(2)
The Instrument Landing System localizer signal pattern usually specified as front course or back course.
(3)
The intended track along a straight, curved or segmented Microwave Landing System path. (See Bearing, Radial, Instrument Landing System and Microwave Landing System)
COURSE (JCS) - The intended direction of movement in the horizontal plane.
CRITICAL ENGINE - The engine which, upon failure, would most adversely affect the performance or handling qualities of an aircraft.
CROSS (FIX) AT (ALTITUDE) - Used by Air Traffic Control when a specific altitude restriction at a specified fix is required.
CROSS (FIX) AT OR ABOVE (ALTITUDE) - Used by Air Traffic Control when an altitude restriction at a specified fix is required. It does not prohibit the aircraft from crossing the fix at a higher altitude than specified; however, the higher altitude may not be one that will violate a succeeding altitude restriction or altitude assignment. (See Altitude Assignment, Altitude Restriction)
CROSS (FIX) AT OR BELOW (ALTITUDE) - Used by Air Traffic Control when a maximum crossing altitude at a specific fix is required. It does not prohibit the aircraft from crossing the fix at a lower altitude; however, it must be at or above the minimum IFR altitude. (See Minimum IFR Altitude, Altitude Restriction) (Refer to Federal Air Regulations Part 91)
CROSSWIND -
(1)
When used concerning the traffic pattern, the word means “crosswind leg”. (See Traffic Pattern)
(2)
When used concerning wind condition, the word means a wind not parallel to the runway or the path of an aircraft. (See Crosswind Component)
CROSSWIND COMPONENT - The wind component measured in knots at 90 degrees to the longitudinal axis of the runway.
CRUISE - Used in an Air Traffic Control clearance to authorize a pilot to conduct flight at any altitude from the minimum IFR altitude up to and including the altitude specified in the clearance. The pilot may level off at any intermediary altitude within this block of airspace. Climb/descent within the block is to be made at the discretion of the pilot. However, once the pilot starts descent and verbally reports leaving an altitude in the block he may not return to that altitude without additional Air Traffic Control clearance. Further, it is approval for the pilot to proceed to and make an approach at destination airport and can be used in conjunction with:
