VFA15-Juliet Posted March 22, 2018 Posted March 22, 2018 (edited) Hi. So manual states that normal FAN indication is 82% at takeoff, mine does not go beyond 74% a max throttle, after this week's update. At idle it shows something like 25% Anyone else ? Edited March 22, 2018 by VFA15-Juliet Details added
mvsgas Posted March 22, 2018 Posted March 22, 2018 Engine RPM (core or fan) will depends on many factors, for example ambient temp. Most engines will have a range rather than a specific number. Many engine do not even bother to tell you the % RPM at high throttle settings ( or Power level angle PLA) so they only tell you;"Do not exceed this" So I don't know if there is a problem or not. To whom it may concern, I am an idiot, unfortunately for the world, I have a internet connection and a fondness for beer....apologies for that. Thank you for you patience. Many people don't want the truth, they want constant reassurance that whatever misconception/fallacies they believe in are true..

Frederf Posted March 22, 2018 Posted March 22, 2018 Version 1.8.5, 1000' check from full power brake release, SL, 15C gives 81% actual virtually unchanged throughout the entire takeoff roll. 82.75% was only achieved in flight above 10,000'. Chart indicates a 82.75% predicted fan speed or slightly over 1.6% under speed which would correspond to a 4% thrust deficiency.
VFA15-Juliet Posted March 22, 2018 Author Posted March 22, 2018 Ok. Thanks. So, if I am reading this correctly 77% Fan rpm is indicative of engine malfunction. I am getting constant 74% at Laughlin (Nevada) with he "Summer, heat" weather preset loaded. My question is, am I just an inexperienced girl who does not get it, or is there something wrong? Funny thing is that it was never like that in 2.2 OA
sobek Posted March 22, 2018 Posted March 22, 2018 Check your throttle axis in game if you are getting full deflection. Good, fast, cheap. Choose any two. Come let's eat grandpa! Use punctuation, save lives!
VFA15-Juliet Posted March 22, 2018 Author Posted March 22, 2018 Sure I did Check your throttle axis in game if you are getting full deflection. Yes, thanks I am 100% sure it is max, even tried with keyboard to make sure.
Frederf Posted March 22, 2018 Posted March 22, 2018 If summer, heat is the same for NTTR as Caucasus then 42C should give nearly 79% (78.7%) with droop and ~80.3% (+1.6%) if droop is minimized by a high power engine run before takeoff. 74% is much lower than the chart predicts, an unacceptable amount which would dictate an aborted takeoff.
toutenglisse Posted March 23, 2018 Posted March 23, 2018 Rolling for take off, Laughlin nevada with default weather's condition, Fan rpm gauge indicates 81% at max. But with "summer, heat" condition, gauge indicates 76% at max (you could read 74% at default pilot's position, not being aligned with gauge).
VFA15-Juliet Posted March 23, 2018 Author Posted March 23, 2018 Thanks! I found that in the -1 now. In hot and desert conditions section. Wow, well done ED!! Nice attention to detail.
