Spin Awareness
Spin awareness is knowing how a spin develops, the situations that lead to one, and the recovery, so you never need it close to the ground.
Why this one matters
Stall-spin accidents are among the deadliest in general aviation because they usually begin too low to recover: in the pattern, on departure, or in a low-altitude maneuver. A commercial pilot needs to recognize the setups and keep the airplane coordinated and unstalled, so the spin never starts.
Can’t miss
- •A spin needs a stalled wing and yaw. Stay coordinated and below the critical angle of attack, and the airplane can't spin.(PHAK (FAA-H-8083-25C), Aerodynamics of Flight)
- •Phases: entry, incipient (from the stall to a fully developed spin, which takes two to four turns in most airplanes), developed (steady rotation and descent), and recovery. Recover from an incipient spin before 360° of rotation; the first turn costs about 1,000 feet and each later one about 500.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins)
- •Recover as early as you recognize it. A common procedure (PARE): Power idle, Ailerons neutral, Rudder full opposite the rotation, Elevator briskly forward; hold until rotation stops, then neutralize the rudder and ease out of the dive. The POH procedure comes first.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins; Your airplane's POH/AFM)
- •The classic accident is the skidding turn from base to final: rudder into the turn, opposite aileron to hold the bank, and a pull.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins)
- •An aft center of gravity makes spins flatter and recovery harder or impossible; stay inside the weight and balance envelope.(PHAK (FAA-H-8083-25C), Aerodynamics of Flight)
- •Unless the manufacturer specifically approves spins, they are prohibited; many airplanes are placarded against them, and approval is often limited to the utility category's weight and CG. No multiengine airplane is approved for intentional spins, and their recovery characteristics are generally very poor.(Your airplane's POH/AFM; Airplane Flying Handbook (FAA-H-8083-3C), multiengine airplanes)
- •Spin training for the commercial certificate is not required (except for CFIs), but spin awareness is: prevention is the goal.(AC 61-67C, Stall and Spin Awareness Training)
What you should know
The aerodynamics K1 · K2
- In a spin, both wings are stalled, but one more deeply; the difference in lift and drag keeps the airplane rotating and descending.(PHAK (FAA-H-8083-25C), Aerodynamics of Flight)
- Yaw at the stall (a skid, a slip, high power without rudder) starts the rotation. Load factor raises the stall speed, so a spin can come from an accelerated stall in almost any attitude. Weight, center of gravity, power, flaps and gear all change how it develops; an aft CG makes it flatter.(PHAK (FAA-H-8083-25C), Aerodynamics of Flight)
- Entry: stall with yaw, a wing drops. Incipient: rotation building, not yet stable. Developed: steady rotation, airspeed and descent rate. Recovery: rotation stops and the wing unstalls.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins)
Recovery K3 · R3
- Follow the POH. The general procedure: power to idle, ailerons neutral, full rudder opposite the rotation, then immediately brisk, positive elevator forward of neutral (don't wait for the rotation to stop), hold both until rotation stops, neutralize rudder, then recover gently from the dive without a secondary stall or exceeding limits. Find the rotation direction from the turn indicator's symbolic airplane, not the ball.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins; Your airplane's POH/AFM)
- Recover from an incipient spin immediately, before 360° of rotation; a developed spin takes more turns and more altitude (about 1,000 feet for the first turn, 500 for each after). Intentional spins are planned to finish recovery at or above 1,500 feet AGL.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins)
- Spin or spiral? In a spin the wing is stalled and the indicated airspeed stays low and roughly constant. In a spiral dive the wing is flying and the airspeed climbs; pulling only tightens it and adds G. Don't apply spin recovery to a spiral: power off, level the wings, then ease out.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins)
- Ailerons used in the direction of the rotation can make a spin worse; keep them neutral.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins)
How spins happen in real flying R1 · R2 · R4
- The base-to-final overshoot tightened with rudder; a turn back to the runway after an engine failure; a go-around with nose-up trim; a low-altitude steep turn; a departure stall without rudder.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins)
- Stall warnings (horn, light) must start at least 5 knots above the stall in each configuration, typically 5 to 10 knots (check the POH), and continue to the stall; they are angle-of-attack driven and can fail, and in an accelerated stall the warning comes at a higher speed. Buffet differs between airplanes. Know the other cues: mushy controls, quieter air noise, a high nose, sink.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins)
- Turbulence and gusts change the angle of attack suddenly; a microburst or wind shear can drop the airspeed in seconds; at high density altitude there is less power to recover with, and the true airspeed at the stall is higher.(PHAK (FAA-H-8083-25C), Aerodynamics of Flight)
Attention and traffic R5 · R6
- Spin training: confirm the POH and placards approve it at this weight and CG; check the 91.307 parachute rule; clear above and below for aircraft, terrain, obstacles and wires; and start high enough to recover by 1,500 feet AGL, with an instructor.(AC 61-67C, Stall and Spin Awareness Training; 14 CFR 91.307)
- Expect disorientation during a spin: fly the airplane first, and confirm the direction with outside cues and the turn indicator.(Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins)
- Distraction is how stalls happen in real flying: a frequency change, a passenger, traffic. Keep a scan outside and inside, and if in doubt, lower the nose first.(Risk Management Handbook (FAA-H-8083-2A))
Scenarios
Decide what you would do first, then see the worked answer.
An engine fails at 400 feet after takeoff.
Why not turn back to the runway? See the worked answer
A steep turn at low speed and altitude raises the stall speed and invites a stall-spin with no height to recover. Land mostly straight ahead.
Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins
A stall in a skidding turn: the airplane rolls sharply and starts to rotate.
What do you do? See the worked answer
Recover from the incipient spin at once: power idle, ailerons neutral, rudder opposite the rotation, nose forward; then recover from the dive.
Airplane Flying Handbook (FAA-H-8083-3C), slow flight, stalls and spins
You load cargo far aft in a light single for a charter-like flight.
What's the risk? See the worked answer
An aft CG makes the airplane less stable and spins harder to recover; stay within the weight and balance limits (spin approval is often only in the utility category's CG range).
PHAK (FAA-H-8083-25C), Aerodynamics of Flight
Common mistakes
Using aileron to stop the rotation.
It can deepen the stall and the spin.
Instead: Ailerons neutral, rudder opposite.
Pulling hard out of the dive.
It can cause a secondary stall or overstress.
Instead: Ease out gradually.
Tightening turns with rudder.
It creates the skidding stall-spin setup.
Instead: Use coordinated bank, or go around.
