-
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 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)
