Ref Mashamba's experience: Interesting. I haven't done it in an NG, but I seem to remember moons ago, either B373 classic or B757, that if the CRS was wrong by an amount (unknown to me) the LOC would not be captured and the a/c would fly through the C.Line. Help me refresh.
Next week I'll try it somewhere and report back, unless FDMS is looking over my shoulder.
