Principles observed 1.1 To achieve the uniformity in regulations which is necessary for the safety of navigation of civil aircraft due regard shall be given to the following principles when developing procedures and administrative directives: a) interception of civil aircraft will be undertaken only as a last resort; b) if undertaken, an interception will be limited to determining the identity of the aircraft, unless it is necessary to return the aircraft to its planned track, direct it beyond the boundaries of national airspace, guide it away from a prohibited, restricted or danger area or instruct it to effect a landing at a designated aerodrome; c) practice interception of civil aircraft will not be undertaken; d) navigational guidance and related information will be given to an intercepted aircraft by radiotelephony, whenever radio contact can be established; and e) in the case where an intercepted civil aircraft is required to land in the territory overflown, the aerodrome designated for the landing is to be suitable for the safe landing of the aircraft type concerned. Note. — In the unanimous adoption by the 25th Session(Extraordinary) of the ICAO Assembly on 10 May 1984 of Article 3 bis to the Convention on International Civil Aviation, Contracting States have recognized that “every State must refrain from resorting to the use of weapons against civil aircraft in flight”. 1.2 A standard method shall be established for the manoeuvring of aircraft intercepting a civil aircraft. Such method shall be designed to avoid any hazard for the intercepted aircraft. 1.3 Provision shall be made for the use of secondary surveillance radar or ADS-B, where available, to identify civil aircraft in areas where they may be subject to interception. 2. Action by intercepted aircraft 2.1 An aircraft which is intercepted by another aircraft shall immediately: a) follow the instructions given by the intercepting aircraft, interpreting and responding to visual signals in accordance with the specifications in Appendix 1; b) notify, if possible, the appropriate air traffic services unit; 58CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 c) attempt to establish radio communication with the intercepting aircraft or with the appropriate intercept control unit, by making a general call on the emergency frequency 121.5 MHz, giving the identity of the intercepted aircraft and the nature of the flight; and if no contact has been established and if practicable, repeating this call on the emergency frequency 243 MHz; d) if equipped with SSR transponder, select Mode A, Code 7700, unless otherwise instructed by the appropriate air traffic services unit. e) if equipped with ADS-B or ADS-C, select the appropriate emergency functionality, if available, unless otherwise instructed by the appropriate air traffic services unit. 2.2 If any instructions received by radio from any sources conflict with those given by the intercepting aircraft by visual signals, the intercepted aircraft shall request immediate clarification while continuing to comply with the visual instructions given by the intercepting aircraft. 2.3 If any instructions received by radio from any sources conflict with those given by the intercepting aircraft by radio, the intercepted aircraft shall request immediate clarification while continuing to comply with the radio instructions given by the intercepting aircraft. 3. Radio communication during interception If radio contact is established during interception but communication in a common language is not possible, attempts shall be made to convey instructions, acknowledgement of instructions and essential information by using the phrases and pronunciations in Table A2-1 and transmitting each phrase twice. 59CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 APPENDIX 3 TABLE OF CRUSING LEVELS The cruising levels to be observed when so required by this CAR are as follows: RVSM – FEET a) in areas where feet are used for altitude and where, in accordance with regional air navigation agreements, a vertical separation minimum of 1 000 ft is applied between FL 290 and FL 410 inclusive:* 60CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 61CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 non-RVSM – FEET 62CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 Non-RVSM – METRES 63CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 APPENDIX 4 INTENTIONALLY LEFT BLANK 64CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 APPENDIX 5 UNMANNED FREE BALLOONS (Note.— See Para 3.1.10 of the CAR) 1. Classification of unmanned free balloons Unmanned free balloons shall be classified as: a) light: an unmanned free balloon which carries a payload of one or more packages with a combined mass of less than 4 kg, unless qualifying as a heavy balloon in accordance with c) 2), 3) or 4) below; or b) medium: an unmanned free balloon which carries a payload of two or more packages with a combined mass of 4 kg or more, but less than 6 kg, unless qualifying as a heavy balloon in accordance with c) 2), 3) or 4) below; or c) heavy: an unmanned free balloon which carries a payload which: 1) has a combined mass of 6 kg or more; or 2) includes a package of 3 kg or more; or 3) includes a package of 2 kg or more with an area density of more than 13 g per square centimetre; or 4) uses a rope or other device for suspension of the payload that requires an impact force of 230 N or more to separate the suspended payload from the balloon. Note 1.— The area density referred to in c) 3) is determined by dividing the total mass in grams of the payload package by the area in square centimeters of its smallest surface. Note 2.— See Figure 4.1. 