What’s the point of ground reference maneuvers?
Confession: I hated ground reference maneuvers as a student pilot. S-turns, turns around a point, rectangular courses—it all seemed like busy work, a way to rack up flight hours without learning anything or having any fun. I wanted to perfect my landings and learn how to fly 200-mile trips, and all this time locked in the practice area wasn’t helping.
Or so I thought. While it took awhile, my flight instructor finally broke through and explained why we were spending so much time on ground reference maneuvers. He told me to stop focusing on the minutiae and the rigid FAA test standards, and to start focusing on the bigger picture. We were really learning how to read the wind, how to visualize the airplane’s track over the ground, and how to coordinate control inputs. It was about aircraft mastery and making it go exactly where we wanted, no matter what the wind conditions.
This little speech worked. I didn’t instantly love turns around a point, but I did begin to appreciate that doing this simple maneuver really well was going to help me make better landings.
If your flight instructor hasn’t explained why you’re doing all these seemingly arbitrary maneuvers (and I suspect many don’t), you may feel the same way I did. So instead of memorizing a checklist or obsessing about two degrees of bank, let’s review the point of these exercises.
This one seems simple, and it really is, but that doesn’t mean it isn’t important. The whole idea here is to learn how to fly a perfect traffic pattern, which matters because a good landing results from a good approach. That’s harder than it sounds, as you’ll see if you attend a fly-in sometime, where patterns can vary wildly from perfect rectangles to abstract art patterns.
The key is to adjust for wind, and do it almost without thinking. As obvious as it may sound, the first step to doing that is recognition. As the Airman Certification Standards (ACS) say, you need to see the “Effects of wind on ground track and relation to a ground reference point.” That means choosing an appropriate reference point (the runway is an obvious one in the pattern) and adjusting to stay a consistent distance from it. Vary both heading and bank angle to keep the pattern rectangular throughout. But don’t just guess—have a rough idea of wind conditions before you start the maneuver so you can start out with wind correction in place.
I’d also suggest you really focus on the first turn, simulating the downwind-to-base leg. This will require a steeper bank and a turn of more than 90 degrees, so that when you roll out on base you are correcting for the crosswind. Many pilots—even experienced ones—get sloppy here, and the result is overbanking on the base-to-final turn to get lined up on final. This not good, and can set you up for a loss of control event.
Don’t stress about finding a perfectly square field and don’t stress about the length of the pattern. Focus on correcting for drift and making smooth, coordinated turns.
Turns around a point
This is a nice complement to the rectangular course, because it allows you to practice those all-important turns in the pattern without leveling the wings. The goal is the same—keep the airplane a constant distance from your reference point (water towers are my favorite here)—but the technique is slightly different. You can’t crab into the wind with the wings level, so your only tool is bank angle.
The challenge here is to juggle a number of tasks simultaneously. Once again, the ACS offers a clue, pointing out that a common error is “Failure to divide attention between airplane control and orientation.” It’s one thing to visualize your ground track throughout the maneuver, but it’s another to keep this updated while you’re varying the bank angle. If you find yourself focused on one of those tasks for more than about 10 seconds, it’s probably time to check the other.
This is great practice for the traffic pattern, when things can get busy in a hurry and you must divide your attention. So if you’re burned out on turns around a point, remind yourself that this is all about making better base and final turns—it’s not just academic.
To dive deeper, watch this video tip for a detailed description of this essential maneuver. Sporty’s Learn to Fly Course has one of these maneuver guides for each maneuver you’ll have to learn for the Private Pilot checkride.
The last of the “big three maneuvers” was always my nemesis as a student pilot. It’s easy to visualize, but there’s actually a lot going on. This time the emphasis is learning to manage the effects of bank angle and groundspeed on both the rate and the radius of turn. A good S-turn is really just a turn around a point that’s been split in half, with one turn to the left and one to the right, so step one is to apply the lessons of the previous maneuver to this one. Visualize your ideal track, consider the wind, and decide ahead of time which turns will be steeper and shallower.
Once you have a plan in mind, start the maneuver over a nice, straight road or other landmark. Just like with the first two maneuvers, try to start out headed downwind, so the first turn is the steepest (the downwind-to-base turn, once again). As you pass through 90 degrees, slowly but steadily shallow the bank until you’re wings level as you pass back over the road.
A challenge with S-turns is to stay coordinated. As you’re trying to adjust your ground track and vary the bank angle, it’s easy to either forget to use rudder or overdo it. You may think you’re “forcing” the nose to go where you want, but it’s not precise flying and could lead to bad habits. You always want to fly with the ball centered in the pattern. Always.
Two advanced tips
By your third lesson, you’ll probably have been introduced to some or all of these maneuvers. As you gain experience, you should be increasing your proficiency and confidence. Something I learned by accident one day might be helpful here: after you’ve learned the basics, go fly these maneuvers when there’s some real wind. I found it pretty hard to see drift with 4 knots of wind, but during one lesson when it was blowing over 25 knots at 1000 feet AGL, the lightbulb went off. This might mean a tougher landing, maybe even one the flight instructor has to make, but I think you can learn a lot from such conditions.
You can also use modern technology to help you evaluate your performance much more precisely than I could 25 years ago. The easiest is ForeFlight’s track log feature, which allows you to record your ground track using your iPad’s GPS and then review it after your lesson. This is automatic and doesn’t have to distract you from flying, but can really make a post-flight debriefing session come alive. Was your S-turn perfectly symmetrical? The track log doesn’t lie.
If you really want to geek out, use a GoPro to record video of your control inputs and panel instruments. You can load this into an app like CloudAhoy and see both your ground track and controls at the same time. Or use a Stratus to record complete flight data, including pitch and roll. This will allow you to see a glass cockpit instrument overlay while you play back your flight. Just remember to use these tools as enhancements to your training, and don’t let them get in the way of your flight instructor’s guidance.

Very helpful. I’m closing in on my checkride and appreciated some of the tips especially regarding turns around a point
Excellent tips and underlines the importance of why we spend so may have time learning these sometimes tedious maneuvres
You know , your turns around a point graphic displays the opposite correction than required- the steepest bank angle should be on the downwind side and vice versa. I almost went cross-eyed trying to reconcile the illustration for a few seconds!
What I see in the article now has the steepest bank on downwind. The wind is from the north; the steepest bank angle is when heading south with a tailwind. Usually these turns are shown going counterclockwise, but this one is clockwise.
I agree with Mr Allen.
A shallower bank angle on the downwind side of a turn around a point, as illustrated, would result in an egg shaped ground trace because the winds would be pushing the plane farther from the point on the downwind side and toward the point on the upwind side.
As a commercial student, I appreciate the discussion of the value of these maneuvers. As an instructor in military systems operations, one thing that was ingrained in us when we were in training was to always, ALWAYS, begin and end a lesson with the value in application of the material. Doesn’t the CFI FOI cover this concept? If not, it should.
I think the article has some very good advice. Especially regarding the why of doing what we do in an airplane as well as the what. I learned to fly a very long time ago. No one ever mentioned the PTS during training (this was long before ACS) and it was a very practical rather than academic training. When I did my check ride with a grizzled old WWII P-47 pilot, I had no specific maneuver expectations, it was simply go fly with him. I flew what I was told to fly, land as I was told to land (regular, short field, soft field) and passed. I think that the fly to the airplane not to the test is a good philosophy. Become a pilot who knows why on taxi your controls are positioned down and away from a rear quartering wind.
Good timing on this article. This is exactly what my next lesson with my CFI will cover.
