777 Prepar3d v4 ILS Parked and blown Brakes on Landing

Recommended Posts

Hi there

 

I have just completed first 777 flight upon landing to Malaga i noted that ILS was Parked despite i had a ROute programmed in FMC... no one knows why this can happen ?

2nd  I landed with manual landing with Autobrakes set to " 4 " .. everything seemed right during initial touchdown but when i reached 80 knots pressed brakes manually to disarm autobrake .

Despite this,  autobrakes didn't disarm and stopped aircraft mid runway with "Parking Brakes Set " Sign on !!

I couldn't disarm parking brakes with "CTRL + . " i had to enter FMC Maintenance menu and change the brakes to move the 777 to the gate seams that i burned my carbon disks.. but it was the first flight after 777 installation

 

What happened ? my mistake ? Autobrakes 4 is too much ??

Why ILS Parked ??

 

 

Thank you very much for support

Hi,

1) You say you had a route in the FMC but did you select an ILS approach? ILS autotune sets the frequency and course for the ILS you have selected in the DEP ARR page of the CDU.

2) Autobrake 4 is quite much and not often used in normal ops. Use 3 for a runway 2200-2500m length and 2 for longer rwys.

You could even use 1 for very long rwys.

The temperature of the brake and the resulting possibility of getting the tyres blown depend on the autobrake setting, the OAT, the landing speed the landing weight mainly and the use of the reversers.

If you set autobrakes to 4 close to the max ldg weight on a hot day without using the reversers, you increase drastically the risk of getting the fuse plugs to release due to the brake temperatures hence having tyres blown.

One thing to keep in mind is that the setting of the autobrakes sets a deceleration rate. The autobrake will modulate the brake pressure to maintain the same deceleration rate whether you use the reversers or not. The more reversers you use, the less brake pressure will be applied and the less the temperature of the brakes.

Your first trip should be Tutorial #1.  Please review the Introduction document to at least see what information is available there.

As Romain mentioned, full names here please.

Thankyou all for replay

There should be some bug i think .. i have solved ILS problem, Landed again with Autobrake 4 without problems ..... but ... even after exiting the runway after a 3/4 minutes taxi tyre, brake disks .. all blown !!

before that i verified temperatures of gear with LCD screen , they were all at 2 !

as soon i pressed the brake  " . " command to get lower taxi speed ... bang... the 777 settles down with again the red message lower left conrner saying " Parking Brake set" press " . " to release

 

Have you already notice about this malfunction ?

In your setup, perhaps.

If this were a bug in our code, one might imagine that you'd see an entire forum full of posts where people are noting that they cannot taxi after landing, no?

Calibrate your hardware, and be sure to set a null zone to eliminate any dragging of the brakes.

I'm actually getting the same problem. I land on LAND 3 ILS, Autobrake 2, full reversers to 60 kts, i tap my brakes to disarm autobrake, and the Parking brake locks up and my mains pop. i replace the mains and a few seconds later they pop again. i cant release the brakes even doing a cool or replace. i cant taxi at all after i land the t7. it happened at taxi2gate vhhh, and fsdt kclt,

i didn't post after the first flight because i thought it was something i did differently from my flights on p3dv3 vs v4. after the second flight I am pretty sure its not me making a mistake. I will admit it could be FSUIPC5 somehow making the brakes stick on, but i cant see them staying on even after using default release methods and FSUIPC assigned keys. 

My next trouble shooting step is to not use Autobrake at all to see if that clears up the issue. then put it back in to see if it returns. I will post the results as I have them.

Make sure to go back in and set your brakes up in FSUIPC5. It doesn't automatically pull your FSUIPC4 settings.

Set the sim to send a reversed axis indication. Set FSUIPC to have a null zone at the bottom to filter out any application of the brakes. Without that, your brakes are dragging, and/or set full force, and, well...eventually hot brakes are going to fail things.

..I don't have FSUIPC at all

How can i solve the problem ?? 

Should i install it absolutely ?

I´ve the same issue after landing and start to taxi in the last 3 flights on different airports. Brakes are hot to 10,0 from one second to the other. In the fsx i´ve had 300 starts and landings with the 777 and no problem like this. 

I need help.

