Good news is you get to practice a stall recovery and a touch and go in one approach.
You are right buddy. It was late and i screwed up on simple math but actually there was no stall since IAS was safe in spite of incorrect math. But no matter. The principle is flawless despite my maths in the above being pre-primary level!
should have said fly approach at GS 80 = IAS 100
downwind maybe fly GS 140=IAS 120
point is it works.
Now someone mentioned pitch /power which is paramount as a starting point. Agreed 737 it’s 6pitch/60N1
But do need your weight too.
Amd on the approach your pitch power change due to headwinds. But you don’t know by how much do you !
GS solves this
