What navigation specification is typically used in oceanic operations?
RNAV 10
T-routes and Q-routes are examples of this Nav Spec. Aircraft must maintain a total system error of not more than 2 NM for 95 percent of the total flight time. RNAV 10. Typically RNAV 10 is used in oceanic operations.
Description. PBN aims to ensure global standardisation of RNAV and RNP specifications and to limit the proliferation of navigation specifications in use world-wide. It is a new concept based on the use of Area Navigation (RNAV) systems.
How does performance based navigation work?
Performance-based Navigation (PBN), in simple terms, redefines the aircraft’s required navigation capability from sensor (equipment) based to performance based. For each specification, there is a lateral containment value that the aircraft must be able to remain within, in order to be approved for that operation.
How are leg types defined in RNAV procedure?
RNAV Leg Types. A leg type describes the desired path proceeding, following, or between waypoints on an RNAV procedure. Leg types are identified by a two-letter code that describes the path (e.g., heading, course, track, etc.) and the termination point (e.g., the path terminates at an altitude, distance, fix, etc.).
How are leg types identified in an aircraft?
Leg types are identified by a two-letter code that describes the path (e.g., heading, course, track, etc.) and the termination point (e.g., the path terminates at an altitude, distance, fix, etc.). Leg types used for procedure design are included in the aircraft navigation database, but not normally provided on the procedure chart.
A series of leg types are coded into a navigation database to make a light procedure. The navigation database allows an FMS or GPS navigator to create a continuous display of navigational data, thus enabling an aircraft to be lown along a speciic route. Vertical navigation can also be coded.
What do you need to know about Nav specs?
Nav Specs are a set of aircraft and aircrew requirements needed to support a navigation application within a defined airspace concept.
