[Philipp] PFD Distance/Time Bug + Thrust Limit + A few questions

[Nova]

Hi,

it's me, again...  : (to bad the rolleyes smily doesn't work  :-\ )

There are a few things i am not sure about if it's me, doing something wrong or if it's a bug.

1) In the pilot book, you have included a reduced t/o-thrust table. Situation: I am standing at EDDM. QNH 1021, 8°, 1487 above see level.

On page 17 it would mean that the reduced thrust would be then the value combined of 2000ft (must be rounded up until 4k) and 10° (always needs to be rounded up). The table says then: 90.2 N1.

But the PERF page says it's only 85.0 N1. And i guess this should be normal takeoff thrust. So how can the normal calculated thrust be lower, than the reduced thrust?

(While i was testing, the limit wasn't working at all. first time. some more investigation needs to be done by me here. however, just to notice this: 82 TGT resulted in 87.9 overshooting the limit on the display, while 90.5 resulted in 94.5 N1)

2) The limits for TO/CLB/CRZ are always 85.0 as long as the temperature is below 15°. With 15° is says 90.1. With 16° back to 85.0 until 19°. 90.1 @ 20°. 21-24 85.0 and 25° = 90.1 again. Not tested further, but i'm sure it's always the same from there on.

3) Distance on the PFD is calculated wrong. I did the following route: EDDM EGG5S DM449 DM439 GUDEG MNW EDDM (ILS26R). If i add all distances of the LEGS page, i get a total length of 93NM. The distances are as followed (from holdingpoint 26L B14):

The distance from the PFD says 119NM. If i add the length of the missed approach procedure (to MIQ NDB back to EDDM) i get a total distance of 123NM. As you can see in the screenshot, even the second wayoint (MIN VOR) is already wrong. 35NM PFD vs 13NM LEGS page.

4) If you are on a longer flight and you get a DCT from a controller, you have to delete the waypoints. This can use some time, if you have to delete multiple fixes. Is there a chance, that you will include the DCT function in the next patch?

5) And this leads me to another thing i noticed. When you delete multiple waypoints to get the direct done, the PFD doesn't calculate the new distance. Even if you save 60NM thanks to a shortcut, is stays the same NM and time to reach. The difference gets smaller the closer you come to the airport. If you then change the arrival, it's calculated right again. Just try it. Happens to me all the time.

6) Last time i forgot to set the nav input to fms. This caused the plane to use only "roll" instead of "fms" after takeoff. After setting it to FMS the plane wasn't turning. I had to set the HDG so i would fly towards a waypoint on the route. While HDG was active, NAV was armed (clicked and lights active). When i was near the waypoint FMS started to follow the route again.

Is it possible to get the plane on route immediately without the need to use the HDG? Did i miss something in the manuals or is this how it works? Since the DCT buttons has no function, using it was not an option (like in the x738 for example).

7) The integral lights are always on, and this is an restriction from X-Plane, as Japo once wrote, except the fact, that dome and overhead lights are off after cold&dark after switching on the battery. However, the clock displays are attached to the integral lights switch. So i cannot turn them down (because not needed) without loosing the watch. Working as intended, or maybe a bug? I would like to be able to adjust the watch light either seperate or have it on max all the time.

8 ) When you have the FMS or anything else as a popup, you can still click buttons that are hidden behind. This is sometimes a bit annoying since it can happen, that you reset your altimeter to default, or click other knobs like nav source etc. Is it possible to make it a "solid" surface, so you cannot access the things below?

Thanks for any answers

9) Just noticed that rudder/aileron/elevator trim is not animated on the model. Nothing is visible with even full trims.  :-\  :'(

[Cameron]

Philipp will be here to answer systems questions soon.

I'll have Javier look into your claim with the animations.

[Japo32]

8) Just noticed that rudder/aileron/elevator trim is not animated on the model. Nothing is visible with even full trims.  :-\  :'(

This is another case of "I imagine the plane I want the CRJ to be" and crash with "the real plane is not the way I dreamed to be"

You won't see any moving part of trims because the plane hasn't. What it do is make a new "zero" position for the same aileron, rudder or elevator.

Here is what FCom says about Horizontal Stabilizer Trim for example:

The horizontal stabilizer trim system provides pitch trim by varying the angle of incidence of

the horizontal stabilizer. The horizontal stabilizer is positioned by a screw jack driven by two

electric motors controlled by the horizontal stabilizer trim control unit (HSTCU) through a

motor control unit (MCU). Each motor has a magnetic brake to prevent trim runaway. Trim

range is from +2_ (leading edge up) to --13_ (leading edge down).

So as you can see in images attached there is no moving trim elements in this plane.. and what it does the plane for trimming is just reposition the zero angle to a new angle position.

Another clear case of "I thought the CRJ is an 737" hahaha... anyway...... patience lord!!! give me patience!!!

[Japo32]

About your first post... .. well I would recomend next time concentrate in one question please.. it is too long to me to consider all situations...

Ok.. from what I know right now.. the thrust limit is only working correctly with tables in pilot handbook. the 85.0% stuff is something that we leave there (and we should not) that is confusing you. It is an advance for future updates (as well as others you don't see. There are more pages of the fms already done, but needs to be completed. Secondary functions not needed for a perfect flight of the plane (before you ask why we didn't included or worked on them).

