Ikeja - The Nigerian Airspace Management Agency (NAMA) in Lagos said on Sunday that it spent at least N200 million annually on the calibration of navigational equipment in all the airports across the country.
NAMA's Managing Director, Nnamdi Udoh, disclosed this in a statement signed by Supo Atobatele, General Manager, Public Affairs, and obtained by the News Agency of Nigeria (NAN).
He said the ongoing exercise which started at the weekend in Lagos with the routine calibration of the two Instruments for Landing Systems (ILS) would last two weeks.
Udoh named the ILS as the Very High Omni-directional Radio Range/Distance Measuring Equipment (VOR/DME) and the Path Approach Precision Indicator (PAPI), all at the Murtala Muhammed International Airport, Lagos.
"The calibrated equipment are the recently installed ILS/DME, Conventional Omni-Directional Radio Frequency (CVOR)/DME at Enugu, Makurdi, Uyo, Abuja, Kano, and Port Harcourt airports.
"The newly-installed airfield lighting system at Makurdi will equally be flight-checked by Flight Calibration Services of the UK, using DA42 multi-purpose platform aircraft."
According to the NAMA boss, communication radio coverage check for Lagos and Kano Areas Control Centres will be carried out during the calibration exercise.
Udoh noted that the calibration would ensure that all the navigational aids at the airports and en-route stations were in good shape.
He, therefore, appealed to authorities of the airlines operating in the county to support NAMA's safety drive by settling their outstanding debts.
