EFAS, FSS, AFSS

Asked by: 3779 views , ,
FAA Regulations, Weather

Hi guys!!

I'm studying AIM now and I can't distinguish EFAS, FSS, AFSS.

I know EFAS was flight watch, and AFSS is automated FSS, but that's it.

I think All three are same. Could you let me know which facilities are which?

thanks

    You’ll want to look at an updated version of the AIM. EFAS (Flight Watch) was phased out and all its unique functions were absorbed into what the FSS does. Here’s the FAA order explaining it: https://www.faa.gov/documentLibrary/media/Notice/N_JO_7110.702_2-6-2_and_2-9-3_EFAS_Realigned_to_Inflight_Position.pdf
