TOWING OPERATION
Before and during aircraft towing the following safety precautions must be
observed.
Towing without an approved tow bar is prohibited. Alternative devices can
cause damage to the aircraft.
Before towing:
Make sure that down lock safety pins are correctly installed and that
all engine cowls are closed and latched.
Make sure that the fuel asymmetry is maximum 363 kg (800 lb).
Disengage the steering system with the switch installed on the control
yoke or set the external steering disengagement switch to the
"DISENGAGED" position and
Make sure that the green towing indication light illuminates.
During the towing operation, a technician must stay in the cockpit to set the
emergency/parking brake, if necessary.
When all towing precautions are preformed which are described in the AMM,
you can start the towing operation by the release of the emergency/parking
brake. Tow the aircraft slowly straight ahead before making a turn, and obey
the towing speed limitations, which are described in the AMM.
The maximum towing speed using a tow bar is 7 km/h (4 mph). You shall not
at any time exceed this speed.
After completing of the towing operation, tow the aircraft in a straight line for a
minimum of 3 meters (10 feet) or until the nose wheel steering system is in its
active range of ±76°.
