RETURNING PILOTS
A few minutes per change.
Each refresher takes one change from what's changed, explains what it means in the cockpit, quotes the rule word for word, then hands you the practice questions that test it.
Airspace
Not every change has a refresher yet.
A refresher needs the changed rule in a source we can quote word for word. Where we only have a link, the timeline still lists the change and where to read it.