Correct. This is a new simulator, and I'm willing to bet that you did not properly set your hardware up in the new sim.

Yes I did.

What irritates me most, is that the temperatur increase without any handling of the brakes and with defined and previousely calibrated zero value.

So I´ll use the FMC ground setting and wait for further development.

This is incorrect.

If you're getting heat on the brakes, it's because the brakes are being applied somehow. That somehow would be your hardware.

Unplug it and use the F1/2/3/4 keys to control thrust. I'm willing to bet that your issue mysteriously vanishes.

Hello everyone!

I'm finding somewhat the same issues described here and in other topics: slightly more friction when taxiing and what particularly find annoying, after a long haul flight, when landing having the brakes overheated and tyres deflated as they accumulate temperature much faster than they used to do. Also, like some other members have pointed out, I'm finding too that i'm unable to disengage the autobrake by pressing the dot key after rollout when the aircraft decelerates below 70 or 60 knots, just like I used to do many many times before. By the way, I mostly use autobrake 1 or 2, and seldom 3 (I think I've only used level 4 a very few number of times when testing the 777's landing performance after release of the first version), therefore I wouldn't expect that under these conditions the aircraft experiences such strong deceleration and subsequently the rising brake temperature, with the ending result of a general tyre deflation.

From my own experience, I can tell I don't have P3D v4 yet, so I'm still on v3.4. I haven't changed any of my hardware (Saitek X-55) and I haven't modified my FSUIPC settings at all. In fact, my only change in the sim has been updating the 777 to the latest release, which is compatible with v4, although I still use it on v3.4. That said, to me it appears that all signs lead me to think that these issues are as a result of the recent PMDG's update to the 777. Obviously I'm not an expert in this matter, and don't know how the friction works in V4 in contrast to V3. However, I believe that there are a number of users which are experiencing this problem besides me. Additionally, it seems that this is happening either in V3 and V4 without distinction. As such, I tend to think that this weird breaking action and friction is a result of the update, and not the users' various configurations, specially when this has been reported by a significant number of users.

I've not opened a support ticket, as I think that topics like this one, will attract PMDG's team attention into this matter, and will revert the situation to the previous 777's behaviour as it worked very well before.

Thanks very  in advance much for reading and for your interest.

Yes I agree !!

this is especially good reading for Mr. scandinavian13 member that repetely say thats "our" bug and not PMDG's...

I was the one who opened this post and still trying to understand why my 777 now cannot land in normal procedure without blowing wheels and brakes,,

i boght 777 since first release and never had that problem.

 

Last night i re-installed X52 drivers and re-calibrated my hardwere with new Dead Zones.. now i'm going to re test a flight and see what happens

Hi,

I think you should submit a ticket to the support along with all people that have that issue. It will much more efficient than a thread in this topic even if some guys from PMDG may read the threads on the forum.

Submitting a ticket will get the issue tracked in the support system.

Did three flights this weekend. Today was the first time I used autobrakes 2. The results:

Friday: landing at MPTO, Vref 137, idle reverse thrust and manual braking - no issues, 

Saturday: landing at EHAM, Vref 137, idle reverse thrust and autobrakes 1 - no issues (brake temp value was 1.1 after landing).

Sunday: landing at HTKJ, Vref 137, idle reverse thrust and autobrakes 2 - brake temps through the roof and tires deflated

The same is happening to me upon touchdown, autobrakes 2, Vref 140, idle reverse thrust at Denver.

I have the 777x since 2013 with FSX, 2015 with P3D, and this started happening with P3DV4, never happened before. This last landing at KDEN I actually disconnected the autobrake earlier than in other instances of V4 in the landing roll, and managed to keep my tires OK although the brake temp was already high and joyfully rising.

Checked my controllers, and there are no conflicts, only one of them actually have braking input (or any control whatsoever). FSUIPC5 is the free version.

Yeah guys, same problem here. I own the 777 in P3D V3 and never had this problem. It's happened four time to me in V4. FSUIPC is setup the same way in V3 as it is in V4.

Turns out, I was wrong. I didn't see the issue on my setup for some reason (perhaps a beta version where we'd already corrected it). My apologies.

There's an update to correct this:
