regulations gap analysis	REG gap analysis	Michae­lBurov
rejected landing	A planned landing that is discontinued for reasons such as conflicting traffic, weather, or landing surface obstacles
release cue	Cross hairs used to determine the time to release your bombs if the bombsight is not displayed in the HUD
release time	An expression used in radiocommunication to indicate a departure time restriction issued to a pilot by ATC (either directly or through an authorized relay) when it is necessary to separate a departing aircraft from other traffic
remote communications air/ground facility	An unstaffed VHF/UHF transmitter/receiver facility used to facilitate direct contact between pilots and controllers. Sometimes these facilities are not equipped with emergency frequencies 121.5 MHz and 243.0 MHz.
remote communications outlet	A facility remotely established from an FSS or FIC for the provision of communications between aircraft and this FSS or FIC
remotely piloted aircraft	A power-driven aircraft, other than a model aircraft, that is designed to fly without a human operator on board. aircraft (UA) and unmanned aircraft system
Remotely Piloted Aircraft Regulations	RPA Regulations	Michae­lBurov
remotely piloted aircraft system	A remotely piloted aircraft, its associated remote pilot stations, the required command and control links and any other components as specified in the type design
rendezvous	A prearranged meeting at a given time and location from which to begin an action or phase of an operation or to which to return after an operation
REO display	Radar/Electro-Optical display
repair & overhaul	R&O	Michae­lBurov
repair and overhaul	R&O	Michae­lBurov
reporting point	A specific fix in relation to which the position of an aircraft can be reported
required navigation performance	A statement of the navigation performance accuracy necessary for operation within a defined airspace
required navigation performance approach	RNP approach	Michae­lBurov
required navigation performance capability airspace	As geographically delineated in the Designated Airspace Handbook (DAH) controlled airspace within the Canadian Domestic Airspace (CDA) designated for area navigation (RNAV) operations. Only aircraft certified as meeting the required navigation performance capability (RNPC) are permitted to operate on published, high level fixed RNAV routes or receive improved ATC separation minimums based on RNPC. Certification is dependent upon crew training and navigation equipment that permits position determination within ± 4 NM.
required navigation performance type	A containment value expressed as a distance in nautical miles from the intended position within which flights would be for at least 95 percent of the total flying time. For example, RNP 4 represents a navigation accuracy of ± 4 NM on a 95 percent containment basis.
required visual reference	In respect of an aircraft on an approach to a runway, the section of the approach area of the runway or the visual aids that, when viewed by the pilot of the aircraft, enable the pilot to make an assessment of the aircraft position and the rate of change of position relative to the nominal flight path in order to continue the approach and complete the landing
resolution advisory	An advisory issued by airborne collision avoidance system (ACAS) alert and collision avoidance system (TCAS) to alert pilots to potential conflicting air traffic and provide them with a suggested flight- path change in the vertical plane to reduce the possibility of collision
