This is an excerpt from a report made in Aviation Safety Reporting System. The story is written by the pilot, not by FAA or NTSB officials. Many details, such as the model of the aircraft or the airport, are often removed from the reports to preserve anonymity.
I was the third plane to land on runway XX in a row. I dropped my friend off and drove back to Runway XX.
There was a Citation jet taking off from Runway XX. The Cessna 310 and the plane were talking, saying they saw each other.
310 declared downwind for runway YY, but I was thinking XX since everyone else was using that runway.
I looked at my traffic display and saw that the 310 looked like it was in the wind for XX (actually it was on base for YY). I looked up ultimate and base for XX and it was clear. I announced departure XX and took off. Someone called a bypass three times loudly and quickly.
I looked to the left and saw the 310. He turned left and I turned right to clear. If he had just landed, I would have flown over him.
This was my closest call in many years of flying. The pilot of 310 was unaware that other aircraft were using the XX except the jet.
My main mistake was expecting the 310 to use runway XX like all the other planes.
ZZZ had become so busy that the tower would not have allowed this ridiculous miss.
The main problem: the human factor
