ABSTRACT:
A vertical stabilizer fin and rudder assembly for use on an aircraft including a stabilizer fin with airfoil surfaces and a rudder with a forward margin pivotally mounted on the trailing edge of the stabilizer fin. The assembly is subjected to Bernoulli forces as a relatively moving airstream passes over it in a chordal direction. A fin spoiler is pivotally mounted on each fin surface at a forward chordal location on the assembly whereby the effective sideslip capability for the fin surfaces, when the aircraft is operated in a crosswind, is substantially increased.
