1. General_______
A. This procedure contains a task to park the airplane in normal conditions.
TASK 10-11-01-602-001
2. Airplane Parking________________
A. General
(1) You must chock the airplane when it is is normally parked for short periods of time. As a minimum, put the chocks (four chocks per airplane) in front of and behind the inboard, or outboard wheels of a truck on each side of the airplane. The chocks can be positioned at the two trucks of the body gear or the two trucks of the wing gear with the parking brake off.
NOTE: The parking brake is not necessary when chocks are installed.
____ The parking brake is used to hold the airplane until the chocks are in position.
WARNING:_______MAKE SURE WHEEL CHOCKS ARE PROPERLY SET. IF WHEEL CHOCKS ARE NOT PROPERLY SET, THE PARKING BRAKE CAN BLEED DOWN OR BE INADVERTANTLY RELEASED. IF THE PARKING BRAKES RELEASES AND THE CHOCKS ARE NOT PROPERLY SET, THE AIRPLANE CAN MOVE WITHOUT WARNING. IF THE AIRPLANE MOVES INJURY TO PERSONS OR DAMAGE TO EQUIPMENT CAN OCCUR.
(2)
Static port covers are recommended when the airplane is parked for more than a standard turnaround.
(3)
Failure to remove covers from all pitot probes or coverings from all static ports before fight may cause large errors in airspeed-sensing and altitude-sensing signals, which may lead to loss of safe flight.
(4)
You can install covers on the vents, scoops and the other openings to keep the weather and unwanted material out. The steps for normal short time parking are given in this procedure. Use the procedure in AMM 10-11-02/201 for prolonged parking. Use the procedure in AMM 10-11-03/201 for parking in high wind conditions. When you park the airplane with the engines removed, the correct ballast is given in AMM 10-11-04/201. For special procedures to park the airplane for engine operation see AMM 71-00-00/201.
(5)
A static ground on the airplane is not necessary when the airplane is parked or is serviced during the turnaround operation. This does not include when the maintenance steps given below are done (AMM 20-41-01/201).
(a)
A static ground on the airplane is not necessary when you pressure refuel the airplane. An electrical bond between the airplane and the refuel vehicle is recommended.
