Guys enough with the sniping please.

 

==========

 

Tim,

 

The 777-200LR and 777F are both incredibly overpowered airplanes that have no trouble climbing even at MTOW. I've seen over 3000 fpm before above FL300 with it. We certainly did not model this wrongly and make it underpowered nor was anything like what you're describing seen in testing.

 

There's a few things that could be at play here:

 

1. Weather. As others have mentioned there are well known issues where FSX will suddenly go haywire and result in extremely high TAT/SAT up at altitude. My best guess is that this is what you're seeing. Look at the TAT reading on the EICAS - up at high altitudes it should be well below 0 C, but I'll bet yours is 30 C+.

 

2. FSUIPC - there's issues that can happen where FSUIPC stops the internal FSX "throttle" from commanding the engines correctly. The fix is to delete the FSX/Modules/FSUIPC4.ini file and let it rebuild.

 

I will be very surprised if one of those two issues isn't the cause of what you're seeing.

On a computer Adam, On a computer!!!

 

 

Tim, what are your Opus settings. Check to make sure all weather settings are default. Tick any Auto options as well. Post important, Opus released a new beta today that should help, and has PMDG weather uplink available as well.

 

Cheers

 

Thanks Julian, I will look into it.

Tim Carter

 

Thanks Ryan, just saw your latest post, while frustrated I am not necessarily saying its PMDG fault.  I know am aware of the capabilities to the 777 hence my initial post.

I am in no way saying this is the experience everyone is having but I think you would admit there have been a few issues crop up that made it through beta testing.

I will have a good look at Opus and apparently there is an update out there so will get onto that.  I did also have a few teething issues with throttles through FSUIPC and deleted the calibration that appeared to fix it.

Perhaps I should delete the ini and see how we go.

Regards

Tim

What's with the bickering? No wonder the moderators and developers are getting frustrated. Whatever happened to acting civil...

 

As mentioned, weather (temperature in particular) could be a strong factor here. Try the default Clear Skies weather setting without any wx-engines running, and monitor your temps when using the wx-engine. Also, how's your nose pitch when retracting/accelerating? Veirfy engine thrust settings, and check for any ghost key mappings that could cause some havock (maybe your throttle overrides the A/T? If so, that's an easy fix via the PMDG settings). It wouldn't hurt if you gave a rough step-by-step of your actiosn during climb-out either.

Tim,

 

Another vote for checking out FSUIPC. For whatever reason a lot of folks are having to delete and regenerate their FSUIPC.ini file in order to get throttle and/or flight control authority. I had no rudder or ailerons myself. That would have been an ugly takeoff--had I forgotten to perform my flight control check.

V1, Rotate... erm... Rotate? ROTATE??!!! OMG!!

LOL then a quick call to the NTSB Go Team

Hi Magnus

Sorry about the bickering, Adam just made me see red. 

I thought I had gone thought the steps relating to the issue pretty well but perhaps not.  As I said conditions were raining hence a full power take off (no reductions when wet - sop) to Clb 1 power governed at 1500' and acceleration altitude of 3000'.  Had LNAV and VNAV armed prior to take off and hand flew the aircraft to about 1300'.  Engaged autopilot and watched the power roll back.  Nose dropped to maintain speed as expected.

The 777 went up like a rocket and as I accelerated through the flap 5 retraction speed dialled in flaps 1.  Passing Flaps 1 speed went to flaps up.

OAT was indicating ISA -3 (ie. 12C at the time).

This is where things went south.  Power was aprox 90% N1 and fpa angle was about 12 degrees.  Speed bled off with nose pitching up and approached the stall. 

Manually flew the aircraft after disengaging the AP.  Recycled the FD, AT and AP and as I said during the climb it wallowed around and flew 30-40kt below commanded speed (320Kt) while the AP was engaged in LNAV and VNAV with AT also online.

Hope this explains what happened better.

