■ MEASURED 实测 — FDR plot direct trace (NTSB Fig 11/13)
FDR-traced phase 14:20:38–14:20:59 (T+0..T+21s):
Pitch 俯仰: 0° → −35° smoothstep monotonic
Roll 滚转: 0° → −180° (T+11s) → −270° (T+20s)
Continuous left rotation; no oscillation
单方向左滚至右翼朝下，无振荡
Eng1/Eng2 Cutoff SW: simultaneous RUN→CUTOFF
AP-1/AP-2 Warn: ON ~3s after cutoff
Rudder 方向舵: untouched throughout 全程未动
FDR power loss ~26,000 ft FDR断电

■ ESTIMATED 估算值
Cruise 巡航: +2° AOA, wings level 机翼水平
Stable nominal attitude — no spline-derived jitter
稳定标称姿态，无样条切线抖动
Post-FDR 断电后 — 三轴统一从 3D 速度矢量推导:
Heading 航向 = atan2(tan.x, −tan.z) (spline track)
Pitch 俯仰 = asin(tan.y) + AOA(V/S)
Bank 倾斜 = −atan(v · ω / g), ω from Δtrack / 1.2s
Nose follows trajectory (no sideslip) 机头沿航迹（无侧滑）
Coordinated-turn relation 协调转弯公式
Aerodynamic rate limits 气动速率限制:
Pitch ≤25°/s (30°/s LOC), Roll ≤60°/s (75°/s LOC)
Hdg ≤4°/s cruise, ≤50°/s dive; ω cap 35°/s
G-load G载荷 — rough approx 粗略估算
