Folks,
I have used the "Three Bears" method since I was on the DC-3 --- which is when we changed from the 4 sector entry.
Think about/visulaise the three sectors;
the "big" sector, represents Daddy Bear, and;
the next sector, smaller, is Mummy Bear, and;
the smallest sector is Baby Bear, then;
Daddy Bear goes straight in, Mummy Bear lies on her back, and Baby Bear is "under 30".
Works for me, and every other pilot who did their Link for an initial instrument rating with a remarkable instructor, no longer with us, Jock Roberts, ex-RAF and long time Qantas in the good old days.
Tootle pip!!
