Gulf Air L1011 crews were in 1976 the second airline in the world ( trained by BA ) in low vis take offs and landings plus ground manoeuvring.All the above procedures utilised the onboard ground run monitor and ground speed indicator.Low vis chart distances were inserted into the ground run monitor and a 3 knot ground speed and ground radar instructions were to be the way to go to and from the runway in low vis.
Sadly it not work that well because the ground radar was not then up to the guidance job in the turns.
When landing in low vis at LHR I was guided in by an Indian gentleman standing in the back of a Mini truck shinning a powerful beam of light on the nose cone...
this system worked and could be immediately introduced at airports where lighting and guidance are inadequate....I recommend my Indian gentleman and his light be considered by this African airports management team who will probably state that safety is their first priority but not really mean it.
