cockpit human resources. The
assumption is that errors are going to
happen in a complex system with
error-prone humans.
COEFFICIENT OF LIFT—See
LIFT COEFFICIENT.
COFFIN CORNER—The flight
regime where any increase in airspeed
will induce high speed mach buffet
and any decrease in airspeed will
induce low speed mach buffet.
CONDITION LEVER—In a turbine
engine, a powerplant control that controls
the flow of fuel to the engine.
The condition lever sets the desired
engine r.p.m. within a narrow range
between that appropriate for ground
and flight operations.
CONFIGURATION—This is a
general term, which normally refers to
the position of the landing gear
and flaps.
CONSTANT SPEED
PROPELLER— A controllablepitch
propeller whose pitch is
automatically varied in flight by a
governor to maintain a constant r.p.m.
in spite of varying air loads.
CONTROL TOUCH—The ability to
sense the action of the airplane and its
probable actions in the immediate
future, with regard to attitude and
speed variations, by sensing and
evaluation of varying pressures and
resistance of the control surfaces
transmitted through the cockpit flight
controls.
CONTROLLABILITY—A measure
of the response of an aircraft relative
to the pilot’s flight control inputs.
CONTROLLABLE PITCH
PROPELLER—Apropeller in which
the blade angle can be changed during
flight by a control in the cockpit.
CONVENTIONAL LANDING
GEAR—Landing gear employing a
third rear-mounted wheel. These
airplanes are also sometimes referred
to as tailwheel airplanes.
COORDINATED FLIGHT—
Application of all appropriate flight
and power controls to prevent slipping
or skidding in any flight condition.
COORDINATION—The ability to
use the hands and feet together
subconsciously and in the proper
relationship to produce desired results
in the airplane.
CORE AIRFLOW—Air drawn into
the engine for the gas generator.
COMBUSTION CHAMBER—The
section of the engine into which fuel
is injected and burned.
COMMON TRAFFIC
ADVISORY FREQUENCY—The
common frequency used by airport
traffic to announce position reports in
the vicinity of the airport.
COMPLEX AIRCRAFT—
An aircraft with retractable landing
gear, flaps, and a controllable-pitch
propeller, or is turbine powered.
COMPRESSION RATIO—1. In a
reciprocating engine, the ratio of the
volume of an engine cylinder with the
piston at the bottom center to the
volume with the piston at top center.
2. In a turbine engine, the ratio of the
pressure of the air at the discharge to
the pressure of air at the inlet.
COMPRESSOR BLEED AIR—
See BLEED AIR.
COMPRESSOR BLEED
VALVES—See BLEED VALVE.
COMPRESSOR SECTION— The
section of a turbine engine that
increases the pressure and density of
the air flowing through the engine.
COMPRESSOR STALL—In gas
turbine engines, a condition in an
axial-flow compressor in which one
or more stages of rotor blades fail to
pass air smoothly to the succeeding
stages. Astall condition is caused by a
pressure ratio that is incompatible
with the engine r.p.m. Compressor
stall will be indicated by a rise in
exhaust temperature or r.p.m.
fluctuation, and if allowed to
continue, may result in flameout and
physical damage to the engine.
COMPRESSOR SURGE—Asevere
compressor stall across the entire
compressor that can result in severe
damage if not quickly corrected. This
condition occurs with a complete
stoppage of airflow or a reversal of
airflow.

COWL FLAPS—Devices arranged
around certain air-cooled engine
cowlings which may be opened or
closed to regulate the flow of air
around the engine.
CRAB—A flight condition in which
the nose of the airplane is pointed into
the wind a sufficient amount to counteract
a crosswind and maintain a
desired track over the ground.
CRAZING—Small fractures in
aircraft windshields and windows
caused from being exposed to the
ultraviolet rays of the sun and
temperature extremes.
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
