Yola Airport has deteriorated night landing facilities. The Runway lighting system had a system of being problematic. Due to numerous safety reports by crews, the system is NOTAMed U/S and the airport is now limited to daylight operations. Of course, in typical Nigerian style some crews will sneak in "after hours".
The same situation exists in Benin and Calabar. The runway lighting upgrade in Owerri has been going on for years, in fact it has been 90 % complete for years so its still limited to daylight
. The lights in Ilorin are also horendous.
Also a lot of airports have deteriorated lighting conditions due to overgrown grass, its not unusual for runway lights to disappear in the flare. Also in some airports the light can be so dim that the surrounding lighting is much brighter.
