Regulation (EU) No 965/2012
Aircraft shall only be operated in designated minimum navigation performance specifications (MNPS) airspace in accordance with regional supplementary procedures, where minimum navigation performance specifications are established, if the operator has been granted an approval by the competent authority to conduct such operations.
DOCUMENTATION
MNPS and the procedures governing their application are published in the Regional Supplementary Procedures, ICAO Doc 7030, as well as in national AIPs.
SPA.MNPS.105 MNPS operational approval
Regulation (EU) No 965/2012
To obtain an MNPS operational approval from the competent authority, the operator shall provide evidence that:
(a) the navigation equipment meets the required performance;
(b) navigation displays, indicators and controls are visible and operable by either pilot seated at his/her duty station;
(c) a training programme for the flight crew members involved in these operations has been established;
(d) operating procedures have been established specifying:
(1) the equipment to be carried, including its operating limitations and appropriate entries in the MEL;
(2) flight crew composition and experience requirements;
(3) normal procedures;
(4) contingency procedures including those specified by the authority responsible for the airspace concerned;
(5) monitoring and incident reporting.
LONG RANGE NAVIGATION SYSTEM (LRNS)
(a) For unrestricted operation in MNPS airspace an aircraft should be equipped with two independent LRNSs.
(b) An LRNS may be one of the following:
(1) one inertial navigation system (INS);
(2) one global navigation satellite system (GNSS); or
(3) one navigation system using the inputs from one or more inertial reference system (IRS) or any other sensor system complying with the MNPS requirement.
(c) In case of the GNSS is used as a stand-alone system for LRNS, an integrity check should be carried out.
(d) For operation in MNPS airspace along notified special routes the aeroplane should be equipped with one LRNS.
