Short-Field Takeoff and Maximum Performance Climb
A short-field takeoff gets the airplane off in the least distance and over an obstacle with the steepest climb.
Every foot of runway, full power before brake release, and precise speeds: rotation speed, then VX over the obstacle, then VY.
Why this one matters
A short runway with obstacles leaves no margin for a weak engine, a heavy airplane, a hot day or poor technique. Accidents here come from pilots who didn’t run the numbers, pulled up before flying speed, or stalled at VX trying to clear trees. Planning and precise speed control are what make the takeoff work.
Can’t miss
- •Start at the very beginning of the runway, so you use all the takeoff distance available.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
- •On a firm, clean surface, hold the brakes, set full power and check the engine before releasing them; check the engine and flight instruments again before rotation. On gravel, dirt, grass or a contaminated surface the brakes may not hold and full power can blast debris into the propeller: follow the POH (possibly a rolling start).(Private Pilot ACS (FAA-S-ACS-6C), PA.IV.E.S7-S8; AFH)
- •Rotate at the POH speed; climb at the obstacle clearance speed or VX +10/-5 knots until the actual obstacle is cleared, however high it is (50 feet above the surface applies only when there is no obstacle or you're simulating one); then VY +10/-5 knots to a safe maneuvering altitude.(Private Pilot ACS (FAA-S-ACS-6C), PA.IV.E.S9-S11)
- •Use the POH flap setting and performance charts; obstacle-clearance distances assume their technique.(Your airplane's POH/AFM)
- •VX is close to the stall: an aggressive pull or a gust can stall it. Hold the speed precisely.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
- •Gear and flaps: the ACS accepts retraction after a verified positive rate or per the manufacturer; the AFH short-field technique keeps them in the takeoff position until the obstacle is cleared and you're at VY, then gear, then flaps in increments, then climb power. Where the POH differs (for gear or flaps), the POH governs.(Private Pilot ACS (FAA-S-ACS-6C), PA.IV.E.S12; Airplane Flying Handbook (FAA-H-8083-3C), Ch. 6)
- •Plan the abort point before you go. To abort: throttle to idle and maximum braking while keeping straight, per the POH, to stop in the runway left. Braking works far less on grass, wet or contaminated surfaces, so set the abort point earlier there.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
What you should know
Performance and speeds K1 · K2 · K3 · R1
- Run the POH takeoff distance chart for the actual weight, pressure altitude, temperature, wind and surface, including the distance over a 50-foot obstacle.(PHAK (FAA-H-8083-25C), Aircraft Performance)
- VX gives the steepest climb (most height per distance): the speed for clearing obstacles. Some POHs publish an obstacle clearance speed instead.(PHAK (FAA-H-8083-25C), Aircraft Performance)
- Set the flaps the POH recommends for a short-field takeoff.(Your airplane's POH/AFM)
- Choose the runway with the most length and headwind, and the fewest obstacles; if it’s marginal, don’t go.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
Flying it
- Taxi to the very start of the runway and line up on the centerline.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
- Before the roll: the checklist, the radio calls, the correct runway verified, the wind found (with or without indicators), the controls positioned for it, takeoff trim set, and scan for aircraft, vehicles, people, wildlife, wires and obstacles. Then, on a firm surface, hold the brakes, add full power, check the engine indications, release, and keep straight with rudder; check again before rotation.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs; FAA-S-ACS-6C, PA.IV.E.S1-S8)
- Keep the elevator about neutral in a low-drag attitude, and rotate smoothly at or near VX, or at the POH lift-off or obstacle-clearance speed, which governs. Don't pitch to the VX attitude before you have VX speed. If the airplane lifts off early on its own, stay in ground effect and lower the pitch to accelerate to VX. Never hold it on the ground with forward elevator to reach a number: that causes wheelbarrowing.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
- Fly VX by attitude: set the VX pitch attitude on outside references, trim it, and cross-check the airspeed only briefly; keep your eyes outside and hands off the gear and flap controls until clearance is assured. As you accelerate after liftoff you need progressively more back pressure to hold VX (otherwise it creeps toward VY and flattens the climb), and carry right rudder for the strong left yaw at full power and high angle of attack.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
- After liftoff in a crosswind, hold a wings-level crab to track the extended centerline; don't make a low-altitude turn into the wind. Follow any noise abatement procedure.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs; FAA-S-ACS-6C, PA.IV.E.S14-S15)
- Once clear of the actual obstacle (or at 50 feet above the surface if simulating one), lower the nose to VY. When stabilized at VY, retract the gear, then the flaps in increments (unless the POH says otherwise) to avoid a sudden loss of lift, then set normal climb power. A positive rate and obstacle clearance alone aren’t the cue.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
Wind, surface and wake on takeoff R2
- Crosswind: start the roll with full aileron into the wind and reduce it as speed builds; use rudder to hold the centerline. After liftoff, turn into the wind (crab) to track the extended centerline.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
