DOC 7030 part 1

Reference Procedure

1.1 Visual Flight Rules (VFR)

(Annex 2 - 4.6)

VFR flights to be operated within a control zone established at an aerodrome serving International Flights and in specific portions of the associated terminal control area shall:

  1. have two - way radio communications;

  2. obtain clearance from the appropriate air traffic control unit; and

  3. report position as required

Note: The phrase "specified portions of the associated terminal control area" is intended to signify at least those portions of the TMA used by International IFR Flights in association with approach, holding, departure and noise abatement procedures. Instrument Flight Rules (IFR)

(Annex 2 - 2.2. and Chapter 5)

Flights shall be conducted in accordance with the Instrument Flight Rules (even when not operating in instrument meteorological conditions) when operated:

  1. more than 100 NM seaward from the shoreline within controlled airspace; or

  2. at or above Flight Level 150

3.0 A / G communications and in - flight reporting

(ANNEX 2 -3 6.3, 3.6.5, and 5.3.3 and PANS ATM / 501 Chapter 4, 4 - 11)

All aircraft on VFR flights, and aircraft on IFR flights outside controlled airspace, shall maintain a watch on a radio station furnishing communications for the unit providing flight information service in the flight information region and file with that station information as their position unless otherwise authorized by the State overflown.

Reference Procedure The aircraft call sign / identification shall be transmitted immediately before or after the word "position". The position of the aircraft shall be transmitted in reference to a reporting point name, name code designator or, if not named:

  1. for flights operating in a predominantly east - west direction:

    1. latitude in degrees and minutes; and

    2. longitude in degrees only;

  2. for flights operating in a predominantly north - south direction:

    1. latitude in degrees only; and

    2. longitude in degrees and minutes. The time at which the aircraft is over the reporting point shall be transmitted in four digits, giving both the hour and the minutes. The altitude / flight level of the aircraft shall be included in the position report. Next position and time shall normally be expressed as the reporting point name, name - code designator or latitude and longitude as indicated in Estimated time over the next position shall be expressed in four digits. Ensuing position information shall include the name, name - code designator or coordinates of the next succeeding reporting point, whether compulsary or not.

4.0 Special Procedures for in - flight contingencies

General Procedures

The following general procedures apply to both subsonic and supersonic aircraft

4.2.1 If an aircraft is unable to continue flight in accordance with its Air Traffic Control Clearance, a revised Clearance shall be obtained at the earliest possible time and, in the meantime, the aircraft shall broadcast position (including ATS route designator or the track code, as appropriate) and intentions, on frequency 121.500 MHZ at suitable intervals until Air Traffic Control Clearance is received.

12.1.1 Alerting and Search and Rescue Services - Routes and equipment of Private Aircraft

Annex 6 - part II - 6.3 and 6.4):

General Aviation aircraft operating over designated areas, land or sea, where search and rescue operations would be difficult, should:

  1. carry appropriate survival equipment;

  2. follow the routes or specified procedures if not equipped with two - way radio except that under special circumstances, the appropriate authority may grant specific exemptions from this requirement.
