Airbrake system
Triple panel Schempp-Hirth type airbrakes are employed on the upper surface of
the wings. They open smoothly and are very effective, the change in trim is just
noticeable.
When unlocked, the airbrakes might get slightly sucked out by their spring loaded
cover strips, which, in this position, may then oscillate within their travel, causing
some rattling and/or banging.
This is immediately stopped by further extending or retracting the airbrakes.
The control of the aircraft is not affected.
With airbrakes extended, the indicated stalling speed is higher depending on mass
and C.G. position, see section 5.2.2.
A view of the airbrake system is found in the Ventus-3T Maintenance Manual.
