The Federal Government says it is ready to install a Category 3 Instrument Landing System (ISL) at Malam Aminu Kano International Airport, Kano, Port Harcourt International Airport and Katsina Airport.
Mr. Mathew Pwajok, Acting Director General of the Nigerian Airspace Management Agency (NAMA), made the announcement on Sunday in Abuja, when he attended the News Agency of Nigeria (NAN) forum. ).
Pwajok said the move would bring the number of airports with Category 3 ISL in the country to five.
According to him, the instrument landing system is a navigation equipment that provides lateral guidance for an aircraft, sky guidance for the aircraft, and longitudinal guidance for the aircraft when arriving at the landing.
“The navigation facility is one of the most critical requirements for accessing an airport safely, efficiently and economically. We attach great importance to the purchase and installation of navigation equipment.

“Over the past five years, we have deployed a significant amount of navigation equipment. I can review some of them justifying my statement.
“Currently we have installed what we call a Category 3 Instrument Landing System (ILS) at Lagos and Abuja airports.
“We also plan to install more in Kano, Port Harcourt and Katsina.”
The NAMA chief, who explained that the Category 3 landing system was the highest category for landing anywhere in the world, said the government was set to invest heavily to ensure that all international airports in the country had the facility.
Pwajok said the lighting system would complete Category 3.
He said the Category 3 approach system was also needed to guide pilots, using the instrument landing system.
“Currently we have installed a Category 2 Instrument Landing System which requires what we call low visibility operations.
“In operations, where the visibility is less than 800 meters and not less than 300 meters, we use what we call a Category 2 Instrument Landing System.

“For a Category 1 instrument landing system, of which there are few, you need visibility of 800 meters or more.
“That is, visibility needs to be around 1km (1000m) for you to make a Category 1 landing system, the lowest of the three categories.
“For Category 3, when the aircraft and the flight crew are properly certified for it, with the visual lighting system available, you can essentially land in zero visibility,” he said.
Pwajok said Category 2 ILS has been installed at Sokoto, Kano, Minna, Kaduna, Maiduguri, Yola, Jos, Enugu and Benin airports.
He said Category 2 ILS was currently installed at Ilorin, Ibadan and Akure airports, noting that some state airports such as Gombe, Kebbi, Bayelsa and Anambra had already installed ILS facilities. of category 2.
The NAMA boss explained that the Lafia i Nasarawa state airport, which also has a Category 2 ILS, had not been opened for services as it had not yet been commissioned .
Pwajok said Category 1 facilities were still in use at a few airports, pointing out that the government had plans to replace them with Category 2 ILS.

“We have other equipment that can guide planes to airports and we call it the Very High Frequency (VOR) Omnidirectional Range, an electronic ground system that provides information about high and low altitude routes and approaches. airports.
“VOR is like a broadcast station. It transmits information. Unlike the radio station where you tune in and listen to music. For this navigation facility, when you tune in, it gives you directional guidance.
“It directs you for example, if you go to Lagos, it shows you where the direction to Lagos is. So you are flying on this flight path.
“It will also give you the distance to where you are going as well as the distance from where you came from,” Pwajok said. (NOPE)
