possession of the appropriate MNPS and RVSM Approvals issued by the State of Registry
of the aircraft or by the State of the Operator.
1.1 GENERAL
1.1.1 It is implicit in the concept of MNPS that all flights within the airspace achieve the highest
standards of horizontal and vertical navigation performance and accuracy. Formal monitoring programmes
are undertaken to quantify the achieved performances and to compare them with standards required to ensure
that established Target Levels of Safety (TLS) are met.
Note : Collision Risk Modelling is used to estimate risk in each of the three dimensions (i.e.
lateral, longitudinal and vertical). Target maxima set for these estimates are expressed in terms of
potential collisions per flight hour and are known as “Target Levels of Safety(TLSs)”.
1.1.2 Aircraft operating within MNPS Airspace are required to meet Minimum Navigation
Performance Specifications (MNPS) in the horizontal plane through the mandatory carriage and proper use
of a specified level of navigation equipment that has been approved by the State of Registry or State of the
Operator for the purpose. Such approvals encompass all aspects affecting the expected navigation
performance of the aircraft, including the designation of appropriate cockpit/flight deck operating
procedures. The requirements are set out in ICAO NAT Doc 001, „Consolidated Guidance and Information
Material concerning Air Navigation in the North Atlantic Region‟ (available at http://www.paris.icao.int/ ).
1.1.3 With the final phase implementation of RVSM at all levels in NAT MNPS Airspace
(January 2002), all aircraft intending to operate within NAT MNPS Airspace must be equipped with
altimetry and height-keeping systems which meet RVSM Minimum Aircraft System Performance
Specifications (MASPS). RVSM MASPS are contained in ICAO Doc 9574 and detailed in designated FAA
document, 91-RVSM, and in Joint Aviation Authority (JAA) Temporary Guidance Leaflet (TGL No.6),
Revision 1. These documents can be downloaded from:
http://www.faa.gov/about/office_org/headquarters_offices/ato/service_units/enroute/rvsm/documentation
and http://www.ecacnav.com/downloads/TGL6rev1.pdf, respectively.
1.1.4 NAT Doc 001 (available at http://www.paris.icao.int/ ) is maintained by the ICAO European
and North Atlantic Office (Paris) and is provided, together with the RVSM MASPS documents, to assist
States of Registry, operators, owners and planning staff who are responsible for issuing or obtaining
MNPS/RVSM approvals for aircraft. However, the ultimate responsibility for checking that a NAT
MNPS/RVSM flight has the necessary approval(s) rests with the pilot in command. In the case of most
regular scheduled flights this check is a matter of simple routine but pilots of special charter flights, private
flights, ferry and delivery flights are advised to pay particular attention to this matter. Routine monitoring of
NAT traffic regularly reveals examples of pilots of non-approved flights, from within these user groups,
flight planning or requesting clearance within MNPS Airspace. All such instances are prejudicial to safety
and are referred to relevant State Authorities for further action.
1.1.5 While not a specific element of NAT MNPS approval, pilots and operators are reminded that
for flights over the NAT, ICAO SARPS Annex 6, Part 1, Chapter 6, requires carriage of Emergency Locator
Transmitters (ELTs). It should be further noted that new specifications for these beacons to operate

exclusively on frequency 406 MHz (but with a 121.5 MHz search and rescue homing capability) have been
in effect since January 2005. New aircraft have been required to be so equipped since 2005.
1.2 APPROVAL
1.2.1 Approval for MNPS operations will require the checking by the State of Registry or State of
the Operator, of various aspects affecting navigation performance. These aspects include: the navigation
equipment used, together with its installation and maintenance procedures; plus the crew navigation
procedures employed and the crew training requirements.
1.2.2 Since MNPS Airspace is now designated as RVSM airspace at all levels (i.e. FL290-410
inclusive) State RVSM Approval is also required to operate within MNPS Airspace. RVSM Approvals
prescribe both airworthiness requirements, to ensure aircraft height-keeping performance in accordance with
the RVSM MASPS, and also crew operating procedures. In general RVSM Approvals granted by most
States are not regionally specific but are valid for world-wide operations. However, some crew operating
procedures, particularly those to be followed in contingency situations, are specific to the airspace
environment. Such procedures for use in MNPS airspace vary from those adopted in a domestic airspace
