- Watch the video and see how the horizon is set across his window - once there, he keeps it there.
- Watch how he keeps looking further round the turn.
- He has a Co Pilot to watch outside and listen too.
- He has also got an FE to watch anything inside.
- He briefed the turn when he saw the light aircraft ahead of him - so they had time to check for traffic.
- From the start of the video and awareness of the other a/c, to starting the turn is about 23 seconds.
- So no one was taken by surprise.
Consider that, at some small African stopping points, you have to buzz the tower to let them know you have arrived as their radio is u/s. In some places when there is a war, the 'tower' decamps to the tallest hotel building in town and you buzz THAT.
I am not a pilot in Africa but my nephew is.
