2. Jacking and Levelling

NOTE:

The following procedures assumes that a conventional aircraft weighing kit

utilising three individual electronic load cells is used to weigh the aircraft either

on jacks or on the aircraft wheels. If such a system is not available appropriate

variations to the procedures will be required.

WEIGHING ON JACKS

(a) Place the main jacks under the jacking points located on the front wing spar just outboard

of each strut;

(b) Place a suitable xture through the tail’s tie-down point;

jacks can then be adjusted to nally level the aircraft.

CAUTION:

PREFERENCE SHOULD BE GIVEN TO RAISING THE WINGS BEFORE THE

TAIL AND LOWERING THE TAIL BEFORE THE WINGS.

WEIGHING ON WHEELS

(a) Using suitable ramps, roll the aircraft onto load cell platforms, afterwards ensuring there

is a small amount of clearance between each ramp and load cell to prevent interference

from ramps on load cell readings;

(b) Park brake is to remain disengaged during load cell readings;

maximum tire pressure limitations and ensuring that after weighing is completed that nose

wheel pressure is restored to suit operational requirements;

(d) If levelling cannot be achieved by adjustment of tire pressures alone, shim underneath the

load cell platform feet, ensuring that the platforms are steady and level.

NOTE:

The aircraft will be longitudinally level when the two marked level points on the left

hand side of the fuselage are at the same elevation. This can be determined by

using a water level.

Alternatively a suitable spirit level may be used over the top surface of the seat

attach ttings on the cabin oor. Both longitudinal and lateral levels may be

determined this way. The aircraft should be laterally levelled as far as practically

possible.
