Receiver Autonomous Integrity Monitoring (RAIM ) assesses the integrity of the Global Positioning System (GPS) signals. This system predicts outages  for a specified geographical area.  These predictions are  based on the location, path, and scheduled GPS satellite outages. You can use RAIM to predict outages for a planned route or specific airport.

·   To perform a RAIM prediction for a specific aircraft, select an aircraft in the Select Tail list and perform step 1 to step 8 in the RAIM prediction for selected airports.

·   When performing the RAIM prediction for a specific aircraft,  the data in the Receiver Type, Barometric Aiding and Integrity Level fields are are auto-populated from the Aircraft Profile.

·   When performing the RAIM prediction for a specific aircraft, if the profile of the aircraft is not available, then message Aircraft Profile not found. Click here to create profile appears at the top of the page. To create an aircraft's profile, click Click here to create profile

·   When performing the RAIM prediction for a specific aircraft, if the profile of the tail is available and the GPS receiver informations is not available, the message Tail not setup for GPS navigation. Click here to setup appears at the top of the page. To set a tail for GPS navigation, clickClick here to setup.

·   Clicking the Calculate RAIM for Flight Plan displays the Review Flight Plans page. You can perform the RAIM prediction for any of the displayed flight plans. The prediction is performed based on the aircraft profile and route flown. The predictions are for a duration of +/- 60 minutes of the ETD at 15 min intervals with a sampling period of one minute.
