The Chart and the Flight Review
The FAA mandated Flight Review is the perfect opportunity to review, enlighten, and/or enhance, a pilot’s knowledge of airspace and charts. You can use some of the same methods during a flight review as you would with a student during a stage check. A scenario based ground session is a perfect way to explore pilot knowledge.
Get the pilot to talk about his or her normal flying habits. Perhaps they go on regular cross-country trips in various types of airspace. As they tell their story, look for opportunities to quiz them about the chart and applicable Part 91 regulations.
One of the best ways for CFIs to learn is to work with as many pilots as possible. If your student base is small try to provide stage-check services to other CFIs. You can always benefit from this approach and will be a better instructor for it.
