Short field Take off procedure
Short field take offs 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 take off differ from a normal one?
- What speed do we use after rotation to clear an obstacle?
