chamfered tooth. charted visual flight procedure (CVFP) approach
chamfered tooth -The tooth of the gear on the rotating
magnet or the distributor gear which is beveled to
identify it for use when timing the magneto.
chamois - A piece of soft leather used to filter gasoline.
Gasoline will pass through a chamois, but water will
not. Gasoline that has been filtered through a chamois
can be considered to be free from water.
chandelle - A maximum performance 180" climbing
turn. It involves continual changes in pitch, bank,
airspeed, and control pressures. During the maneuver,
the airspeed gradually decreases from the entry speed
to a few knots above stall speed at the completion of
the 180" turn.
charged. 2. The physical condition that gives rise to an
electric field.
charging a battery - The preparation of battery for
service by passing low-voltage DC through the battery
in the opposite direction of normal battery output. A
lead acid battery should be recharged when a cell has a
hydrometer reading of 1.240 or below. A filly charged
battery reads about 1.300 on the hydrometer.
charging current - A current passed through a
secondary cell that restores the active material on the
plates to a condition that allows them to change
chemical energy into electrical energy.
charging stand - A handy and compact arrangement of
air conditioning service equipment containing a
vacuum pump, manifold set, and a method of
measuring and dispensing the refrigerant.
change of state - The transformation of a substance
from one form (state) to another such as a solid
changing to a liquid. In meteorology, a change of state
usually refers to the change of water from one form to
Charles' law - A law of physics which states that if a
another.
gas is held at a constant pressure, it will expand in
Examples include: condensation - vapor to liquid;
direct relationship to the increase in its absolute
evaporation - liquid to vapor; sublimation - solid (ice)
temperature.
to vapor; freezing - liquid to solid; melting - solid to
liquid. chart - 1. A pictorial presentation of data. 2. A graph. - - 3.
A graphic representation of the operation of engine
changeover point (COP)- The point at which a pilot
changes frequencies between navigation aids when
other than the midpoint on an airway.
channel. - A IIICL~I
bent in to a U-shape
channel iron - Extruded steel
either extruded or bent into a
U-shape.
channel section - A form of
structural material that has the
cross sectional shape of a
channel or the letter U.

characteristic curves - 1. A series of graphically
presented curves that describe in mathematical terms
the characteristics of lift and drag produced by an
airfoil section. 2. A graph that shows the performance
of an electron tube or a transistor under various
operating conditions.
characteristic potential difference - The theoretical
potential difference produced by a chemical cell using
specific pole materials.
characteristics of learning - Effective learning shares
several common characteristics. Learning is dynamic
and should be purposeful, based on experience,
multifaceted, and involve an active process.
charcoal - Black porous carbon.
performance, fuel consumption, horsepower, or
limitation of somc spccific unit. 4. A map.
-:LL .- --.L-..l.l -- chart NOTAMS - Jeppesen Chart NOTAMS include
UL
significant information changes affecting Enroute,
Area, and Terminal charts. Entries are published until
the temporary condition no longer exists, or until the
permanent change appears on revised charts. Enroute
chart numbers I panel numbers I letters and area chart
identifiers are included for each entry in the enroute
portion of thc chart NOTAMs. To avoid duplication of
information in combined Enroute and Terminal Chart
NOTAMs, navaid conditions, except for ILS
components, are listed only in the Enroute portion of
the Chart NOTAMs. All times are local unless
otherwise indicated. Arrows indicate ncw or revised
information. Chart NOTAMs are only an abbreviated
service. Always ask for pertinent NOTAMs prior to
flight.
chart, navigation - A special map used for aerial
navigation that gives the location and the necessary
information about all of the navigation aids. A chart
shows the grids of latitude and longitude and provides
a surface for plotting courses and locating fixes.
charted VFR flyways - Charted VFR Flyways are
flight paths recommended for use to bypass areas
heavily traversed by large turbine-powcrcd aircraft.
Pilot compliance with recommended flyways and
associated altitudes is strictly voluntary. VFR Flyway
Planning charts are published on the back of existing
VFR Terminal Area charts.
charge - 1. A quantity of electricity. If the charged
material holds a greater number of electrons than
it is said to be charged. If the charted visual flight procedure (Cmp) approach -
material has a deficiency of electrons, it is positively
An approach conducted while operating on an
