How to fly a short-field takeoff: max runway, full power, V_X to clear, V_Y after

A short-field takeoff is the precision variant of the normal takeoff (A) — flown when the runway is short, an obstacle blocks the departure path, or both. The procedure is built around three ideas: use the full available runway so distance isn't wasted, apply full power before brake release so every foot of roll uses takeoff power, and climb at V_X (best angle of climb) until obstacles are cleared, then transition to V_Y.

V_X is the speed; obstacle clearance is the reason. If there's no obstacle to clear, V_Y is faster and uses less runway in total. V_X only earns its keep when there's something at the runway end.

Setup

  1. Complete the before-takeoff checklist; flaps per POH (typically 10°, sometimes 20° depending on the airplane).
  2. Position flight controls for the wind before entering the runway (same principle as A).
  3. Brief the obstacle mentally: how tall, how far. Confirm the published short-field distance from the POH for current conditions covers it.

Use the maximum runway

  1. Taxi to the very beginning of the runway — the threshold markings, not the runway-edge displaced markings if any.
  2. Align with the centerline at the threshold (V.E.S1).
  3. Hold the brakes firmly.

Full power before brake release

  1. Apply takeoff power with brakes still held (V.E.S2). Confirm full RPM and normal indications.
  2. Release the brakes only after confirming takeoff power and instruments are normal. This is the short-field distinctive — every foot of runway is rolling at takeoff power.
  3. Maintain centerline with rudder (right rudder for left-turning tendencies — same as A).

Rotation

  1. At the manufacturer's recommended short-field rotation speed (often the same as normal V_R, sometimes lower), apply back pressure to set the takeoff pitch attitude (V.E.S2).
  2. The airplane should fly off cleanly. Don't yank — over-rotation in a short-field takeoff costs both distance and altitude.

Climb at V_X until clear

  1. After liftoff, pitch for V_X (best angle of climb).
  2. Hold V_X through the obstacle clearance phase (V.E.S3). The airplane is climbing at the steepest angle it can sustain — the most altitude per unit of horizontal distance.
  3. The pitch attitude at V_X is higher than at V_Y. Verify by airspeed; the pitch picture alone can deceive.

Transition to V_Y after the obstacle

  1. After clearing the obstacle (or after a safe altitude if there's no obstacle), lower the nose to transition to V_Y.
  2. Continue climb at V_Y +10 / −5 KIAS through the remainder of the initial climb (V.E.S3) — same standard as the normal takeoff (A).
  3. Retract flaps per POH (typically once well past the obstacle and at a safe altitude).

Common pitfall: holding V_X too long. V_X is slower than V_Y — climbing at V_X for extended periods wastes the time and altitude that V_Y would gain. Transition as soon as the obstacle is cleared; don't hold V_X to the traffic pattern.
