(b) Read the counts for each load sensor with WBC mode-22 and write the data in Figure 510, in the SENSOR COUNTS, SAMPLE 3 column.
M. Calculate Y (Wheel Weight Figures 503, 505, 507, and 509)
S 975-125
(1) Calculate the wheel weight averages for Figures 503, 505, 507, and
509:
(a)
Calculate the average of the three wheel weight samples for each wheel.
(b)
Write the results in the WHEEL WEIGHT, AVERAGE columns. (For the nose landing gear: Y = AVERAGE)
NOTE: AVERAGE = (SAMPLE 1 + SAMPLE 2 + SAMPLE 3) / 3
____
S 975-127
(2) For the main landing gear only, calculate the axle weights for Figures 505, 507, and 509:
(a)
Add the AVERAGE weights of the two wheels on each axle.
(b)
Write the results in the Y (AXLE WEIGHT) columns.
NOTE: For the main gear:
____ Y = AXLE WEIGHT = AVERAGE(outbd whl) + AVERAGE(inbd whl)
N. Calculate X (Sensor Counts Figures 504, 506, 508, and 510)
S 975-129
(1) Calculate the sensor counts averages for Figures 504, 506, 508, and
510:
(a)
Calculate the average of the three sensor counts samples for each sensor.
(b)
Write the results in the SENSOR COUNTS, AVERAGE columns.
S 975-063
(2) For the main landing gear only, calculate the axle counts for Figures 506, 508, and 510:
(a)
Add the AVERAGE counts of the two sensors on each axle.
(b)
Write the results in the AXLE COUNTS columns.
NOTE: For the main gear:
____ AXLE COUNTS = AVERAGE(outbd whl) + AVERAGE(inbd whl)
