I know there are a lot of statistics about how many planes are in the air on average, but not all aircraft flying are turbine-driven. How may turbojet, turbofan, and turboprop aircraft, on average, are in the air at any given moment?

    $\begingroup$ It may be impossible to answer as many smaller aircraft may not be tracked or recorded. How precise does the number have to be? $\endgroup$

  • $\begingroup$ @user39178 Right now, Flightradar24 is tracking 10,582: flightradar24.com/37.46,126.44/14 Are they all turbine powered? Probably. Are they every turbine powered aircraft? Probably not. But I don't know where you will get a better answer than that... $\endgroup$

  • $\begingroup$ @Penguin most of the traffic is turbine powered, but definitely not all. And it probably doesn't include everything. But you're right that it's probably a good guess. $\endgroup$
