Central Africa Overfly: Sahel Conflicts & ATC Gaps
Last updated: April 2026
Route Overview
The Central Africa overfly corridor carries Europe-to-Southern Africa traffic across the Sahel belt — the semi-arid region stretching from Senegal to Sudan that has become one of the world's most active conflict zones. Flights from Paris, London, Amsterdam, and Frankfurt to Johannesburg, Cape Town, Luanda, and other southern African destinations historically route through West and Central African airspace, crossing multiple FIRs managed by ASECNA (Agency for Aerial Navigation Safety in Africa and Madagascar) and national providers.
The corridor crosses a region where multiple non-state insurgencies operate simultaneously. Mali, Burkina Faso, and Niger — all governed by post-transition administrations following political transitions between 2020 and 2023 — face ongoing non-state armed group activity. Chad and northern Cameroon contend with armed-group remnants in their northern regions. The Central African Republic remains in a protracted internal conflict. None of these situations directly target aviation at cruising altitude, but the degraded state infrastructure — including ATC — is a direct consequence of prolonged instability.
For airlines, the primary concern is not surface-to-air threats (non-state groups lack anti-aircraft capability beyond man-portable systems effective to roughly FL150) but rather the absence of reliable air traffic services across vast portions of the route. Several FIRs in the region have no radar coverage, limited HF radio reliability, and procedural control only — meaning aircraft are separated by time and position reports rather than active surveillance.
FIRs Crossed
Well-equipped ATC with radar coverage. Standard transit for southbound European traffic. Morocco and Tunisia provide reliable services.
ASECNA-managed but with minimal radar. HF radio communications are unreliable in parts of the FIR. Active non-state armed-group operations on the ground. French military withdrawal completed 2023. Post-transition administration since July 2023. Procedural control only above FL245.
Nigeria provides better ATC infrastructure than Sahel neighbors, with radar coverage around major cities. However, northern sectors near the Niger/Chad border have limited surveillance. Non-state armed-group activity reported in Borno State. Lagos ACC manages southern transits competently.
One of Africa's largest FIRs by area with among the least infrastructure. No radar coverage. HF communications only. ASECNA manages but staffing is minimal. Political instability following the 2021 leadership transition. Flights transit at high altitude on procedural separation.
ASECNA-managed with partial radar. Anglophone crisis in western regions but does not affect overflights. Northern sectors border the N'Djamena FIR with similar limitations. Douala ACC provides reasonable service for transit traffic.
Key Risks
ATC Infrastructure Gaps
The most significant operational risk in this corridor is not conflict but the absence of modern ATC infrastructure. Several FIRs — particularly N'Djamena (FTTT), Niamey (DRRR), and portions of Kano (DNKK) — rely entirely on procedural control. Aircraft are separated by position reports via HF radio, which is frequently unreliable due to atmospheric conditions. ICAO has repeatedly flagged these deficiencies. ASECNA has modernization plans but implementation has been slow, hampered by political instability in member states. The practical consequence: pilots may go 30-60 minutes between confirmed position reports, and ATC has no independent means to verify aircraft location.
Sahel Conflict Belt
The Sahel non-state insurgencies do not currently pose a direct threat to aircraft at cruising altitude. Reported capability for the involved armed groups is limited to small arms and man-portable systems with maximum effective ceilings of approximately FL100–FL150, well below commercial transit altitudes. However, the situation has degraded state capacity to maintain aviation infrastructure, train ATC personnel, and fund ASECNA contributions. Additionally, military operations in the region create unpublished temporary flight restrictions that are not always communicated to ASECNA or ICAO.
Diversion Airport Scarcity
Suitable diversion airports in the Sahel are rare. N'Djamena, Niamey, Ouagadougou, and Bamako have adequate runways but may lack fuel, ground handling, or customs/immigration for international diversions. Security conditions at some airports are uncertain — Bamako and Ouagadougou have experienced attacks near airport perimeters. Medical and firefighting capabilities are limited. Airlines operating through this corridor must carry additional contingency fuel, and some carriers plan diversions to coastal West African airports (Accra, Lagos, Abidjan) even when these are significantly farther.
Alternative Routing
Route via Morocco, Senegal (Dakar Oceanic), Ghana (Accra FIR), Nigeria (Lagos), and then south through Gabon/Congo. Adds 1-2 hours but provides radar coverage through better-equipped coastal FIRs. Used by Air France, KLM, and British Airways for some Southern Africa services. Accra FIR (DGAC) has modern radar and reliable communications.
Ethiopian Airlines and South African Airways route Europe-Southern Africa traffic via Cairo, Khartoum/Addis Ababa, and then south through the East African FIRs (Nairobi, Dar es Salaam). Avoids the Sahel entirely. Longer for Western European origins but provides continuous radar coverage through better-maintained ATC systems. Preferred by carriers with East African hubs.
Airlines & Operators
Air France historically dominates Europe-West Africa traffic due to France's colonial legacy and continues to operate extensive services to Abidjan, Douala, Brazzaville, and Kinshasa that transit Central African airspace. KLM, Brussels Airlines, and TAP Air Portugal also serve multiple West and Central African destinations. These carriers have extensive operational experience in the region and maintain dedicated procedures for Sahel transit.
Ethiopian Airlines routes Europe-bound traffic via its Addis Ababa hub using the eastern corridor. South African Airways and Kenya Airways similarly use eastern routing. For Europe-to-Johannesburg direct services, carriers make a routing decision: Air France and British Airways often use coastal West African routing, while Lufthansa has used more direct Sahel transit routes. ASKY Airlines (Togo-based, Ethiopian Airlines subsidiary) operates regional services within West Africa that transit the corridor at lower altitudes.
Insurance Considerations
Central African overfly does not currently attract war risk insurance surcharges comparable to Middle Eastern conflict zones, as the surface threats do not reach cruising altitude. However, insurers increasingly factor ATC reliability into their risk models. Some underwriters apply modest surcharges for operations requiring extended periods without radar surveillance — not for conflict risk but for the increased probability of mid-air incidents, CFIT (controlled flight into terrain), or delayed emergency response in areas with no ATC coverage. The operational insurance distinction between "conflict zone" and "infrastructure-deficient zone" is becoming a significant factor in route economics.
