PILOT AND OPERATOR PROCEDURES

8.1

Filing of flight plans

Flight plan requirements detailed in BURKINA FASO AIP continue to be apply during Contingency operations, except where modified by the contingency ATS routes and FLAS specified by ATC and/or in NOTAM.

8.2

Over flight approval

Aircraft operators must obtain over-flight approval from the BURKINA FASO Civil Aviation Authority prior to operating flights through the OUAGADOUGOU UTA. During the period of activation of this Contingency Plan, NIAMEY ACC will provide normal ATC clearances for aircraft to enter the OUAGADOUGOU UTA. NIAMEY ACC is not responsible for coordination or provision of overflight clearances for the OUAGADOUGOU UTA. The operator must ensure any required overflight approval has been obtained.

8.3

Pilots operating procedures

All aircraft transiting through OUAGADOUGOU UTA shall strictly comply with the following:

Maintain contact with NIAMEY ACC according to the paragraph 4 of this contingency plan.

Operate along or as close as possible to the centerline of the assigned contingency air traffic route.

Reach the flight level assigned by the adjacent ACC for the transit of OUAGADOUGOU UTA at least ten (10) minutes before entering OUAGADOUGOU UTA.

Maintain the flight level assigned by the last adjacent ACC while operating within OUAGADOUGOU UTA, unless an emergency or flight safety reason exists.

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.

Include in their last position report to the competent adjacent ACC the estimated time of arrival over the entry and exit points of OUAGADOUGOU UTA.

Whenever emergencies and/or flight safety reasons make it impossible to maintain the flight level assigned for the transit of OUAGADOUGOU UTA, climb or descend well to the right of the centerline of the air traffic route being flown but remaining within OUAGADOUGOU UTA, 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 callsign,
the aircraft position, the flight levels being left and crossed, etc.).

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 OUAGADOUGOU UTA to obtain clearance for entering the adjacent airspace concerned.

Display navigation and anti-collision lights always during the transit of contingency airspace.

The application of SLOP is strongly encouraged

Transponders should be set on a discrete code assigned by ATC or select code A2000 if ATC has not assigned a code.

COMMUNICATION PROCEDURES

8.4

Degradation of Communication - Pilot Radio Procedures

8.4.1

When operating within the contingency airspace, pilots should use normal radio communication procedures. (Where limited or not ATS is available communications will be conducted in accordance with the procedures in the Plan, or s otherwise notified by NOTAM)

8.4.2

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.

PUBLIC HEALTH EMERGENCIES

9.1

The delegated ATS unit, upon receipt of information from a pilot or another ATS unit, regarding suspected case(s) of communicable disease, or other public health risk, on board the aircraft, shall forward a message as soon as possible to the ATS unit serving the destination / departure, unless procedures exist to notify the appropriate authority designated by the State and the aircraft operator
or its designated representative.

9.2

To avoid misunderstanding that may result in inappropriate reaction from the stakeholders including air operators, information provided by the Health Sanitary Board (HSB) should be obtained in written form and relayed to air operators in written form. Where communication means do not enable relay of written text, the information shall be read verbatim.

10.

VOLCANIC ASH CONTINGENCY PLAN (VACP)

10.1

If a volcanic ash cloud is reported or anticipated in OUAGADOUGOU UTA, the delegated ATS unit should take the following actions:

Immediately transmit relevant information to the flight crews of potentially affected aircraft to ensure that they are aware of the current position and expected position of the cloud and the concerned flight levels;

Respond to requests for a course change or a level change as far as possible;

Propose a route change to avoid or leave the reported or predicted areas of presence of the volcanic ash cloud when requested by the pilot or as the controller deems it necessary; and

Where possible, request a special flight report when the flight route enters or anticipates the planned volcanic ash cloud and transmit the report to the appropriate agencies.

10.2

When a flight crew informs the delegated ATS unit that they have inadvertently entered a cloud of volcanic ash, the delegated ATS units should:

Respect measures applicable to an aircraft in an emergency, and;

Alter the assigned route or level only if the pilot requests so or if the airspace or traffic conditions require it.

11.

Interception of civil aircraft

11.1

Pilots need to be aware that in light of current international circumstances, a contingency routing requiring aircraft to operate off of normal traffic flows, could result in an intercept by military aircraft. Aircraft operators must therefore be familiar with international intercept procedures contained in ICAO Annex 2- Rules of the Air, Paragraph 3.8 and Appendix 2, Sections 2 and 3.

11.2

Pilots need to continuously listen out on the VHF emergency frequency 121.5MHz and should operate their transponders always during flight, regardless of whether the aircraft is within or outside airspace where secondary surveillance radar (SSR) is used for ATS purposes. Transponders should be set on a discreet code assigned by ATC or select code A2000 if ATC has not assigned a code.

11.3

If an aircraft is intercepted by another aircraft, the pilot shall immediately:

Follow the instructions given by the intercepting aircraft, interpreting and responding to visual signals in accordance with international procedures;

If possible, notify to ATS Unit;

Set transponder code to A7700, unless otherwise instructed by the appropriate ATS unit;

Attempt to establish radio communication with the intercepting aircraft by making a general call on the emergency frequency 121.5MHz; and

If instructions are received by radio from any source that conflict with those given by the intercepting aircraft, the intercepted aircraft, shall request immediate clarification while continuing to comply with the instructions given by the intercepting aircraft.

12.

SEARCH AND RESCUE

12.1

The delegated ATS unit involved in this contingency plan is required to assist any distressed aircraft of which they are aware and which flies over a contingency space.

12.2

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.

12.3

Each SAR authority shall assist as necessary its neighbor as requested in their LOA.

Contact details of its SAR Authority are provided in paragraph 15.3 below.

13.

PLAN TESTING AND REVIEW

13.1

The Plan shall be tested by ATC simulation at least once per year.

13.2

A full review shall be conducted at least once per three years.

14.

IMPLEMENTATION OF THE PLAN

The provisions of this contingency Plan shall be promulgated by NOTAM to be issued by BURKINA FASO Civil Aviation Authority in coordination with ICAO and the concerned States.
