If I leave the flaps at 0 degrees, slow down to 60 mph indicated and raise the

the aircraft is traveling.
I think the question here is "Above What?" If the aircraft is flying
then the relative wind will be coming from a direction in which the
velocity vector of the aircraft is pointing (assuming we are talking
still air).
But it will not be coming from "above the aircraft". A normal angle of
attack sufficient to satisfy the required lift vector must still exist.
The lift required when climbing is normally somewhat less than that
required in steady horizontal flight.
