RNP Values Lower than .3

[CRAZY LEGS]

Going into KSUN next week and have a question about the RNAV approaches. Last time I was there all they had was the old Hailey BCN aproach. Anyhow, a couple of the approaches have RNP requirements of less than .3

My questions are-

what aircraft/avionics packages are certified to less than RNP .3?

What satisfies the special crew and airplane training to conduct the approaches for part 91 ops?

Someone will come along and correct me if I'm wrong, but I believe the airlines are the only ones approved for SAAAR approaches. There are no bizav nav systems certified that are capable of < RNP.3

Actually the G550 is capable of RNP .11. There is an RNAV approach into DCA that requires this. Just shot it last month in the SIM. I believe any aircraft with the Planeview Epic avionics package is capable of this. At least that is what our SIM instructor at flightsafety told us..??

The planeview system may be certified to below .3, not sure on that. I know that the airlines are the only ones certified to fly those approaches though. As im sure you know it was all pioneered by alaska airlines back in the 90's.
The reason bizav is not certified, is due to all the restrictions in place to get certified. I believe a company has to do so many for currency purposes as a whole and it is a specific # rather than a percentage, meaning unless you have a very large fleet, its not going to happen.
I could be totally wrong...
Check out the faa's site and do a search on them, there is a lot of useful information.

Operational Approval to Conduct RNP SAAAR

Greetings--

As far as current aircraft operating below RNP 0.3--the 737 fleet is the only current fleet operating below RNP 0.3. The important thing to note with RNP SAAAR (Special Aircrew and Aircraft Required), is that the procedure, the crew and the aircraft must all be approved for the operation. This is similar to getting a Cat II/III approval today.

The current method to gain approval to fly an RNP SAAAR procedure (approaches titled RNAV (RNP)) is to utilize AC 90-101. It will definitely be possible for certain business aircraft to be approved to fly RNP SAAAR.

Here's the link to AC 90-101.

Hope this helps...

The Gulfstream IVSP (which is equiped with Honeywell SPZ-8400 FMSs) is capable of these approaches. Even when the FMSs have the rather old version of navagation software (4.1), they are still capable of this sensitivity when in the approach mode.

The Honeywell SPZ-8000 series FMS is 1980s technology so I can't imagine that this is the only business aircraft/FMS combination able to fly RNP 0.3 approaches.

We've got the 550's but not the authorization to fly the approaches. It's my understanding that the Feds won't approve an application to do so. TC

Thanks for the good info guys. The application covered in appendix 7 of the circular looks like a bear. Thanks again

SUN- We go there regularly and have the same issues with aforementioned approval.

If you need some options and are not familiar with SUN, TWF is a good alternate as is JER.
