A320NEO lower Vapp in CONF FULL

[FlightDetent]

I hear you. Also the holding speed for IAE is GD+20 as opposed to CFM, and the GD ceilings are vastly different as you pointed out previously.

For the clarity of at least one of the topics running, I chose to strictly talk only about IAE vs. neoPW, both sharkletted.

GD is higher. Vmca is higher. Vref F3 is higher.
Vref f=40° is less by 6 kt, and thus is limited at low weights by Vmcl, which is also higer.

For A320 family VLS= k×Vs1g with 1.23= <k=<1.28
VLS=>VMCL
F Conf3=k×Vs1g conf3 with 1.32=<k=<1.36

The only suspect left is Vs1g. Back to post #13.
