What are the requirements for operating in MNPS airspace?

There are two navigational requirements for aircraft planning to operate in MNPS Airspace….These MASPS require:

  • two fully serviceable independent primary altitude measurement systems;
  • one automatic altitude-control system; and.
  • one altitude-alerting device.

What is NAT HLA in aviation?

High Level Airspace (HLA) A large portion of the airspace of the North Atlantic Region, between FLs 285 and 420 inclusive, is designated as the NAT High Level Airspace (NAT HLA). Until February 2016, most of this airspace was designated Minimum Navigation Performance Standards (MNPS) airspace.

What RNP is required for NAT HLA?

RNP-4
MNPS first came into being in 1977, and this change is significant in that the requirements for approval to enter the new NAT HLA are updated; you must now have RNP-4 or RNP-10.

What are NAT contingency procedures?

Procedures. The basic concept of the in-flight contingency procedures is for the aircraft in distress to offset from the assigned route by 5nm and to climb or descend to an altitude that differs (by 500′ when below FL410 and 1000′ when above that altitude) from those normally used.

Where is Cpdlc required?

The DLS IR mandates CPDLC (controller pilot data link communication) capability for aircraft operating above FL 285. Aircraft capability is understood as the aircraft being properly equipped and fight crew appropriately trained as agreed with the operator’s Competent Authority.

Do operations in the NAT HLA require specific authorization s )?

[NAT Doc 007, ¶1.2. 1] All flights within the NAT HLA must have the approval of either the State of Registry of the aircraft, or the State of the operator.

How many LRNS are normally required for RNP 10 or RNP 4 navigation in the New York Oceanic west airspace?

two operable long
Filing a flight plan for, and conducting operations under, RNP 10 or RNP 4 navigation specifications require the aircraft to be equipped with two operable long-range navigation systems (LRNS).

What is the ICAO Doc 4444 contingency maneuver?

ICAO Doc 4444, ¶15.2. 1.2] The pilot shall take action as necessary to ensure the safety of the aircraft, and the pilot’s judgment shall determine the sequence of actions to be taken, having regard to the prevailing circumstances. Air traffic control shall render all possible assistance.

What is LRNS in aviation?

Long-range navigation system (LRNS). An electronic navigation unit that is approved for use under instrument flight rules as a primary means of navigation, and has at least one source of navigational input, such as inertial navigation system or global positioning system.

What is difference between RNP and RNAV?

While both RNAV navigation specifications (NavSpecs) and RNP NavSpecs contain specific performance requirements, RNP is RNAV with the added requirement for onboard performance monitoring and alerting (OBPMA). RNP is also a statement of navigation performance necessary for operation within a defined airspace.
