Dr Abdullahi Musa, the Director, Public Affairs and Consumer Protection of Nigerian Airspace Management Agency (NAMA) has debunked claims that the state of air navigation safety and the serviceability of landing facilities across Nigerian airports are not reliable, saying the Nigerian airspace is not only safe, but also professionally managed and aligned with global best practices.
Abdullahi who reacted to a publication through a signed press release maintained that their
infrastructure undergoes periodic ground and airborne verification to ensure operational accuracy, signal integrity, and safety reliability.
The release titled
“Harmattan Operations and Air Safety In Nigeria: Setting the Record Straight” said the
recent publication by a national newspaper which, while highlighting the perennial challenges of Harmattan weather, advanced claims that could mislead the public regarding the state of air navigation safety and the serviceability of landing facilities across Nigerian airports.
According to Dr. Abudllahi, despite seasonal meteorological conditions are a legitimate subject of public discourse, it is essential that such discussions are anchored in technical accuracy, regulatory context, and an informed understanding of how aviation safety systems function.
“Unfortunately, some of the assertions made in the referenced report risk creating unnecessary public anxiety by conflating weather-induced operational limitations with alleged infrastructure inadequacies.
“NAMA therefore considers it necessary, in the overriding interest of public confidence and factual clarity, to place the following facts on record.
“Contrary to insinuations that Nigeria’s landing facilities are poorly maintained or unfit for Harmattan operations, NAMA states unequivocally that all navigational aids (NAVAIDs) at Federal Government airports are routinely maintained, flight-checked, and calibrated in strict compliance with International Civil Aviation Organization Standards and Recommended Practices (SARPs) and the Nigerian Civil Aviation Regulations (Nig CARs)”.
Continuing, Dr Abdullahi said, “These processes are not discretionary. They are mandatory safety requirements, conducted using NAMA’s dedicated flight inspection and calibration aircraft, operated by highly trained technical and flight inspection personnel. Equipment such as Instrument Landing Systems (ILS), VHF Omnidirectional Range (VOR), Distance Measuring Equipment (DME), and other CNS/ATM infrastructure undergo periodic ground and airborne verification to ensure operational accuracy, signal integrity, and safety reliability.
“Furthermore, all such activities are carried out under continuous regulatory oversight by the Nigerian Civil Aviation Authority (NCAA), which audits compliance, validates calibration cycles, and enforces corrective actions where necessary.In line with global best practices, NAMA does not operate in opacity”.
Clarifying further, Dr. Abdullahi said, “The status of navigational aids nationwide is formally published through Aeronautical Information Publications (AIP) Supplements, accessible to airlines, pilots, operators, and international stakeholders.Specifically, AIP Supplement S81/2025 dated 9 October 2025 comprehensively documented the calibration and serviceability status of all NAVAIDs in Nigeria.
“At the time of publication, only the ILS facilities at Maiduguri, Ilorin, Owerri, Zaria, Minna, and Calabar were approaching due calibration dates, while all other systems nationwide remained within valid inspection periods
“Subsequently, in December 2025, NAMA conducted a nationwide round of flight calibration exercises, restoring serviceability timelines across multiple locations. As a result of this proactive intervention, the ILS facilities currently due for calibration are limited to Katsina, Jos, Ilorin, Yola, and Owerri—a normal occurrence within cyclical inspection regimes, not evidence of system failure or neglect.
“One of the more persistent misconceptions in public commentary relates to the assumption that CAT III Instrument Landing Systems must be deployed at all airports to guarantee safety, particularly during Harmattan.
“This view is technically inaccurate and inconsistent with global aviation practice. The deployment of ILS CAT I, CAT II, or CAT III is determined by operational need, traffic volume, aircraft equipage, airline capability, and long-term meteorological data—not by prestige, optics, or public perception.
“Globally, many highly efficient international airports operate safely and successfully with CAT I or CAT II systems, because prevailing weather conditions do not justify the complexity, cost, and operational demands of CAT III infrastructure. Nigeria is no exception.
“Historical meteorological data across Nigerian airports show that the least average runway visibility recorded during Harmattan conditions is approximately 150 metres. In response to this operational reality, NAMA has designed, validated, and published instrument approach procedures aligned with ILS CAT II minima, which adequately support safe aircraft operations even during the most challenging seasonal conditions typically experienced in the country”.
Abdullahi therefore maintained that, to suggest that the absence of widespread CAT III systems equates to compromised safety is therefore misleading, adsing aviation safety is determined by appropriateness and reliability, not by deploying the highest available technology where it is operationally unjustified.
“Nigeria’s airports where ILS CAT II procedures are published are fully capable of supporting safe operations within approved minima, subject to airline and aircraft capability. Where systems are temporarily withdrawn, downgraded, or restricted, such actions are taken proactively and conservatively, in the interest of safety—not as evidence of regulatory failure.
“Harmattan-related delays, diversions, or cancellations are primarily a function of weather conditions, airline operational decisions, and aircraft capability, rather than neglect or breakdown of navigational aids’
He further affirmed that weather is an external variable that no aviation authority can eliminate; therefore, it can only be managed through accurate forecasting, conservative decision-making, and adherence to established minima.
‘In this regard, NAMA works closely with the Nigerian Meteorological Agency (NiMet) to ensure continuous dissemination of accurate and timely weather information, while providing real-time air traffic management support throughout the Harmattan period.
The Nigerian airspace is safe, professionally managed, and aligned with global best practice. While Harmattan weather presents operational challenges, it does not imply infrastructural failure or diminished safety standards.
