Anyone else think this is a good idea?
I think it is a great idea and I was looking for the same thing when I was training for my instrument rating. Listening to a series of clearances gives you the opportunity to practice writing them down. In fact, there is a CD-based audio program that offers just this but cost money. Why spend for that, though? Instead, a clip of nothing but clearances could be offered here.
I travel a lot for my job, but I do have dead time at night during weekday evenings. If no one else steps forward, I will volunteer to do so but it won't be until early next week. My first recommendation in compiling a list of clearances that would benefit a new instrument student would be to go to one of the many "general aviation" airport archives, rather than the large, class B airport clearance delivery archives. There are several reasons why, including the difference in speed of the controller's delivery and the difference in route types (jetways versus victor airways, etc).
