Aviation Height Clearance: Why Nigeria Must Preserve Distinction Between Regulation, Service Provision

The Nigerian aviation industry is grappling with a proposed amendment to its revenue-sharing formula, sparking debate over the Nigerian Airspace Management Agency's (NAMA) bid for a larger slice of the existing five percent Ticket, Charter and Cargo Sales Charge (TCSC).

Beyond the revenue-sharing aspect, NAMA has put forth a significant proposal: to classify obstacle evaluation and Aviation Height Clearance (AHC) as technical services. Under this proposal, NAMA would retain 90 percent of the associated fees, leaving only 10 percent for the Nigeria Civil Aviation Authority (NCAA). While NAMA's role in specialized functions like designing flight procedures, conducting surveys, and assessing obstacles is undeniable, the core of the debate lies in governance, not just funding.

The article stresses that Aviation Height Clearance is far more than a simple permit for constructing tall structures. It is framed as a critical preventive safety mechanism within Nigeria's aviation system. Its primary objective is to ensure that no construction project compromises air navigation safety or the integrity of Nigerian airspace. The process involves rigorous regulatory oversight, including thorough evaluations against Obstacle Limitation Surfaces, verification of technical data, and site inspections, culminating in the issuance of clearance only after extensive scrutiny.
