ICAO performance-based navigation (PBN) specifies that aircraft required navigation performance (RNP) and area navigation (RNAV) systems performance requirements be defined in terms of accuracy, integrity, availability, continuity, and functionality required for the proposed operations in the context of a particular airspace, when supported by the appropriate navigation infrastructure.
Required Navigation Performance provides a specified level of navigational accuracy for the airspace or stage of flight an aircraft is operating in. Required navigation performance (RNP) is a type of performance-based navigation (PBN) that allows an aircraft to fly a specific path between two 3D-defined points in space.
Localizer performance with vertical guidance (LPV) are the highest precision GPS (SBAS enabled) aviation instrument approach procedures currently available without specialized aircrew training requirements, such as required navigation performance (RNP).
A simple diagram showing the main difference between traditional navigation and RNAV methods. Area navigation (RNAV, usually pronounced as / ˈ ɑːr n æ v /) is a method of instrument flight rules (IFR) navigation that allows aircraft to fly along a desired flight path, rather than being restricted to routes defined by ground-based navigation beacons.
The basic principles of air navigation are identical to general navigation, which includes the process of planning, recording, and controlling the movement of a craft from one place to another. [ 1 ] Successful air navigation involves piloting an aircraft from place to place without getting lost, not breaking the laws applying to aircraft, or ...
A navigational aid (NAVAID), also known as aid to navigation (ATON), is any sort of signal, markers or guidance equipment which aids the traveler in navigation, usually nautical or aviation travel. Common types of such aids include lighthouses , buoys , fog signals , and day beacons .
In addition, marine navigation software often has option to control external autopilot for automated boat navigation. It may incorporate GRIB weather overlay on the chart, Tide predictions and other related information services of additional use to mariners. Free and open source. OpenCPN (Cross-platform) open source and free
Other navigation information can be used to determine at which intersection the receiver is located. Hyperbolic navigation is a class of radio navigation systems in which a navigation receiver instrument is used to determine location based on the difference in timing of radio waves received from radio navigation beacon transmitters.
