Configuration. This is a general term, which normally refers
to the position of the landing gear and flaps.

Constant-speed propeller. A controllable-pitch propeller
whose pitch is automatically varied in flight by a governor
to maintain a constant rpm in spite of varying air loads.

Continuous flow oxygen system. System that supplies
a constant supply of pure oxygen to a rebreather bag that
dilutes the pure oxygen with exhaled gases and thus supplies a
healthy mix of oxygen and ambient air to the mask. Primarily
used in passenger cabins of commercial airliners.

Control and performance. A method of attitude instrument
flying in which one instrument is used for making attitude
changes, and the other instruments are used to monitor the
progress of the change.

Control display unit. A display interfaced with the master
computer, providing the pilot with a single control point
for all navigations systems, thereby reducing the number of
required flight deck panels.

Controllability. A measure of the response of an aircraft
relative to the pilot's flight control inputs.

Controlled airspace. An airspace of defined dimensions
within which ATC service is provided to IFR and VFR flights
in accordance with the airspace classification. It includes Class A,
Class B, Class C, Class D, and Class E airspace.

Control pressures. The amount of physical exertion on the
control column necessary to achieve the desired attitude.

Convective weather. Unstable, rising air found in
cumuliform clouds.

Convective SIGMET. Weather advisory concerning
convective weather significant to the safety of all aircraft,
including thunderstorms, hail, and tornadoes.

Conventional landing gear. Landing gear employing a third
rear-mounted wheel. These airplanes are also sometimes
referred to as tailwheel airplanes.

Coordinated flight. Flight with a minimum disturbance of
the forces maintaining equilibrium, established via effective
control use.

COP. See changeover point.

Coriolis illusion. The illusion of rotation or movement in an
entirely different axis, caused by an abrupt head movement,
while in a prolonged constant-rate turn that has ceased to
stimulate the brain's motion sensing system.

Coupled ailerons and rudder. Rudder and ailerons are
connected with interconnected springs in order to counteract
adverse yaw. Can be overridden if it becomes necessary to
slip the aircraft.

Course. The intended direction of flight in the horizontal
plane measured in degrees from north.

Cowl flaps. Shutter-like devices arranged around certain
air-cooled engine cowlings, which may be opened or closed
to regulate the flow of air around the engine.

Crew resource management (CRM). The application of
team management concepts in the flight deck environment.
It was initially known as cockpit resource management,
but as CRM programs evolved to include cabin crews,
maintenance personnel, and others, the phrase "crew
resource management" was adopted. This includes single
pilots, as in most general aviation aircraft. Pilots of small
aircraft, as well as crews of larger aircraft, must make
effective use of all available resources; human resources,
hardware, and information. A current definition includes
all groups routinely working with the flight crew who
are involved in decisions required to operate a flight
safely. These groups include, but are not limited to pilots,
dispatchers, cabin crewmembers, maintenance personnel,
and air traffic controllers. CRM is one way of addressing
the challenge of optimizing the human/machine interface
and accompanying interpersonal activities.

Critical altitude. The maximum altitude under standard
atmospheric conditions at which a turbocharged engine can
produce its rated horsepower.

Critical angle of attack. The angle of attack at which
a wing stalls regardless of airspeed, flight attitude, or

Critical areas. Areas where disturbances to the ILS localizer
and glideslope courses may occur when surface vehicles or
aircraft operate near the localizer or glideslope antennas.

CRM. See crew resource management.
