T-34C AIRCRAFT SYSTEMS FAMILIARIZATION
As student aviators, it is necessary for you to become familiar with the T-34C propeller. You
must also become familiar with the location and operation of various propeller components and
forces to be capable of operating the T-34C propeller safely and effectively. This lesson
demonstrates propeller operation on the ground.
