INTRODUCTION

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.
