CLEARED FOR (TYPE OF) APPROACH - Air Traffic Control authorization for an aircraft to execute a specific instrument approach procedure to an airport; e.g., "Cleared for ILS Runway 36 approach." (See Instrument Approach Procedure, Approach Clearance) (Refer to Federal Air Regulations Part 91)
CLEARED FOR APPROACH - Air Traffic Control authorization for an aircraft to execute any standard or special instrument approach procedure for that airport. Normally, an aircraft will be cleared for a specific Instrument Approach Procedure. (See Instrument Approach Procedure, Cleared for (type of) Approach.) (Refer to Federal Air Regulations Part 91)
CLEARED FOR TAKE-OFF - Air Traffic Control authorization for an aircraft to depart. It is predicated on known traffic and known physical airport conditions.
CLEARED FOR THE OPTION - Air Traffic Control authorization for an aircraft to make a touch-and-go, low approach, missed approach, stop-and-go, or full stop landing at the discretion of the pilot. It is normally used in training so that an instructor can evaluate a student's performance under changing situations. (See Option Approach)
CLEARED THROUGH - Air Traffic Control authorization for an aircraft to make intermediate stops at specified airports without refiling a flight plan while enroute to the clearance limit.
CLEARED TO LAND - Air Traffic Control authorization for an aircraft to land. It is predicated on known traffic and known physical airport conditions.
CLEARWAY - An area beyond the take-off runway under the control of airport authorities within which terrain or field obstacles may not extend above specified limits. These areas may be required for certain turbine-powered operations and the size and upward slope of the clearway will differ depending on when the aircraft was certified. (Refer to Federal Air Regulations Part 1)
CLIMBOUT - That portion of flight operation between take-off and the initial cruising altitude.

CLIMB RATES (USAF)
(1)
AIR TRAFFIC CONTROL CLIMB RATES - Information which is published on Departure Procedures (e.g., SIDs) and Instrument Approach Procedures (IAPs), for the purpose of advising Air Traffic Control of the average climb rate to achieve a Minimum Crossing Altitude.

(2)
MINIMUM CLIMB RATES - Information which is published on Departure Procedures (e.g., SIDs) and Instrument Approach Procedures (IAPs), for the purpose of advising Air Traffic Control of the minimum climb rate to achieve the Required Obstacle Clearance (ROC).

CLIMB TO VFR - ATC authorization for an aircraft to climb to VFR conditions within Class B, C, D, and E surface areas when the only weather limitation is restricted visibility. The aircraft must remain clear of clouds while climbing to VFR. (See Special VFR)
CLOSE PARALLELS - Two parallel runways whose extended centerlines are separated by at least 3,400 feet, but less than 4,300 feet, having a Precision Runway Monitoring (PRM) system that permits simultaneous independent ILS approaches.
