  1. Thrust Reversers

  2. Inadvertent Reverser Stowage • Captain decided to reject the takeoff • Reversers deployed • Damage from tire debris resulted in reverser stowage • Captain did not initially recognize reverser stowage

  3. Thrust Reverser Cues • Minimal visual cues, no aural cues • Engines producing forward thrust

  4. TR DEPLOY Thrust Reverser Cues • Three small annunciator lights located on each pilot’s side of forward glareshield • TR DEPLOY light extinguished immediately

  5. TR ARM Thrust Reverser Cues • Three small annunciator lights located on each pilot’s side of forward glareshield • TR DEPLOY light extinguished immediately • TR UNLOCK light on during transit TR UNLOCK

  6. TR ARM Thrust Reverser Cues • Three small annunciator lights located on each pilot’s side of forward glareshield • TR DEPLOY light extinguished immediately • TR UNLOCK light on during transit • TR ARM light flashed momentarily then extinguished TR UNLOCK

  7. Thrust Reverser Cues • Critical decision based on lack of lights • 70 similar lights located in area • Reverse thrust lever position did not match thrust condition • Lack of lever movement • No tactile cue of emergency condition

  8. Thrust Reverser Cues • Reverse lever back but commanding forward thrust • Counterintuitive action required during a rejected takeoff

  9. Training: Inadvertent Stowage • Pilots normally trained in landing scenario • Inadvertent reverser stowage rarely demonstrated during takeoff scenario
