Short Field take off

Short field Take-off

Short field takeoffs are utilized when it is necessary to get off the ground in the minimum distance and sometimes to climb relatively steeply to clear obstacles.

Objectives

  • How to take off on a short runway.
  • How to take off with an obstacle on your climb path.
  • How to get the best angle (vx) and best rate climb speed (vy).

Why?

  • A lot of runways require this technique.

Questions review

  • Demonstrate where to find and how to use the take off performance charts (POH)?
  • Explain what does Vx and Vy speed mean?
  • What are some factors that affect takeoff performance?
  • Why selected a ground reference point before rolling ?

Short field take off without obstacle

  • Cockpit check.
  • Flaps 10 or as recommended (check POH).
  • Brake apply.
  • Full power.
  • Release brake.
  • Lift off at minimum recommended flying speed (check poh).
  • Accelerate to Vy.
  • Retract flaps at safe height (AGL) and speed.

Short field take off with obstacle

  • Cockpit check.
  • Flaps/no flaps (check POH).
  • Brake apply.
  • Full power.
  • Release brake.
  • Lift off at minimum recommended flying speed (check poh).
  • Climb at Vx until clear the obstacle.
  • After the obtacle accelerate to Vy.
  • Retract flaps at safe height (AGL) and speed.

Review questions

  • Why should you hold the brakes until you achieve full power prior to beginning the takeoff roll ?
  • Where can we find specific information on short field landings?
  • How does a short field takeoff differ from a normal one?
  • What speed do we use after rotation to clear an obstacle?
