EPR and Fuel Flow Lag

Recommended Posts

Hey all,I am having a strange problem, the EPR and Fuel flow are lagging the EPR sometimes increases too slow i.e. I will have my throttles at say 2.15EPR and the epr gauge finally reaches 2.15 at the time I rotate. Also sometimes the Fuel flow gauge gets stuck at around 1.2. I dont know whats causing it, here is a screen shot in flight.fsscr016.jpgSometimes its both gauges and sometimes its just one and sometimes it dosnt do it at all. If its because I havnt read something I apologise! I am upto date with the updates.Matt

In the pic it looks like the left throttle is pulled back to idle. Might want to check your throttle axis calibration, or FSUIPC throttle mapping assignments if you have a single throttle lever mapped to multiple engines via FSUIPC. Also, FS has some key assignments for throttle select...could it be you're accidentally triggering them?Not sure what you mean about having "throttles at 2.15 EPR"...how do you know what EPR they're set to? If you mean the EPR bugs, they are only reference markers for the pilot. EPR does increase some at a given throttle setting as the acft accelerates on takeoff due to way FS models throttle versus "corrected" engine fan speeds, which change with mach no.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

I did calibrate the Joystick, that diddnt seem to help, it only sometimes seems to do it thats the strange thing. If you look at the gauges only the EPR and Fuel Flow seem to differ, if one throttle wernt aligned wouldnt the N1, N2 and EGT be out of whack aswell.I know the how the PCDS and EPR bugs work, but I push the throttles up on my joystick to where 2.15 epr SHOULD be (estimated) and the epr gauge only reaches that at rotate the N1 N2 and EGT all shoot up normally.Its kinda hard to explain but I hope you can understand.

What EPR does the engine show prior to rotate?What version of FSUIPC are you using?How are you starting the engines? Hopefully not with CTRL-E.Have you merged the plane with another model or otherwise modified the aircraft.cfg to change the contact points section? If the panel does not detect that it is on the ground properly, it could cause related problems.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

Another way to put it is that the EPR Gauges are Very sluggish. In this picture it shows me in flight the FF gauges diddnt move after I started the Engine.fsscr019.jpgSometimes its just one and sometimes its both. This is driving me mad!I start the engines with the engine start knobs with the APU/APU Gens/APU Bleed air on.Btw I dont think I have said a big thanks for the panel its superb!

OK...need more information as per my previous post.Again, I need to know what version of FSUIPC, and what model and config you are using. Is this a merge of the TinMouse II panel with some other model and/or FDE? Are you using one of the two aircraft.cfg files included in the TinMouse package? Our 737-200adv.air file, or something different?RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

I am using FSUPIC 3.5.3.0, I am flying the Air Atlanta Icelandic 727-300, I downloaded these 4 files Base package (V1.2): http://library.avsim.net/download.php?DLID=92047Update patch (V1.21): http://library.avsim.net/download.php?DLID=92339FDE Update (V1.22): http://library.avsim.net/download.php?DLID=92823Model Pack: http://library.avsim.net/download.php?DLID=90552Installed them, I am using the Default aircraft.cfg in the Panel.B732ADV folder, I also have the CIVA Ins Installed.

Note that in every version of the readme since V1.0 it specifies FSUIPC version 3.6 or greater is needed. You are running version 3.53. Recommend you update FSUIPC to the latest version and try again.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

I am using FSUIPC V3.71, and panel v1.22, same problem with me, the problem occur only when i shutdown the engine, and start the engine using manual start (using knob), to solve this problem i assign key through fsuipc key, using autostart engine 1 and engine 2. maybe this can help.RegardsRW168

OK, I'll take another look tonight. A post in another thread suggests it's only happening at OAT greater that 24 deg C. CheersBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

Not seeing anything obvious in the code, but there are a couple possibilities. Is this happening only on the ground? What's the OAT and TAT when it happens?RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

yes, you are right i had trie the panel when TAT 15, the epr and fuel gauge work correctly, when TAT 32, the epr and fuel flow gauge become stack, please some advice how to solve this problem???without using autostart through FSUIPC, thanks.RegardsRW168

For now all I can advise is fly with temps <= 15 deg C. Working on a fix...not sure when though.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

I flew today in 22 C with no problems, I havnt had any problems scince I installed the Reality XP 430 GPS. Also I still have the older version of FSUIPC.Matt

Just confirmed the bug. See my post in:http://forums.avsim.net/dcboard.php?az=sho...d=661&mode=fullAs long as you start engines with temps between around 8-22 deg C you should be OK...closer to 15 is better. Basically engine is staying stuck in final phase of custom start sequence.Check and see if the start switch solenoid ever disengaged...bet the switch in still in GND.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

Do you mean the starter switch thingey? (I am so technical! lol)The starter cuts out after I engage the Fuel to that particular engine I hear a click and it clicks off.BTW if there a 732 checklist out there?

Actually, the starter switch cutout is not related to the problem...it should cut out normally at ~38% N2 come to think of it.There are a number of 732 checklists out there...a few posted in the early days of this forum in fact. Try using the search feature here.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

The TinMouse II V1.23 update, which contains a corrected multigauge file, has been released to the library to correct this problem. Filename is tinmouse2_b732_v1_23A.zipEdit: I accidentally uploaded tinmouse2_b732_v1_23.zip without the updates to the #2 N1 and N2 gauges...the hazards of having my stuff spread across three PCs while I build a new FS machine. Hopefully I got it deleted before it gets to the Avsim library...if not, make sure you use the "1.23A" version.There will be a link to the file in the FAQ.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

Thanks Bob for your update, the panel work perfectly, but when touch down the plane crash, i set spoiler arm and autobrake set to max, version 1.22 did not have this problem, maybe something missing in autobrake gauge, please advice to solve this problem, thanksRegardsRW168

I dont seem to be having any problem with the new gauge, works for me.Thanks Bob!

It...crashes? You mean it explodes into a fiery show of bad MS special effects?Autobrake gauge is the same as in V1.21. Make sure you haven't inadvertently changed a button or key assignment or something else to set the parking brake in the air, or if you have an axis assigned to the brakes (i.e. toe pedals) that they are in fact released (0 value) at touchdown. Can't imagine any of the minor changes made to the engine start sequence has anything to do with this.CheersBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile

I mean the aircraft explodes after touch down, i use default fs parking brake key, i never change it, in my case, after the aircraft touch down before front wheel touch the ground, the aircraft directly brake, i set autobrake to max, and arm the spoiler, then the aircraft explode with nose touch the ground. i have try this many time and the result is same. ThanksRegardsRW168

My best advice is to turn crash detection off in FS...it does a ridiculously bad job, particularly with hard landings. Also, some scenery can cause crash detection to trigger, like when you're taxiing and start to get a bounce due to terrain layering issues. With crash detection turned off it's just an FS annoyance when it happens...with it turned on, when that happens your flight is over.That said, you can go in and increase the max descent rate threshold for the nose gear...in the aircraft.cfg file in the "contact_points" section edit the 5th parameter in the point.0 line to something larger than the default 900.0--perhaps 1500.0 to match the main gear.Also, I'm assuming you're not using somebody else's merge config that may have other related problems related to the contact points.RegardsBob ScottATP IMEL Gulfstream II-III-IV-V L-300Santiago de Chile
