Question: 1 / 400

What does the acronym RAIM stand for in GPS navigation?

Receiver Autonomous Interference Management

Receiver Autonomous Integrity Monitoring

The acronym RAIM stands for Receiver Autonomous Integrity Monitoring. This is a critical function in aviation GPS systems that ensures the integrity and reliability of the GPS information provided to pilots. RAIM works by using multiple GPS satellites to verify that the position data it receives is accurate and trustworthy. If the system detects discrepancies in the signals, it can alert the user about potential errors, thereby reducing the risk of navigation inaccuracies.

This capability is essential for instrument approaches and other precise navigation tasks, as it helps to ensure that the aircraft is relying on accurate data while flying in challenging conditions. Without RAIM, GPS navigation could not be trusted as much, especially in instrument flight rules (IFR) operations where reliance on accurate position data is paramount. The other options do not accurately describe the functionality provided by RAIM.