2. General operating rules 2.1 An unmanned free balloon shall not be operated without appropriate authorization from the State from which the launch is made. 2.2 An unmanned free balloon, other than a light balloon used exclusively for meteorological purposes and operated in the manner prescribed by the appropriate authority, shall not be operated across the territory of another State without appropriate authorization from the other State concerned. 2.3 The authorization referred to in 2.2 shall be obtained prior to the launching of the balloon if there is reasonable expectation, when planning the operation, that the balloon may drift into airspace over the territory of another State. Such authorization may be obtained for a series of balloon flights or for a particular type of recurring flight, e.g. atmospheric research balloon flights. 65CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 2.4 An unmanned free balloon shall be operated in accordance with conditions specified by the State of Registry and the State(s) expected to be overflown. 2.5 An unmanned free balloon shall not be operated in such a manner that impact of the balloon, or any part thereof, including its payload, with the surface of the earth, creates a hazard to persons or property not associated with the operation. 2.6 A heavy unmanned free balloon shall not be operated over the high seas without prior co-ordination with the appropriate ATS authority. 3. Operating limitations and equipment requirements 3.1 A heavy unmanned free balloon shall not be operated without authorization from the appropriate ATS authority at or through any level below 18 000 m (60 000 ft) pressure altitude at which: a) there are clouds or obscuring phenomena of more than four octas coverage; or b) the horizontal visibility is less than 8 km. 3.2 A heavy or medium unmanned free balloon shall not be released in a manner that will cause it to fly lower than 300 m (1 000 ft) over the congested areas of cities, towns or settlements or an open-air assembly of persons not associated with the operation. 3.3 A heavy unmanned free balloon shall not be operated unless: a) it is equipped with at least two payload flight termination devices or systems, whether automatic or operated by tele-command, that operate independently of each other; b) for polyethylene zero-pressure balloons, at least two methods, systems, devices, or combinations thereof, that function independently of each other are employed for terminating the flight of the balloon envelope; Note.— Super pressure balloons do not require these devices as they quickly rise after payload discharge and burst without the need for a device or system designed to puncture the balloon envelope. In this context a super pressure balloon is a simple non-extensible envelope capable of withstanding a differential of pressure, higher inside than out. It is inflated so that the smaller night-time pressure of the gas still fully extends the envelope. Such a super pressure balloon will keep essentially constant level until too much gas diffuses out of it. 66CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 c) the balloon envelope is equipped with either a radar reflective device(s) or radar reflective material that will present an echo to surface radar operating in the 200 MHz to 2 700 MHz frequency range, and/or the balloon is equipped with such other devices as will permit continuous tracking by the operator beyond the range of ground-based radar. 3.4 A heavy unmanned free balloon shall not be operated under the following conditions: a) in an area where ground-based SSR equipment is in use, unless it is equipped with a secondary surveillance radar transponder, with pressure-altitude reporting capability, which is continuously operating on an assigned code, or which can be turned on when necessary by the tracking station; or b) in an area where ground-based ADS-B equipment is in use, unless it is equipped with an ADS-B transmitter, with pressure-altitude reporting capability, which is continuously operating or which can be turned on when necessary by the tracking station. 3.5 An unmanned free balloon that is equipped with a trailing antenna that requires a force of more than 230 N to break it at any point, shall not be operated unless the antenna has coloured pennants or streamers that are attached at not more than 15 m intervals. 3.6 A heavy unmanned free balloon shall not be operated below 18 000 m (60 000 ft) pressure-altitude between sunset and sunrise or such other period between sunset and sunrise (corrected to the altitude of operation) as may be prescribed by the appropriate ATS authority, unless the balloon and its attachments and payload, whether or not they become separated during the operation, are lighted. 3.7 A heavy unmanned free balloon that is equipped with a suspension device (other than a highly conspicuously coloured open parachute) more than 15 m long, shall not be operated between sunrise and sunset below 18 000 m (60 000 ft) pressure- altitude unless the suspension device is coloured in alternate bands of high conspicuity colours or has coloured pennants attached. 4. Termination The operator of a heavy unmanned free balloon shall activate the appropriate termination devices required by 3.3 a) and b) above: a) when it becomes known that weather conditions are less than those prescribed for the operation; b) if a malfunction or any other reason makes further operation hazardous to air traffic or to persons or property on the surface; or c) prior to unauthorized entry into the airspace over another State’s territory. 5. Flight notification 5.1 Pre-flight notification 67CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 5.1.1 Early notification of the intended flight of an unmanned free balloon in the medium or heavy category, shall be made to the appropriate air traffic services unit not less than seven days before the date of the intended flight. 