I don't really teach "turn 10, twist 10" either. I explain it since my student is bound to come across it but, even before I go go on, the student usually figures out that this s a lot more compleicated than it needs to be and that maintaining the target DME distance with small corrections (actually it is a bit like maintaining 0 GS) coupled with periodic twists of the OBS to maintain situational awareness is more than enough.
DME Arc - one of those maneuvers that, IMO, are much easier to fly than to explain. |
I agree. Unless I need to, I don't teach "turn 10, twist 10". I'd rather the student know where they are all the time and stay ahead of the plane. They can do that by knowing what radial they're on and where they're going. If they just know what side of the plane the navaid is going to be on prior to arcing, it's actually (for me and most students) easier than turn 10, twist 10.
...IMHO.
