I slow to respond, but are you chaps talking about the same thing?
 
There is a leading edge slot that goes the full length of the leading edge, which is used to allow air to transfer from the bottom to energize the upper air flow at high angles of attack (as in landing configuration), used in many STOL light aircraft.
 
I think dl is talking about a slot (from front to back -not the full distance I assume), parallel to and close to the fuselage. Don't know what that could be used for! But would like to know!

----- I think that was for slow flight, there was a production aircraft the had a slot through the wing but was always open and i heard that you did not want to close it off, the plane became almost uncontrolable at low speed. FWIW

Last year I was on the aircraft carrier Midway at San Diego and at the tail they had an old North American RA5C.  As I checked it out a discovered that it had a slot in both wings just inboard from the wing fold that allowed air to move from the top of the wing to the bottom...presumably in a landing configuration.  Does anyone by chance know why it was needed or when used?
 
Thanks.

Start the year off right. Easy ways to stay in shape in the new year.