5.1.2 Notification of the intended flight shall include such of the following information as may be required by the appropriate air traffic services unit: a) balloon flight identification or project code name; b) balloon classification and description; c) SSR code, aircraft address or NDB frequency as applicable; d) operator’s name and telephone number; e) launch site; f) estimated time of launch (or time of commencement and completion of multiple launches); g) number of balloons to be launched and the scheduled interval between launches (if multiple launches); h) expected direction of ascent; i) cruising level(s) (pressure-altitude); j) the estimated elapsed time to pass 18 000 m (60 000 ft) pressure-altitude or to reach cruising level if at or below 18 000 m (60 000 ft), together with the estimated location; Note.— If the operation consists of continuous launchings, the time to be included is the estimated time at which the first and the last in the series will reach the appropriate level (e.g. 122136Z-130330Z). k) the estimated date and time of termination of the flight and the planned location of the impact/recovery area. In the case of balloons carrying out flights of long duration, as a result of which the date and time of termination of the flight and the location of impact cannot be forecast with accuracy, the term “long duration” shall be used. Note.— If there is to be more than one location of impact/recovery, each location is to be listed together with the appropriate estimated time of impact. If there is to be a series of continuous impacts, the time to be included is the estimated time of the first and the last in the series (e.g. 070330Z-072300Z). 5.1.3 Any changes in the pre-launch information notified in accordance with 5.1.2 above shall be forwarded to the air traffic services unit concerned not less than 6 hours before the estimated time of launch, or in the case of solar or cosmic disturbance investigations involving a critical time element, not less than 30 minutes before the estimated time of the commencement of the operation. 5.2 Notification of launch 68CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 Immediately after a medium or heavy unmanned free balloon is launched the operator shall notify the appropriate air traffic services unit of the following: a) balloon flight identification; b) launch site; c) actual time of launch; d) estimated time at which 18 000 m (60 000 ft) pressure altitude will be passed, or the estimated time at which the cruising level will be reached if at or below 18 000 m (60 000 ft), and the estimated location; and e) any changes to the information previously notified in accordance with 5.1.2 g) and h). 5.3 Notification of cancellation The operator shall notify the appropriate air traffic services unit immediately it is known that the intended flight of a medium or heavy unmanned free balloon, previously notified in accordance with 5.1, has been cancelled. 6. Position recording and reports 6.1 The operator of a heavy unmanned free balloon operating at or below 18 000 m (60 000 ft) pressure-altitude shall monitor the flight path of the balloon and forward reports of the balloon’s position as requested by air traffic services. Unless air traffic services require reports of the balloon’s position at more frequent intervals, the operator shall record the position every 2 hours. 6.2 The operator of a heavy unmanned free balloon operating above 18 000 m (60 000 ft) pressure-altitude shall monitor the flight progress of the balloon and forward reports of the balloon’s position as requested by air traffic services. Unless air traffic services require reports of the balloon’s position at more frequent intervals, the operator shall record the position every 24 hours. 6.3 If a position cannot be recorded in accordance with 6.1 and 6.2, the operator shall immediately notify the appropriate air traffic services unit. This notification shall include the last recorded position. The appropriate air traffic services unit shall be notified immediately when tracking of the balloon is re- established. 6.4 One hour before the beginning of planned descent of a heavy unmanned free balloon, the operator shall forward to the appropriate ATS unit the following information regarding the balloon: a) the current geographical position; b) the current level (pressure-altitude); c) the forecast time of penetration of 18 000 m (60 000 ft) pressure-altitude, if applicable; d) the forecast time and location of ground impact. 69CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 6.5 The operator of a heavy or medium unmanned free balloon shall notify the appropriate air traffic services unit when the operation is ended. 70CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 APPENDIX 6 LIGHTS TO BE DISPLAYED BY AEROPLANE (Note.— See Para 3.2.3 and 3.2.6.2) LIGHTS TO BE DISPLAYED BY AEROPLANES 1.

Horizontal plane. The plane containing the longitudinal axis and perpendicular to the plane of symmetry of the aeroplane. Longitudinal axis of the aeroplane. A selected axis parallel to the direction of flight at a normal cruising speed, and passing through the centre of gravity of the aeroplane. Making way. An aeroplane on the surface of the water is “making way” when it is under way and has a velocity relative to the water. Under command. An aeroplane on the surface of the water is “under command” when it is able to execute manoeuvres as required by the International Regulations for Preventing Collisions at Sea for the purpose of avoiding other vessels. Under way. An aeroplane on the surface of the water is “under way” when it is not aground or moored to the ground or to any fixed object on the land or in the water. 71CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 Vertical planes.

