Thanks guys. It seems the general consensus here and on Wannabes is that spin axis and the sensitive axis are not 2 terms for the same thing. Therefore the quote from my notes above would be correct. It makes sense that the 'sensitive' axis is the axis around which the gyro is sensitive, not the one around which it spins. However, there was a line in my notes in the section about basic gyroscopic principles which stated that they were the same thing. This caused the initial confusion which led to the above stated quote being taken in the wrong context. The offending line has been now crossed out in my notes, and the error pointed out to my ground instructor,
