Spin Awareness

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.

1 · Know these cold

  • •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)

2 · The lesson

The aerodynamics
  • 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
  • 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
  • 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
  • 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))

3 · Say it out loud

Answer each one out loud, then check yourself and mark how it went.

  1. Remember Recall it

    “What two things must happen for an airplane to spin?”

  2. Understand Explain why

    “Why does an aft center of gravity make spins more dangerous?”

  3. Apply Use it on a flight

    “Overshooting final, you notice yourself pushing rudder into the turn and holding opposite aileron. What do you do?”

4 · 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.

5 · Quick check

Answer, then reveal. Flag anything you want to see again.

  1. 1. Name the phases of a spin.

  2. 2. What does PARE stand for?

  3. 3. Which comes first: the POH or a general spin procedure?

  4. 4. Are multiengine airplanes spun intentionally?

  5. Scenario5. Low on final, overshooting, you feel the airplane yaw into the turn with a stall warning. What do you do?

Connect it

One situation that runs across this lesson and its neighbors in the same ACS area. Decide first, then check.

Connect it · Slow Flight & Stalls

Turning to avoid traffic, you pull hard in a steep bank at cruise power and the airframe buffets well above the published stall speed.

What happened, what's the recovery, and what makes it dangerous? Decide, then see the worked answer

An accelerated stall: the wing reached its critical angle of attack under a higher load factor, so at an airspeed above the 1 G stall speed. Stall speed rises with the square root of the load factor: about 1.41 times the 1 G stall speed at 2 G, twice it at 4 G. Accelerated stalls tend to break more abruptly and more severely than 1 G stalls, often with a wing drop, and can cost a lot of altitude. Recover by unloading first: release back pressure until the buffet and the stall stop. Then roll the wings level with coordinated controls, then add power as needed. Power doesn't unstall a wing; only reducing the angle of attack does. A spin needs a stalled wing plus yaw, so uncoordinated rudder at that moment, or aileron used to pick up a dropping wing while still stalled, can roll it into one. Speed matters too. At or below maneuvering speed, the wing stalls before the airplane reaches its limit load factor, which protects the structure. Above it, a hard pull can exceed the limit load factor before the wing reaches its critical angle of attack, with no stall to protect you. Maneuvering speed decreases as weight decreases.
