Protective Equipment

• Protective Clothing and Equipment
• Oxygen was first supplied by an oxygen mask then
  by a pressure suit.
• The pressure suit is the basis for space suits.
• The pressure suit and G-suit were developed to
  protect military pilots in high-performance
  aircraft.

Protective Equipment

• Protective Clothing and Equipment
• Three types of oxygen breathing systems.
• Continuous-flow
• Diluter-demand
• Pressure-demand
• Oxygen masks are used above 10,000 feet in
  unpressurized Air Force aircraft.

Protective Equipment

• Pressurized Cabins
• The first American-built pressurized cabin was
  developed in 1937 with the XC-35.
• The difference in pressure between the atmosphere
  in the cabin and that on the outside is called
  the pressure differential.
• Most military aircraft have less pressure in
  their cabins to reduce weight and allow more
  maneuverability.

Protective Equipment

• Pressurized Cabins
• The cabin must have excessive water vapor
  removed, be free of contaminants, and be kept at
  a comfortable temperature.

Protective Equipment

• Escape Equipment
• Parachutes
• canopy
• pack
• harness

Protective Equipment

• Escape Equipment
• Ejection-seat system
• Usually equipped with harness, guardrails, a
  footrest, and a headrest

Flight Simulators

• Stress Devices
• Low-pressure chamber
• Trainees take simulated flights after physiology
  training and before actual high-altitude flights.

14
Flight Simulators

• Barany Chair
• A rotating chair with a large bearing system to
  ensure smooth operation.
• Allows trainee to both experience and witness the
  effects of spatial disorientation.
• Nystagmus Eye movement
• Graveyard Spin False sensations
• Coriolis Illusion Head tumbling

15
Flight Simulators

• Vista Vertigon
• Induces vestibular illusions
• Creates realistic cockpit situations
• Provides visual scenes and narration
• The vertigon is spun on its axis
• The students manipulate switches on a console

16
Flight Simulators

• Mockups
• Mockups and simulators give the effect of
  conditions of flight.
