Definition
The lazy eight is the only maneuver in the FAA commercial standard in which nothing is ever stabilised. FAA-S-ACS-7 describes it as a constant change of pitch and roll rate and airspeed, with a bank of approximately 30 degrees at the steepest point, flown as symmetrical loops. The airplane climbs and turns away from a reference point, reaches maximum pitch-up around the 45-degree point, passes through the 90-degree point at maximum bank and minimum airspeed, then descends and rolls out onto the reciprocal heading before repeating the pattern in the opposite direction.
The graded tolerances apply at the 180-degree point of each loop rather than continuously: altitude within plus or minus 100 feet of entry altitude, airspeed within plus or minus 10 knots of entry airspeed, and heading within plus or minus 10 degrees. Coordinated flight has to be maintained throughout, and as with the other commercial performance maneuvers the ACS requires an altitude that keeps the maneuver no lower than 1,500 feet AGL. The knowledge items include the phases of the maneuver from entry to recovery and the accelerated-stall risk that comes with changing load factor at low airspeed.
Why It Matters for Flight Schools
Instructors use the lazy eight as the maneuver that tells them whether a commercial student has genuinely developed feel, because it cannot be flown by chasing instruments. Everything is moving at once, so the only workable technique is to fly attitudes against the horizon and let the numbers arrive. Students who have learned to pass earlier tests by fixating on the airspeed indicator usually struggle here first.
Because the tolerances are measured against the student's own entry values rather than fixed numbers, the lazy eight also rewards consistency: a repeatable entry makes every subsequent checkpoint easier to hit, which is a habit worth grading explicitly in the syllabus.
How Aviatize Handles This
Recording lazy eights as a discrete syllabus objective in Aviatize lets an instructor grade the specific checkpoint that failed — altitude, airspeed or heading at the 180-degree point — rather than marking the maneuver as a whole unsatisfactory. Over a course that distinction is what tells a chief instructor whether the issue is energy management or directional control, and the record supports the pre-checkride recommendation with evidence.
Frequently Asked Questions
- What are the tolerances for lazy eights?
- FAA-S-ACS-7 grades the 180-degree point of each loop: altitude within plus or minus 100 feet of the entry altitude, airspeed within plus or minus 10 knots of the entry airspeed, and heading within plus or minus 10 degrees. Bank is approximately 30 degrees at the steepest point and the maneuver must finish no lower than 1,500 feet AGL.
- Why is it called a lazy eight?
- The name describes the path the nose traces against the horizon, which looks like a figure eight lying on its side. The word lazy refers to the unhurried, continuously changing nature of the maneuver, not to the precision required, which is among the highest in the commercial standard.
- What makes lazy eights harder than steep turns?
- A steep turn has one target bank angle and one target altitude to hold. In a lazy eight pitch, bank and airspeed are all changing continuously and are never stabilised, so the pilot has to fly attitude against the horizon and anticipate rather than react to instrument indications.
