Half an hour to get a drawing on the board? Sounds like your drawings are so elaborate that your artistry may distract your students from your points.
I suggest that if you can't show what you need to with a stick airplane (or in your case, a stick-and-two-circles helicopter), a wind arrow and a couple of dotted lines, that you'd be better off demonstrating it with a model. That way you can show a manoever or a principle, then ask a question and put the model in the student's hand to have them show you the answer. I have seen instructors with demonstration models made variously of cardboard, lego, wire, beer cans, styrofoam and pencils. It can take a bit of practice to hold the model in a way that is most useful to the student. For example it helps if you point the tail towards the student so that left and right are not reversed for them
Other ideas to avoid drawing:
- make the drawing once on a piece of paper, and just show it to the student in the briefing
- bring books containing other people's brilliant diagrams
- make whiteboard templates e.g. a piece of card with a hexagonal cutout produces instant VORs
- have the student draw something first for review, then use their drawing to introduce the next point. e.g. tell the student to make a drawing showing how you would track inbound on a VOR radial, then commandeer their drawing to introduce wind correction.
(Good technique if the student makes wisecracks about your lousy drawings)
Hope that's useful.
