Different fields in aircraft :
  • Aerodynamics - Is the study of the motion of air over an object.
  • Propulsion - Is the study of engine and its motions.
  • Thermodynamics - Study of the effects of work, heat and energy on a system.
  • Aircraft Structures - Study of design and construction of airframe parts. 
  • Flight Dynamics - Study of the performance, stability, and control of flight in air.
  • Avionics - Study of electronics used in aircraft.
Major parts of an aircraft :
  • Fuselage.
  • Landing Gear.
  • Flight control surfaces.
  • Wings.
  • Stabilizers.
  • Aircraft Engines.
Basic instruments to control and monitor the aircraft :
  • Altimeter - Indicates the height of the aircraft above the sea level.
  • Attitude indicator or Artificial horizon - Indicates the orientation of aircraft about its pitch and roll axis.
  • Airspeed indicator - Indicates the aircraft speed relative to the surrounding air.
  • Magnetic compass - Indicates the aircraft heading relative to the magnetic north.
  • Vertical speed indicator or Variometer - Indicates the rate of climb or descent of the flight.
  • Turn and balance indicator - Indicates the direction of the turn and rate of turn of the flight.
Major forces acting on an aircraft :
  • Thrust.
  • Drag.
  • Lift.
  • Gravity or weight.

Flight control surfaces :
Control surfaces which helps pilot to control and stabilize the aircraft in a defined direction. There are two types of control surfaces they are primary and secondary control surfaces.

Primary control surfaces :
Rudder ( to control the flight along the yaw axis).
Aileron ( to control the flight along the lateral axis ).
Elevator ( to control the flight along the longitudinal axis).

Secondary control surfaces :
