AIRPLANE WEIGHING PROCEDURES (Continued)
2. Leveling:
A. Place scales under each wheel (minimum scale capacity, 2000
pounds nose, 4000 pounds each main). The main landing
gear must be supported by stands, blocks, etc., on the main
gear scales to a position at least four (4) inches higher than
the nose gear as it rests on an appropriate scale. This initial
elevated
oosition will com~ensate for the difference in
waterllne stat~on between the'maln and nose gear so that f nal
levellng can be accomplished solely by deflating tne nose gear
tlrp
-.
B. Deflate the nose tire to properly center the bubble in the level
(see Figure 6-1). Since the nose gear strut contains an oil
snubber for shock absorption rather than an
airloil strut, it can
not be deflated to aid in airplane leveling.
3. Weighing:
A. Weigh airplane in a closed hangar to avoid errors caused by
air currents.
B. With the airplane level and brakes released, record the weight
shown on each scale. Deduct the tare from each reading.
4. Measuring:
A. Obtain measurement A by measuring horizontally (along
airplane centerline) from a line stretched between the main
wheel centers to a plumb bob dropped from the center of the
nose jack point located below the
firewall and housed within
the nose strut fairing.
B. Obtain measurement B by measuring horizontally and parallel
to the airplane centerline, from center of nose wheel axle, left
side, to a plumb bob dropped from the line between the main
I
wheel centers. Repeat on right side and calculate the average
of the measurements.
5. Using weights from step
3 and measurements from step 4, the
airplane weight and C.G. can be determined.
6. Basic empty weight may be determined by completing Figure
6-1.
