Clearing Turns

Turns executed at a bank angle of approximately $30^\circ$ with each turn being at least $90^\circ$ (or one single $180^\circ$ turn) performed before maneuvers to ensure the area is clear of traffic.

Positive Exchange of Flight Controls

A formal three-step process ('Your flight controls', 'My flight controls', 'Your flight controls') accompanied by visual verification used to transfer aircraft control between pilot and student.

Minimum Controllable Airspeed (MCA)

An airspeed at which any further increase in angle of attack, increase in load factor, or reduction in power would result in an immediate stall.

Cross-Control Stall

A stall occurring when flight controls are crossed (aileron in one direction and rudder in the opposite), often resulting from an overshot base-to-final approach turn.

Accelerated Stall

A stall that occurs at a higher indicated airspeed due to excessive maneuvering loads imposed by steep turns or abrupt changes in flight path.

Chandelles

A maximum performance $180^\circ$ climbing turn maneuver that starts at cruise/$V_O$ airspeed and finishes wings level within $5\,\text{knots}$ of stall speed.

Lazy Eights

A flight maneuver consisting of symmetric $180^\circ$ turns with constantly changing pitch and bank angle in an 8-shaped pattern across $45^\circ$, $90^\circ$, and $135^\circ$ reference points.

Eights on Pylons

A commercial ground-reference maneuver requiring the pilot to maneuver around two pylons, adjusting altitude to maintain line-of-sight on the pylon at pivotal altitude.

Steep Spirals

A power-off gliding turn maneuver performed at steep bank angles ($45^\circ$ to $60^\circ$) designed to dissipate altitude rapidly over a fixed ground point.

Five T's

An instrument procedural memory aid standing for Turn, Time, Twist, Throttle, and Talk.

Pattern A

An instrument practice procedure designed to develop aircraft control without deliberate thought using consecutive timed turns on cardinal headings.

Pattern B

An instrument practice maneuver incorporating simultaneous changes in airspeed, bank, power, and descending turns to prepare for holding patterns and procedure turns.

Vertical 'S'

An instrument maneuver consisting of continuous climbs and descents at $500\,\text{FPM}$ and $90\,\text{KIAS}$ paired with standard rate $180^\circ$ turns.
