Key aviation formulas
| Flight Time | time = distance ÷ groundspeed + climb and taxi allowances |
|---|---|
| Wind Correction Angle | WCA = arcsin(crosswind ÷ TAS) · GS = TAS·cos(WCA) − headwind |
| True Airspeed | TAS ≈ IAS × (1 + 0.02 × density altitude in thousands of feet) |
| Fuel Burn | total = trip + reserve + contingency + taxi |
| Flight Fuel | total = trip + alternate + reserve + contingency + taxi |
| Rate of Climb | rate = altitude change ÷ time · gradient % = rate ÷ (GS × 101.27) × 100 |
| Descent Rate | rate = GS × 101.27 × tan(angle) · TOD = altitude ÷ 1000 × 3 nm |
| Density Altitude | DA ≈ pressure altitude + 120 × (OAT − ISA temperature) |
| Pressure Altitude | PA = field elevation + (1013.25 − QNH) × 27 ft per hPa |
