated in your reply, is that you choose to wear a headset and some of your colleagues choose to wear helmets. Happiness!
Maybe we should all get opportunity to choose.
