Design Recommendations for Extraneous Oxygen Mask Valve to Reduce Pilot Respiratory Effort in High Performance Aircraft

1. Pilots reporting sensation of "sucking rubber" both on ground and in-flight 2. Increased breathing resistance during inhalation may be due to inadequate supply 3. Previous Aircrew Flight Equipment (AFE) incorporated an Anti-Suffocation Valve (ASV) in the event of pilot incapacitation.
