Charlie_01 Posted December 28, 2011 Posted December 28, 2011 I've noticed a loss of power above 12-15.000 ft. I know it's usual, especially on slow planes at full payload, but I would knowjust one thing: is there some switch or something else I can do to get power boost, just like water injection on some WW II planes?
Charlie_01 Posted December 28, 2011 Author Posted December 28, 2011 Sorry I've gone wrong: I mean instead something like riching mixture as on prop planes.
Jona33 Posted December 28, 2011 Posted December 28, 2011 Nope, your engines should be running up to 40,000 though. This is weird. Always remember. I don't have a clue what I'm doing
Tailgate Posted December 30, 2011 Posted December 30, 2011 Maybe a dumb question but are your boost pumps on?
mnrty Posted December 30, 2011 Posted December 30, 2011 Are you playing in SIM or GAME mode ? If you are playing in GAME mode your aircaft will fall down at 16.000 :(
GGTharos Posted December 30, 2011 Posted December 30, 2011 What do you mean by loss of power? If you mean you can't maneuver as much, that's normal. If your engines are shutting down, that's not normal. [sIGPIC][/sIGPIC] Reminder: SAM = Speed Bump :D I used to play flight sims like you, but then I took a slammer to the knee - Yoda
Charlie_01 Posted January 7, 2012 Author Posted January 7, 2012 What I mean is that over 12.000 ft. max fuel flow decrease significatively: from 35 pph at SL, 25-30 pph at 6-8000 ft going up to no more than 25 over 12.000. The same for fan's RPM and IAS. Obviously mach number still increase instead, but this mainly happens since sound speed decrease at high altitude, so at same speed corresponding higher mach number and at same IAS corresponding higher ground speed. On internal combustion engine planes you can compensate a lot make mixture more rich, so I want to know if there is similar on a low powered jet as the Hog is.
Eddie Posted January 7, 2012 Posted January 7, 2012 No. This is how it's meant to happen. The fuel flow etc for engines on modern jet aircraft is all managed by computers to ensure they always operate at their best. Lower fuel consumption is the reason why jets fly high, the higher the altitude the more efficient then engines are. Yes you will also see a reduction in thrust.
