I was wondering if with the weather model in SOW, that we most likely will encounter simular stall condition's as that decribed below. It would seem to me, that we will most likely see this in game. This will most certainly add another thing that we must keep our eyes on. But I think that it will be a good thing to have, if only for the realism of the fm.


Downwind stall:
For instance, a powered plane flying north with airspeed of 30 knots against a
30 knots headwind has zero ground speed.
If you turn 90 deg. left (west), the plane's airspeed still is 30 knots but is now
drifting 30 knots to the south resulting in 42 knots ground speed to the southwest.
If the plane keeps turning south, the drift due to the wind is still 30 knots but now
the ground speed becomes 30+30 = 60 knots, while the airspeed still is 30 knots.

The pilot on the ground will see the ground speed but not the airspeed, and since
the plane seems to move much faster flying downwind, the pilot may instinctively
slow down the plane below the stall speed.
This results in a pilot-induced stall due to the optical illusion of the plane's higher
ground speed when flying downwind
