Stalls aren't really about going slow. They're about asking the wing to do something it physically can't. If you walk away from this post with one thing, let it be that the wing always quits at the same angle of attack β never at the same airspeed. Everything else flows from there.
What a stall actually is
A stall happens when the wing exceeds its critical angle of attack. Most general aviation airfoils give up somewhere between 15 and 18 degrees. Past that, the smooth airflow over the top of the wing separates, lift collapses, and the airplane stops flying like you expect.
Here's the part that trips people up: that critical angle doesn't care about your weight, altitude, or attitude. It's the same in cruise, in a steep turn, upside down, or fully loaded. What changes is the airspeed required to reach that angle. That's why an angle of attack indicator is a much better stall predictor than the airspeed indicator most of us have been staring at our entire flying lives.
Stall speed is a moving target
The Vs and Vs0 numbers in your POH are calibrated to one specific scenario: max gross weight, 1G, power off, wings level. Change anything and the actual stall speed shifts. The FAA Airplane Flying Handbook (FAA-H-8083-3C), Chapter 5 lays this out plainly:
- 30-degree bank: stall speed up about 7% (1.15G)
- 45-degree bank: up about 19% (1.41G)
- 60-degree bank: up about 41% (2G)
- Flaps extended: down 10 to 25%, depending on the airframe
- 10% under MTOW: down about 5%
A Cessna 172 that books a 47-knot stall straight and level will quit on you near 67 knots in a 60-degree bank. That's roughly the speed you'd see climbing out after rotation.
The flavors of stall you'll meet
Power-on stall. Climb attitude, throttle forward. Classic over-rotation on takeoff or a botched go-around. Prop wash and P-factor try to yaw you left at the break, and you're close to the ground. This is the dangerous one.
Power-off stall. Throttle back, simulating final approach or an engine-out. Usually caused by stretching the glide and pulling back, thinking pitch buys you distance. It buys you angle of attack instead.
Accelerated stall. Steep turn, often the infamous base-to-final pull. Indicated airspeed can read above book Vs, but the load factor pushed real stall speed above whatever you're flying. Fast, mean, and often fatal at pattern altitude.
Secondary stall. You recovered from the first one and pulled too hard, too soon. The wing goes right back to critical AOA before it had time to fly again.
Cruise stall. Wind shear or a sharp vertical gust spikes AOA without warning. More common in convective weather than people admit.
The warnings the airplane gives you
Most pilots who actually break a wing in a real stall ignored three or four cues before it happened. The airplane talks to you:
- Aerodynamic buffet β separated airflow shaking the tail. Honest, mechanical, hard to miss.
- Mushy controls β ailerons especially feel sloppy as you approach CL max.
- Increasing sink rate with the nose up β you're behind the power curve.
- Stall warning horn β the reed or vane usually screams 5 to 10 knots before the break.
- Unusually nose-high attitude in power-on, or rapidly bleeding airspeed in power-off.
One caveat: high-performance airframes like the Cirrus SR22 or Mooney can have subtle or late buffet. Don't rely on seat-of-pants alone. Trust the horn, trust the AOA indicator if you have one, and trust the procedure.
The recovery, in order
The FAA Airplane Flying Handbook and AC 120-109A both teach the same sequence. Order matters.
- Reduce angle of attack. Yoke or stick forward, firmly. Not violent, not tentative. Push until the buffet stops and airspeed comes back. This is the counter-intuitive one β pilots want to pull, and pulling is what got you here.
- Add power, smoothly to full in most piston singles. Turbines and turboprops follow the POH to avoid compressor stall or flameout.
- Level the wings with rudder first. Aileron on a stalled wing can deepen the stall on the down-going side and start a spin. Use rudder until the air reattaches.
- Return to level flight. Ease the back pressure in. Don't pull hard or you'll get a secondary stall.
| Step | Action | Common mistake |
|---|---|---|
| 1 | Stick forward | Hesitating or pulling more |
| 2 | Power up | Forgetting throttle entirely |
| 3 | Rudder to level | Reaching for aileron first |
| 4 | Recover attitude | Yanking back too hard |
When a stall becomes a spin
A spin is an asymmetric stall: one wing more deeply stalled than the other, generating autorotation. AC 61-67C (Stall and Spin Awareness Training) describes the three ingredients you need, all at the same time:
- The wing is stalled
- There's yaw β usually from rudder input or P-factor
- Time β autorotation needs a half to full turn to fully develop
Your window to break the chain before a developed spin is short β typically 2 to 4 seconds after the break. Catch it there and the airplane never finishes a rotation. Miss it and you're now flying a developed spin, which uses a different recovery.
PARE β the spin recovery mnemonic
PARE is the FAA's standard procedure, straight out of the Airplane Flying Handbook and reinforced in every AOPA Air Safety Institute Stall/Spin Safety Spotlight:
| Letter | Action | Why |
|---|---|---|
| P β Power | Idle | Reduces P-factor and prop-induced yaw |
| A β Ailerons | Neutral | Aileron on a stalled wing perpetuates rotation |
| R β Rudder | Full opposite to rotation | Stops the yaw driving the spin |
| E β Elevator | Forward of neutral | Breaks the stall |
Once rotation stops, neutralize rudder immediately so you don't enter a spin the other direction, then recover the dive smoothly within G limits.
Important: most normal-category airplanes (Cessna 172, Cherokee, SR22) are not certified for intentional spins. Spin training happens in utility-category or aerobatic airframes β a 152 in utility loading, a Super Decathlon, a Citabria, an Extra. Always check your POH before you go upside-down on purpose.
Cirrus and CAPS β a different doctrine
The SR22 deserves its own paragraph. Cirrus stall behavior is documented as more abrupt than a Skyhawk, which is exactly why the airframe ships with the Cirrus Airframe Parachute System. Above 2,000 ft AGL the doctrine is to attempt conventional recovery first. Below that, in an unrecovered loss of control, the procedure is to pull the red handle. Don't try to outsmart the airplane the manufacturer designed around the chute.
Frequently asked
Can I accidentally spin a non-spin-certified airplane? Yes. Normal-category certification means the manufacturer didn't guarantee recovery β it doesn't mean the airplane won't depart. PARE still works in most cases, but margins are thinner.
How much altitude should a clean recovery cost? In training, 50 to 150 feet is reasonable. Down low, any loss can be fatal. Hence the rule: don't stall below 1,000 ft AGL, except on landing.
Are AOA indicators worth installing? New Cirrus, Diamond, and Cessna NXi airplanes ship with AOA standard. For legacy fleets, aftermarket kits (Garmin GI-260, Alpha Systems) run roughly $1,500 to $2,500 installed. Cheap insurance.
What to actually practice
- Pull your POH. Calculate stall speed in 30, 45, and 60-degree banks at typical weights.
- Brief yourself on what your airplane feels like before the break β buffet, horn timing, control feel.
- Take a UPRT (Upset Prevention and Recovery Training) course. It's the highest-ROI hour of training money you'll spend all year.
- Practice approach-to-stall recognition above 3,000 ft AGL with a CFI, focusing on stopping the maneuver before the break, not just recovering from it.
If you fly with AeroCopilot, work load-factor stall speeds into your pre-flight briefing β especially heavy, short-runway, or pattern-tight days when an aggressive turn to final starts looking tempting.