7. Lighting in this plane is tricky.. and because is triky as well as the rain.. it has it's little """""problems"""" I would say (and told thousand of times) this plane isn't perfect and becuase I don't have a perfect solution for making lighting in X-Plane 9 (xp10 will increase this!!) then I have to make some tricks that as magicians.. you can discover. So let see magic and don't wonder about tricks unless you want to learn make planes. It will be better for you.

6. Again "I want a 737 inside the CRJ".. Ok. HDG is necesary until the plane CATCHES the route. The computer doesn't know where is the route until it is near it. And of course you have to enter the route with a low angle between the way you enter and the route direction. IF not you will overpass the route.

7b) solid on popups.... well that is something Philipp has to reply because I don't know... it is programming stuff.

4) I would like to introduce a direct faster way.. (we still have to study the fms if that is real to do). But right now you can introduce a direct very fast. Just input the new waypoint (even if it is inside the legs page.... or copy it to scratchpad) and then insert before next waypoint... the plane will start its turn to that point... BUT you have to delete others manually... if not... the plane will return to previous. But this time you have more time to do that, I didn't find any problem in my flights even in STARs.. where all the points are so close. See the Tutorial about this one.

2) as said.. that limit is still to be done on future updates...

About other points I think Philipp can reply then better than me.

Thanks

6. Again "I want a 737 inside the CRJ"..

I don't want a 737 inside. I just haven't flown many other planes. I only know the x737

and standard X-Plane FMC and those work like i described. So those are the only ones i

can compare with, since i have no clue what a CRJ looks and feels like. Well, i don't even

know this about a 738/752/742.

For the missing animation: thought you might have forgotten about it, like tkyler did it

with the MU. ;D  If it's not animated/if there is nothing to animate then ok. Looks like the

difference is barely to see anyways. Not a big deal, just wanted to point it out.

I don't like making a thread per question/possible bug/user error. Thus i though using

numbers would make it easy enough to reply. Next time, i'll post 9 topics. ;D

PS: Just noticed, the "cool" smily in the first post should be an eight. And the one after a nine. (edited)

I noticed what may be a related bug: Yesterday I was flying a plan which had the first waypoint near the airport. I was late on my first turn and misses the first waypoint, but adjusted the heading bug to hit the second waypoint. However, I forgot to delete the first waypoint, so the FMC still considered the first waypoint to be the active one. As I moved away from the first waypoint, and towards the second, using HDG mode, the distance shown to the second waypoint increased, even though I was flying towards it.

Deleting the first waypoint sent everything back to what it should be.

This is accurate behavior.

About overshooting the thrust limiter: See known bugs, it is highly dependent on the type of hardware input you use as the throttle axis. For the 1.1 patch, I changed the design so it should work with whatever hardware throttle input you use.

About selecting the limit by temperature in the FMC: I have no idea, because I got the tables the way they are and didn't change a thing. If in doubt, I would trust the pilot handbook more than the FMC, and this is also what a real pilot would do.

About the distances: Please keep in mind the FMS shows intermediate distances, while the MFD shows the accumulated distances (from where the plane is now!). However, the accumulated distance recalculation after making a shortcut has a bug and fixed in 1.1

About making shortcuts: It is not true that you have to delete all intermediate waypoints by hand! Just select a waypoint on the route, insert it where you want it, and intermediate waypoints will be deleted. Just like the real thing, no need to do a DEL on every waypoint.

Thanks. Will try that this evening.

Ok, your tip works great, much faster. BUT, he will not fly a direct line from his current position to the new one.

As long as the DCT is somewhat near the current direction, everything will be fine.

When i was on my way to MUN VOR i made EGG VOR my direct (i used the flightplan in the first post, once more).

Copied via LK and inserted it right on MUN VOR. The result: a straight line from DM050 to EGG.

The plane immediately turned left to intercept the displayed line. Does the real one fly like this too?

If so, what's the purpose of being able to use directs, if the plane starts heading somewhere else instead direct

to the waypoint?

[Japo32]

when I set the point I want to go direct It always go direct to that point... In my case of course.

[Nova]

I made some screens.

A few seconds after takeoff (EDDM 26L). FMS as nav source, ap enganged while on way to DM049.

A/P turns direct DM050.

After a while i copy EGG and past it onto MUN.

With this new route as a result.

The plane then makes immediately a left turn, to cut the route plotted on the display.

And will then turn right, to intercept the shown route.

This is 100% reproducible.

[Nova]

And to make sure its not a problem with this specific route, i made another test.

EDDL to EDDN, 23L KUMIK departure. After DL241 on my way to ELBAL (20NM to go)

i made TESGA my direct. Same thing happened as before. Plane made an right turn

to intercept the new plotted route, instead to just go straight for it.

[Japo32]

but are you pressing the direct very close to the direct point? I mean...

A - B - C - D - E - F - G

you have passed C going to D ... just want to make a direct to F.. ok..

copy F before D point but FAR FROM D.. .not arriving.. better then copy before E.

Maybe your problem is that you are copying it so soon before one point.. Maybe I am missing something.

Lets wait Philipp.
