ICAO Annex 11

Annex 11 contains the standards and recommended practices for air traffic services, including ATS objectives, separation, flight information and alerting service responsibilities.

ATC clearance

An authorization for an aircraft to proceed under specified conditions issued by an air traffic control unit; it does not relieve the pilot in command of responsibility for safe flight.

Alerting service

An ATS service that notifies appropriate organizations when an aircraft is in distress or overdue, and assists such organizations as required.

Flight information service

A service providing advice and information useful for the safe and efficient conduct of flights, including weather, NOTAM, aerodrome and hazard information, without separation.

VFR minima

Visual flight rules require specified flight visibility and distance from cloud; in controlled airspace, typical minima are 5 km visibility and 1500 m horizontally, 300 m vertically from cloud.

Flight plan closure

A flight plan is closed when the aircraft reports arrival and the ATS unit records it; failure to close triggers alerting service and search and rescue action.

RVSM airspace

Reduced vertical separation minimum airspace permits 1000 ft vertical separation between approved aircraft at or above FL 290; non-approved aircraft require 2000 ft separation.

Radar separation minimum

The minimum horizontal distance between aircraft under radar control, typically 5 NM en route and 3 NM in terminal areas where approved, with identification maintained.

Runway-in-use

The runway designated by the aerodrome control tower as the one in use for landing and take-off at a given time, based on wind and traffic conditions.

Aerodrome operating minima

The minimum visibility, RVR and cloud base conditions required for take-off, approach and landing at an aerodrome, depending on facilities and aircraft equipment.

Control zone (CTR)

Controlled airspace extending upwards from the surface to a specified upper limit around an aerodrome, established to protect aerodrome traffic.

Transfer of control

The agreed transfer of responsibility for providing air traffic control service from one ATS unit to another, requiring coordination and acknowledgement.

SIGMET

A meteorological warning of significant en-route weather phenomena such as thunderstorms, severe turbulence, icing or volcanic ash that may affect flight safety.

QNH

The altimeter setting that, when set on the altimeter, indicates elevation above mean sea level; used below the transition altitude.

NOTAM

A notice distributed by means of telecommunication containing information concerning the establishment, condition or change of any aeronautical facility, service or procedure.

AIP

The Aeronautical Information Publication is a State publication containing permanent aeronautical information essential to air navigation, including aerodromes, airspace and procedures.

Read-back requirement

The mandatory repetition by the pilot of ATC clearances and instructions affecting levels, headings, speeds, frequencies and runways, to confirm correct reception.

Squawk 7600

The transponder code indicating radio communication failure; the aircraft follows applicable communication failure procedures and ATC provides separation.

Situational awareness

The perception and understanding of the current and predicted state of the operational environment, enabling controllers to anticipate conflicts and act appropriately.

Just culture

A safety culture in which errors are reported and learned from without punishment, while reckless or intentional violations remain subject to disciplinary action.

Uncertainty phase

An emergency phase declared when an aircraft fails to report within a specified time or is otherwise considered uncertain, prompting ATS to initiate inquiries.

Interception procedures

Standard ICAO signals and procedures used when a military aircraft intercepts a civil aircraft, requiring ATC to inform the intercepted aircraft and coordinate.

Wake turbulence category

A classification of aircraft by maximum take-off mass (Light, Medium, Heavy, Super) used to determine wake turbulence separation minima between aircraft.

Approach category

A classification based on reference speed (Vref) used to determine instrument approach minima and spacing, ranging from category A to E.

MAYDAY

The international distress signal used in radiotelephony to indicate that an aircraft is threatened by serious and imminent danger and requires immediate assistance.

PAN-PAN

The international urgency signal used in radiotelephony to indicate a situation concerning the safety of an aircraft but not requiring immediate distress action.

Transition altitude

The altitude at which the altimeter is changed from QNH to standard pressure 1013.2 hPa when climbing, and vice versa when descending.

LVP

Low visibility procedures activated when visibility or RVR falls below specified values, involving reduced runway occupancy, increased separation and special safeguards.

RNAV

Area navigation allowing aircraft to fly on any desired path within coverage of navigation aids or GNSS, rather than directly to or from a station.

TRM

Team resource management uses communication, briefing, cross-checking and assertiveness to optimize controller performance and reduce errors during high workload.

Composite separation

A separation method combining vertical, lateral and longitudinal elements, each of which must be independently assured and monitored by the controller.

Airspace class D

Controlled airspace where IFR and VFR flights are permitted; IFR receives separation from IFR, and VFR receives traffic information about other flights.
