What are the criteria for a stabilized approach in a Cessna 172?

On a visual approach in the Cessna 172, a stabilized approach requires tracking the extended centerline on a three-degree glide path, flying between 65 and 75 knots per your weight and POH, fully configured with flaps at the intended setting, descending at approximately 500 feet per minute or less, and making only small control corrections. All five criteria must be met at your stabilization gate.

At what altitude should I go around if my approach is unstabilized?

For visual approaches, your personal gate should be no lower than 300 feet AGL. Airlines require stabilization by 1,000 feet AGL in visual conditions and 500 feet AGL on instrument approaches. If any stabilized approach criterion is not met at the gate, execute a go-around.

Will I fail my private pilot checkride for going around?

No. FAA guidance for applicants states that going around when in doubt is never the wrong answer. Examiners evaluate whether you recognized an unstabilized approach and responded correctly. You will not be failed for going around unnecessarily - but you can be failed for continuing an approach when you should have discontinued it.

How do I retract flaps during a go-around in the Cessna 172?

Do not retract all flaps at once. From 30 degrees, come to 20 degrees first to reduce drag while preserving needed lift close to the ground. Once you have a positive rate of climb and airspeed is sufficient to retract further safely, come to flaps up. Verify the specific speeds and sequence in your aircraft's POH before flight.

Why do pilots keep pressing through unstabilized approaches instead of going around?

Three patterns appear consistently in the data: commitment bias (being mentally finished flying before the landing is actually complete), sunk cost instinct (unwillingness to abandon effort already invested in the approach), and a training gap (practicing go-arounds only as an instructor-prompted drill rather than as a self-initiated decision from a deteriorating approach).

The Unstabilized Approach: The Go-Around Decision Examiners Are Watching For Every Time

An unstabilized approach is one of the most well-documented and preventable accident causes in general aviation. The National Transportation Safety Board (NTSB) has traced the pattern repeatedly: a pilot commits to the landing, the setup deteriorates, and no go-around is executed. Understanding the specific criteria for a stabilized approach - and making the go-around a trained reflex - directly addresses this risk.

What Are the Five Criteria for a Stabilized Approach?

A stabilized approach is not a vague concept. It has specific, definable criteria that must be met by a defined altitude gate.

1. Correct flight path. On a standard visual approach, you should be tracking the extended centerline and flying a three-degree glide path. A PAPI (Precision Approach Path Indicator) showing two whites and two reds means you are on slope. All white means too high; all red means too low. On a VASI (Visual Approach Slope Indicator), the mnemonic is red over white, you’re alright - upper bar red, lower bar white means on path. All red indicates dangerously low; all white means you have climbed above the slope.

2. Correct airspeed. For most training aircraft, the target is approximately 1.3 times the stall speed in landing configuration, or whatever the Pilot’s Operating Handbook (POH) specifies for your weight and conditions. In the Cessna 172, that typically falls between 65 and 75 knots depending on weight and flap setting. You should be at that speed - not chasing it and not correcting by ten knots every few seconds.

3. Correct configuration. Gear down if applicable, and flaps at your intended landing setting. Not still working on configuration at 500 feet above the ground.

4. Manageable rate of descent. For general aviation training aircraft, that generally means 500 feet per minute or less. A descent rate of 900 fpm with a mile to the threshold is not stabilized, and the math does not work out to a good landing.

5. Small corrections only. From the stabilization gate to the flare, you should be able to maintain all of the above without large control inputs. If you are wrestling the airplane or chasing the centerline with significant corrections, the approach is not stabilized.

If any one of these criteria is not met at your gate altitude, the correct response is a go-around - not an attempt to salvage the approach.

Where Is the Stabilization Gate?

The airline industry codified gate altitudes into mandatory policy. Most major carriers require that by 500 feet above field elevation on an instrument approach, or 1,000 feet above field elevation in visual conditions, the aircraft must meet all stabilized approach criteria. If it does not, a go-around is executed - not discussed.

For student and private pilots flying visual approaches, a practical personal gate is 300 feet AGL. At that point, run a quick check: Am I on the glide path? Am I on speed? Am I configured? Am I tracking centerline? If any answer is no, go around.

The gate is not a suggestion. It is a decision point, and the decision has already been made before you get there.

Why Do Pilots Continue Unstabilized Approaches?

The NTSB accident record and data from the Aviation Safety Information Analysis and Sharing (ASIAS) program show this is a known, documented, preventable accident category. Understanding why it keeps happening is the first step in breaking the pattern.

Commitment bias. The airport is in sight, the runway is getting bigger, and mentally the pilot is already done flying. Going around feels like giving up. But the runway does not reward commitment - physics only know the energy state of the aircraft at that moment.

