Has anyone seen examples of an over-sized, over-extendable, cowl flap that also doubles as a speed brake?
As I was driving into work yesterday, it occurred to me that an oversized cowl-flap might work as a speed brake. Hinged at the front, the rear could have a linkage so it could be pushed down, normal to the direction of flight, to increase drag and steepen the approach. I was remembering a belly-board, speed brake seen on a Velocity. I tried a Google search but no hits, yet.
Speculation on my part, an over-extended, cowl flap might add some up-pitch to the plane. My thinking is to contact the owner(s) to see if they have any pilot reports on other flight characteristic and lessons learned about the cabin control and latching mechanism.
