Lesson 01 · 5 min · Free preview
Do You Need a Weather Alternate?
Decide from a TAF and destination alternate minima whether weather alone forces a destination alternate (or equivalent holding fuel).
Lesson 02 · 5 min · Members
Navaid & night IFR alternates
Spot when a serviceable aid, lighting or night rules force an alternate even if the weather is fine.
Lesson 03 · 5 min · Members
Fuel IFR
Build a legal IFR fuel case: taxi, trip, variable, reserve, alternate or holding, and the extras examiners hunt.
Lesson 04 · 5 min · Members
TAF3
Use a TAF3 without treating it like a standard TAF — and know when it lets you leave the alternate in the bag.
