POH.4.5 Flight Control System

Question 1

Control Surfaces

Answer 1

Dual flight controls are installed in the Seneca II as standard equipment. The controls actuate the control surfaces through a cable system.

Question 2

Ailerons

Answer 2

ailerons are of the Frise type.

This design allows the leading edge of the aileron to extend further into the airstream to provide increased drag and improved roll control

The differential deflection of the ailerons tends to eliminate adverse yaw in turning maneuvers and to reduce the amount of coordination required in normal turns.

Question 3

Horizontal Stabilizer

Answer 3

horizontal tail surface (stabilator) is of the all movable slab type with an anti-servo tab mounted on the trailing edge. This tab. actuated by a control mounted on the console between the front seats, also acts as a longitudinal trim tab.

Question 4

Vertical Stabilizer

Answer 4

vertical tail is fitted with a rudder which incorporates a combination rudder trim and antiservo tab. The rudder trim control is located on the control console between the front seats.

Question 5

Flaps

Answer 5

The flaps are manually operated, aerodynamically balanced for light operating forces and spring loaded to return to the retracted position. A four-position flap control lever between the front seats adjusts the flaps for reduced landing speeds and a high degree of glide path control. The flaps have three extended positions - 10. 25 and 40 degrees - as well as the fully retracted position. A button on the end of the lever must be depressed before the control can be moved.

A past center lock incorporated in the actuating linkage holds the flap when it is in the retracted position so that it may be used as a step on the right side. Since the flap will not support a step load except in the fully retracted position, the flaps should be retracted when people are entering or leaving the airplane.