Sunk cost instinct. Three miles of effort on an approach makes discontinuing it feel like waste. Flying does not work that way. Effort on final earns no credit; results do.

A training gap. Most student pilots practice go-arounds as a discrete drill - the instructor calls it, the student executes. Practicing a self-initiated go-around from a deteriorating approach, without any prompt, is a different skill. It is also the one that matters in the real world.

How Do I Execute a Go-Around Correctly?

Go-around execution follows a specific sequence. Knowing it before you need it is the point.

Full power. Apply it deliberately and smoothly. In the Cessna 172, this means full throttle. Make it a controlled motion.

Pitch for climb attitude. Simultaneously adjust pitch to arrest the descent and establish a climb. In the 172, that is approximately 8 to 10 degrees nose up, depending on airspeed.

Carb heat off. If carb heat was on, remove it when going to full throttle. Carb heat reduces power output and you need full power available.

Flap retraction - incrementally. Do not retract full flaps all at once. In the 172 with 30 degrees of flaps, come up to an intermediate setting - typically 20 degrees - first. This reduces drag without eliminating the lift still needed close to the ground at low airspeed. Once a positive rate of climb is established and airspeed is sufficient, retract to flaps up. Verify the specific numbers and sequence in your POH.

Right rudder. At full power, P-factor, torque, and slipstream effect all yaw the nose left. Apply right rudder proactively to maintain coordinated flight. At low airspeed, near the ground, at maximum power, coordination is not optional.

Communicate. At a towered field, advise ATC. At a non-towered field, announce on the CTAF (Common Traffic Advisory Frequency). Keep it simple: “Cessna seven three four Sierra Foxtrot, going around.”

Fly a full pattern. There is no prize for a tight 270-degree turn to get back quickly. Take the time, fly a complete pattern, and give yourself the best setup for a stabilized approach on the next pass.

What Do Two Consecutive Go-Arounds Tell You?

Two go-arounds in a row on the same runway under the same conditions is data. The environment is communicating something - whether that is a crosswind at your personal limit, lower-than-expected visibility, or technique that has degraded from fatigue on a long cross-country. That pattern is a signal to seriously consider whether landing at this airport, in these conditions, at this moment is the right decision at all.

What Does the ACS Expect From You on the Checkride?

The Airman Certification Standards (ACS) for the private pilot certificate addresses the go-around explicitly. The examiner is evaluating three things: whether you recognize when a go-around is necessary, whether you initiate it at the appropriate point, and whether you execute it correctly.

The examiner is not evaluating whether your approach was perfect. Approaches are not always sterile - weather shifts, gusts push you off centerline. What the examiner is watching is whether you recognized what was happening and responded correctly.

A student who identifies an unstabilized approach and executes a clean, coordinated go-around with proper power, pitch, flap management, and communication is demonstrating exactly the aeronautical decision-making the checkride exists to assess. A student who presses through a deteriorating approach and lands long, fast, or hard is demonstrating the opposite - even if nothing breaks. The examiner saw the decision, or the absence of one.

The phrase that appears in failed checkride debriefs: You did not fail because the approach was bad. You failed because you did not recognize when to discontinue it.

When in doubt, go around. The FAA has stated this directly in guidance for applicants. An examiner will never fail a student for going around when they did not strictly need to. The reverse is not true.

How Should I Practice the Go-Around Decision?

The self-initiated go-around is a distinct skill from the instructor-prompted drill. It needs to be practiced as its own task.

Ask your instructor to let you practice without any prompting from them. Set your personal gate at 300 feet AGL on every approach. At that altitude, run the check: configured, on speed, on glide path, tracking centerline. If any answer is no, go around without negotiating with yourself. Do this consistently until the call becomes automatic.

That habit - recognizing the moment, making the call yourself, without hesitation - may be the most important one built during primary training.

Key Takeaways

A stabilized approach requires five criteria: correct flight path, correct airspeed, proper configuration, manageable descent rate (≤500 fpm for training aircraft), and only small corrections from gate to flare.
The personal stabilization gate for visual approaches should be no lower than 300 feet AGL. Airlines use 1,000 feet AGL for visual conditions and 500 feet AGL for instrument approaches.
The go-around is a skill and a decision, not a failure. Practicing the self-initiated go-around - without instructor prompting - is what converts a drill into genuine aeronautical decision-making.
Correct go-around execution: full power, climb pitch, carb heat off, flaps retracted incrementally (not all at once), proactive right rudder, communicate, fly a complete pattern.
Two consecutive go-arounds on the same runway is a signal to reassess whether the landing should be attempted at all.
