A good, basic supplement to go with Ground Operation and Servicing section for general aircraft maintenance classroom work. I don't remember if my class lectures covered what to do if you don't understand a hand signal but the emphasis this King's course places on it being ok to stop and signal that you don't know is helpful and seeing hand signals in action is more memorable and understandable than pictures in a book or on a slide show. After watching this course I feel better about what to do if I get nervous and forget something for my upcoming class assignment.
