ADMINISTRATIVE ORDER NO. ATS 2.01-3

Series of 1985

Pursuant to the pertinent provisions of Republic Act No. 776, (as amended) the following rules and regulations are hereby prescribed for the observance of all concerned.

This Administrative Order shall be known as Civil Air Regulations, governing Rules of the Air of the Philippines:

Chapter I – DEFINITIONS

The following words and phrases as used in this Administrative Order shall have the following meanings:

Acrobatic flight: Maneuvers intentionally performed by an aircraft involving an abrupt change in its attitude, an abnormal attitude, of an abnormal variation in speed.

Advisory airspace: A generic term meaning variously, advisory area(s) or advisory route(s).

Advisory area: A designated area within a flight information region where air traffic advisory service is available.

Advisory route: A route within a flight information region along which air traffice advisory service is available.

Aerodrome: A defined area on land or water (including any buildings installations and equipment) intended to be used either wholly or in part for the arrival, departure and surface movement of aircraft.

Aerodrome control service: Air traffic control service for aerodrome traffic.

Aerodrome control tower: A unit established to provide air traffic control service to aerodrome traffic.

Aerodrome traffic: All traffic on the maneuvering area of an aerodrome and all aircraft flying in the vicinity of an aerodrome.

Note: An aircraft is in the vicinity of an aerodrome when it is in, entering or leaving an aerodrome traffic circuit, and/or when it is within five(5) nautical miles of the aerodrome at traffic circuit altitudes.

Aerodrome traffic circuit: The specified path to be flown by aircraft in the vicinity of an aerodrome.

Aerodrome traffic zone: An airspace of defined dimensions established around an aerodrome for the protection of aerodrome traffic.

Aeronautical Information Publication: A publication issued by or with the authority of the Director and containing aeronautical information of a lasting character essential to air navigation.

Aeronautical station: A land station in the aeronautical mobile service. In certain instances, an aeronautical station may be placed on board a ship or on earth satellite.

Aeroplane: A power-driven heavier –than-air aircraft, deriving its lift in flight chiefly from aerodynamic reactions on surface which remain fixed under given condition of flight.

Aircraft: Any machine that can derive support in the atmosphere from the reactions of the air other than the reactions of the air against the earth’s surface.

Air ground control radio station: An aeronautical telecommunication station having primary responsibility for handling communications pertaining to the operation and control of aircraft in a given area.

Air traffic: All aircraft in flight or operating on the maneuvering area of an aerodrome.

Air traffic advisory service: A service provided within advisory airspace to ensure separation, insofar as possible, between aircraft which are operating on IFR flight plans.

Note 1: For convenience, the term “air traffic control clearance” is frequently abbreviated to “clearance” when used in appropriate contexts.

Note 2: The abbreviated term “clearance” may be prefixed by the words “taxi”, “take-off”, “departure”, “en-route”, “approach or landing” to indicate the particular portion of flight to which the air traffic control clearance relates.

Air traffic control service: A service provided for the purpose of:

1.       Preventing collision:

a)      between aircraft, and

b)      on the maneuvering area between aircraft and obstructions, and

2.       expediting and maintaining an orderly flow of air traffic.

Air traffic control unit: A generic term meaning variously area control center, approach control office or aerodrome control tower.

Air traffic service: A generic term meaning variously, flight information service, alerting service, air traffic advisory service, air traffic control service, area control service, approach control service or aerodrome control service.

Air traffic services reporting office: A unit established for the purpose of receiving reports concerning air traffic services and flight plans submitted before departure.

Note: An air traffic services reporting office may be established as a separate unit or combined with an existing unit, such as another air traffic service unit, or a unit of the aeronautical information services.

Air traffic services unit: A generic term meaning variously, air traffic control unit, flight information center or air traffic services reporting office.

Airway: A control area or portion thereof established in the form of a corridor equipped with radio navigational aids.

Alerting service: A service provided to notify appropriate organizations regarding aircraft in need of search and rescue aid, and assist such organizations as required.

Alternate aerodrome: an aerodrome specified in the flight plan to which a flight may proceed when it becomes inadvisable to land at the aerodrome of intended landing.

                           Note: An alternate aerodrome may be the aerodrome of departure.

Approach control office: A unit established to provide air traffic control service to controlled flights arriving at or departure from one or more aerodromes.

Approach control service: Air traffic control service for arriving or departing controlled flights.

Approach ATS authority: The relevant authority designated by the director responsible for providing air traffic services within the Manila FIR (Flight Information Region).

Apron: A defined area, on a land aerodrome, intended to accommodate aircraft for purposes of loading or unloading passengers, mail or cargo, refueling, parking or maintenance.

Area control center: A unit established to provide air traffic control service to controlled flights in control areas under its jurisdiction.

Area control service: Air traffic control service for controlled flights in control areas.

ATS route: A specified route designed for channeling the flow of traffic as necessary for the provision of air traffic services.

Note: The term “ATS route” is used to mean variously, airway, advisory route, controlled or uncontrolled route, arrival or departure route, etc.

Ceiling: The height above the ground or water of the base of the lowest layer of cloud below 6,000 meters (20,000 feet) covering more than half of the sky.

Change-over point: The point at which an aircraft navigating on ATS route segment defined by reference to very high frequency omni-directional redio rages is expected to transfer its primary navigational reference from the facility behind the aircraft to the next facility ahead of the aircraft.

Note: Change over points are established to provide the optimum balance in respect of signal strength and quality between facilities at all levels to be used and to ensure a common source of azimuth guidance for all aircraft operating along the same portion of a route segment.

Clearance limit: The point to which an aircraft is granted an air traffic control clearance.

Control area: A controlled airspace extending upwards from a specified limit above the earth.

Controlled aerodrome: An aerodrome at which air traffic control service is provided to aerodrome traffic.

Note: The term “controlled aerodrome” indicates that air traffic control service is provided to aerodrome traffic but does not necessarily imply that a control zone exists, since a control zone is required at aerodrome where air traffic control service will be provided to IFR flights, but not at aerodrome where it will be provided only to VFR flight.

Controlled airspace: An airspace of defined dimensions within which air traffic service is provided to controlled flights.

Controlled airspace (Instrument restricted): Controlled airspace within which only IFR flights are permitted.

Controlled airspace (Instrument / Visual): Controlled airspace within which only IFR and controlled VFR flights are permitted.

Controlled airspace (Visual exempted): Controlled airspace within which both IFR and VFR flights are permitted, but VFR flight are not subject to control.
