A good idea to use powerpoint for the more complex ground briefs. I certainly find them very useful as they are:
a. easy to understand so long as you don't make them too complicated.
b. look professional and create the right impression to the student. Don't 'gash it' with poorly constructed models and fag packet briefings, you will quickly lose the respect of your student.
c. are easy to store (hard drive or floppy) and easy to update.
I recommend them to you, but use other aids as well to get the whole message across.
remember....RCP
Happy instructing!
