I wish to know the navdata if still to be Jeppesen and at when is updated, also if finalyy this time is "updatable"Thanks a lotAndy

The Navdata comes from many different worldwide sources. Jepps is only 1 of them. Jepps probably actually only covers about a 1/3 of all NavData accross the globe in reality. Bet you guys didn't know that.Once they put it in, it's in there. It doesn't get updated. I'm not sure what "cycle" you would call it. Maybe they can answer that better.For simmers we usually update our navdata through various web sources (navigraph, etc.) so we can have our payware aircraft FMC's, etc. current.In other words it works a little backwards when it comes to the sim. I know that doesn't help much if you were to say; try and update your default FS GPS. It could be possible I suppose that MS may look at some sort of update feature in the distant future, but it's not an easy task considering all the sources needed to maintain an 'actual' worldwide d-base.Jepp's alone would charge somewhere in the neighborhood of about 10-15K for each navigational device to the developer + about $30.00 USD for each 'cycle' to the user.Clear as mud?:-)

We've been told the navdata is April 2005.And just like FS2004 - updates can be done - but no one has been willing to do more than an airport at a time.

Regg,Navdata is alot more then just airports. Airports are only a small part of the big picture. For that matter, Airports, fixes, navaids, and even terminal procedures make up only about half (maybe a bit more) of the actual data.I'm sure Richard can attest and elaborate on that.For simmers we mainly use the ones I just listed, but to do it right takes a alot more, in addition the enormous tasks of just getting the stuff I just mentioned in there correctly. Then after that your device has to make that data work and display properly.There's alot of stuff that the normal user doesn't see, so before we dismiss it as easy to do, think a bit about what you're asking.

Jeff,I'm aware of what it takes to build new approaches and airports with working approaches for the GPS, user aircraft and AI aircraft in FS.The FSX SDK is even better than the FS2004 SDK - but you really need to understand how approaches are built in the real world, not just how they are used.Updating the data can be done, but no one has done more than one airport at a time to my knowledge.Addon files in FS2004 work very well to replace default approaches, add new navaids, waypoints, etc.They appear to work in FSX.There is no need to edit the default files for an update. But it would be a massive, and probably very expensive, project.

Regg,I think we're on the same page here and I'm not sure what you mean by not understanding about how appr's are built in the real world...ROFL, but anyways, I think we're starting to get off center, so I'll not address that.I'm also not sure what you mean about no one has done 1 airport at a time and to what devices default or otherwise you mean.I'm also not sure why you would need to edit the default files for any user so long as you could interface their device with your own data base, unless you're talking about something that is completely and physically missing, but then again it would matter because the data has the relevant location anyways.Whatever the case, the original poster probably has no clue as to what you or I are talking about, but I hope we answered his question about the navdata for FSX..LOL.

I would say yes, I've an idea ;-)The point is that since I use (and more people like me) FS as a complementary IFR training, we would like to perform the update procedure as require with updated chart.I konw that Jeppesen isn't the only one to make navdatabase, I referred to them because in the past the database was based on Jeppesen dataCiao Andrea

Andrea,Yes, I think I see what you want to do. I doubt you refered to Jepps as a source for Navdata for simming because having just recently talked to them, they do not make current data base cycles for simming use, "yet". They only allowed MS to purchase a 1 time cycle (from what I gather). If you're talking about charts, then yes, you can always buy current charts or even sim charts.To do what I think you're asking would cost roughly 10-20 THOUSAND US dollars for EACH nav device (i.e custom data base-i.e, GPS, FMC, etc.) to the developer, then each user (you) would have to pay between 10.00-30.00 USD (depending on what and how much navdata types are included) for each monthly cycle if they wanted their GPS, or FMC's to be current also, which they would get from the Jepps web user site and it would automatically get filled.In other words, Jepps makes a data base custom to the developer's nav device they are developing (FMC, GPS, etc.). That's why it's so expensive (or not depending on how you look at it). The user, if they have that device logs into Jepps, selects their product, just like real pilots do, and you download the new cycle from Jepps, and you're off.To have updated navdata doesn't rely on the sim per say as much as the nav device you're using, unless...that device pulling from the existing MSFS database, which is like Reggie said was from April 2005.Sorry to be broad stroke here, but I don't have any idea as to how exactly you're flying. Are you using payware aircraft or default? I'm assuming you're using the default GPS from the sounds of it. If this is the case, yes, you're outdated from the start.

Do you Know the actual FSX on which navdata is based on?

Not entirely. I know that Jepps was 1 out of several worldwide sources.Jepps does not actually cover alot of the world, which I was also surprised to find out.

No one from ACES knew the exact cycle of the navdata in the posts they made - just that the airport, waypoints, navaids, intersections and approach data came in to MS in April 2005.We can code in approaches if there are changes to an airport such as a new runway, new ILS, or change in runway designators, or a new procedure, etc.A brand new airport or a default airport can be updated to the latest cycle. Several have been for FS2004 - with Jim Vile doing the best work.Jim has even been able to extend the approach out into the STAR and bring AI and user aircraft into Atlanta on MACEY2.I've pulled the XML code out of FSX for a couple airports - and used that approach data for new runways successfully in FS2004.Many folks want to alter the default APnnnnn.bgl files which hold airport specific information and the default NV9xxxxn.bgl files which hold navaids. Altering the default files is not necessary to make these additions, because FS2004 has a rather sophisticated built in layering process, if the files are placed in the correct stock folders.We could not in FS2004 remove a Localizer, or other default NAVAID.We could add change frequencies. But in many cases, the best result was to change the frequency of a decommissioned navaid and decrease the range to the minimum.The FSX SDK provides a bit more information about the approach coding than FS2004 - much of which we've already figured out - but hopefully more people will take up the process of updating procedures for the default FS GPS and ATC.

Reggie,Am I missing something here?? LOL. This guy isn't designing or anything, he's just flying, unless I got the whole thing backwards.

That's how I read the questions - flying.But just letting him know that is is possible to update an FS2004 airport - with a couple caveats - to the most current data which FS can use.And it looks like FSX airports can be updated also.But to not expect to have more than a few airports updated to current data.I'm sure the entire FS world could be updated - but the cost would be more than anyone could affort, and the download would be massive.If the goal is to have the updated data for a couple airports - that is within the capability of one person to learn and do.If the goal is world wide updated data, something which replaces the FS default navdata and ATC is probably necessary, at an additional cost.It also depends upon how detailed he wants the data. If he wants the holds, misses approaches, transitions, etc which are built into the default airports, or just an approach final.

The cheapest and best way right now is through the new Navigraph that Richard teamed up with, IMO. It's only a few dollars for each cycle and should cover what he needs for right now, less the terminal procedures which are on the way.

Super Flight Planner has the ability to pull out all the stock waypoints and navaids from FS9. This could be used in a comparison with any available database such as the navigraph and waypoint and nav data additions (don't think there is a provision for exclusion) developed. I suppose the same could be done for FSX if bglxml were updated. In FS9 you also have to place scenery objects but that could probably be automated too.scott s..
