AIRAC cycle 2313 is 20 degrees off real world!

I noticed this whilst flying on VATPAC Australia last night.

The runway I was approaching was around 20 degrees off the heading I was flying.

My Nav Display showed in the wrong location!

I was on the correct heading but it showed I was on an angle to the runway, which I wasn’t!

I’ve flown planes this evening and it is still out.

How can I fix this?

I have 2313 installed.

Thanks
Grayson

Hi Grayson,

Welcome

So that the support team can help, please post details in FAQ - Information requested when posting an issue.

Hi Grayson,
thanks for the report but how should we check this or reproduce this, without knowing on which airport, on which runway and on which approach does this happen?

Also which addon/aircraft has you used and last, do you use the stock scenery or a 3rd party scenery?

This basic requirements are necessary to know, that we can try to reproduce it.

Thank you
Richard

Wow how quick to respond!

Attached is a pic showing the B77W ND screen.

I’m at NZAA on Ry 05R.

Ry heading is 052 but ND shows the extended centreline as 030!

I’m using the same scenery I’ve had installed for many years.

It happened at a fly in at YSSY last night. The runway was showing on the ND 20 degrees off its actual heading.

Which caused dramas trying to fly the ILS!

Nav data from you has always been correct but since I upgraded to 2313 its gone wrong.

Thank you

Grayson

Thanks Grayson,
what is the B77W? Is this a stock aircraft, a 3rd party aircraft? Also you can confirm that you´re using the stock NZAA scenery - so no 3rd party scenery for NZAA?

Last, when you try the same with ie. the stock A320 NEO - do you have the same effect?

cheers,
Richard

Apologies

77W is Boeing 777-300ER.

It’s third party plane but I’ve had it for almost 20 years.

Before 2313 it worked totally fine. Always has done.

I use third party NZ Scenery but I’ve had it also for around 20 years.

My Sim has always functioned completely fine.

Using standard A320 the runway offset is there.

I’ve been with Navigraph for a while and never had an issue.

The 20ish degree offset means I simply can’t fly into airports I have done for many years!

I’d it possible for me to download older data to remedy my issue?

Not for public release just to fix my Sim.

It’s 2333 here in NZ. Late bed time!

Hi Grayson,
but you can´t use the addon and the scenery for around 20 years - the MSFS is available only for 4 years and the addons and sceneries are not compatible. So, can you confirm, that you are using the MSFS?

Please, to avoid some more questions and to avoid some misunderstandings, please follow the link, posted by Ian - that we get really all information what we need.

Here again the link - we need really ALL details:

Thank you & good night,
Richard

My apologies.

I will go to your link

Grayson

I’m still using FS9!

Its run superbly for years for me.

Hence the long time having add-on scenery.

I saw this post regarding a similar issue.

https://forum.navigraph.com/t/airac-cycle-2312-rev-1-for-captain-sim-is-bad/14290/2

2311 will be the last perfect nav data for me too.

Is it possible to go back to it? Just for me not a public release?

I’ve spent quite some time Googling for an answer and there just isn’t one. There are many posts on blogs about heading irregularities as I’m having!

There are different causes for that in FS9.

First check if your registry entry is ok and fix it with following tool:

Second step (Root cause is bad scenery)

If the issue is still present, disable all add on scenery and reenable them step by step to find the bad scenery that can cause magvar issues worldwide.

I shall give that a go!

I’ve been on FS9 since it came out and never had an issue!

Is it possible to be emailed an earlier file? 2311?

Hi Grayson,

No thats not possible, but I will check the data between 2311 and the current one to eliminate an data issue. Will come back as soon as possible.

Which dataset do you install for this addon?

Cheers,
Richard

I understand.

2313 I update a couple of days ago.

Once installed I got the 20 deg off issue I’ve never had before!

Which dataset do you use for your addon?

Cheers,
Richard

Navigraph dataset??

I just looked at your program.

2313 Rev 1

No, which data do you download and install for this specific addon. Every addon has a own dataset. To compare the cycles, I must know which data I should compare with what.

So, do you download the PSS dataset, the PMDG dataset, the iFly dataset, …

Post a screenshot of your FMS Data Manager and show me the line on the Addon page, which you are using for the updates. Thank you!

Cheers,
Richard

Dummy.

The four I get are;

Feelthere Embraer Regional Jets
Flight1 ATR
PSS Airbus/Boeing/Dash
QualityWings 757, Bae 146

The pic I sent other night was of PSS 777-300ER Nav Display

Ok, I will check the PSS dataset then … thank you!

Cheers,
Richard

Awesome ta.

I’ve had Navigrpah for a wee while and never ever had an issue!

But with 2313 its gone 20 degrees off.
