Bremspropeller Posted January 30, 2023 Share Posted January 30, 2023 You're pulling up with airbrakes out in partial thrust and then yank back the stick, while firewalling the throttle, provoking a massive compressor-stall, from which you never recover. That's what it seems to be to me. 7 So ein Feuerball, JUNGE! Link to comment Share on other sites More sharing options...
Ebphoto Posted January 31, 2023 Share Posted January 31, 2023 Guilty of doing this as well. The strange thing is you don’t get any feedback or big warning lights etc when it occurs. At least I don’t remember any. You just loose all thrust and go into glider mode. I did happen to restart it by flying down in a steep AOA and it started back up.

ARM505 Posted January 31, 2023 Share Posted January 31, 2023 From the recent patch notes (my bold): Engine: Flying backwards or having significant tail wind with RPM below 7000 might turn the engine off. Moving the throttle to idle before the RPM are above 300 may lead to fire or over-temperature due to accumulation of fuel faster than before (IMPORTANT). Engine stall can now be caused by moving the RPM back and forth too fast or engaging the afterburner at very high AoA or outside the flight envelope. Engine stall RPM oscillations are now less severe. Engine temperature in overspeed corrected to what is indicated in the manuals (<= 735 ºC). Engine starter sound starts 2 seconds earlier than before. Throttle is clickable now near idle detent position. When clicked it is set to idle cut-off position. 1 1 Link to comment Share on other sites More sharing options...

(In that case I understand) Although your aircraft cries at you with warnings and buffeting, you ignore all of it and keep pulling AoA in the red regime. How should it recover? You actually never leveled off. As well. 3 Alias in Discord: Mailman Link to comment Share on other sites More sharing options...
Dragon1-1 Posted January 31, 2023 Share Posted January 31, 2023 Yes, but that doesn't typically indicate an engine problem, it indicates an out of envelope maneuver. People here are used to engines with electronic controls that pretty much don't care what you're doing with your physical throttle control, or how you're flying the ship, since they handle their own fuel and air supply. Even our Tomcat is a version that didn't get that nasty RIO-killing compressor stall anymore. Korean War jets, which do simulate compressor stalls, aren't that popular. The F-1 is actually a lot closer to the F-86D than to Mirage 2000 in that regard. It's a 60s aircraft at heart and as such, and unlike the MiG-19 (which I think is too lenient in many areas), it fully simulates the compressor stall problems common on those aircraft. 1 Link to comment Share on other sites More sharing options...
Joyz Posted January 31, 2023 Share Posted January 31, 2023 Mirage F-1 also called in french as "la fléchette française" it is not designed to have a lot of maneuverability and actualy doesn't like such "immelmann" maneuver. F1 is intended to fly fast in straight, deliver, go back home. It is a typical intercepteur of 60'. Try to fly it as it was intended to be flown. 1 Link to comment Share on other sites More sharing options...

You have to be careful with the throttle when at high AoA, going from idle to AB while having an AoA > 20-25º is very risky. 1 1 Link to comment Share on other sites More sharing options...
