Same lift more drag!
Jamstab
Thanks for clarifying! We just went from A330 with frost on the Stab.
With a Vr at 150kts plus , to a C172 with that as a Vne.
Same same but different !
Turbulent air under a C172 wing due to frost is for sure not going to give you MORE lift.
What it will give you is some more drag! How much ? Quite a lot in some cases.
In this case I have to say, Laziness and madness!
