Pilots shall also maintain a listening watch on HF frequencies 11300, 5517 and 8879 by day and in addition, frequency 5634 by night; b) To include in their last position report to the competent adjacent ACCs of the Seychelles FIR the estimated time over the entry and exit points of the Seychelles FIR; c) To reach the appropriate flight level assigned by the competent adjacent ACCs of the Seychelles FIR at least 10 minutes before entering the Seychelles FIR; d) Maintain during their entire flight time within the Seychelles FIR, the last flight level assigned to them by the competent adjacent ACC and in no way change the assigned flight level, including Mach Number, where assigned, except in cases of emergencies or for reasons of flight safety; e) Report their positions when over compulsory reporting points for the ATS contingency route being flown; Seychelles Aeronautical Information Services AIP SUP 02/09 Page 5 of 9
f) Operate along or as close as possible to the centerline of the assigned ATS contingency route; g) To display navigation and anti-collision lights at all times during their transit through the Seychelles FIR; h) To maintain their own longitudinal separation of 20 minutes from preceding aircraft operating at the same cruising level on the same ATS contingency route; i) To contact the next adjacent competent ACC as least 10 minutes before the estimated time of arrival over the relevant exit point of the Seychelles FIR; j) Whenever an emergency or flight safety reasons make it impossible for an aircraft to maintain the last flight level assigned for the transit through the Seychelles FIR, it shall descend or climb well to the right of the centerline of the contingency ATS route being flown, but remaining within the Seychelles FIR and inform other aircraft being affected by the descent by broadcasting an emergency level change message on the IFBP VHF frequency 126.9 Mhz and emergency frequency 121.5 Mhz. The message shall contain the aircraft callsign, aircraft position, flight level being vacated or crossed and new intended flight level; k) Inform the next adjacent ACC of the level change by using the appropriate VHF or HF radio frequencies. 8.0 IATA In-flight Broadcast Procedures (IFBP) AFI Region 8.1 Listening Watch A listening watch should be maintained on frequencies 126.9 Mhz at least 10 minutes before entering the Seychelles FIR and until leaving this airspace. For aircraft taking off from any aerodrome located within the lateral limits of the Seychelles FIR, listening watch should start as soon as the aircraft is airborne and shall be maintained until leaving the Seychelles FIR. 8.2 Time of Broadcast A broadcast shall be made in English:- a) 10 minutes before entering the Seychelles FIR or, for a pilot taking off from an aerodrome located within the lateral limits of Seychelles FIR, as soon as appropriate; b) 10 minutes prior to crossing over a reporting point for the ATS contingency route being flown; c) 10 minutes prior to crossing or joining an ATS route; d) at 20 minute intervals between distant reporting points; e) 2 to 5 minutes, where possible, before a change in flight level; f) at a time of a change in flight level; and g) at any other time considered necessary by the pilot; h) In the interest of reducing congestion on the IFBP frequency, pilots may exercise discretion to omit closely spaced repetitive IFBP reports.

8.3 Operating Procedures 8.3.1 Change of cruising level 8.3.1.1 Changes of cruising level are considered necessary by pilots to avoid traffic conflicts, for weather avoidance or other valid operational reasons, including reasons; 8.3.1.2 When cruising level changes are unavoidable, all available aircraft lighting which will improve visual detection of the aircraft should be displayed while changing levels. 8.4 Collision Avoidance If on receipt of a traffic information broadcast from another aircraft, a pilot decides that immediate action is necessary to avoid an imminent collision risk to his aircraft and this cannot be achieved in accordance with the right-of-way provisions of Annex 2, he should; a) unless an alternative maneuver appears more appropriate, descend immediately 500 feet ; b) if aircraft is TCAS equipped, follow the advisory instructions as provided by the system; c) display all available aircraft lighting which would improve the visual detection of the aircraft; d) as soon as possible reply to the broadcast advising action being taken; e) notify the action taken on the appropriate ATS frequency; and f) as soon as the situation has been rectified, resume normal flight level, notifying the action on the appropriate ATS frequency. 8.5 Normal Position Reporting Normal position reporting procedures should continue at all times, regardless of any action taken to initiate or acknowledge a traffic information broadcast. 8.6 Operation of transponders Pilots should ensure that transponder procedures as contained in ICAO PANS OPS, Doc 8168, are complied with and in the absence of other directions from ATC, operate their transponders on Mode A and C, Code 2000. 8.7 Use of TCAS TCAS equipped aircraft should have TA/RA mode selected at maximum range. 9.0 The IFBP in AFI In many FIRs in the AFI Region, communications both fixed and mobile have either not been implemented or operate well below the required reliability. This has impact on the proper Seychelles Aeronautical Information Services AIP SUP 02/09 Page 7 of 9
provision of Air Traffic Services, especially flight information service. Consequently, the AFI Regional Technical Conference has decided that the IATA In-Flight Broadcast Procedure (IFBP) should be used within designated FIRs in the region as an interim measure until such time as communications affecting the FIRs in question have been improved. 10.0 Designated Frequency in AFI In the AFI Region, and in Seychelles FIR, the designated frequency for the IFBP is 126.9 Mhz. 11.0 Enforcement 11.1 All airlines operating in the AFI Region and particularly in Seychelles Flight Information Region are requested to: a) ensure that their air crews are fully briefed on these procedures and area of application described; b) ensure that their charts and flight documentation are fully amended to reflect the foregoing; 11.2 Any operator reported to IATA as not applying the procedure shall be contacted immediately, informed of the procedure and requested to apply it. 11.3 Attention is drawn to the fact that during the Haj Pilgrimage period the number of east-west flights in the north central part of the AFI Region increases dramatically and with the risk of ATS incidents and thus, the importance of the In-Flight Broadcast Procedure. 12.0 Review The procedure and its area of applicability shall be reviewed by the AFI Regional Coordination Group from time to time and FIRs in which the procedure is to be applied may be added or excluded as necessary. 13.0 Distribution This contingency plan is distributed to all Seychelles AIP subscribers, ICAO, IATA and Jeppesen.
