Nigerian Airspace Management Agency (NAMA) says safety reporting is as important as investing in safety critical equipment and manpower training, because incident reports were a critical and strategic aspect of the aviation safety chain.
The Acting Managing Director of NAMA, Mr. Matthew Lawrence Pwajok who made this known at an event in Lagos also urged pilots, air traffic controllers, airlines, ground handlers, passengers and other stakeholders in the aviation industry to continue to report aviation incidents to the safety authorities as this would further enhance the relative safety in the industry and also boost confidence in air travel.
He said,”if you don’t report incidents we can’t control them, if we don’t have reports we cannot provide the required risk analysis and mitigations.”
He commended pilots for being very faithful in incident reporting, even to the detriment of the airlines, stating that this could sometimes cause slight flight delays while awaiting a review or investigation of the incident by NCAA before releasing the aircraft back for operations.
“When these incidents are reported by pilots to ATC, they are immediately relayed to NCAA for investigation, and when the reported event or defect is mitigated, the aircraft is released back to service.
“For instance, we had an occurrence at Escravos yesterday that was reported to the control tower by the pilot, and consequently NAMA informed AIB and NCAA, and after the required mitigations were effected, the aircraft was released back to service. It is as prompt as that!
“These are the kind of 24/7 collaboration,
cooperation, and coordination that have largely enhanced safety in the sector.” he said.
The NAMA boss appreciated stakeholders in the industry for the enhanced safety in the
sector which he attributed to the effective synergy amongst stakeholders and strategic efforts by service providers.
He opined that the relative safety enjoyed in the sector over the last 10 years was not by chance or luck but as a result of significant investments both in infrastructural deployment and human capital development to enhance safety in the Nigerian airspace, thereby ensuring that major air disasters such as those
witnessed between 2005 and 2006 were a thing of the past.
Pwajok said, “one of the first things the agency did under the Obasanjo government was the implementation of Safe Tower project and this began with the automation of the control tower at Abuja airport in 2007. In 2008 we completed that of Lagos and Port Harcourt and subsequently Kano. This project provided the main mitigation to what was considered the primary cause of most of these air disasters.
“The project provided NAMA with automated air traffic management systems, as well as meteorological sensors along the runways and provided ATC with real time weather information from the runways, availing us with wind direction, wind speed, low level wind shear alerting systems, cloud altitudes, cloud densities, cloud direction of movement, air temperature, air pressure, prevailing weather conditions, etc. Thus, basically every element of weather is displayed at the control tower at the four major airports, so pilots are given adequate information on approaching weather, prevailing weather or forecasted weather conditions.”
“We went further to deploy the Total Radar Coverage of Nigeria (TRACON) in 2010. We
could now track aircraft over the entire airspace of Nigeria and beyond, unlike before when air traffic controllers had to manually depend on pilot reports to control and ensure safety of flights, separation of aircraft from each other, sequencing them for arrival or for takeoff.
The radar system has the capacity to detect conflicts, aircraft crossing each other, with inbuilt ground safety nets such as short-term conflict alert, medium term
conflict detection with respect to aircraft crossing at the same level or in close proximity either vertically or laterally, the radar system will alert ATC. The radar system is also equipped with minimum safe altitude warning, thus if you are very low to the terrain it will alert us. The system also has danger area infringement warning to alert aircraft away from restricted, prohibited or danger areas with known or reported activities hazardous to air safety. These are all ground safety nets, about ten of them that are in-built in the radar system to give the air traffic controller adequate information, and to a large extent, that has enhanced safety in our airspace.”
Pwajok further stated that the drive towards enhancing air safety is attributable to global, regional and national initiatives following the development of the ICAO Global Air Navigation Plan, Global Aviation Safety Plan and the Global Aviation Safety Plan in 2012.
At the regional level, the ministers responsible for civil aviation in African met in Abuja, Nigeria following the ranking of Africa as the continent with the least volume of flight operations, but with the highest fatal accidents rate in the world.
“Thus on 20th July 2012, we had the ministerial declaration in Abuja: what the International Civil Aviation Organization (ICAO) refers to as the Abuja Safety Targets. Ministers responsible for
aviation met in Abuja, reviewed the safety level in Africa and agreed that over 60% of the fatal accidents were caused by (i) loss of control in flight (ii) controlled flight into terrain and (iii) runway incursion, excursion and confusion.
In addressing these, the Ministerial Conference and the African Civil Aviation Commission (AFCAC) came up with a 16-point agenda out of that declaration: to reduce loss of controlled flight into terrain by 50%; reduce runway incursion and excursion by 50%; reduce loss of control in flight by 50%, implement state safety programme by CAAs and also ensure effective implementation of oversight, Pwajok said.”
He noted that the above strategies were domesticated at national levels, while strategic and concerted efforts were made towards implementation and enhancement of air safety through investment in safety critical infrastructure, training, establishment of safety management system and quality management system, as well as development of safety
plans, safety policies, safety objectives, safety key performance indicators, and acceptable level of safety performance.
