Steep turns on the checkride and the altitude loss that starts before you even roll in

The maneuver that fails the most checkride applicants isn’t the one that looks hardest on paper. Steep turns are fundamentally an exercise in energy management, and the mistake that costs most pilots their altitude happens in the two seconds before the turn — not during it. Understanding the physics behind the maneuver transforms steep turns from a white-knuckle struggle into one of the most satisfying demonstrations of coordinated flight.

What Do the ACS Standards Actually Require?

The Airman Certification Standards for the private pilot certificate require a steep turn at 45 degrees of bank, plus or minus 5 degrees. The tolerances are:

• Altitude: within 100 feet of entry altitude
• Heading: roll out within 10 degrees of entry heading
• Airspeed: within 10 knots of entry airspeed

For the commercial certificate, those tolerances tighten to 50 feet and 5 knots.

On paper, those numbers sound generous. In practice, pilots who don’t understand the underlying physics find themselves chasing deviations for the entire 360 degrees.

Why Do You Lose Altitude Before the Turn Even Starts?

In straight and level flight, the wings produce lift equal to the airplane’s weight — one G. At 45 degrees of bank, the wings must produce roughly 1.4 Gs to maintain altitude. That’s approximately 40 percent more lift than a moment before.

That extra lift comes from two sources: increased angle of attack (back pressure) and added power to overcome the increased induced drag.

Here’s where most students go wrong. They pick a reference point, roll to 45 degrees, and then start adding back pressure. The roll takes a couple of seconds, and during those seconds, the airplane is banked with no additional lift being generated. By the time back pressure is applied, 40 to 50 feet are already gone.

That altitude loss occurred before the turn really started. Now you’re behind for the entire maneuver.

How to Enter a Steep Turn Without Losing Altitude

Lead with back pressure as you roll in — not after. This is the single most effective correction for steep turn performance. Think of it as a coordinated movement: as bank angle increases, back pressure increases proportionally. By the time the bank reaches 45 degrees, the back pressure should already be set to hold altitude.

Here’s the full entry procedure, built from the ground up:

1. Stabilize first. Pick a round-number altitude — 3,500 or 4,000 feet. Trim for straight and level at maneuvering speed or your instructor’s recommended speed, typically 90 to 100 knots in most trainers. If you’re not trimmed before entry, you’ll fight the yoke the entire turn.

2. Clear the area. Two 90-degree clearing turns or a full 360-degree scan. The examiner is watching for genuine visual clearing, not a token head bob.

3. Pick a reference point. A road, tower, or landmark on the horizon. Note the heading on the directional gyro as backup.

4. Roll in smoothly with coordinated back pressure. Ailerons and elevator together, gradual and proportional.

5. Add power as you approach 45 degrees of bank. In a Cessna 172 or Piper Cherokee, expect to add roughly 100 to 200 RPM. Fine-tune once established.

Should You Trim During the Turn?

Once established at 45 degrees with correct back pressure, a small amount of nose-up trim — roughly half a turn of the trim wheel — can reduce control pressure for the full 360 degrees. This keeps you from fatiguing on the yoke.

The critical caveat: remove that trim during rollout, or the nose will pitch up sharply as the wings return to level. Some instructors teach this technique, some don’t. Try it in practice and decide if it helps.

Where Should You Look During a Steep Turn?

The second most common mistake is fixating on the altimeter. The altimeter lags. By the time it shows a loss of altitude, that loss happened three seconds ago. Reacting to stale information means constantly chasing corrections.

Use the sight picture outside the windshield as the primary altitude reference. In a left steep turn in most low-wing airplanes, the horizon intersects a specific point on the cowling when altitude is being held. Learn that sight picture — it’s faster and more accurate than any instrument.

Use the panel as a cross-check, not a primary reference. Glance at the altimeter, airspeed, and bank angle on the attitude indicator. But eyes belong outside, on the horizon, for the majority of the maneuver.

How Do You Roll Out on Heading?

At 45 degrees of bank, the airplane turns at roughly three degrees per second. It takes several seconds to roll from 45 degrees back to wings level. Waiting until the reference point is dead ahead guarantees overshooting the heading.

Lead the rollout by approximately half the bank angle — about 20 to 25 degrees before the reference point. Some airplanes need slightly more or less lead; 20 degrees is a reliable starting point.

During rollout, simultaneously reduce back pressure and reduce power. If back pressure stays in as the wings level, all that lift redirects straight up and the airplane balloons 50 feet above target altitude. The rollout is a coordinated reversal: as bank decreases, back pressure decreases, power returns to cruise setting.

What If You Lose Altitude During the Turn?

If you’ve lost 80 feet mid-turn, do not pull harder. Increasing back pressure at 45 degrees of bank tightens the turn, increases load factor, bleeds airspeed, and moves closer to an accelerated stall. That is the worst possible response.

The correct recovery: shallow the bank to approximately 30 degrees, allow the airplane to climb back to altitude, then re-establish 45 degrees. A shallow correction is a safe correction. Examiners would far rather see a smooth, controlled altitude recovery than an aggressive pull that risks a stall at 45 degrees of bank.

The slow erosion pattern is what to watch for: lose 20 feet, pull harder, airspeed drops 3 knots, lose another 20 feet, pull harder still. Now the airplane is nose high, slow, over-banked, and the stall horn is chirping. Recognizing this spiral early and responding with a bank reduction — not more back pressure — is exactly the judgment the examiner wants to see.

The Five Most Common Steep Turn Mistakes

1. Not adding back pressure during roll-in. The back pressure must lead, not follow.
2. Fixating on the instruments. The horizon is the primary reference; instruments are the cross-check.
3. Forgetting to add power. The airplane needs more energy at a higher angle of attack. Add those RPMs.
4. Over-banking past 45 degrees. At 60 degrees of bank, load factor reaches 2 Gs and stall speed increases by roughly 40 percent. Use the attitude indicator to verify bank angle until the sight picture is second nature.
5. Sloppy rollout. Blowing through the heading, ballooning on exit, or leaving power in. The rollout is part of the maneuver.

Practice Both Directions Equally

Most pilots have a comfortable turning direction and an awkward one. Left turns typically feel more natural because visibility over the cowling is better. Right turns feel odd because the nose blocks part of the view. The examiner will ask for both directions. Don’t let the less-practiced direction be the one that catches you off guard.

The standard to aim for: both directions should feel the same.

Key Takeaways

• Lead with back pressure as you roll in — this single fix eliminates the altitude loss that defeats most applicants
• Add 100–200 RPM on entry to compensate for increased induced drag at 45 degrees of bank
• Use the horizon as your primary altitude reference, not the altimeter, which lags by several seconds
• Lead rollout by 20–25 degrees and coordinate the reduction of back pressure and power as wings level
• If you lose altitude mid-turn, shallow the bank — never pull harder at 45 degrees of bank
