Folks,
For remembering the sector entries, I like the "Three Bears" method.
Daddy Bear is the big bear, he goes straight in.
Mummy Bear goes over on her back.
Baby Bear is under 30.
With fond memories of the late Jock Roberts, Officer, Gentleman and former QF link thro' to simulator instructor, who thought this up when we moved from four sector entries, to the new fangled three sector. Longer ago than I really want to remember, even before political correctness.
It's worked for me for a long time, long before details were printed on charts. No numbers, no names, just an easy mental picture.
Tootle pip!!
