C of G centre of gravity. The point on an aircraft through which the entire aircraft's weight may be assumed to act (i.e. around which the aircraft, if suspended, would balance). C of G limits are the most forward and rearward positions of the C of G permitted for safe operation. An aircraft loaded outside its C of G limits can be difficult or impossible to control.
C of P centre of pressure, the point through which the total effect of lift may be said to act on an aeroplane.
Com(m)(s) communication(s)
CPL Commercial Pilot's Licence

CRP compulsory reporting point.
CRT cathode ray tube (like a television). Used in flight deck displays of new-generation airliners, business aircraft and military jets instead of conventional instruments. See also EFIS,.
critical altitude the highest density altitude at which it is possible to maintain the maximum continuous rated power or manifold pressure of an aero engine.
critical engine the engine on a multi-engined aircraft whose failure would most seriously effect performance or handling of the aircraft, through asymmetric effects or loss of power to systems such as hydraulics.
CRS course the intended direction of flight in the horizontal plane expressed in degrees of the compass.
c/s call sign
CS constant-speed (propeller). A variable-pitch propeller which maintains constant rpm by automatically changing blade angle. Also CSU, constant-speed unit.
