Leo De Vigne
The mention of Leo reminded me when he came out to the Bristow operation at Abu Dhabi to fly the Whirlwinds. In the course of several chats, I looked after the Whirlwinds there, he mentioned that if a Whirlwind was required to lift a heavy load we should adjust the RRPM to 220 (the lower limit) instead of the max 222 at which we normally set it.
