Rotorcraft Flying Menu >Helicopter
Flight Controls > Antitorque Pedals
The antitorque pedals, located on the cabin
floor by the pilot’s feet, control the pitch, and therefore
the thrust, of the tail rotor blades. [Figure 4-5] . The main
purpose of the tail rotor is to counteract the torque effect
of the main rotor. Since torque varies with changes in power,
the tail rotor thrust must also be varied. The pedals are connected
to the pitch change mechanism on the tail rotor gearbox and
allow the pitch angle on the tail rotor blades to be increased
or decreased.
Figure 4-5. Antitorque pedals compensate
for changes in torque and control heading in a hover.
