Check against max ZFW (for B738, typically 62,732 kg) → OK. Trip fuel + Contingency + Alternate + Final reserve + Taxi. Example: 7,200 kg (including taxi fuel). Step 5 – Takeoff Weight (TOW) TOW = ZFW + Fuel load = 51,436 + 7,200 = 58,636 kg
From Weight & Balance graph (CG envelope – B738), Index 44.3 at TOW 58,636 kg gives (within limits: 13–32% MAC typical for takeoff). Step 7 – Stabilizer Trim Setting Using TOW & CG % MAC, read trim units from flight crew operating manual (FCOM) – e.g., 4.8 units ANU (Aft Nose Up) . Step 8 – Landing Weight (LW) LW = TOW – Trip fuel = 58,636 – 6,500 = 52,136 kg
