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 fixture through the tail’s tie-down point;
(c) Raise all three jacks at a similar rate until the wheels are clear of the ground. Individual
jacks can then be adjusted to finally 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;
(c) Adjust the nose or main wheel tire pressures as required to level the aircraft, observing
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 fittings on the cabin floor. Both longitudinal and lateral levels may be
determined this way. The aircraft should be laterally levelled as far as practically
possible.
