In this episode, Matt looks at what GNSS spoofing actually is and how it differs from jamming.

He explores how spoofing can affect much more than just the aircraft's position, and why RAIM does not protect against it.

Matt also discusses some of the practical considerations before, during and after an encounter.

It is highly recommended you read the guidance mentioned in this episode from the FAA, EASA and UK CAA, alongside Airbus and operator procedures.

As always, this podcast is for training and discussion purposes only. Aircraft manufacturer documentation and individual operator procedures take precedence.
