ICAO 9613 Flashcards
PBN
ICAO 9613
IS 91-001
Area navigation based on performance requirements for aircraft operating along an ATS route, on an instrument approach procedure or in a designated airspace.
Permits reduction in fuel consumption and better airspace utilization.
RNAV today is an application of PBN, it utilizes a combination of sensors to meet performance specifications. INS/VOR/DME/GNSS etc.
All RNAV procedures require ATC to have radar to provide the monitoring and alerting that RNP automatically provides.
RNP includes a monitoring and alerting system when an aircraft deviates from its performance specifications.
performance requirements specifications are expressed in terms of accuracy, integrity, continuity, availability and functionality
RNP AR generic: permits pilots to perform any generic RNP AR
RNP AR specific: applies to a specific approach at a specific airport
SBAS ABAS RAIM
ICAO 9613
Satellite-based augmentation system (SBAS). A wide coverage augmentation system in which the user receives augmentation information from a satellite-based transmitter.
Aircraft-based augmentation system (ABAS). An augmentation system that augments and/or integrates the information obtained from the other GNSS elements with information available on board the aircraft. Note. — The most common form of ABAS is receiver autonomous integrity monitoring (RAIM).
Receiver autonomous integrity monitoring (RAIM). A form of ABAS whereby a GNSS receiver processor determines the integrity of the GNSS navigation signals using only GPS signals or GPS signals augmented with altitude (baroaiding). This determination is achieved by a consistency check among redundant pseudo-range measurements. At least one additional satellite needs to be available with the correct geometry over and above that needed for the position estimation, for the receiver to perform the RAIM function.
