Hey everybody I an aircraft or two that (while on the ground) seem to have an idle that makes them creep forward. Keep in mind that these are NOT prop planes, they are jets. so their aircraft.cfg doesn't have the whole idle_rpm_mechanical_efficiency_scalar and the idle_rpm_friction_scalar that makes it so easy to fix in prop planes. Also I have 1 jet in particular that while decending with engines set to idle, it has the most horrible time slowing down. In fact, if I decend faster than 1500-1800 fpm it begins to actually PICK UP speed. I'm somewhat ok with the decent problem because thats what they make those bleedoff loops in the sky for right? Altitude and speed bleedoffs. However, upon approach i need to be able to get speed to bleed off quicker and during approach with idle thrust this plane (stoneair stingray) will usually either maintain speed, pick up speed, or if I'm lucky it will bleed off speed so slowly it takes about 10 seconds per knot of speed...which is which is not allowable for approach. Especially considdering you are supposed to bleed off that final bit of speed while you're on the glideslope.So my question is this...In jets, what can I edit in the .cfg (or add if necessary) to reduce the idle thrust while on ground and while cruising?

Under your aircraft cfg scroll down until you get to jet_engine and change thrust scaler to a lower number.Hope this helps.Kimmer

Well see thats just it. This particular plane doesn't have that entry in its .cfg. And considering the nature of this aircraft, the thrust scalar shouldn't be tampered with. it needs all the thrust it can get considering it goes up to around FL700-800 and up to Mach 4.7 (give or take about .05 mach). however I did find out 2 things that definitely help for both approach and taxi problems somewhat. Under the [generalenginedata] section, there was an entry called min_throttle_limit=0.00000. I changed it to -0.3000 and it more or less stopped creeping at full fuel...probably gonna go for about -.5 or so. I also changed the drag scalar for the individual flaps to a slightly higher setting...which allowed for a wonderfully controllable speed once the first flap setting was initiated for approach. After several pattern practice full stop landings I was satisfied with the new flap drag scalar numbers. Now the only thing to do is to test the decent problem and find a solution if the engine line I edited didn't work.Also if anyone wants to play around with this beast of an aircraft the d/l link ishttp://www.simviation.com/fs_concept5.htmYou'll find it about 3/4 way down the page. Its made by Mike Stone, and don't let the size fool you, its a nice aircraft. Even so, I made a few tweeks to the .cfg (obviously) such as making the rudder a little bit more responsive (for crosswind landings), slight thrust modifications, a ground steering tweek and an adjustment to the fuel flow to allow for longer flights using less fuel. If you would like a copy of the .cfg let me know and I'll post what i editedmy mistake it does have that entry, I just won't edit it.

Wrong, open the airfile with Aired, and goto section 1506, and lower the scalar for the wanted N1 setting..

Jg,I am wondering if you use the 'Auto Controls' panel or a different panel? It's been about a year since I tweaked and flew the 'Stingray' (in FSX). Made a video (no big thing) at YouTube (Link: http://www.youtube.com/watch?v=LVBxAHAE6ZA ).I do believe I added a spoiler to make it slow down as it IS 'souped up'. Can't remember if Mike gave this model a spoiler or if I 'forced' one on it. Can you edit the Air file? By the way, the min throttle limit is for reverse thrust and not REALLY for idle rpm. But it don't hurt anything.You want to work on dynamics, using email? Let me know in a PM so you don't make public your email addy here. I have the Stingray backed up in external HDrive and can pull it up and share files with you. Or paste section(s) you need here. You mostly need to add spoiler.CBNapamule

Well I must say that was an interesting video to say the least. Lol i took my edited version out for flight trials one day and managed to hit ceiling and about mach 5.08 on the way down...but that was one hell of a ride if i do say so.I do still use the stock auto control panel with a 737's radio stack added for VATSIM use because the default auto panel that mike put in doesn't have a transponder on it :(Mike did actually put a spoiler on it but that thing is a death wish waiting to happen if you use it on approach. I only use it for landing and for emergency speed/altitude decreasing.Lol changing that minimum throttle really doesn't hurt considering there is no reverse thrust.As a side note I would like to add that I can not and will not edit .air files unless ABSOLUTELY NECESSARY.oh and Napamule what i meant about posting stuff was putting individual .cfg lines into this thread if needed...