- A headwind shortens the ground roll; a tailwind lengthens it a lot. Use the POH chart’s wind corrections, and avoid tailwind takeoffs when you have a choice.(PHAK (FAA-H-8083-25C), Aircraft Performance)
- Gusts and wind shear are different. In ordinary gusty wind, use the POH guidance for extra margin. Wind shear, especially a microburst or thunderstorm outflow, can drop the airspeed suddenly after liftoff: don't take off into known or reported wind shear; wait for it to pass.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
- Wake turbulence behind a larger airplane taking off: note its rotation point and lift off before it only at your normal rotation speed (never force an early liftoff), then climb above its path and stay upwind of it or turn away. If you can't, which is the usual case for a trainer behind a jet, ask for a delay (ATC uses timed intervals, such as 2 minutes behind a heavy, 3 for an intersection or opposite-direction departure behind a large airplane), and never assume you can outclimb it.(AIM, Chapter 7, Wake Turbulence)
- Grass, wet, snowy or uphill surfaces lengthen the takeoff roll. Apply the POH corrections, and add your own margin.(PHAK (FAA-H-8083-25C), Aircraft Performance)
Planning for the takeoff that goes wrong R3
- Before you roll, decide where you’ll abort: if the airplane isn’t at the expected speed by a chosen point, or anything looks or sounds wrong, close the throttle and stop straight ahead.(Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs)
- If the engine fails after liftoff with runway left, land on it. If it fails at low altitude past the runway, lower the nose to hold best glide speed and land roughly straight ahead, turning only enough to avoid obstacles.(Airplane Flying Handbook (FAA-H-8083-3C), Emergency Procedures)
- Turning back to the runway at low altitude is how many engine failures turn fatal: it needs far more altitude than most pilots expect, and a steep, slow turn can stall and spin.(Airplane Flying Handbook (FAA-H-8083-3C), Emergency Procedures)
Low, slow and busy R4 · R5 · R6
- Takeoffs and landings are where traffic converges: look for airplanes on final and on the runway before you line up or turn final, and use landing lights.(AC 90-48, Pilots' Role in Collision Avoidance)
- Close to the ground there’s no room to recover. A skidding turn to final, a nose-high climb or a stretched glide can stall and spin; flight into terrain or obstacles can follow a distraction.(Airplane Flying Handbook (FAA-H-8083-3C), Approaches and Landings)
- Fly the airplane first. Finish checklists and radio calls before the critical moments, and if you’re overloaded on final, go around.(Risk Management Handbook (FAA-H-8083-2A))
Before you release the brakes: the brief R3 · R4
- Brief it before brake release: the abort point, the landing area you'll use if the engine fails after liftoff, and your minimum turn-back altitude (no turn back below it, or without training). If it fails: lower the nose immediately to prevent a stall and coordinate first, then glide toward that area, essentially straight ahead; best glide speed is the refinement once control is secured.(Airplane Flying Handbook (FAA-H-8083-3C), Ch. 5-6)
- Wake turbulence behind a large airplane: delay, or lift off before its rotation point, climb above its flight path and stay upwind of it. Above alone isn't enough: the vortices sink and drift downwind.(AIM 7-4-6)
On the flight
ACS standards
- Climb at the recommended obstacle clearance speed or VX +10/-5 knots until the obstacle is cleared (or 50 feet AGL with no obstacle or a simulated one).(Private Pilot ACS (FAA-S-ACS-6C), PA.IV.E.S10)
- Then VY +10/-5 knots to a safe maneuvering altitude.(Private Pilot ACS (FAA-S-ACS-6C), PA.IV.E.S11, S13)
What your instructor is watching for
Your instructor watches whether you use all the runway, check power before releasing the brakes, rotate at the right speed, hold VX precisely without over-rotating, and transition to VY and clean up at the right time.
Scenarios
Decide what you would do first, then see the worked answer.
Climbing at VX, a gust drops your airspeed 8 knots below VX.
What do you do? See the worked answer
Lower the nose to recover the airspeed. Being below VX gives a worse climb and moves you toward a stall; clearing the trees depends on holding the speed.
Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs
You clear the obstacle and immediately raise all the flaps.
What can happen? See the worked answer
The airplane can sink as the wing loses lift. Wait until you’re clear of the obstacle and stabilized at VY, then retract the flaps in increments as the POH says.
Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs
You reach your abort point with the airspeed well below what you expected.
What do you do? See the worked answer
Abort: throttle to idle, maximum braking while keeping straight with rudder, per the POH. Continuing on a short runway with poor acceleration leaves no way out.
Airplane Flying Handbook (FAA-H-8083-3C), Takeoffs and Departure Climbs
Common mistakes
Starting the roll partway down the runway.
Lost runway behind you is useless.
Instead: Taxi to the very beginning before lining up.
Rotating early or too steeply, or pinning it on the ground.
Rotating early or steeply adds drag and can stall; forcing it to stay on the runway with forward elevator causes wheelbarrowing.
Instead: Rotate at the POH speed to the VX attitude; if it lifts off early, fly it in ground effect to VX.
Staying at VX too long.
Engine cooling suffers and you’re close to the stall for no reason.
Instead: Accelerate to VY once the obstacle is cleared.
