What is a typical altitude for a dogfight?
At what altitude(s) do dogfights typically occur?


All of them.

Throughout history dogfights have generally started at one of the aircraft's "best altitude", which depends on the aircraft, and then descended as the pilot's trade altitude for airspeed.

Altitude disparity can be so great that one or the other will simply not engage, or do so at a serious penalty if they are forced to. This occurred during the Falklands when the Argentinian aircraft had much more performance than the UK's Harriers, but only at higher altitudes. The Harriers simply refused to fight them, so if the Argentines wanted to get to the ships they had to fly down where the Harriers had the advantage. The same occurred during WWII when US B-17's flew at altitudes where German fighters were struggling, allowing the escorting P-51's to chew them up.

It is not uncommon for extended dogfights to end with troops on the ground shooting down some of the aircraft, as was the case with the Red Baron (or so the Australians will claim).
