-
the total electrical resistance of the cable between the parking ground point and the grounding point on the landing gear must not be more than 500 milliohms.

 -
the resistance between the end connector on the ground cable and the nearest adjacent metal part of the landing gear must not be more than 10 milliohms.

 (1)
 Connect a ground cable to the aircraft grounding point on the landing gears. (Ref. Fig. 201/TASK 12-34-24-991-001, 202/TASK 12-34-24-991-002)

 (2)
 Connect a bonding cable between the fuel tanker and a grounding point on one of the MLG Legs or the NLG Leg, (Ref. Fig. 201/TASK 12-34-24-991-001, 202/TASK 12-34-24-991-002) or connect a bonding cable between the fuel tanker and the grounding point on the upper wing surface. (Ref. Fig. 203/TASK 12-34-24-991-003) The aircraft wheels must be on ground.

_________

R  Subtask 12-34-24-869-053 
R  A. Connection of the Ground Cables 
R  WARNING : ALWAYS CONNECT THE GROUND CABLE TO THE PARKING GROUND POINT_______ 
R  BEFORE YOU CONNECT IT TO THE AIRCRAFT. DO NOT ATTACH THE CABLE 
R  TO THE AIRCRAFT FIRST (THERE IS A RISK OF ELECTRIC SHOCK). 
R  NOTE : For the satisfactory removal of an electrical charge from the____ 
R  aircraft: 
R  - the aircraft ground cable must have a section of 22 mm2 (0.0033 
R  in2) or more. 
R  - the total electrical resistance of the cable between the parking 
R  ground point and the grounding point on the landing gear must 
R  not be more than 500 milliohms. 
R  - the resistance between the end connector on the ground cable and 
R  the nearest adjacent metal part of the landing gear must not be 
R  more than 10 milliohms. 
R  (1) Connect a ground cable to the aircraft grounding point on one of the 
R  MLG legs or the NLG leg, 
R  (Ref. Fig. 201/TASK 12-34-24-991-001, 202/TASK 12-34-24-991-002)
