The reference material for TAF3 is ENR 1.1-73.
Basically if the AD has a TAF3 the first 3 hours of the TAF are treated differently. Any PROB forecast of visibility reductions below the alternate minimima or the PROB presence of TS doesnt require holding or ALT fuel ( however there normal presence absent of any PROB still requires alternate/holding). Additionally the 30 min buffers for FM BCMG are not applicable. So if there is a FM02z of bad weather and your ETA is 0159z, you legally dont require holding/alternate ( if you are still in the first 3 hours of the TAF3 validity)
ok great. And the last thing confusing me is from p121 MOS section 4.05. It says the estimated time of use of a destination is eta +\- 30 mins. So back to my original example, my eta is 1200, then the time of use is 1130-1230. So then I think a FM at 1245 would apply, it would have to be 1301 to not apply?
Thoughts?
