Aeronautical Fixed Service (AFS)

This is the main communication network used for ground-to-ground communication in aviation. It includes all the systems used to send messages like flight plans, NOTAMs, and weather data between airports, air traffic control, and other aviation offices.

Aeronautical Fixed Telecommunication Network (AFTN)

The old system within the AFS. Used for many years to send plain-text messages. Think of it like a global fax or telex system for aviation.

ATS Message Handling System (AMHS)

The new system that is replacing AFTN within the AFS. Works like modern email.

SWIM

AFTN is replaced by AMHS, and in the future AMHS will be replaced by?

1. Check if connection problem -> ping server/gateway

2. Check if multiple retrieval requests are made by ATC -> close retrieval requests tabs

3. Clear alarms (press F11 2x to open alarms tab)

4. Close, then re-login CADAS Center terminal

5. *Note: Ask senior ANS member/ supervisor of the facility for their facility procedure

Troubles at Remote

CADAS hanging

1. Check if connection problem -> ping server/gateway o If unable to ping server, check VSAT (remote VSAT/VSAT Hub/Server down) o If unable to ping gateway, check LAN cable (blinking/loose/defective)

2. Check firewall

3. Check IP settings (static IP Address gateway)

4. *Note: Ask senior ANS member/ supervisor of the facility for their facility procedure

Troubles at Remote CADAS

no connection

1. For remote sites with GEO1 and GEO2 VSAT links and when current GEO link is unserviceable, it is possible to use the other link

2. *Note: ANS remote facilities should already have a copy of procedures.
