Autopilot of an aircraft

  1. 1. Autopilot Onboard Aircrafts Seminar for Mechatronics Presented by: Pratheek Manjunath Sathvik Varma 5th semester RVCE, Bangalore
  2. 2. Contents • Introduction • Control surfaces of an Aircraft • Movement of an Aircraft • Principle of Operation • General Architecture of an AP system • Video of Auto land • Bibliography
  3. 3. Introduction • An autopilot is a mechanical, electrical, and hydraulic system used to guide an aeroplane without assistance from the pilot. • The pilot is relieved of most of the physical & mental fatigue of controlling an aircraft and is free to devote his attention to the management and direction of progress of the flight. • On newer aircrafts today, the Autopilot has evolved into a comlex feature encompassing microprocessors and decision making systems which take over the complete control of an aircraft from take-off to landing.
