The Commissioner of
Accident Investigation Bureau and Prevention (AIBP), Captain Usman Muktar, has disclosed that Wind Shear was responsible for the Sosoliso, ADC, Bellview and other accident that happened in 2005 and 2006 aside human error.
Wind shear is a different wind speed and direction over a relatively short distance in the atmosphere which could spin an aircraft out of control.
Experts say it is dangerous for flights because it is highly turbulent and according to them, the only way to prevent wind shear is to avoid it.
The AIBP commissioner disclosed that during the investigations on the causes of the accidents, it was found that weather played key role in downing the aircraft which together killed over 400 people, while further investigation however narrowed the cause of accidents down to wind shear.
“I will like us to cast our minds to 2005, when we had the Bellview accident in October 22,2005. In November, the same year we had a small aircraft that went down in Kaduna and killed two people. On December 10, the same year, Sosoliso went down in Port Harcourt and in 2006, October 29, the ADC went down”, Muktar said.
The commissioner said all these accidents have some form of weather-related factors and we narrowed the weather-related to wind shear activities.
He explained that the stop wind shear related accidents, AIBP made recommendations in the accident reports and directed that there should be regulatory changes, training changes, including airborne equipment (aircraft).
“We recommended that all pilots should be retrained both at initial level and the level of currency because pilots are expected to do recurrency training recognition and recovery from wind shear phenomenon”, he stated.
According to him, that was taken into Nigerian regulation and it is being monitored to meet requirement that certain categories of aircraft most have onboard a wind shear alerting system, which is predictive, that is, it should be able to see ahead and tell the pilot to avoid it because the best solution is avoidance.
He said the meteorlogical agency installed at the aircrafts low level Wind Shear alerting system, which were first installed at the four major airports and later at others.
“I am happy to say that since 2005 and 2006, after those crashes we have not had any other weather related accident in Nigeria” Muktar said.
NAMA Boosting Security Of Nigeria’s Airspace
The Nigerian Airspace Management Agency (NAMA), established via the Act of Parliament, has the mandate to provide safe, efficient, effective and economic air navigation services to airspace users, through deployment of new technologies and dedicated workforce.
The vision is for NAMA to be one of the leading Air Navigation Service Providers (ANSP) in the w
NAMA’s Acting Managing Director,orld.
Mr Mathew Pwajok, said the agency had initiated relevant projects to enable it live up to expectation.
He spoke recently when he featured at the News Agency of Nigeria (NAN) Forum in Abuja.
Pwajok said the government was ready to install Category 3 Instrument Landing System (ISL) in three international airports in the country.
He listed the airports as: Malam Aminu Kano International Airport, Kano, Port Harcourt International Airport and the Katsina Airport, bringing airports with Category 3 ILS to five.
According to him, ILS is a navigational equipment that provides lateral guidance for an aircraft, sky guidance for the aircraft and the longitudinal guidance for the aircraft when landing.
“Navigational facility is one of the very critical requirements for access into an airport safely, efficiently and economically. We place very high premium on the procurement and installation of navigational equipment.
“Over the past five years, we have deployed significantly a large number of navigational equipment. I can go through some of them by justifying my statement.
“Currently, we have installed what we call Category 3 Instrument Landing System (ILS) at Lagos and Abuja airports.
“We are also planning to install addition ones in Kano, Port Harcourt and Katsina.”
The NAMA chief, who explained that Category 3 landing system was the highest category for landing anywhere in the world, said that government was set to invest heavily to ensure that all the nation’s international airports had the facility.
Pwajok said that lighting system would complement Category 3.
He said that Category 3 approach system was also required to guide pilots, using the instrument landing system.
“Currently, we have installed instrument landing system of Category 2 that requires what we call low visibility operations.
“In operations, where the visibility is below 800m and not lower than 300m, we use what we call a Category 2 instrument landing system.
“For a Category 1 instrument landing system, which are few, you need 800m visibility or more.
“That is to say, visibility must be about 1km (1,000m) for you to be able to do a Catigory1 landing system, the lowest of the three categories.
“For Category 3, when the aircraft and the flight crew are adequately certified for it, with the visual lighting system available, you can basically land in zero visibility, “he said.
Pwajok said that Category 2 ILS was installed in Sokoto, Kano, Minna, Kaduna, Maiduguri, Yola, Jos, Enugu and Benin airports.
