an introduction to performance based navigation (PBN) and RNP
I was doing some online training and was sent to this Eurocontrol link. I am not sure that I could past the 20 page document here but the link is provided for those who would like more info on PBN and the differences between RNAV and RNP. Yes, its Eurocontrol focused, but the ideas and concepts are universal.

Re: an introduction to performance based navigation (PBN) and RNP
Am considering whether it would be worth my while to present similar type courses at obviously the non-$ prices but it would depend on the interest. Ideally I would also link it through a local training organisation for the accreditation at the SITA etc. So who's interested?

I am intereseted. I have the equipment in my plane to do GNSS approaches, but have not done the course yet.tansg wrote: ↑Thu Jul 04, 2019 6:48 amAm considering whether it would be worth my while to present similar type courses at obviously the non-$ prices but it would depend on the interest.

I've done practise GNSS approaches in VMC, using my GTN650, Aspen and the autopilot. Works great. With all the beacons disappearing it will become a necessity.
I'll be visiting Aero Africa today and inquire there as well.

Re: an introduction to performance based navigation (PBN) and RNP
sg for the record, yes I would be interested in a PBN course. I come from an RNAV 1 and basic RNP background but retired before PBN really kicked in so I have been left behind.
Like Iceberg I have a GTN650 which is crying out to be used more and I find that even in VMC PBN makes sense to find unfamiliar airports with IFR approaches.

I'm installing a GNT 650 this week in our 235 and would like to know if the aircraft itself needs to be approved for Rnav approaches

Yes it does. I'm busy with mine through Century Avionics.Cornell Blok wrote: ↑Mon Aug 05, 2019 1:44 pmI'm installing a GNT 650 this week in our 235 and would like to know if the aircraft itself needs to be approved for Rnav approaches![]()
In the meantime I did the RNAV course through Simuflight in Midrand - I can recommend them.
Did a practise RNAV approach at FAWB in VMC with the knowledge I gained on the course, the plane flew it beautifully on the GTN through the AP.
At FAWB the VOR/DME and WB NDB are out - that leaves only the RNAV approach. Sign of the times.

So glad to be reading this after our previous discussions on GNSS approaches.

Re: an introduction to performance based navigation (PBN) and RNP
I just stumbled across this thread. Tansg, do you have any info or insight how this would apply to ATC separation? Reason I'm asking is because I attended a PBN course almost a year ago but found it to be more specific to the requirements to comply with PBN/RNAV and not about separation from an ATC point of view. Any thoughts on this?

Got no "Rydaars" in at work today to check with but will post as soon as I have checked with one of them.MemyselfandI wrote: ↑Tue Dec 03, 2019 1:44 pmI just stumbled across this thread.

Re: an introduction to performance based navigation (PBN) and RNP
Sorry I took so long. It is contained in ICAO Doc 4444 PANS-ATM Chapter 5.4 Horizontal Separation specifically
5.4.1.2.1.3 By use of different navigation aids or methods. Lateral separation between aircraft using different
navigation aids, or when one aircraft is using RNAV equipment, shall be established by ensuring that the derived protected
airspaces for the navigation aid(s) or RNP do not overlap.
5.4.1.2.1.4 Lateral separation of aircraft on published instrument flight procedures for arrivals and departures.
5.4.1.2.1.4.1 Lateral separation of departing and/or arriving aircraft, using instrument flight procedures, will exist:
a) where the distance between any combination of RNAV 1 with RNAV 1, or RNP 1, RNP APCH or RNP AR
APCH tracks is not less than 13 km (7 NM); or
b) where the distance between any combination of RNP 1, RNP APCH or RNP AR APCH tracks is not less than
9.3 km (5 NM); or
c) where the protected areas of tracks designed using obstacle clearance criteria do not overlap and provided
operational error is considered.
Note 1.— Distance values contained in a) and b) above were determined by collision risk analysis using multiple
navigation specifications. Information on this analysis is contained in Circular 324, Guidelines for Lateral Separation of
Arriving and Departing Aircraft on Published Adjacent Instrument Flight Procedures.
Note 2.— Circular 324 also contains information on separation of arrival and departure tracks using
non-overlapping protected areas based on obstacle clearance criteria, as provided for in the Procedures for Air
Navigation Services — Aircraft Operations, Volume II — Construction of Visual and Instrument Flight Procedures
(PANS-OPS, Doc 8168).
Note 3.— Provisions concerning reductions in separation minima are contained in Chapter 2, ATS Safety
Management, and Chapter 5, Separation Methods and Minima, Section 5.11.
Note 4.— Guidance concerning the navigation specifications is contained in the Performance-based Navigation
(PBN) Manual (Doc 9613).
This is carried on further in the Chapter for various scenarios.
ICAO Circular 324 provides the background information as to how these seperations were derived.

Thank you, I have access to those docs, much appreciated.
