I did mean the highest TAS along with the lowest Cd, in the example posted at Vimd the IAS is 125 but if there min drag you will have xs power available I don't mean at a speed where
Pr = Pa
basically Vx =[Pa -
Pr] max and Vy = [THPa -THPa] max
the hump begins when the curve gets dragged down [the function for the THP is 1/2 rho SC[l,d] V^3] not the drag/thrust curve the THP curve specifically
We will not get best excess THP by flying at max TAS
agreed I did not word that too clearly
the hump occurs/begins when drag increases faster lift
I believe that you are an ex RAF fighter pilot
no, not at all ---