He said that Category 2 ILS was currently being installed in Ilorin, Ibadan and Akure airports, noting that some state airports such as Gombe, Kebbi, Bayelsa and Anambra had already installed Category 2 ILS facilities.
The NAMA boss explained that the airport at Lafia in Nasarawa State, which also had Category 2 ILS had not been opened to services because it had not yet been inaugurated.
Pwajok said that Categroy1 facilities were still being used in few airports, pointing out that government had planned to replace them with Category 2 ILS.
“We have other equipment that can guide airplanes to airports and we call them Very High Frequency Omni-Directional Range (VOR), a ground-based electronic system that provides information for high and low altitude routes and airport approaches.
“The VOR is like a broadcast station. It transmits information. Unlike radio station where you tune and hear music, for this navigational facility, when you tune, it gives you directional guidance.
“It directs you for example, if you are going to Lagos, it shows you where the direction to Lagos is. So you fly on that flight path.
“It will also give you the distance to where you are going as well as distance from where you are coming from,” Pwajok said.
The NAMA boss further said the agency was currently upgrading control towers in four international airports to enhance air traffic management.
Pwajok said that the control towers, installed over 10 years ago, were obsolete and as such needed to be upgraded.
“On our project, we currently have a safe tower project. In 2005/2006, we have some air craft crashes.
“In 2007, the Obasanjo government implemented what we called the safe tower, which simply refers to automated air travel management system at the control towers of Lagos, Abuja, Kano and Port Harcourt airports.
“Now, these systems after over 10 years are due for upgrade and currently that is what we are doing to upgrade the control tower at the four international airports- Lagos, Abuja, Kano and Port Harcourt.
“ This is to bring them in line with the right capacity, the right functionality and capability for enhanced air traffic management at these airports,’’ he said.
Pwajok explained that a total raider coverage, that was inaugurated over 10 years ago by then President Goodluck Jonathan also needed an upgrade.
He said the Federal Government approved N28 billion for the upgrade of the Total Radar Coverage of Nigeria (TRACON).
“They are in nine locations – Lagos, Abuja, Kano, Port Harcourt, Ilorin, Obubra in Cross Rivers, Maiduguri, Talata-Mafara in Kebbi and Numan in Adamawa.
“These equipment provide a complete coverage of Nigeria on raider, so aircraft flight within the country are seen and controlled by air traffic controllers in the radar.
“So, the equipment are being upgraded to be in line with global standards and also in line with the expectations of increased traffic volume and requirement for safety and efficiency of flight.
“So this project is currently ongoing and we are doing a survey movement raider and ground control at Lagos and Abuja that will provide surface guidance for aircraft,” he said.
He said once they were upgraded, there would then be a surveillance control from departure gate to arrival gate that would be fully automated.
He added that there would be an automated system that would sequence aircraft on departure, stressing that this would completely reduce delays.
“At the moment what we do is that the air traffic controller uses his judgment to determine which aircraft comes first.
“But automated system will detect the speed of an aircraft, the performance and the direction the aircraft is coming from and will now have an air traffic controller to sequence them on arrival.
“We are implementing that in Lagos and Abuja, and hopefully by this year, this project will be completed as it is one of our key projects,’’ he added.
Pwajok said the country currently has 13 modernised and automated control tower projects to enhance air traffic control at the airports, adding that similar projects had been completed in Zaria and Kastina states.
He said that the control towers had been integrated with metrological data, where regular weather reports would be brought into the system.
On navigation, he said the agency had deployed a very High Frequency Omni-directional radio-range (VOR) Doppler that would guide aircraft, either over flying on airspace or flying from one airport to the other.
He said that this equipment had replaced initial landing system instrument, adding that the satellite navigation system that gives precision on aeronautical management had been deployed.
According to him, Very Small Aperture Terminal (VSAT) have been installed in 26 locations – 24 in airports, one in NAMA and one in NEMA headquarters to facilitate search and rescue.
According to him, this VSAT will provide digital exchange of information at a very high speed and voice exchange of information using ground radius and air ground communication between air traffic controllers and pilots.
He said if fully completed, it would enhance air ground communication, ground to ground communication and electronic management of information of flight movement.
The NAMA boss assured that the agency would do all within its powers to boost air safety in Nigeria.
