What are the aircraft equipment/systems eligibility requirements for Airbus A320 airplanes to operate in RNP 2 airspace?

1$\begingroup$ In which country? See page 32-33 of this ICAO presentation. For India, this operating circular is relevant, for Autralia this is this one. RNP is not an airspace, but a navigation mode like RNAV. All RNP modes and RNAV are part of PBN. $\endgroup$– minsJul 31, 2016 at 11:03

$\begingroup$ Are dual navigation autopilot and GNSS systems required for RNP2 despatch purposes? $\endgroup$– user175574Jul 31, 2016 at 13:13

$\begingroup$ @user175574 No, a single autopilot would be fine, and in fact I suspect that no autopilot wouldn't disqualify for RNP 2, at least in the US. Also, GNSS wouldn't be required in MOST airspace, because DME/DME updates are plenty accurate for RNP 2, if/where there are enough Navaids close by. Over the ocean, then yes you'd need GNSS. RNP 2 isn't very demanding -- essentially any A320 has more than enough to meet the requirements for it. $\endgroup$– Ralph J ♦Jul 31, 2016 at 14:13

According to ICAO/EASA till 12/2015 Version. And from Airbus getting to grips with modern navigation.
Regulatory Authorities have published standards for specific airspaces. Provide certification and operational requirements for Basic RNAV (RNP-5 Type) and for Precision RNAV (RNP1 Type) within European airspace (refer to Annexes 5.1 and 5.2 at the end). FAA Order 8400.12A addresses RNP-10 operations in oceanic and remote areas (refer to Annex 5.3 at the end). Also RNP AR required equipment is specified in several sources and the FCOM manual of airbus. In addition for RNP 2 specific terminal and approach operations the requirements are specified on the approach charts of airports that implementing it.
Most of the operators/airlines are using the standard required equipment for RNP 1.
According to FCOM A319/A320/A321 FLEET / PRO-SPO-51 P 8/10 The minimum navigation equipment required to enter RNP 1 airspace is:
‐ One FMGC
‐ One MCDU
‐ One GPS
‐ Two IRS
‐ One FD in NAV mode
> ‐ Two NDs (the temporary display of ND information via the PFD/ND switch is permitted on one side).
Some helpful information also about RNP 2 you can find also here: http://www2010.icao.int/NACC/documents/meetings/2013/pbn2013/ops7-en.pdf
Moreover Airbus company under PRO-SPO-51 P 5/10 in FCOM refers as RNAV1(2) so it takes exactly the same equipment for RNP 1.
Let me know if something is different, or if you have different information from another specific-related documentation.
