Something about Flying and Targeting

[Taysiir 10]

Did a search for a similar thread, maybe I didn't search hard enough, but I couldn't find anything that answered my question:

When flying in a single-seat airplane, how do you cycle through targets like you would when ordering your co-pilot to, when flying in a multi-seat air vehicle? And I'm talking about targeting vehicles, or other air planes. :s

It's the "next target" keybind. Mine is altered, dunno default, sorry.
