I see HT knows it all
UK, ex AAC, says it all. UK CAA srg document Airworthiness Flight Test Report, S76B...... Single Engine Climb Performance..... establish a climb at Vbroc......
.....Sikorsky S92 VIP Brochure (maybe written by Nick Lappos? 'making up an incorrect term') performance section refers to climb at Vbroc
Most professional pilots know this, don't they?
