My point is I’d rather be airborne
with speed in hand and altitude
beneath me
This gives me two energy options
to trade if I encounter windshear
I have some altitude to trade in case of
sink and some speed that can be
bled off in the escape maneuver
Building up excess speed past normal
VR on the runway only gives you one of these options and if the windshear is
strong enough you are still on the runway and have lost any additional energy gained
Youve lost any advantage, in fact you’re worse off than adhering to your normal VR
