Study Notes
Navigation Systems
- RNP (Required Navigation Performance) allows an aircraft to fly a specific path between two 3D-defined points in space.
- RNAV (Area Navigation) and RNP systems differ in that RNP has a more stringent accuracy requirement, typically used for Instrument Approach Procedures.
RNP Specifications
- An RNP specification is a set of criteria defining the required navigation performance for a specific procedure or airspace.
RNP vs. RNAV
- Use RNP instead of RNAV when a more precise navigation capability is required, such as in Instrument Approach Procedures.
RNP Values
- An RNP of 10 means the aircraft must be able to maintain its position within 10 nautical miles of the desired path.
Electronic Charts
- International Hydrographic Organization (IHO) sets the standards for electronic charts.
Electronic Chart Display and Information System (ECDIS)
- The primary purpose of ECDIS is to provide a safe and efficient navigation system for mariners.
- ECDIS is an electronic navigation system that integrates Electronic Navigational Charts (ENCs) and other navigation data.
Electronic Navigational Charts (ENCs)
- ENCs can be used by all vessels to meet the performance standard for ECDIS.
Regional Electronic Navigational Chart Centres (RENCs)
- RENCs are responsible for collecting, processing, and distributing ENCs to ensure their accuracy and consistency.
Inland Electronic Chart Display and Information Systems
- Inland Electronic Chart Display and Information Systems are used for navigation on inland waterways, such as rivers and lakes.
