Flight Test Textbooks On Line
 

Here's a direct link to a flight testing book in PDF, covering aircraft performance:

Here's another link to one covering stability and control:

These are pretty decent book. But be aware that while it's all about flight test, they are textbooks and have some math in it. Also, they aren't general-purpose aerodynamics texts; they emphasize flight testing.
