There he would call, 'Downwind', to which the tower would reply, 'Pancake', signifying 'Clear to land'. The pilot would begin descending then from a thousand feet and turn to face the runway in use, guided by a 'funnel' of lights leading to the flarepath itself. Lastly he would watch for a green light from the airfield controller, who was positioned in a van beside the runway and had an uninterrupted view of runway activity.
This differs slighly from what I understand with the Drem lighting system which is what Charlwood was describing. The last call would be
" Funnels" and I undesratnd this is where our final call evolved from-any comments anyone?
