7.7.2 AMHT antiservo/trim tab control system
The AMHT antiservo/trim tab is used for controlling the force on control yokes in pitch.
Fig. 5 AMHT antiservo/trim tab control system
The AMHT antiservo/trim tab control system (
) is combined, it consists of a lever (1),
two
Ø1.5 mm (1/16 in) cables (2), a rocker (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 rocker (3). The cables are running through the flexible sheaths (6) in the central
console and a fairlead (7) located near frame No.9. The antiservo/trim tab is hinged at the
trailing edge of the AMHT.
Tension of the cables and antiservo/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 rocker axle
(3).
