“The effect of the dust and sand stirred by the wind is known as Harmattan Dust Haze.
“Therefore, pilots should note that air-to-ground visibility may be considerably reduced due to the dust haze.
“In addition, aerodrome visibility might fall below the prescribed minima and in severe conditions dust haze can blot out runways, the markers and airfield lightings over wide areas.”
“Hence, all pilots are obliged to exercise maximum restraint especially when severe weather condition is observed or reported by NIMET,” he said.
The NCAA spokesperson advised pilots to obtain adequate departure, en route and destination weather information and briefing from NIMET prior to flight operations at all the airports.
“Operators are therefore advised to ensure necessary measures are put in place to manage the effects of flight delays or cancellations on their passengers.
“All stakeholders are required to ensure strict compliance with this circular,” Adurogboye said.
