ENR 1.8   ATM CONTINGENCY PLAN FOR ASECNA AIRSPACES UNDER ACC OF DAKAR TERRESTRIAL, DAKAR OCEANIC,BAMAKO, OUAGADOUGOU, NIAMEY, ABIDJAN AND LOME

1.	OBJECTIVES
	1.1	This contingency plan contains procedures to ensure the provision of air navigation services in the event of simultaneous disruption of Air traffic services provisions within airspaces under the responsibility of Dakar Terrestrial, Dakar Oceanic, Bamako, Ouagadougou, Niamey, Abidjan and Lomé ACCs
	1.2	The contingency plan is designed to accommodate the flow of international air traffic with a minimum of disturbance for aircraft transiting the contingency airspace only.
2.	CENTRAL COORDINATING COMMITTEE
	The Central Coordinating Committee (CCC) function shall be to oversee the implementation of the Contingency Plan and if the Air Traffic Services (ATS) is disrupted for an extended period, make arrangements for and facilitate the temporary relocation of the Air Traffic Services to ACC that will be in charge of information and alert services and the restoration of Air Traffic Services in coordination with the WACAF Contingency Coordination Team and adjacent FIRs.

3.	AIR TRAFFIC MANAGEMENT AND CONTINGENCY PROCEDURES
	3.1	AIR TRAFFIC SERVICES RESPONSIBILITIES
		ASECNA contingency routes (ACR) and ASECNA oceanic contingency routes (AOCR) are designed to maximize the use of existing ATS route structures and communications, navigation and surveillance services. The assigned flight levels on contingency routes contained in the tables in appendix are conform to semi-circular rules and shall be maintained during the transit into the airspace of contingency. NDJAMENA ACC will provide information and alert services only for aircraft on ATS contingency routes in Niamey FIR. NOUAKCHOTT ACC will provide information and alert services only for aircraft on ATS contingency routes in Dakar FIR and Lomé UTA. Transfer of responsibilities in Dakar Oceanic FIR still comply with EUR/SAM and AORRA contingency provisions as per ASECNA AIP 13ENR1.8-11 and 13ENR1.8-12. In the event of activation of the current contingency plan, ASECNA shall publish not less than 48 hours before, the corresponding NOTAM indicating the following:       a) Time and date of the beginning of the contingency measure.       b) Any other details with respect to the disruption and actions being taken that aircraft operators may find useful.
	3.2	SEPARATION
		Separation criteria shall be applied in accordance with the Procedures for Air Navigation Services-Air Traffic Management (Doc 4444) and the Regional Supplementary Procedures (Doc7030).
		Vertical separations are applied on the contingency routes for aircraft maintaining the same cruising flight level
		Longitudinal separation of twenty (20) minutes, must be applied by the adjacent ACC before entering the airspace of disruption. Cruising speed limitations shall be applied during transit.
	3.3	AIRSPACE CLASSIFICATIONS
		Airspace classification will be changed in class G
	3.4	AIRCRAFT POSITION REPORTING
		When CPDLC has been authorized for use by the relevant ATC authority this will become a means of communication in addition to HF.
		Traffic Information Broadcast by Aircraft (TIBA) procedures shall apply in the contingency airspace during periods of contingency
		TIBA frequencies shall be as follows: AFI REGION – 126.9 MHz
	3.5	PROCEDURES FOR ATS UNITS
		a) During the period the contingency procedures are in effect, flight plans and other aircraft movement messages must continue to be transmitted by operators via the AFTN/AMHS using normal procedures;
		b) Aircraft operators should file flight plans using contingency routes listed in the tables in appendix : Note : ATS routes not included in the table below are temporarily unavailable
		c) The ACC responsible for aircraft entering the contingency airspace will instruct pilots to maintain the last flight level assigned and speed (Mach number if applicable) while transiting;
		d) The ACC responsible for aircraft entering the contingency airspace will not authorize any change in route, flight level or speed
		e) The ACC in charge of aircraft entering the contingency airspace will inform crew member that they must establish contact with the first ATS Unit after transiting the contingency airspace not less than 10 minutes before the estimated time of entry to the NEXT CONTROLLED AIRSPACE.
