Required Navigational Performance

[mcmbenjamin]

Does anyone know why some have RNP (Required Navigational Performance) while others do not? Does not even seam to a type issue. Odd really.

I guess it comes down to the aircraft in question, the equipment it has on board and it's performance limitations.

You have lost me. What is RNP and how do you know what has it?

Thanks for the link (which was useful) but I wondered why the thread started? And why in the VS General Discussion area? Can someone explain the relevance to VS?

Thanks

Darn good question, however we are at a loss to figure out where to move it to [?]

Without the pretty LSoM here to guide I am afraid I am kind of lost...so till the fair maiden returns what the heck, we are open to ideas [y]

OMG..Paris Hilton has taken possession of GJ's mind...thats hot [:0]

OK, I am sure that the long term users of this board took a shipment of some dodgy substances as this thread is very surreal. I was just trying to work out why Benjamin asked the original question. It is almost as if the first post in this thread was split from another that make sense of the whole question.

I'm not criticising the post in any way, I am just interested in what generated the original question. Please enlighten me as these things stop me sleeping

Paul, sweetheart. We are all just as puzzled so just have a nice mug of warm milk and have a nice sleep

Why did I ask the question? Hmmm, Well I did not know the answer and some people that visit this site know about VS operations and may know the answer. Logical. Sorry not to ask about CH access, sleep suits or how to score a Z fare. And the best; Is there Upper Class Suite and now the new PE on my flight? Well I like my question: Does my flight have the proper navigation equipment and why the different equipment on the same plane type? See an operator (VS) would have different dispatching rules based on the equipment.

RNP allows planes to be stacked closure together and provides slightly better position awareness; sorta like RVSM but different. When an airplane files a flight plan they state their type of plane and the equipment onboard. Something like A343/W or A343/Q. Well the /W and /Q are equipment codes, main /W means just RVSM and /Q means RVSM with RNP plus Mode C transponder. Basically /Q means that the plane has slightly better navigation equipment.

I noticed that some VS flight on FlightAware.com on the A343 are /W while others are /Q. I was wondering if there is a reason or did someone forget to update the flight planning software (more common). Really a question that I thought would lead to an interesting PM or reply but has lead to OT land...

I do try an value and expand the focus from the above wing (in cabin/airport) view to possibly viewing an airline operation as a larger system.

Ben, no-one was criticising you for asking the question, but go back and read the opening sentence and indeed the rest of the post and you will see it does not make sense.

Some what? Sleep suits? Amenity kits? Planes? Pilots? Cabin crew? Log books?

If you had asked it the way you have done in your latest post we would have understood it better.

We might not have been able to answer but it would not have seemed like gobbledey-gook

Err, well said that man.

Have you been experimenting with the contents of your last amenity kit by any chance? You know, a little mix-n-match....[}:)]

I've noticed on Flightaware that the same flight on the same day operated by the same aircraft may depart as /Q, and refile enroute as /W, or an inbound sector will be /Q, while the return is /W.

I think this may depend on the origin of the flightplan - i.e. did the VS planners file it (in which case it's probably Q), or did an Air Traffic Service Unit file it on behalf of the aircraft (which seems to be the /W).

A good example of this is the ANZ1/2. If you look at the ANZ2, you almost always see the whole flightplan for both the AKL-LAX and LAX-LHR sectors, and they are both /Q. That leads me to believe that these are the original flightplans filed by ANZ despatch/flight ops.

ANZ1 LAX-AKL is also /Q, and the whole flightplan. The LHR-LAX flight, which will have been operated by the same aircraft is usually shown as /W, but usually isn't the whole route either, usually just the segment from where the flight re-enters radar controlled airspace, which I think shows that this flightplan was generated by an ATSU, rather than ANZ, and the aircraft probably isn't operating to RNP requirements in the US airspace.

I'll bet you it's /Q when it leaves LHR.

Even though VS operate a number of the same type of aircraft, be it 744's, A346's, with the exception of the 346's VS picked up these aircraft from various sources, I am sure if the 744's had been ordered directly from Boeing they would all be close to identical, however with them coming from say the canceled Alitalia order they would of come as the original operator ordered them...unless VS decided to upgrade them at a later date.
