Hello there,
is it correct to assume that (737 classic):
In landing configuration at 30° flap setting, the slower she flies (closer to Vref+5) the higher ROD?
In other words, when hot'n'high, one configures for landing ASAP and then (e.g. Vref 125, Vapp 130) at 145 kt, the aircraft is positively aiming half-mile infront of threshold. Slowing down to Vapp involves pitch change that shifts the PAPIs down the FWD window. Is this not just an optical reference, will not slowing down yield a higher ROD?
Or perhaps the best wording to the question: In the example given is the a/c on the "left" side of drag/thrust curve and will slower speed thus provide for steeper approach angle, or not?
Thanks,
FD.
Post scriptum: Strictly VMC, 45%N1 and 141kt at 500', but you really did not want to ask, did you? :E :\
