HiWill the NGX be able to fly RNP AR approaches, including RF segments (curved legs)?.CheersDavid

Yes, that is also something I hope it will be capable. The best would be full ARINC 424-19 compatibility out of the box. Jan-Paul

Man, you guys talk about all these features and have no friggin clue of what each thing does..

Can't say I'm a fan of the ARINC terminology. They make manouvers seem a lot more complex than they are."TF - Track to a Fix". Oh, you mean fly from this defined point here to that defined point there following the GC route? Sure.All I care about is will the FMC do everything the real-world one does from the pilot perspective?Best regards,Robin.

Technically, it is impossible for an FMC in FS to operate exactly as it can in the real world, although it can get very close, and one would imagine that's what PMDG will do.

Airports here in Oz are starting to use RNP quite widely. I believe Qantas' and Virgin's 737NGs take advantage of the RNP procedures when possible. For some airports, it is the standard method of departure/arrival now. I think Jetstar's A320s/pilots aren't properly qualified for the job (yet), at least that's what I was told half a year ago or so.Cheers,Rudy

OK then - "within the limitations of a desktop computer". :(

Most likely certification of the aircraft. They probably lack a piece of equipment or a software update to use it. From the pilots angle there is little to it - monitor as you would any other type of automated approach.Best regards,Robin.

I should think that within the realms of what actually is possible, PMDG will pull that off.

I hope so!Best regards,Robin.

Jetstar pilots are progressivley been taind for RNP during their sim checks. It is normal for use in NZ especially Queenstown and is used all over Australia, especially gold coast and brisbane. Qantas have been using the technology for a while now. The funny thing is i know the abouve info but have no clue on how RNP works or how it acctually differs from normal operations, anyone wish to explain to me?

RNP is basically a tighter variance specfication than GPS. The chart will specify the variance such as RNP 0.3 or 0.1, which is a statistical measure of error (given as a RMS value I believe with better than 90% confidence). Since a variance of 0.1 nm is only 608 ft, this allows lower minima. Many of the major airports in the US (and in my sidstar collection) have both RNAV (GPS) and RNAV (RNP) approaches. Verticle guidance is included, but they are still classified non-precision. However, there is a new type of GPS-based approach at KEWR called a GLS approach and the verticle guidance and runway environment (obstructions, lighting, markings) are certified as precision approaches with ILS CAT I minima. Pretty interesting.There are primarily three things missing from the PMDG products today that make simulation of a RNP approach impractical: No course deviation indication for pilot to monitor as required by FAR certification, the lack of a suitable RF (radius to fix) leg implementation (pseudofixes are used for form arcs but this is sloppy) and lack of a vertical path definition for cross at and descend through (the FMS only cross at and maintains at fix instead of descending through).I know the wizards at PMDG are working on something, but I have no idea what it is and I have my fingers crossed.

Rummor around the office is that a westjet pilot has been helping out with the majority of the FMC Programming. Can anyone from PMDG confirm weather or not this rummor is true? Greg Keath

We do not reveal our tech advisors unless they wish to be revealed themselves. We have several pilots from several different airlines helping us.

Quite right too. Not everyone wishes people to know their business, and so long as the gen they provide is good, we don't need to know who it was that did so.Al

Alan easy there fella! Its not that I was asking for a name or anything like that. I wasnt trying to poke and pry at somthing that is not my buisness. It was just a simple question and if PMDG doesnt release that information thats fair enough for me. Thanks Ryan for your reply are you at all able to say which airlines these pilots are from? If not I totally understand its compleatly out of curiosity. Greg Keath
