B. Prepare to Taxi the Airplane
S 582-002
(1) To prepare to taxi the airplane, you must do the steps that follow:
NOTE: These steps are only minimum procedures.
____
(a)
Use the airline taxi checklist.
(b)
Examine the external areas of the airplane.
(c)
Make sure that the wheel chocks are in the correct position.
(d)
Make sure that all engine cowls, doors, and hatches are closed or put into a satisfactory position.
(e)
Make sure that the engine inlets and exhausts are clear.
(f)
Make sure that the flight control surfaces are clear and will not touch the ground equipment.
(g)
Make sure that the tires are in a satisfactory condition.
CAUTION: DO NOT TAXI THE AIRPLANE WITH THE SHOCK STRUTS OF THE MAIN
_______ LANDING GEAR FULLY COMPRESSED. DAMAGE TO THE SHOCK STRUTS CAN OCCUR.
(h) Make sure that the shock struts of the main landing gear are filled correctly (Ref 12-15-31/301).
CAUTION: DO NOT TAXI THE AIRPLANE WITH THE SHOCK STRUT OF THE NOSE
_______ LANDING GEAR FULLY COMPRESSED. DAMAGE TO THE SHOCK STRUT CAN OCCUR.
(i) Make sure that the shock strut of the nose landing gear is filled correctly (Ref 12-15-41/301).
CAUTION: DO NOT LET THE SHOCK STRUT OF THE NOSE LANDING GEAR EXTEND
_______ MORE THAN THE MAXIMUM PERMITTED EXTENSION OF 10 INCHES. AN EXTENSION MORE THAN 10 INCHES CAN CAUSE THE CENTERING CAM TO ENGAGE AND CAUSE DAMAGE TO THE SHOCK STRUT DURING A TURN.
IT CAN ALSO MAKE THE AFT CENTER OF GRAVITY LIMITS CHANGE AND CAUSE THE AIRPLANE TO ROTATE ON TO ITS TAIL.
(j)
Make sure that not more than 10 inches of chrome surface, of the inner cylinder on the shock strut, shows.
(k)
Make sure that the towing lever on the nose landing gear is in the NORMAL position (Ref 09-11-00/201).

(l)
Make sure the flight compartment seats are adjusted as follows: 1) To give the correct view from the flight compartment windows.
2) To give the correct position to operate the rudder and brake pedals.
(m)
Make sure that all airplane systems are prepared to have electrical power safely put on the airplane.
(n)
Supply electrical power (Ref 24-22-00/201).
CAUTION: A MINIMUM OF 1675 POUNDS (760 KILOGRAMS) OF FUEL IS
_______ NECESSARY IN NO. 1 AND 2 FUEL TANKS TO GIVE COOLING TO THE HYDRAULIC FLUID. WHEN SUFFICIENT FUEL IS NOT IN THE FUEL TANKS, THE HYDRAULIC FLUID WILL BECOME TOO HOT.
(o) Make sure that the fuel quantity indicator on the center instrument panel, P-2, shows a minimum of 1675 pounds (760 kilograms) of fuel.
NOTE: Add the quantity of fuel that will be necessary for the
____
engine start and taxi operations.
(p) Make sure that the hydraulic systems are pressurized for the brake and nose wheel steering operations (Ref 29-15-00/201).
NOTE: Hydraulic power for the brakes comes from hydraulic
____ system B. Hydraulic system A gives automatic backup when system B does not operate. If all hydraulic systems do not operate, the airplane must not be taxied. But, if all hydraulic systems stop during the taxi, the brakes will be operated through the brake accumulator.
When it is fully serviceable, the brake accumulator will permit the brakes to be applied approximately 8 to 10 times.
The nose wheel steering gets power from the hydraulic System A. Backup power for steering comes from Hydraulic System B. The landing gear control lever must be in the DN position to use the nose wheel steering system.
(q)
Make sure that the landing gear control lever is in the DN position.
