  1. 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).

  2. 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.

  3. 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.

  4. 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.
