Will PMDG provide 737 Inertial nav before BBJ is released?

Recommended Posts

Just wondering - I know PMDG are working on integrating a functional Inertial Reference System for the 737 lineup and I wonder if this will be modeled before the release of the 737 Boeing Business Jet jet or as an upgrade requiring future purchase of the BBJ package. I'm thinking the latter but just wanted to ask. Thanks.

I would rather see them put all their effort into the 747-400 instead.

I would rather have a totally complete 737 first instead of only partial system simulation :)

I agree with Bruce :) A complete NG737 before the next project would be best. IMHO :)

Here, here :) I hope PMDG will shed some light on this soon!

I think this was discussed early in production in another thread. A search of the archives might bring it to light. I think the conclusion was that not a lot of people were going to want to sit around for ten minutes while the INS spooled up - thus probably not worth the programming time. I could be wrong - advancing age retreating memory - but I seem to remember this. Best,

I quote PMDG with this: "if we can do it, we will do it and if we can't do it, we will not develope it", or something like that.And with the B744 comming they maybe will try to develope it.

Why should they only try to develop it for the 747 instead of really doing it. I don

Quote R Randazzo/PMDG5) We have deferred installation of Inertial Reference System until a later date. Not because we couldn't make it work, but because we did not feel we had adequate time to get it interacting properly with the rest of the airplane systems that it supports. We'll have more information for you on this topic in a future update.

I hope they do provide it in an update, then it would really be a complete simulation. Not that I don't love it as it is :-)Andrew

I do too, I just wish PMDG could offer a little insight into what their current plans are regarding all of this. I'm guessing that they are going to wait until they release the BBJ and just include an IRS as part of that upgrade package - thus IRS functionality would 'trickle' down to our previous -700 and -800 series installations just like the current -800 package upgrades functionality to the previous -700 series.This seems to be their current business strategy but I'm just conjecturing here.

A quick question.How would an IRS benefit us in the virtual cockpit? I would be interested to know how it would change the way we navigate at present?please let me know your thoughts, cheers, Nick

In fact, really all an IRS system would amount to would be some FMC input, and some overhead switch twirling during preflight.

Hi Nick,It would just be a lot more realistic to be able to go through Inertial Nav alignment during a preflight for one thing, rather than have the attitude display simply pop on with the battery switch as it does now. To me the panel just feels too 'watered down' without it, even with all of the other features. In fact, having all the detail the panel has now makes the lack of a functioning IRS stand out more in contrast.In real life the IRS system provides attitude, heading, rate of climb, yaw damper input, groundspeed, and wind speed/direction information. It would be much more realistic to be able to simulate not only alignment/shutdown procedures but also the possibility of implementing failures for procedural training.But as to your question regarding navigation, modern 'glass cockpit' navigation systems use sensor blending to derive position information. Essencially the computer has an established hiearchy of navigation sensor data it uses to derive positional information. In the case of the 737NG, position information is polled from GPS, Scanning DME, and Inertial Nav in that order of accuracy. So in answer to your question a functioning IRS would not really change the way you navigate, only make certain other procedures associated with cockpit managment and potential system failures have more realism. Cheers,

Lol, geez Fred, why even have battery switches, hydraulic and fuel pump switches, air conditioning packs, ect. if you simply consider all of this simply switch twirling during preflight?It's the lack of the total immersion factor that the default Microsoft panels have that make realistic panels like PMDG's 737 appealing to the masses, wouldn't you agree?

Cool thanks to Fred and Bruce for the info, much appreciated.cheers, Nick

Bruce,I agree. With the high level of functionality of the PMDG737, it just needs an IRS even more. As much as I'm looking forward to the 744, I hope PMDG will keep their word regarding the IRS update for the 737.Thomas

Thomas and BruceI couldn't agree more!I have thought that I might be the sole person here who really wants the IRS fitted. For me, it's just like Bruce said: "watered down". Not to be rude, impolite or anything like that, just saying how I feel. IRS alignment, its monitoring and things you need to do in case of IRS faults are the essence of modern jet navigation. I feel the 700/800 series strongly needs the IRS to complement the otherwise well built system platform.For me, the idea of buying package after another to get added functionality does not appeal.with respect,Tero

I am trying to put a positive spin on this whole IRS thing: yea we dont' have it but all it would amount to would be some switch twirling and FMC input hehee.>It's the lack of the total immersion factor that the default>Microsoft panels have that make realistic panels like PMDG's>737 appealing to the masses, wouldn't you agree?Oh yea, thats what makes it appealing.

A valid and polite discussion about a thing many of us feel strongly about. If you don't, don't read the threads. Simple, really.Tero

I don't think I've stated my opinion before either, so I shall also state here that I think the IRS would be good to have in the 737 to make it a complete product, but many of us are realism fanatics. Yes, I am eagerly awaiting the 74, but the IRS would really make the 737NG a truely complete product. Personally though, the announcement I am really waiting for in the near future is the ACARS one - interested to see whether it will happen (probably not based on the long period between talking and beta testers receiving no news on the subject - Freddo said that ;)), and how it will be done if it does.Bye!Geoffrey BaleanCanberra, AU (YSCB)http://www.hifisim.com/images/as2004proudsupporter.jpg http://www.vozvirtual.org/images/pmdgforumsignature.png"Today is the tomorrow you worried about yesterday.
