AOPA wrote a letter to the FAA last week saying that if a new policy outlined in Advisory Circular (AC) 90-100A is allowed to remain as it is currently written, more than 25,000 GPS users will not be able to use the unit as a substitute for DME or Rnav procedures.
To help business aircraft operators cope with new Rnav routes and procedures as of September 1, the FAA is developing a Web-based RAIM (receiver autonomous integrity monitor) prediction service that will be made available for general use by flight crews, according to NBAA.
At the FAA’s two-day New Technology Workshop last month, the focus was sharply on the Next Generation Air Transportation System (NGATS). The key enablers to get there, according to Nick Sabatini, FAA associate administrator for aviation safety, will be “performance-based” navigation and Internet-like access to critical information such as near real-time weather.
Dramatic reductions in approach minimums at terrain-challenged airports are among the more spectacular results of applying RNP-Rnav. But more widespread benefits are promised when procedures based on the capabilities of modern aircraft supersede those that tie the airplanes to expensive ground navigational aids.
Owners of older Honeywell GNS-X flight management systems have until the end of the month to take advantage of special pricing on new GNS-XLS units, the maker announced here yesterday. Buyers who take advantage of the promotional offer will receive a $3,000 discount off the price of a new GNS-XLS FMS, as well as free software that introduces the latest worldwide navigation capabilities to the unit, according to the company.
Operators using the new Rnav SID procedures at Dallas/Fort Worth and Hartsfield-Jackson Atlanta International Airports can expect a visit from their principal operations inspectors (POIs). The FAA said implementation has been a “general success,” with benefits such as greater efficiency and reduced communications.
To help business aircraft operators cope with new Rnav routes and procedures that took effect last month, the FAA is developing a Web-based RAIM (receiver autonomous integrity monitor) prediction service that will be made available for general use by flight crews, according to NBAA.
The FAA has implemented performance- based navigation in the form of standard instrument departures (SIDs), en route Q and T routes, standard arrival routes (Stars) and RNP special and Rnav approaches.
Eurocontrol provided a short guide to RNP and Rnav concepts and terminology as a primer for delegates.
Performance-based navigation was identified in ICAO’s Future Air Navigation System concept of the early 1990s, which defined required navigation performance capability as a parameter “describing lateral deviations from assigned or selected track as well as along-track position-fixing accuracy on the basis of an appropriate containment level.”
