I hear you. Many times it happened that my Fo will call '' Speed'' when I fly raw data and the speed dropped by like 2/3kts getting slightly close to VLS and they will call me '' Speed!'
.. Lol. It drives me crazy, the call out is 5kts below VAPP not 2 or 3kts! I think people forgot what's the meaning of VLS... The way some guys panic, they must think VLS = Stall speed. xD.

I have no idea! Green dot speed I beleive? What I know is that getting below VLS is looking for trouble.
Edit times 10: I see, what I said is not really correct in my previous post but you understand what I mean: Slower, more drag then more thrust required to maintain VAPP... Or should I go back to the book? xD
I was referring to this graph page 5. From what I understand, a speed below VAPP and you are on the backside of the power curve.
