The Haigh has a lever in the cockpit to lock/unlock the tailwheel.
When taking off, after aligning the aircraft with the centerline, the
lever is placed in the locked position and directional control is with
the rudders.
On approach to landing, the lever is checked to be in the locked
position. Landing roll is accomplished with the tailwheel in the locked
position and directional control is maintained with the rudder and
brakes. When the aircraft has slowed sufficiently is coming up on a
turn, the lever is placed in the unlocked position.
The Haigh tailwheel extends about 18inches aft of where the factory
tailwheel contacts the ground, creating a longer arm to improve
longitudinal stability.
