Human Factors; Procedure
This was a frightening misjudgment by controller.[I] arrived at ZZZ [in a] C310. My recollection of communications with Tower may be incorrect.[Runway] XX was the active. One (or maybe two) aircraft were ahead of me and requested [Runway] XY. As I am based at [an FBO]; I too requested [Runway] XY. I entered downwind and was cleared to land. On final; I observed an airliner taking off from [Runway] XX. Initially [I] thought to go around; but [I] was well above the jet as it took off. It was evident I could safely land on [Runway] XY. Then; Tower ordered me to go around; which I did.I was cleared to land and did so without any problem. I asked Tower why the conflict and was told I was too fast. In any case; regardless of airspeed; the controller must have been fully informed. [The controller] told me I was doing 150 [knots]. I doubt that as I do short final at 100 [knots]. While I name [the controller]; I mean no criticism. She was very professional and helpful.Bottom line; fast or not; I find it incomprehensible the controller could clear me to land [Runway] XY and the airliner to takeoff [Runway] XX. As the airliner was on the ground; there could not have been urgency. Takeoff clearance could have been delayed 3 minutes with no significant effect.My suspicion is that the Tower Controller was new and inexperienced.
Reporter was unable to obtain any further information from the Tower personnel.
Cessna 310 pilot reported a NMAC after ATC cleared the pilot to land and then directed a missed approach after clearing another aircraft for takeoff.