Lights to be displayed on the water 3.1 General Note.— The lights specified herein are intended to meet the requirements of Annex 2 for lights to be displayed by aeroplanes on the water. The International Regulations for Preventing Collisions at Sea require different lights to be displayed in each of the following circumstances: a) when under way; b) when towing another vessel or aeroplane; c) when being towed; d) when not under command and not making way; e) when making way but not under command; f) when at anchor; g) when aground. The lights required by aeroplanes in each case are described below. 72CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 3.2 When under way As illustrated in Figure 2, the following appearing as steady unobstructed lights: a) a red light projected above and below the horizontal through angle of coverage L; b) a green light projected above and below the horizontal through angle of coverage R; c) a white light projected above and below the horizontal through angle of coverage A; and d) a white light projected through angle of coverage F. The lights described in 3.2 a), b) and c) should be visible at a distance of at least 3.7 km (2 NM). The light described in 3.2 d) should be visible at a distance of 9.3 km (5 NM) when fitted to an aeroplane of 20 m or more in length or visible at a distance of 5.6 km (3 NM) when fitted to an aeroplane of less than 20 m in length. 3.3 When towing another vessel or aeroplane As illustrated in Figure 3, the following appearing as steady, unobstructed lights: a) the lights described in 3.2; b) a second light having the same characteristics as the light described in 3.2 d) and mounted in a vertical line at least 2 m above or below it; and c) a yellow light having otherwise the same characteristics as the light described in 3.2 c) and mounted in a vertical line at least 2 m above it. 73CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 3.4 When being towed The lights described in 3.2 a), b) and c) appearing as steady, unobstructed lights. 3.5 When not under command and not making way As illustrated in Figure 4, two steady red lights placed where they can best be seen, one vertically over the other and not less than 1 m apart, and of such a character as to be visible all around the horizon at a distance of at least 3.7 km (2 NM). 3.6 When making way but not under command As illustrated in Figure 5, the lights described in 3.5 plus the lights described in 3.2 a), b) and c). Note.— The display of lights prescribed in 3.5 and 3.6 is to be taken by other aircraft as signals that the aeroplane showing them is not under command and cannot therefore get out of the way. They are not signals of aeroplanes in distress and requiring assistance. 3.7 When at anchor a) If less than 50 m in length, where it can best be seen, a steady white light (Figure 6), visible all around the horizon at a distance of at least 3.7 km (2 NM). 74CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 b) If 50 m or more in length, where they can best be seen, a steady white forward light and a steady white rear light (Figure 7) both visible all around the horizon at a distance of at least 5.6 km (3 NM). c) If 50 m or more in span a steady white light on each side (Figures 8 and 9) to indicate the maximum span and visible, so far as practicable, all around the horizon at a distance of at least 1.9 km (1 NM). 3.8 When aground The lights prescribed in 3.7 and in addition two steady red lights in vertical line, at least 1 m apart so placed as to be visible all around the horizon. 75CIVIL AVIATION REQUIREMENTS SECTION 9 SERIES ‘C’ PART I 8TH JANUARY 2010 ATTACHMENT A UNLAWFUL INTERFERENCE 1. General The following procedures are intended as guidance for use by aircraft when unlawful interference occurs and the aircraft is unable to notify an ATS unit of this fact. 2. Procedures 2.1 If the pilot-in-command cannot proceed to an aerodrome in accordance with the rules in 3.7.2, he/she should attempt to continue flying on the assigned track and at the assigned cruising level at least until able to notify an ATS unit or until within radar or ADS-B coverage. 2.2 When an aircraft subjected to an act of unlawful interference must depart from its assigned track or its assigned cruising level without being able to make radiotelephony contact with ATS, the pilot-in-command should, whenever possible: a) attempt to broadcast warnings on the VHF channel in use or the VHF emergency frequency, and other appropriate channels, unless considerations aboard the aircraft dictate otherwise. Other equipment such as on-board transponders and data links should also be used when it is advantageous to do so and circumstances permit; and b) proceed in accordance with applicable special procedures for in-flight contingencies, where such procedures have been established and promulgated in the Regional Supplementary Procedures (Doc 7030); or c) if no applicable regional procedures have been established, proceed at a level which differs from the cruising levels normally used for IFR flight by: 1) 150 m (500 ft) in an area where a vertical separation minimum of 300 m (1 000 ft) is applied; or 2) 300 m (1 000 ft) in an area where a vertical separation minimum of 600 m (2 000 ft) is applied. Note.— Action to be taken by an aircraft which is intercepted while being subject to an act of unlawful interference is prescribed in 3.8 of this CAR. — END — 76
