RNP

the lowest rnp value is .1 and the capability to fly certain rnp values is based upon the equipment in the aircraft rather than coverage. rnp procedures really are pretty cool. i design them rather than fly them. if i could, i'd show ya'll some that we're working on that have up to four different routes on the same approach with a bunch of rf legs snaking around.

Quality content, huh? Okay, no monkeys humping in this one.

SWA is fixing to roll out RNP procedures on an introductory basis for flights between DAL and HOU in Jan 2008.

Trial flights were/are being flown this month. If all goes as planned, more cities will be added monthly (LAS, ELP, & PHX?)

A big hurdle for realizing RNP savings is other non-RNP traffic, which probably makes DAL-HOU ideal candidates.
 
My student caught me about a month ago when we were reading the approach brief and it said some junk about RNP .3.
i said, "It has nothing to do with our approach or our airplane and you won't have anything to do with it for quite a while.....and I'll get back to you on what it is when i find out."
....uhhhhh

Nice

That is about how I felt the first time a student asked me about GPS approaches. The planes we had were not equipped with any IFR capable GPS and out of the blue this new fangled Garmin equipped plane shows up.

I had a lot of studying to do.

GPS is a type of RNAV. So is LORAN and INS/IRU.

RNP is a measurement of RNAV tolerances, both in terms of position and percentage of time.

RNAV procedures are predicated on an aircraft meeting a certain level of RNP.

The original RNAV were computers that calculated a very very accurate position based on 3 separate DME stations. Range only or rho- rho fixes gave an accurate and unambigious position.
