This would only work if the Ab Inits had operated out of the same airfield that you are familiar with.
Our Instructor gave the following example after drawing a RWY 36/18 on the board.
You take off from RWY 18 climb straight ahead in nil wind at 100kts climbing to 1000' then turn left hdg 080 climb another 1000'.........
He basically radar vectors us all over the place with climbs and descents due to weather, ATC or traffic etc. at certain times he then gets us to show him on the board where and what altitude we were at, he continues this to a landing at another airfield near where we took off.
After the whole class predicts where we landed, he points out we are all dead because turning left onto 080 and climbing to 2000' smacks you right into a ridge that climbs to around 2600'.
Now we were all new to flying, we knew about the terrain but had only flown west to the training area at that time at 2000'
The exercise had me thinking of time and space but we all forgot about terrain and how familiarity can make things seem fine.
This might be a good way to get your point across, with some good class participation rather than just talking, if not it'll blow 20mins.
