📋 A–D Setup & Scale Configuration

A. Record weigh equipment on Step 5.L
B. Record calibration data in Table 6 (below)
C. Position scales per manufacturer manual & Figure 3.Use tire tracks / chalk marks. Wheels may be off‑center but must not touch frame.
D. Turn on platform scales, press MODE, set latitude/altitude, zero display.

⚙️ E–H CPU Box, Display, Oleo & Zero

E. Set up AC100 CPU box (N/A if not used).
F. Display control – use arrow keys to view cells/groups.
G. Measure oleo extension "A" for Weigh 1 (record in Table 10).
H. Zero each pad, verify zero display. Tare must be off scales or recorded.

📊 I. Weigh the Aircraft (First & Second)

I(1). Weigh brake rider – recorded above.
I(2)–(3). Tow aircraft onto scales, set parking brake, remove tow bar.
I(4). Measure & record pitch (Plumb bob) – enter below.
I(5). Read & record FIRST weights in Table 7.
I(6)–(8). Tow off, then back on for SECOND weigh.
I(9). Measure oleo extension "A" for Weigh 2 (Table 10).
I(10). Measure & record pitch for Weigh 2.
I(11). Record SECOND weigh data in Table 8.
I(12). Tow aircraft off pads.

Pitch – FIRST weigh

Pitch – SECOND weigh

Pitch ≤ 2° OK

Pitch must be < 2° ND or TD. If > 2°, re‑level.

✅ J–K Compare & Verify

J. Compare first & second weigh totals. % diff ≤ 0.25% required. If not, repeat with scale rotation.
K. Verification: second AMT must sign (above).
M. All data recorded. Weigh worksheet complete.
