7.7.2 AFHT anti-servo/trim tab control system
The AFHT anti-servo/trim tab is used for controlling the force on control yokes in pitch.
Fig. 5. AFHT anti-servo/trim tab control system
The AFHT anti-servo/trim tab control system (
) is combined, it consists of a lever (1),
two Ø1.5 mm (1/16 in) cables (2), a bellcrank (3), a friction clamp (9) and a rod (4).
The trim control lever (1) is located on the central console forward of the pilot seats and is
accessible for both pilots. The trim tab control lever is connected with cables (2) to the trim
tab control bellcrank (3). The cables are running through the flexible sheaths (6) in the
central console and a fairlead (7) located near frame No.9. The anti-servo/trim tab is
hinged at the trailing edge of the AFHT.
Tension of the cables and anti-servo/trim tab alignment can be ensured using the
adjustable forward stops of the sheaths (8), located aft of the seat beam. The trim control
lever friction force can be adjusted using the bolt (10) of the friction clamp (9), located on
the bellcrank axle (3).
The anti-servo/trim tab angles of deflection are: upward 7.4±1°, downward 7.6±1°.