Regards Tim

 

 

Meanwhile, please try a flight without OPUS...I've had issues with incorrect outside air temps (way too high), strange wind shifts, and annoying cloud popping (I know...irrelevant) with this program, which I did buy and have pounded the support forum in order to configure it properly. For tubeliners at altitude, I'm sticking with ActiveSky all the time.



I mention this because when I've observed Opus injecting ridiculously high outside temps, of course the 777's engines will wallow. Hope this helps and that you're able to track down the issue. Good luck!

Have you tried the betas opus releases every few days?

with all due respects Tim is the most qualified Airman on this forum while we all sit behind out desks and pretend to be aviators we should take Tim's comments seriously !

 

Not claiming to be the most qualified anything here Clayton.  I am trying to relate an issue that occurred during a flight that I don't believe was operator error that is all Clayton.  I have a reasonable amount of RW experience and have detailed as best as I can the circumstances under which it occurred.

If the PMDG groupies want to stick their heads in the sand and believe that PMDG could not have possibly released a product with the odd kink in it, then that's their problem.  I suggest they read the forums here about a number of issues going on.  While some may be the consequence of not reading the manuals etc this is not one of them.

 Not sure if that was trying to be sarcastic but certainly sounded a bit like it.

Looks like some kind of computery conflict of softwares or hardware. Something that isn't a feature of real world flying so much, afterall there's no FSUICP or Simconnect settings in the real 777.

 

Real pilots tend to focus on the 'real world troubleshooting' angle a bit, when the problems may be pc/microsoft windows/FSX.cfg tweaking based problems.

 We'v already seen a few oddities with configurations that conflict with the 777 and do wierd things to it, including fsuicp settings, weather injection of various programs etc. I'm sure this is the same kind of thing, because my 777 has been running pretty much to the numbers without much intervention needed. Hopefully the resolution for this little problem can be found and fixed too.

hi Tim

 

I think it could be a throttle issue, are you using an external throttle by any chance? Maybe that needs to be configured or recalibrated.

 

 

Clayton

Am having a look at all possibilities Clayton including FSUIPC ini ,Opus weather updates etc. To answer your question, yes I have a Saitek yoke, throttle and rudder pedals.

Will give myself a break for a while and take a fresh look at the computer and its settings as well.

In all honesty I don't know why when an issue gets reported people seem to think we make this stuff up.

I consider myself a reasonably accomplished rw pilot with good theoretical knowledge yet some pimply faced kid seems to think I am posting this stuff up for the good of my health.

At the end of the day, I have seen a bit of strange behaviour from the PMDG B777 - (none of it deal breaking or a death sentence) that did not occur at all with the B737 series and I think there may be some gremlins still in the system somewhere.

I hope PMDG take the information I am relating to them seriously while I try and investigate from my end, my computer and possible conflicts.  End of story

I don't think you're making this up at all, but you really should just TRY what we're telling you to try before assuming that there's something intrinsically wrong with the aircraft simulation. It has absolutely nothing to do with your abilities. It's simply because there could be any number of external issues at play here. Like I said, FSUIPC is a huge one in terms of the problem you're describing. Opus, too, sounds like a probable culprit (I don't have it, but it stands to reason that it could play games with such a complex flight model).

 

Point being, diss the jerks who keep trying to question your ability. But don't be too quick to jump to conclusions by questioning the quality of PMDG's work product. I have a "not insignificant" amount of RW experience myself, and I am extremely impressed by the fidelity of this simulation.

I have opus and it havent gave me this type of reaction. Will love to help you. Hope you find your solution soon! 

Also you might want to go here http://forum.avsim.net/forum/577-the-opusfsx-forum/ this is opus forum 

I normally stay away from threads full of thrashing and bashing between members. If a product is bad - tell everyone. If it is good - tell everyone. However, I am glad to see the constructive and informative comments and suggestions that have been submitted considering I have yet to buy the T7. When I do get it I will be well read (RFTM) and be on the look out for these potential issues.  

 

- Tim, I am curious to know how the aircraft performed during other phases of flight.

 

Good night to everyone.
