− Tow the airplane slowly straight ahead before turning. Complete
the airplane towing in a straight line for a minimum of 3 m (10 ft) in
order to align the steering as close as possible to the 0º position.
NOTE: Do not stop the airplane when turning if it is not necessary.
CAUTION:
• DO NOT OVERSTEER. THE MAXIMUM TOWING
ANGLE IS 170º TO THE RIGHT AND 170º TO THE
LEFT. IF THE MAXIMUM TOWING ANGLE IS
EXCEEDED DAMAGE TO THE NOSE LANDING GEAR
CAN OCCUR. TAKEOFF IS NOT ALLOWED WITH
DAMAGED NOSE LANDING GEAR.
• DO NOT APPLY THE AIRPLANE BRAKES DURING
THE TOWING PROCEDURE. REGARDLESS OF THE
SPEED. USING BRAKES CAN CAUSE DAMAGE TO
THE AIRPLANE STRUCTURE AND/OR TO THE NOSE
LANDING GEAR. ONLY WHEN THERE IS A RISK OF
COLLISION OR DAMAGE TO THE AIRPLANE AND IN
ACCORDANCE TO THE TRACTOR OPERATOR, USE
THE AIRPLANE BRAKES TO STOP THE AIRPLANE.
After towing operation is finished:
− Apply the emergency/parking brake or install the wheel chocks, as
required.
NOTE: If hydraulic systems 1 and 2 are pressurized, always apply
brakes with the pedals before pulling and releasing the
emergency/parking brake handle to prevent hydraulic fluid
transference from system 1 to system 2 or vice versa.
− Make sure that nose wheel displacements are below the maximum
operational limit.
NOTE: Steering handle actuation with nose wheels beyond their
operational limits may cause damage to the nose wheel
steering system.
