EXTRA 500 Description of Airplane and Systems
7.6 Nose Wheel Steering System
The nose wheel steering system consists of tappets on the nose
gear leg linked to the rudder pedals by a cable system and
springs. Landing gear retraction automatically disengages the
steering mechanism from the nose wheel and centers the nose
wheel for entry into the wheel well. The deflection angle of the
extended nose gear is limited to 30° to either side by
mechanical stops.
7.7 Ground Control
Ground control while taxiing is accomplished through the nose
wheel steering by using the rudder pedals; left rudder pedal to
steer left and right rudder pedal to steer right.
7.8 Taxiing And Ground Handling
Minimum turning radius is 20.8 m (68.2 ft) either with or
without brakes. A manual tow bar can be used to ground handle
the aircraft. While using a tow bar the minimum turning angle
applies also. See also section 2.
7.9 Flaps
The flaps are of the Fowler type. Each flap (two per side) is
attached to the rear wing spar and guided during its movement
by three wing tracks. Actuation is by means of two spindles,
which are connected to the central electrical flap motor by
flexible shafts. The flap motor is located in front of the rear spar
in the fuselage area of the wing and is controlled by the flap
position switch (refer to
Figure 7-4) in the cockpit. This switch
incorporates a preselect feature which allows the pilot to select
the amount of flap extension desired. When the
UP, 15° or 30°
position is selected, the flap motor is electrically actuated and
