X-Plane 10.10rc3 bugs

[TylerE]

1. Arrow for elev trim is not centered correctly...it's range is from around the 0 mark (with full down trim) to about a foot ABOVE the gauge, with full up trim.

2. Engines seem to start to easy. I had no problem starting both at the same time, even at -20F temps, on the first try.

3. Many of the guages to not read quite right, for instance:

Note rpms are at 2066 but gauge reads about 2120 - and on the vertical speed, the guage reads +100 when the actual vs is -37fpm

[TylerE]

Another sort of bug - I don't believe that the DC-3 was typically fitted with a 6k FPM VSI - the photos I've found most frequently show a 2k range - this would make it a bit easier to manage climbout, since the climb rates in this aircraft are so low.

We know about Number 1 and it has been fixed. It was a flight model adjustment that was changed between versions 9 and 10 of Planemaker.

Number 2 is more an X Plane thing. It uses X Planes default engine start up logic. I guess we COULD code it to start in a way that would reflect more realism of the real DC-3, but it needs to be looked into.

When you say "Many of the gauges don't read correctly", are you saying that it is just the engine RPM and VS or are there more. I'll have a look at the engine RPM and VS, but if there are more, could you please post them so I can have a look. I've had a look at the original 3D mesh and its animations, and all is animated accurately. I won't point the finger at X Plane yet until I do further checks.

During researching this aircraft, I literally came across close to 100 different variants with a vast difference in panel layouts between many of them. I settled on one and that one had a VS indicator that went up to 6000 fpm. This could have been a retro fitted VS gauge taken from another aircraft. I honestly wouldn't know. All I could do is make this add on according to the variant I chose. I'll have a look at some other photos and see what I can find. If the VSI does show up to a 2000 fpm maximum climb rate, I'll talk to Theo about re-texturing it and I'll make the necessary changes to the movement of the needle.

Those responses are totally fair and reasonable.

As to the gauges, I'm only 100% sure on those two, will check some some more next time I fly.

Found another bug which is probably the biggest of any of them, as it renders the aircraft unflyable in some conditions...

Anti-iceing only works on the LEFT side of the plane.

Steps to duplicate:

Set weather to 12 degrees F, extreme precipitation.

Turn all anti-icing on with engines running.

Turn on icing status in data output

Watch as left prop and left wing stay at 0.000 and right wing and right prop quickly build up ice.

Is there any fix for this icing issue? I couldn't figure out the problem as I crashed 3 times in flight and figured out the same issue. Icing only works on the left. Will this be fixed?

[Goran_M]

The "official" update is still being worked on and is not ready yet. But I will try to reproduce the problem and, if it isn't too complex, I will outline a series of steps for you to take to make adjustments in the flight model.

Expect a post soon.

Anything yet? I haven't been able to use this aircraft yet as I fly up in Yellowknife and there has been constant snow for the past 2 weeks. ha ha.. Really would like to put this bird to work. :-)

I've just had a very thorough look through the flight model and also some other aircraft. It appears to be an X Plane bug.

I loaded up the default King Air, set temps to 12°F with heavy precipitation and turned on the Engine Anti Ice (INLET in the top right corner in the screenshot below). Left Engine works fine. Right Engine, icing continues to build up.

Could I ask you to try another payware aircraft (Equipped with Anti Ice) and run the same icing tests.

I tried it on the King Air because it;s an X Plane default aircraft, and if anything should work, it'll be a default aircraft.

EDIT: Bug report has been sent to Laminar.

I'll post back with any replies I get.

Thanks for your patience.

hmm.. I tried the XP 1900D and no issues. Both sides work. I tried another DC-3 I bought and it works no problem.

On the Jsim Q400.. same icing issue with left working and right not.

Carenado 208 same icing issue. This seems to affect aircraft that were designed before v10. Would I be correct in assuming this? :-)

I just spoke to Tom Kyler, who made the default King Air, and he spoke to Ben Supniik about this icing issue, and they both confirmed it IS an X Plane bug and it has now gone higher up the chain to be addressed.

X-plane 9 or 10 ?

Anyway, I found the same issue with the S92 (helicopter), XP9. Thank you for the information

[Goran_M]

This bug was specifically for XP10.
