SHORT FIELD TAKEOFF
What is a short field takeoff and how is it different from a normal takeoff?
A short field takeoff has three phases;
- Takeoff Roll
- Liftoff
- Initial Climb
We want a short ground roll, followed by an initial climb at Vx. This way, we use less of the runway and clear any obstacles (trees/buildings) at its end.
THE TAKEOFF ROLL
For the takeoff roll we make sure to configure our airplane by selecting the correct flap setting. For example, the Cessna C172S Skyhawk POH (Pilot Operating Handbook) recommends 10 degrees of flaps for short field takeoff. By adding the extra flap we increase lift.
“There’s nothing more useless than runway behind you.
We make sure to taxi so we have as much runway in front of us as reasonably possible. Once lined up and cleared for takeoff we apply brakes as we select takeoff power. Once engine parameters are confirmed normal — “T’s & P’s in the green” — release the brakes and start rolling forward.
THE LIFTOFF
As we approach Vr we gently pull back on the yoke to begin our liftoff at Vr. We then pitch to capture Vx and apply sufficient back pressure so as to keep our airplane from accelerating or decelerating.
THE INITIAL CLIMB
We continue climbing at Vx until we are clear of any obstacles beyond the end of the runway. We then pitch to capture our Vy speed. Finally we clean flaps and gear, and proceed with the after takeoff checklist.
Make sure to correct any common mistakes by doing the following:
- USE ALL OF THE AVAILABLE RUNWAY
- DON’T LIFT OFF TOO SOON
- ADD SUFFICIENT BACK PRESSURE TO MAINTAIN VX
You are the master of the aircraft, not the other way around.
- DON’T SINK WHEN PITCHING FROM VX TO VY
Pitch smoothly to avoid sink rate
