You're right, thats such a good idea! Everyone else in this thread is sooo dumb for not having though of it... So, you're suggesting every time the instructor needs to tell the deaf student something about the plane, he pulls out a pen and paper, rights it down, then hands it to the student who has to take his hands off the transmitter and eyes of the plane to read it all while the trainer plane is in the air?

Did you even read the original post, or just the thread title? This thread isn't about communicating with deaf people in general, its about communicating with deaf people while teaching them to fly using a buddy-box. Especially considering that speaking is the primary form of communication between a student and his instructor while having flight lessons on a buddy box.

No one here thinks deaf people are dumb, but they DO have a "special need" when it comes to flight training, and Brad and his club have found a good solution, thats all. Chill.
