Nairobi Wilson airport reportedly one of the busiest airports in Africa. As I got within range I called on the radio to ask for joining instructions. They had helicopters coming in and had aircraft arriving and departing from two different runways, what could go wrong ! I mentioned over the radio early on that I was not familiar with the airfield, I knew I had to look for a monastery and a racecourse to report at but couldn’t see them anywhere. I did however manage to spot what I thought was the airport in the distance. They cleared me left base and asked me to report finals 07 number two. As I tracked down finals I looked ahead to try and see the other aircraft. I spotted it and could see it was a Cessna caravan and I was starting to catch it. I called the tower and explained there was insufficient separation between myself and the other aircraft and asked if I should go around, he replied no please continue. I wasn’t sure if he had heard me correctly but then noticed the aircraft in front going around. A great experience to land at such a busy airport.
