Virgin - RNP Approaches Queenstown?

[Robot]

Do Virgin have approval for RNP arrivals at Queenstown NZ?
I read they were to have approval by the end of 2012 - we're nearly there.

[big buddah]

Yes they do. RNP arrivals and RNP approaches.

Thanks:ok:
Going next week (back seat).

RNP 1.0 or better?

[c100driver]

I thought that PacBlue were at stage two in certification. That is RNP 0.3?

[Sqwark2000]

Mt Cook does RNP0.3 approaches with it's averagely equipped ATR72-500's, so Virgin should be able to match that.

They'll need RNP-AR approval to do RNP0.11

As of 15NOV, Queenstown ( & Invercargill ) was designated PBN airspace requiring RNP1.0 for RNAV STAR & SID procedures. The STAR's & SID's extend beyond the 30nm transition for enroute & terminal modes.

Big delays and holding if you want to get in there IFR without PBN equipment.

I think he meant RNP 0.1

[minimum_wage]

The end goal for VANZ is RNP 0.1 but that is stage 3. Need 30 vmc approaches of RNP AR, then 300 more to a higher minima than the 0.1.(3000ft or something like that). Once these proving flights are done they will be granted approval for 0.1 minima.
Like Sqwark said the RNP 0.3 approach is able to be flown by virgin but the GNSS and AR are completely different in how they are designed and flown, not to mention the equipment required that an ATR doesn't have.

Vanz actually have an rnp-ar approval to .1 on the aoc now, not .3... .albeit .1 in vmc initially. Then phase 2 allows down to .3 in imc basically to the faf.
Correct need to do 30 rnp-ar approaches in vmc. These should be completed by feb 2013 all going well.
Squark, are you guys doing the rnav approaches or the rnp-ar approaches? Do you guys have inboard monitoring in the atr?

Not technically correct,
The GNSS approaches are able to be flown now and .3 is manually set in the box just as it is in any RNAV/GNSS approach but the RNP-AR approaches are different in that the rnp-ar has a manually set 125' vertical rnp value as well as the auto set .1 lateral rnp and requires operator approval and also includes an onboard monitoring system as part of the process- amongst other requirements, which is what we have so we can currently do the ar approach down to .1 but in VMC, the data from 10000' to minima is captured and retrieved from the box an then will be sent to caa as part of the process for the first 30.

If you check the charts the GNSS approaches have straight legs not radius to fix legs like the RNP-AR approaches, the ZQN GNSS approaches require a circle to land from minima, just like the BRAVO and the CHARLIE VOR approaches, the RNP-AR does not.

Standard RNAV's for us. We don't have a autocoupled VNAV ability and nil on board monitoring. The -600 was pitched as being able to do RNP app which we were keen on as ZQN is one of our bread & butter routes, but it's not equipped and no one else has done it yet (certification).

Our HT1000 GNSS boxes are coded for auto selection of 0.3 in app mode.

Yeah that's what I thought Nath. said on the rnp course I did a few weeks back, sounds like a cock up. Something about its not std equipment to provide rnp capability, but we can option it, oh and it hasn't been tested or something.

Heading in there this week...::uhoh:

Is there a mod to the FMC to set the 125' vertical RNP limit for the RNP-AR? The standard B737NG FMC has no facility to monitor vertical ANP deviation.

[minimum_wage]

Software update with NPS scales is required for it.

[Capn Bloggs]

125ft?? Our Baro-VNAV (much less accurate approach) limit is 75ft.

[minimum_wage]

The 125' for vertical deviation is a combination of 60' for static source and 65' for FTE. So you will get the NPS scales flashing amber at 65' FTE + 10 secs.

[Jet Man]

Where is the vertical RNP vs ANP shown. Do you get an FMC message if ANP > RNP?

[always inverted]

Where the glideslope and loc sales are normally, yeah you do get messages...

looking a bit high and fast there shags! Even the FMC appears a bit confused.
