Regionals with RNP AR
 

Any regionals with RNP AR? YX is in the process and will be in our manuals Oct 1.

Congrats

I know OO has some, assume QX has to as well.

I'll be putting my app in asap for them rnp approaches. Qol thru the roof

Qx has 0.1 on both fleets

OO has .3 on the 175.

Any LPV certified regionals?

Something that has always bewildered me (but honestly I don't know enough about it). You can get a crapped out C172 or Cherokee with a six pack and Garmin 430 Waas and shoot LPV all day long, yet a brand new CRJ or E175 "can't"

That's because that brand new CRJ or E175 still doesn't have WAAS.

I think Horizon is LPV equipped, if not certified. They even have cat3 autoland on the 175’s and I believe they fly cat3 on the dash too.

Transport category avionics upgrades cost $$$$$$.

When the wx rolls in at the hub, the RJs get cancelled first anyway so most majors don't want to pay for a capability that's rarely used.

AS sends OO and QX to Alaska, so that's a different deal.

Nice. Anywhere you regularly fly 0.1?

Thanks?

The issue isn’t getting one new airframe certified.

It’s every airframe and every pilot and for what? Every hub has a cat ii ils

Lpv is great for a pa32 flying to a 4000’ runway someplace with self-serve 100ll. Doesn’t make much difference to an RJ

Funny thing is our CRJ700/900 Next Gens have LPV capability... we’re just not authorized to use it.

Not in the US at least. In different parts of the world RNAV and RNP AR approaches are starting to become popular especially in mountainous terrain where curved final approach segments are needed.

Q400 has LPV, RNP 0.1, and handflies CAT3 using a HUD to 50'.

E175 has CAT3 autoland with 50' DH, RNP 0.1, but no LPV

Almost all outstations have an RNP approach. All high terrain airports we use it, the only places we almost certainly never use it are big airports with a lot of arrivals because nobody else has it.

It was annoying because in training they have you flying RNP approaches into SEA over and over again, yet in all my years on the dash I never once got approved to fly it on the line.

Cool, thanks
.3 RNP is such a nothing thing someone in the FAA must have fought to put AR on it.

I believe the Envoy e175s use LPV technology to LNAV+VNAV minimums, that’s why we use ‘APR’ mode on those approaches.

LPV and LNAV/VNAV are two different things. You need a WAAS equipped aircraft to fly LPV, highly unlikely Envoy’s 175s are equipped. Hopefully you’re using “APR mode” on ALL approaches with vertical guidance.

Who cares about RNP, yeah it’s great to have, but like one of the other posts indicated it’s unlikely you’ll actually be “cleared” for any RNP to a major airport. I’m not too sure why YX deems it necessary to spend money on this, as you’ll only really use it flying out west, especially the PNW, which they’re not flying.

A few weeks ago we got approved for the Z to 16R from VASHN. Couldn't believe it.

RNP will be used every time the weather goes down in DCA and 19 is in use. As it stands the LDA gets you down to 800'. Last summer when that localizer went underwater the other one left us at 1100 or 1200, cant remember. Lots of go arounds and diversions that could be avoided with RNP.

Seems like a lot of work and money for primarily one airport. It is interesting they’re investing in it since we’re an east coast airline.

Depends what the supporting major has.

Couple days a year cancelling all rj’s into dca when the majors are flying is gonna get attention

Not at a regional now, but every time it's nice in SFO we get the rnp visual there.

The major calls the shots on nav capability, and then pays for what they specify. In addition to equipment and related MX, typically an entire pilot group needs to be RNP trained, even though only a handful might ever do it.

Up to the major, but they also consider arrival slots... those go down when the wx goes down and they always canx the RJ's first anyway.

Our 747's now have two WAAS GPS's, but they are for a different requirement.

The cost of not getting in is vastly higher for a cargo widebody, and any 74 operators probably go to some under-developed places.

Those pesky Europeans like a lot of technology to cross the Atlantic on the NAT Tracks. I rarely do an RNAV approach, 99% ILS even into places in Africa. A 747 requires a decent airport, and decent sized airports have ILS's no matter where they are located.
