We are not talking about an emergency diversion to an alternate, we are talking about the North Atlantic Contingency Manoeuvre, where the aim is to establish on a track offset by 15 miles. If you intend to establish on a reciprocal track then you have no alternative but to overshoot the track. However if you intend to establish on a parallel track in the same direction, then why overshoot it when it is not necessary. A turn though 60 degrees followed by 60 degrees the other way rolls out exactly on the 15 mile offset (I've tried it on the sim). Why insist on a 90 degree turn which overshoots the offset by some 13 miles?
