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? $\endgroup$ – fooot Jan 29 '18 at 18:16
  • $\begingroup$ You may try to search in IATA statistics like these ones $\endgroup$ – mins Jan 29 '18 at 19:38
  • $\begingroup$ @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... $\endgroup$ – Penguin Jan 30 '18 at 11:15
  • $\begingroup$ Hi @fooot. I believe the comment above answers without being an opinion, and uses a reference, what do you think? Regards $\endgroup$ – Penguin Jan 30 '18 at 11:19
  • $\begingroup$ @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. $\endgroup$ – fooot Jan 30 '18 at 17:57
