V Speeds on the Drag Curve

[Microburst2002]

The fast-slow indicator information comes from AoA directly. No matter what the weight is. But I don't know if it varies with configuration or it is for landing configuration only. I the latter case, it is not valid for an all eng out glide from cruising level.

Thanks EGh

I used to call that the reverse command region (Naval Aviator, I guess)
It is funny how, if you add just al little thrust when speed decays a few knots below target VAPP it won't suffice. It keeps slowing down, so you add a little more thurst. And you can be doing that until you have max climb! That is the back side of the curve. And sometimes actual GW is heavier than the one calculated by the loadsheet, and then you are deeper in the backside. However, usually acutal GW is, more often than not, lighter. The Fast-Slow indicator is a hint, in that case.
Another factor to take into account is the VREF additives for wind component, so you will usually fly somewhat faster than the neutral point iln the fast-slow scale.
