Tonight, (January 13 2021) at 0506z, I clicked on the ARINC Atlantic HF Assignments webpage at: Atlantic HF Assignments.
The HF frequency assignments listed were to be used January 12,2021 2000z to 0400z.
That means they expired at 0400 January 12, 2021. 25 hours before I clicked on the webpage.
The Atlantic HF frequency assignments had not been updated for over 25 hours.
Although this is the longest NO UPDATE period I have seen,
I have often been noticed that the HF assignments are not being updated until several hours after their expiration.
I have NOT noticed this on the Pacific HF Assignments page at;: Pacific HF Assignments
Is this normal?
Or is it just not important anymore in the age of SatVoice, InMarSat, ACARS and other data transmissions?
