RAIM Prediction Websites
To enable pilots to quickly determine whether enroute and/or approach level RAIM will be available, the FAA and EUROCONTROL have created "dispatch level" websites that predict RAIM status to meet pre-flight check requirements.
- The FAA's RAIM prediction website "AC 90–100" covers US territories in graphical map format (showing green for RAIM available and red for RAIM not available) and is located at http://www.raimprediction.net/ac90-100/
- EUROCONTROL provides international coverage for most waypoints in the worldwide aviation waypoint database and displays results in a "timeline" bar showing predictions of whether baro-aided or non-baro-aided RAIM will be available. The EUROCONTROL "AUGUR" website is located at http://augur.ecacnav.com/augur/app/home
- EUROCONTROL puts a disclaimer on its data (stating that USCG data takes precedence), whereas the FAA certifies its website as meeting regulatory requirements.
- As of 1st July 2012 AUGUR coverage has been limited to ECAC airspace only.
- The GNSS RAIM/RNP Prediction Service, hosted by DW International, offers worldwide coverage for all PBN applications including RNP 10, RNAV 5, RNAV 2, RNAV 1, RNP 4, Basic RNP-1, RNP Approach and RNP AR Approach down to 0.1NM. The online tool is an alternative to the automated service integrated directly into flight planning software. It is intended to keep updated in line with new editions of the PBN Manual and any worldwide specific regulation.

Famous quotes containing the word prediction:
“Recent studies that have investigated maternal satisfaction have found this to be a better prediction of mother-child interaction than work status alone. More important for the overall quality of interaction with their children than simply whether the mother works or not, these studies suggest, is how satisfied the mother is with her role as worker or homemaker. Satisfied women are consistently more warm, involved, playful, stimulating and effective with their children than unsatisfied women.”
—Alison Clarke-Stewart (20th century)
