SSJ100 gets RNAV 1 and P-RNAV certification

Russia’s Aviation Register of the Interstate Aviation Committee (AR IAC) has issued a Supplemental Type Certificate (STC) for the Sukhoi Superjet 100 (SSJ100), which confirms that the type can perform flights under Area Navigation in RNAV 1 and P-RNAV systems.

Area Navigation (RNAV) is a navigation method that allows aircraft operation on any desired flightpath within the coverage of ground- or space-based navigation aids or within the limits of the capability of self-contained aids, or a combination of these.

When operating in P-RNAV or RNAV 1 air space, the true position of the aircraft can be located within 1 nm (1.85 km) against the intended flight path during 95% of the flight. Thus, the extra accuracy of navigation ensures improved air traffic service.

Sukhoi Civil Aircraft Company (SCAC) is now undertaking measures to reach EASA certificate for P-RNAV and RNAV 1 as well as to expand the operational scope of the SSJ100 to provide extra accuracy at the approach stage of a flight.
