34.44 Information Processing

34.44.2 Identify the human sensors pilots depend on for information acquisition.

Pilots receive information through several human sensory systems.

(a) Vision

Vision is the pilot's primary source of information. The eyes provide information about:

  • aircraft attitude and position;

  • terrain and obstacles;

  • other aircraft;

  • weather; and

  • instruments and displays.

 

(b) Hearing

Hearing provides information from:

  • radio communications;

  • warning signals;

  • engine and aircraft noises; and

  • changes in normal sounds that may indicate a problem.

 

(c) Touch

Touch receptors in the skin allow the pilot to sense:

  • pressure;

  • temperature;

  • vibration; and

  • contact with aircraft controls.

 

(d) Proprioception

Proprioceptors are located mainly in the muscles, tendons and joints.

They provide information about the position and movement of the body and limbs, including muscle tension and joint position.
