  1. 第二章 民用航空器 第七节 飞行性能

  2. 起飞速度

  3. VREF 1,23 VSR VMCL 着陆 • Means of braking : • wheel brakes • Spoilers • Reverses VREF 50 ft V=0 braking LD

  4. 飞行剖面与油量 Holding En route reserve Trip fuel Alternate fuel Taxi fuel PROC Parking Go around Brakes release Touchdown DEP Alternate DEST

  5. 各种重量关系 • 最大起飞重量（MTOW） • 最大着陆重量（MLW） • 最大无燃油重量（MZFW） • 使用空机重量（OEW/DOW） • 业载（Payload） • 燃油重量

  6. 最大业载的计算 • Maximum weights • Maximum structural take-off weight: MTOW • Maximum structural landing weight: MLW • Maximum zero fuel weight: MZFW • Capacities • Cabin capacity • Cargo capacity • Tanks capacity

  7. 最大业载的计算 • tow = dow + payload + fuel ≤MTOW • lw= dow+ payload + fuel - trip fuel ≤MLW • zfw = dow + payload ≤MZFW • trip fuel + reserves + taxi fuel ≤Tanks capacity

  8. 最大业载的计算 • Payload ≤ (MTOW - dow - AF - HF) - (TF + RR) Payload Range

  9. 最大业载的计算 • Payload ≤ (MTOW - dow - AF - HF) - (TF + RR) • Payload≤ (MLW - dow - AF - HF) - RR Payload Range

  10. 最大业载的计算 • Payload ≤ (MTOW - dow - AF - HF) - (TF + RR) • Payload≤ (MLW - dow - AF - HF) - RR • Payload≤ (MZFW - dow) Payload Range

  11. 最大业载的计算 • Payload ≤(MTOW - dow - AF - HF) - (TF + RR) • Payload≤ (MLW - dow - AF - HF) - RR • Payload ≤ (MZFW - dow) • Trip fuel + reserves ≤ tanks capacity - taxi fuel Payload Range

  12. 最大业载的计算 • Payload ≤ (MTOW - dow - AF - HF) - (TF + RR) • Payload≤ (MLW - dow - AF - HF) - RR • Payload ≤ (MZFW - dow) • Trip fuel + reserves ≤ tanks capacity - taxi fuel Payload Payload Allowed payload Range Range
