Eights on pylons is the maneuver that most confuses students conceptually — and that confusion shows up immediately on the checkride. Once you understand why it works, the technique becomes intuitive.
What the ACS Actually Requires
The ACS for eights on pylons requires:
- Select two suitable pylons at the correct pivotal altitude
- Fly a figure-eight ground track with the extended lateral axis of the aircraft consistently pointing at the pylon
- Divide attention between pylon reference and traffic/collision avoidance
- Apply wind correction to maintain the correct ground track
- Roll out on the entry heading ±10°
There are no altitude tolerances like steep turns — the entire maneuver is altitude management. If your line of sight drifts off the pylon, you're at the wrong altitude.
The Most Common Errors
- Not knowing pivotal altitude before starting — calculate it on the ground: (GS in mph)² ÷ 11.3 or (GS in knots)² ÷ 12.3
- Fixating on the pylon and forgetting the ground track — the figure-eight must be symmetrical
- Climbing or descending through pivotal altitude — the line of sight to the pylon should stay on the wingtip reference
- Forgetting wind correction — without it, you'll drift and your pylon reference will drift with you
- Banking the wrong direction when the line of sight moves — if the pylon moves aft, climb; if it moves forward, descend
How to Execute It Correctly
- Select two pylons approximately 0.5–1 mile apart, far enough from populated areas
- Calculate pivotal altitude before the maneuver
- Enter at 45° to the first pylon, at pivotal altitude
- Roll into a bank that keeps your wingtip reference on the pylon — adjust bank as needed for wind
- As you come off the first pylon, cross the midpoint between pylons on a 45° entry to the second
- Roll into the second turn — the bank angle will differ because of wind
- Continue the figure-eight, making altitude adjustments (not bank adjustments) to keep the pylon fixed
Why Students Fail This on Checkride Day
The conceptual gap is what causes the bust: students think it's about bank angle. It's not. It's about pivotal altitude. Examiners see the line of sight drift immediately because they've watched hundreds of students fight the wrong variable.
Checkride Ready helps you rehearse the mental flow of every maneuver — including the ones like eights on pylons where concept and execution have to merge.
