7.7 Airplane control systems
Airplane control systems include control systems for drooping ailerons (flaperons), elevator
with trim tab, rudder and nose wheel, engine and brakes.
The control system is combined consisting of foot- and hand-actuated subsystems.
Ailerons and elevator are hand-actuated and are controlled using stick. The rudder and nose
wheel control is foot-actuated using pedals.
7.7.1 AMHT control system
The all-moving horizontal tail (AMHT) control system (see Fig. 4) is combined, it consists of
two 04.0 mm (5/32") cables, passing through a block of pulleys and a fairlead, rocker and
push rod.
"Push" and "pull" forces are applied by the pilot to the control stick (1) is passed via the
control column, pushrod (2) and bellcrank (3) to the cables (4). Then via the bellcrank (5)
located near the frame No.9, the control forces is passed to the pushrod (6) connected to
the AFHT arm (7). The cables routing is ensured with a block of pulleys (8), located in front
of the seat beam and fairlead (9) on the luggage container wall. The cable tesion and AFHT
incidence angle adjustment is ensured using the turnbuckles (10) located forward of the
bellcrank (5).
AMHT deflection angles: 15±1° up and 5±1° down.
