Associated conditions (POH)

  • Paved dry runway; full power before brake release; gear down; flaps 10°
  • Humidity >80% RH can add up to ~10% to takeoff distance (not auto-applied)
  • Speed schedule: 77/84 @3368 · 72/80 @3100 · 69/78 @2900 · 65/75 @2700 KIAS (TO / 50′)
  • Wind from chart headwind/tailwind fans; runway gradient assumed 0% (no gradient input)

POH notes (Sec V 5-23 / 5-24)

  • Note 1: Above 22,000 ft, power settings >2300 RPM → operate at 1675°F TIT or richer.
  • Note 2: Above 30.5 inHg MP → FULL RICH mixture only.
  • Note 3–4: Decrease FF 0.5 gph per 10°C above std; increase 0.5 gph per 10°C below std.
  • Some low power settings may not be attainable (low CHT/oil temp).
  • TAS / range / endurance charts are not included — still graphic in Sec V.
