Definition
An intentional maneuver involving an abrupt change in an aircraft's attitude, an abnormal attitude, or abnormal acceleration, that is not necessary for normal flight. Examples include loops, rolls, spins, and similar maneuvers. Acrobatic flight is regulated under 14 CFR Part 91 and is prohibited in certain airspace and below specified altitudes, and requires the use of parachutes when carrying passengers.
Plain English
Flying maneuvers like loops, rolls, and spins that go beyond what's needed for normal flight. They involve sharp changes in the aircraft's position or unusual forces on the airplane.
Context Anchor
You will see this term in FAA rules, aircraft operating limitations, and discussions about what maneuvers an aircraft is approved to perform.
Derivation
From the Greek 'akrobatos,' meaning 'walking on tiptoe' or 'climbing high,' built from 'akros' (high, extreme) and 'bainein' (to walk). The sense of performing extreme or daring movements carried over into flying when pilots began doing maneuvers that pushed the limits of normal handling.
Why Pilots Care
Pilots must know the precise limits because acrobatic flight is prohibited over congested areas, in certain airspace, and without appropriate aircraft certification or waivers.
Intuition Check
Acrobatic flight does not only mean airshow stunts. If the maneuver is intentional, unusual, abrupt, or creates abnormal forces, and it is not needed for normal flight, it may count as acrobatic flight.
Example Sentence 1
Before practicing acrobatic flight, the pilot climbed to 4,000 feet AGL and confirmed the area was clear of other traffic.
Example Sentence 2
Federal regulations prohibit acrobatic flight over a congested area without prior authorization from the FAA.
