🔍 Key Concepts

• Inmarsat distress priority handling and how channels are assigned • The role of LES (Land Earth Station) vs NCS (Network Coordination Station) in distress traffic • What happens to working frequencies/channels when a distress call is made

💭 Think About

• Ask yourself: which option describes a function or behavior that does NOT match how Inmarsat actually manages distress traffic? • Think about whether every distress request is always moved to a special ‘distress working frequency,’ or whether distress can be handled on assigned channels with priority. • Consider which entity (NCS or LES) is responsible for monitoring and coordinating distress traffic and what “automatic” behavior really occurs.

✅ Before You Answer

• Check which statements describe guaranteed, automatic actions for every distress request — watch for wording that is too absolute. • Verify whether there is a specific, separate Inmarsat Distress working frequency that all requests are always switched to, or if priority can be handled on standard channels. • Confirm the distinct roles of NCS and LES in monitoring and assigning channels for distress versus routine traffic.