	3.6	OTHER MEASURES
		Other measures related to the disruption of air traffic services and the implementation of the contingency scheme within the contingency airspace may be taken as follows :       • Delay or suspension of general aviation IFR operations; and       • Delay or suspension of commercial IFR operations
4.	PILOT AND OPERATOR PROCEDURES
	4.1	OVERFLIGHT ARRANGEMENTS
		During the period of activation of this Contingency Plan the adjacent ACC will provide normal ATC clearances for aircraft to enter the contingency airspace. The adjacent ACC is not responsible for coordination or provision of overflight clearances. As in normal procedure, operators must overflight and landing permissions for concerned airspaces.
	4.2	PILOTS OPERATING PROCEDURES
		All aircraft transiting through the contingency airspace shall strictly comply with the following
			a)	Maintain contact with ACC in charge of information and alert according to the tables in appendix;
			b)	Operate along or as close as possible to the centerline of the assigned contingency air traffic route.
			c)	Reach the flight level assigned by adjacent ACC for the transit at least ten (10) minutes before entering the contingency airspace.
			d)	Maintain the flight level assigned by the last adjacent ACC while operating within the contingency airspace, unless an emergency or flight safety reason exists.
			e)	Maintain a continuous listening watch on the VHF frequency 126.9 MHz, and transmit blind in English on 126.9 MHz position reports five (5) minutes before and overhead each compulsory reporting point established along the respective air traffic route.
			f)	Include in the last position report to the competent adjacent ACC the estimated time of arrival over the entry and exit points of the contingency airspace.
			g)	Whenever emergencies and/or flight safety reasons make it impossible to maintain the flight level assigned for the transit, climb or descend well to the right of the centerline of the air traffic route being flown but remaining within the contingency airspace, and to inform immediately, by blind broadcast on the VHF frequency 126.9 MHz, all other aircraft likely to be affected by transmitting a relevant emergency level change message (comprising the aircraft call-sign, the aircraft position, the flight levels being left and crossed, etc.).
			h)	Contact the competent adjacent ACC as soon as possible and at least ten (10) minutes before the estimated time of arrival over the relevant exit point of contingency airspace to obtain clearance for entering the adjacent airspace concerned.
			i)	Display navigation and anti-collision lights always during the transit of contingency airspace.
			j)	The application of SLOP is strongly encouraged
			k)	Transponders should be set on a discrete code assigned by ATC or select code A2000 if ATC has not assigned a code
	5.	COMMUNICATIONS PROCEDURES
		5.1. DEGRADATION OF COMMUNICATION -PILOT RADIO PROCEDURES.
			a)	When operating within the contingency airspace, pilots should use normal radio communication procedures
			b)	In the absence of communication with ATC, the pilot should continue to make routine position reports on the assigned frequency and also broadcast positions in accordance with the TIBA procedures.
	6. SEARCH AND RESCUE
		a) ACCs involved in this contingency plan are required to assist any distressed aircraft of which they are aware.
		b) The center that receives a distress message from an aircraft shall send the necessary messages (INCERFA, ALERFA or DETRESFA) to all authorities in the SAR service involved in this plan including the SAR authority of the center which is in contingency situation.
		c) Each SAR authority shall assist as necessary its neighbor as requested in their LoA.
	7. IMPLEMENTATION OF THE PLAN TESTING AND REVIEW
		a) The plan shall be tested by ATC simulation at least once per year. b) A full review shall be conducted at least once per three years
	8. IMPLEMENTATION OF THE PLAN
		The provisions of this contingency plan shall be promulgated by NOTAM to be issued by ASECNA in coordination with ICAO and the concerned States.
