RAIM comes available as part of our skybook aviation software. Providing our aviation customers with integrated RAIM Prediction Mapping into their flight planning systems and RAIM reports accessed on their EFB and in briefing packs.

But what is RAIM, and how does RAIM work in Aviation?

What is the purpose of RAIM?

Receiver Autonomous Integrity Monitoring (RAIM) is a technique used in aviation to monitor the integrity of GNSS signals.

It ensures that the navigation solution provided by the receiver meets the required performance standards for safety-critical applications.

RAIM is particularly important in aircraft navigation to detect and mitigate errors in satellite signals, providing a reliable means of ensuring the accuracy and integrity of position information.

RAIM accesses a broad constellation of satellites across the globe to detect and then exclude faulty signals that could show inaccurate positioning. The position is then recalculated, minus the faulty signals, resulting in a far more accurate position being plotted.

How does RAIM improve aviation safety?

By performing consistency checks on these signals, RAIM can alert users if there are anomalies or discrepancies present that could compromise the accuracy of their position solution.

This capability enhances safety by enabling pilots to rely on trustworthy navigation information even in challenging environments or when faced with potential signal interference.

RAIM plays a crucial role in maintaining situational awareness and supporting precise positioning during critical flight phases, contributing significantly to overall aviation safety.

How does RAIM enhance skybook?

skybook utilises an integration with NavBlue’s RAIM+, to create RAIM reports for the airports and airport types defined within skybooks settings.

It integrates seamlessly within our dispatch and EFB software, further enhancing the accuracy of route plotting, charts, weather, ETOPS information and much more.

RAIM reports are generated automatically as part of a briefing pack, using the operational criteria set during initial system configuration. This ensures that all data appearing within a briefing is accurate and based on the stringent operational needs of each client.

Examples of a RAIM report

See the images below of how our RAIM reports are displayed...

RAIM report on Flight Dispatch system:

RAIM report on PDF briefing pack:

skybook provides RAIM reports for airports along the flight route and is configured to interact with NavBlue to produce the report required by the airline.

Individual RAIM profiles can be created which can then be assigned to specific airfields, such as 'LFPO' or to airfield types, ‘Arrival Alt’, ‘Drift Down’ etc. These profiles hold parameters that are understood by the NavBlue RAIM integration. 

RAIM on the EFB

Within the skybook EFB, RAIM reports are easily accessed by viewing the airfields within the digital briefing section. If an Airfield has a RAIM service, then a satellite icon will display next to it.

This provides a more efficient way for pilots to quickly see where any potential RAIM outages are along the route, without having to scroll through lots pages or documents.
