I have problems flying most complex procedures using the Airbus package/MCDU. It seems incapable of doing anything accurately in terms of lateral and vertical navigation. It's like flying with the default aircraft/autopilot, no, infact it's worse! I went back to the LDS 767 tonight and wow it's nice to fly with a reliable aircraft again!!

I also have the problem of my flight plan dissapearing on the ND everytime I want to go direct somewhere, VNAV just not working, GC glass crashing with setmessages and a list of about 100 major problems :( . Enrico and the team have known of these probs since last November and no offence to them because I know they try, but the problems they have fixed have caused countless other problems with relating systems/logic.

Hi,
I reported all above bugs and many others items to support already.
The total accuraty of the Boeing CDU route and navigation management presently seems to be very poor. I don't know what is happening these last month's but it looks as the problems are widely spread.
According Bob, Enrico seems to rewrite the CDU source.
Hope there will come some good news from support in the near futur, as it is very frustrating to use the CDU software presently.
I feel it as a big pitty, that no direct communication with Enrico seems to be possible anymore. I remember with great happiness the days there was practically a daily interaction between Enrico and its customers on the companies support forum. I know he is a very hard working guy, but at least an auto-reply, to know that support have received you mailrequest, would be appreciated.

If they are going to rewrite the CDU (i hope) it would better to inform customers about that!
Keep us up to date can make a big difference, public relations is very important!

Less travel to fix the bugs would be nice too! I always see someone of PM is abroad :D
Why going abroad? I think to sell the software, but do you sell bugged or not correct working software?

I wish Enrico will pop-up soon to communicate with us and with a solution!

Best wishes!

The almost last lifeline seems to be cut. Old PM forum is out of service now.

Just hope that this is not a bad omen. As far as I recall the aerosoft MCP 747 started to pull back in similar way.

Good luck to all of us

May I ask - is this navigation problem due to the CDU or the FS autopilot?

I don't undestand..People like Trevor and Bill are hailing the fantastic performance, and you all find it terrible... how can experiences be so different? Did PM ever work properly in navigation department, or is this all a new thing? If so, can't it be easily fixed?

Having no support seems weird -- wouldn't this guy be able to check his email on the road? How come any other member of the PM team can't help?

[737aqua]

So, basically, did the LNAV ever work properly in the past? Is this software not doing what it said it does? Shouldn't there be some accountability from managment if the product is not functioning. In any other industry, if the product doesn't work, some kind of compensation is usually given.

I want to know: If i buy PM software, am i just buying into a project that may or may not ever work to specifications? Is it just one big experiment, because if it is, its one heck of an expensive gamble which isn't fair on users. The product should do what it says it does. It says it offers accurate CDU/LNAV, and then it doesn't..so what gives, I don't understand??

All this talk makes me soo nervous, especially since there is no one around to give support. I think it was a terrible move to close the old forum.

Again I ask -- why can't PM answer support questions even while travelling, don't they have e-mail on the road?

[Bob Reed]

Again I will SAY!!!!!!! PM worked fine untill they started working on the CDU. Yes Lnav and VNav work. That is MCP not CDU. If you send questions and bug reports to support@projectmagenta.com they will answer. The PM crew does not hang out in this forum. I am using an older version of the CDU and my PM suit works fine. You seem to have a lot of fear about PM. My suggestion to you is NOT to buy it.

[737aqua]

Ok, LNAV doesn't fly the approach properly and that is the CDU in combination with the MCP (check original post and others) - don't think i don't know what LNAV is and how it works, because I do. There should be a notice/bulletin by the staff if such a problem is going to be expected with changes to the CDU - it seems they don't give out enough information.

Also, there is no other choice in home cockpit software so I probably will have to buy it. There is no fear, i just expect it to work like they say - I don't expect to be scammed. Also, no-one has answered these people's requests for a long time - they have a right to be worried.

[Bob Reed]

LNav is not approach mode!! No one said you didn't know Lnav. I say you have no idea what you are talking about with PM because you do not own it nor have you tried the demos. Until then you have no idea what you are talking about as far as PM is concerned!

[dcutugno]

From PM support:

Hello,

thank you for this. I will try to reach Stefan to understand whether he is
using the right converter.

Ciao

Wich version of CDU do you have? can you put it in there so we can download, PM doesn't offer older CDU version 'cause they say are obsolete!

Excuse me, but you are not understanding what I'm trying to get across here. I was saying that user who posted this thing couldn't fly a dme arc STAR approach using LNAV/CDU together - i am not talking about APP mode. The CDU is involved in LNAV, that is what I was saying.

I know what LNAV is from other programs such as PMDG - don't try and put words into my mouth please. Just because I don't have PM doesn't mean I don't know how A/P/MCP works, I am very familiar with the sequence from other programs and I know how the systems should behave. It seems clearly that they are not working properly according to the people here. The aircraft should fly a path without deviation when in LNAV according to the STAR entered into the CDU.

