All systems normal
TAFs
In accordance with proposed changes to ICAO Annex 3, Amendment 74, the
‘validity’ time and ‘change’ time formats have changed to accommodate
migration to TAFs with validity up to 30 hours.
At the same time the practice of issuing ‘Long TAFs’ and ‘Short TAFs’
for the same airport ceased. Each airport will only receive one or the
other.
