The is related to the other thread on winch launch. I am a firm believer in
not accepting an aerotow rope or a winch cable until the pilot is completely
ready to fly. I teach my students the same.

As a learning routine, I will brief the line person to interrupt the student
pilot while he is doing the pre-flight checklist and agressively insist the
pilot accept the rope RIGHT NOW. If the student asserts his Pilot in
Command authority and tells the line person to back off until asked for the
rope, the student passes the test.