Can you explain what "right converter" is referring to?
Thx
Aqua

[Bob Reed]

Now it is you who are putting words in someones mouth. Here is the DIRECT quote that I made "Until then you have no idea what you are talking about as far as PM is concerned!" IN REGARDS TO PM nothing more.....

[737aqua]

Em, PM is supposed to simulate the LNAV function that is found in aircraft systems - i know those sytems and according to people's posts here, PM isn't behaving like a LNAV system should at this time.

[NicD]

Bob - which version of CDU are you using, and does that work with the latest navdata?

Another issue I'm noticing with the MCP is that LVL CHG is very unreliable, if not downright hazardous. It commands strange climb/descent profiles (illogical) and huge speed increases on descent - when it should be commanding A/T at idle. I have to use V/S all the time now when not using VNAV.

[Bob Reed]

Hi Nic... I am about to go downstairs and I will let you know what versions of all the software I am running.

[Trevor Hale]

Nic,

Just for information Here are my Versions, and I don't seem to be having issues.

MCP Ver 410
GC Ver 436
PM SYS Ver 84
PM FMS Ver 372

Regards,

Trev

[Bob Reed]

My versions are:

MCP 413
FMC 385
PFD 437

I am runing the Beta of the new navdata. I hope this helps.

[NicD]

Thanks guys ... think I'll try and revert to some older versions for a while.

[michelmvd]

Hi Bob and Trev,

Thanks a lot for mentioning which versions you are using. It is clear now that we are not speaking about the same versions, as we are using the latest "stable" versions from the PM website (GC448, MCP418, CDU388 ) + latest navdata airac 0703 from Navigraph.

It looks very important for me for the futur, we mention the versions we are using, when we talk about the bugs, as otherwise we are comparing apples with pears.
It would maybe be very interesting if both of you guys try to use the latest builds also and see if you have the same good results on your systems, as you always said you have. Otherwise this gives a false and wrong impression.

To Aqua,
From the messages between PM users, you maybe noticed that there are some bugs in the software, but at the other hand, PM software in unique in its kind and at this moment unreplaceable for cockpitbuilders. The PM software suite with glasscockpit - display software, pm system logic, mcp and cdu - all fully programable according type and able to work in a full network environment is an absolute must for cockpitbuilding. I'm using the software already for more that 6 years now and I have seen it growning a lot. For the record I'm not associated with PM, but a long term user who has maybe a critical eye but is very objective.

It is certainly true, that addon's for MSFS use on single PC, as Level-d, PMDG737 /744 are working more in details according the operational manual and with a correcter or extended system logic, but they are useless for cockpitbuilders, simply because there is no interface information available.

It looks that the present problems in the CDU came up, mostly due to a change of navdata format/info. As the free DAFIF worldwide navdata information from the USAF is no longer available for whatever reason, the community had to switch to a commercial company Navigraph to obtain up to date navdata airac information, which is a absolute must for people who likes to fly as real as possible with the online ATC services.

I'm sure Enrico will find a solution, as according Bob he is re-writing the CDU source. It would be great if he could communicate the progress here.

Hi Michel. I can not do this today but I will see if I can fit it in by the weekend and let you know what I find. What I would like to do is upgrade 1 peice of software at a time and see what that does. I bet all is fine untill I add the new CDU... We will see...

[michelmvd]

Hi bob, Thank a lot for your help. Please don't forget to take good backups ;), I wouldn't like to see you mess up your project ;).

Hi all..

I also have troubles with sid/star with the CDU buildt 388..

EDIT: **corrected the CDU version**
Have downgraded it to version 385F and it seams okey now..

Also downgraded my MCP down to buildt 414. With the newer builds the MCP its releasing the breakes when I spooling up the engines before takeoff.. (I have reported it to pm-support)

[dcutugno]

Tom can ypu post here the 385F version that do not have the problem?
I haven't the backup.
Also i have problem with the MCP 418 not releasing brakes after a dual autoland!

[Tom Stian Bjerk]

Here it is..

The CDU 385F and MCP 414

[dcutugno]

Thank you! I will try after the week-end.

[Jan Pemöller]

Happy Easter!

New Builds are up for Airbus-Users!
Lets hope that we "boing guys" will also get an easter egg ....

Normaly that is PM´s surprise every year ;-)

Best regards
Jan

[yoss]

Tnx for the files,Tom
And which database set are u using?

Hi

Using the 0703 Cycle from navigraph.. It seams to work ok.. Better then buildt388 anyway :=)

Best Regards
Tom Stian Bjerk

[Tom Stian Bjerk]

Damn.. seams that the 385F also is buggy :( I have some older version that I can try..

[michelmvd]

I think the newer builds very specially adapted for the new Navigraph NAVDATA. Looks strange to me that older builds will work correctly with the latest airac cycles data.
I had contact with Enrico, before the weekend regarding the Mach Speed problem in the Aerosoft MCP 747, and here the solution was to go the US regional settings in windows xp.
Enrico informed me, he is also looking further into the CDU problem. I did also a test by using the US settings there, but no solution here. Problems were remaining the same.
