Obsolete Radar: Ticking Time Bomb, Govt’s swift intervention

The clock is ticking. The question is: will we fix the radar before the screen goes blank? asks, WOLE SHADARE

For a pilot cruising at 35,000 feet, the silent partnership between the cockpit and the ground is the bedrock of safety. But in Nigeria, that partnership is fraying at the edges. Behind the high-tech jargon and the polished glass of Air Traffic Control (ATC) towers lies a harrowing reality: the Total Radar Coverage of Nigeria (TRACON) is no longer a shield—it is a shadow of its former self.

In the high-stakes world of aviation, obsolete isn’t just a technical term; it’s a ticking time bomb. TRACON is the backbone of the nation’s civil aviation surveillance, but it has reached a critical breaking point.

Solving Nigeria’s radar crisis has transitioned from a routine maintenance schedule into an emergency national security priority.

What was once a flagship multi-billion naira project is now being described by the Managing Director of NAMA, Engr. Farouk Ahmed Umar is a system on the verge of total failure.

FG’s swift intervention

There is a ray of hope, as the Federal Government has swiftly intervened to resolve problems with equipment functionality and other issues affecting air traffic controllers and other workers in the agency.

Umar confirmed that Tinubu has approved the total overhaul and replacement of the nation’s obsolete radar systems.

The scope of presidential intervention includes procurement of modern signal processors and antennas for the nine primary radar sites, including Lagos, Abuja, Kano, and Port Harcourt and a shift away from “working without backup” by installing secondary surveillance systems to eliminate potential blind spots.

The intervention also includes moving from the outdated 2008 architecture toward the more sophisticated platforms adopted by global aviation leaders since 2014.

Umar further stated that the agency is currently in high-stakes discussions with the Original Equipment Manufacturer (OEM), Thales Group of France, to secure a lifeline for the ageing system before the total overhaul of the ageing equipment.

The situation is a classic aviation dilemma: Since 2014, sourcing parts for the TRACON system (deployed between 2008 and 2010) has been a nightmare.

“The President has granted approval to the Minister of Aviation and Aerospace Development, Festus Keyamo, to find a solution to the surveillance system. NAMA is already in talks with the OEM. There is already approval for that”, Umar said.

Ghost in the Machine

When TRACON was commissioned in 2010, it was hailed as the crown jewel of Nigerian aviation. A €66 million investment in partnership with Thales of France, it promised to light up the Nigerian sky, allowing controllers to see every aircraft from Lagos to Maiduguri.

The system was commissioned 16 years ago with an expected lifespan of 10 years. Fast forward to 2026, and the system is gasping for air. The lifespan of such high-tech surveillance equipment is typically 10 years.

Because the technology is legacy, Thales (the French manufacturer) no longer mass-produces many of the essential components. NAMA is currently forced to cannibalise parts from inactive radar heads to keep others spinning.

“The components are becoming obsolete with no spare parts,” warns Engr. Farouk Ahmed Umar, the Managing Director of the Nigerian Airspace Management Agency (NAMA). “Most parts are working without back-up. The airspace is at risk of losing surveillance service.”

What does “losing surveillance” actually look like? It’s not always a total blackout. It’s the dropping of labels—where an aircraft’s digital identity, altitude, and speed disappear from the controller’s screen, leaving only a nameless blip. It’s the frequent system failures due to power fluctuations and the desperate cannibalisation of old parts to keep one radar head spinning.

When the radar fails, the system reverts to procedural separation. This is the aviation equivalent of driving in the dark and shouting your location out the window to avoid other cars. It forces controllers to increase the distance between aircraft, leading to massive flight delays as the highway in the sky narrows, increased fuel burn for airlines forced into holding patterns, and a heightened risk of mid-air collisions, particularly in the busy Lagos-Abuja corridor.

Challenge	Impact on Operations
30% IGR Deduction	The Federal Government’s automatic deduction from NAMA’s revenue is stripping away the “safety-critical” cash needed for a total radar overhaul.
Static Navigation Fees	NAMA is still charging ₦11,000 per flight, a rate fixed in 2008. In 2026, this is commercially unsustainable for maintaining high-tech hardware.
Operational Costs	Massive fuel consumption for power backups and currency fluctuations make buying even “grey market” spare parts nearly impossible.

Financial Stranglehold

The crisis is not just technical; it is fiscal. NAMA is currently battling a perfect storm of economic pressures. The agency’s Internally Generated Revenue (IGR) is being raided by a 30% federal government deduction, leaving little for the multi-billion-naira upgrades required.

This has stripped the agency of the safety-critical funds needed for immediate hardware replacement.

While the 2026 Aviation Budget proposes ₦87.31bn, NAMA’s specific capital allocation (approx. ₦6.3bn) is seen by experts as a drop in the ocean compared to the cost of a total radar overhaul, which requires hundreds of millions of Euros.

Furthermore, the charges for air navigation have remained stagnant at ₦11,000 per flight since 2008. In an era where a spare part for a Thales radar is priced in Euros, and the Naira has faced historic devaluations, the math simply doesn’t add up.

“We are met with blackmail each time we want to increase charges,” Umar lamented during a recent visit by the Permanent Secretary, Ministry of Aviation and Aerospace Development. “But the airport must remain serviceable. We spend a huge amount on fuel to keep these systems running.”

The government has approved the modernisation of TRACON in principle, but funding delays remain the primary obstacle.

Minister of Aviation and Aerospace Development, Festus Keyamo, has prioritised infrastructure renewal, yet the gap between policy approval and hardware on the ground remains the core of the conundrum.

The Cost of Silence

The International Civil Aviation Organisation (ICAO) sets the standards for global air safety. If Nigeria cannot guarantee surveillance, it risks a downgrade that could lead international carriers to avoid its airspace altogether—a move that would cost the economy billions in lost overflight fees and tourism revenue.

While the Federal Government has recently focused on “VPASS” biometric systems for ground security, the industry consensus is clear: you cannot secure an airport if you cannot see the sky.

The Roadmap Forward

The current push by the Ministry of Aviation involves a complete replacement of the fleet of radar sites. NAMA is advocating for exemption from IGR deductions to fund emergency upgrades, a tariff review to align with the 2026 economic reality, and migration to ADS-B: a shift toward Satellite-Based Surveillance (Automatic Dependent Surveillance-Broadcast), the global successor to traditional ground-based radar.

The Verdict

Nigeria’s aviation sector is at a crossroads. The TRACON system, once a source of pride, is now a liability held together by the ingenuity of overstretched engineers and luck.

To prevent the “time bomb” from detonating, the government must move beyond modernisation and commit to a complete replacement of its radar fleet. In the cockpit of a Boeing 737 descending into Lagos, there is no room for error. On the ground, there should be no more room for delay.
