It's money well spent to hire a professional for troubleshooting advanced inflight high speed data system failures.
When a high-speed data (HSD) failure is in an ancillary system, such as Sat AFIS or ACARS, I genuinely recommend hiring a professional to assist you. It will be money well spent. However, if you are determined to proceed on your own, do two things:
- Determine if the satellite terminal is passing the AFIS traffic to the ground network. Your service provider should be able to assist with this.
- Ensure that your satcom service provider routed your request to the proper location at the datalink provider’s end.
Unfortunately, there is often a fair amount of blame that occurs between satcom and datalink service providers. In many cases they are companies with competing services. To reduce confusion and root out the error relatively quickly, get both parties on a conference call. In most cases, AFIS / ACARS problems are often resolved at the datalink provider’s end.
These systems are very complex. I cannot stress enough the importance of getting advanced troubleshooters involved early.
