Flight instruction is inherently different in two respects...
-Except for a student's very first flight or two, the student has some knowledge of the instructor and his skills and attitudes.
-On almost all instructional flights, the student will be able to determine if the instructor is not flying in a safe manner.
Basically, students are not as helpless or as ignorant as the public, so they don't need the same protections.
