~ Regulation SPA - ANNEX V - Specific Approval Operations Centrik

(a) The operator approved to conduct RNP AR APCH operations, should have an RNP
monitoring programme to ensure continued compliance with applicable rules and to
identify any negative trends in performance.
(b) During an interim approval period, which should be at least 90 days, the operator should
at least submit the following information every 30 days to the competent authority.
(1) Total number of RNP AR APCH operations conducted;
(2) Number of approach operations by aircraft/system which were completed as
planned without any navigation or guidance system anomalies;
(3) Reasons for unsatisfactory approaches, such as:
(i) UNABLE REQ NAV PERF, NAV ACCUR DOWNGRAD, or other RNP
messages during approaches;
(ii) excessive lateral or vertical deviation;
(iii) TAWS warning;
(iv) autopilot system disconnect;
(v) navigation data errors; or
(vi) flight crew reports of any anomaly;
(4) Flight crew comments.
(c) Thereafter, the operator should continue to collect and periodically review this data to
identify potential safety concerns, and maintain summaries of this data.

SUBPART C OPERATIONS WITH SPECIFIED MINIMUM NAVIGATION PERFORMANCE (MNPS)
Reference Description
SPA.MNPS.100 MNPS operations
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 CAA
to conduct such operations.
SPA.MNPS.100 GM1 MNPS 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
To obtain an MNPS operational approval from the CAA, 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.
SPA.MNPS.105 AMC1 MNPS operational approval
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.
SUBPART D OPERATIONS IN AIRSPACE WITH REDUCED VERTICAL SEPARATION MINIMA (RVSM)
Reference Description
SPA.RVSM.100 RVSM operations
Aircraft shall only be operated in designated airspace where a reduced vertical separation minimum
of 300 m (1000 ft) applies between flight level (FL) 290 and FL 410, inclusive, if the operator has been
granted an approval by the CAA to conduct such operations.
SPA.RVSM.105 RVSM operational approval
To obtain an RVSM operational approval from the CAA, the operator shall provide evidence that:
