Both pilots of an A320 fell asleep in the cockpit for 28 minutes

Deadman switches and cockpit alarms

  • Trains use deadman switches because “stop” is generally safe; commenters note there’s no equivalent universally safe action for aircraft.
  • A switch that triggers at the wrong time could cause accidents or distract during real emergencies.
  • Ideas proposed: periodic pilot confirmation (button/timer), alarms that escalate to the cabin, automatic transponder alerts, auto-level with terrain avoidance, automatic descent after depressurization, or enabling remote or auto landing.
  • Others stress alarm discipline: too many or poorly designed alarms are dangerous and cockpit audio is tightly curated.
  • Some argue the existing behavior (autopilot following the flight plan) is already a de facto deadman function in cruise.

Automation and autoland

  • Modern autopilot/autoland can fly and land, but typically require pilot setup, specific conditions, and equipped airports.
  • Garmin’s autoland and some fighter jet safeguards are cited as proof of concept for fully automatic emergency handling.
  • Skepticism remains that such systems can be safely generalized or approved for all airliners any time soon.

Need for human pilots

  • Many see pilots as backup to automation, essential for takeoff, landing, dense traffic, weather, reroutes, and failures.
  • Regulatory conservatism and liability concerns are seen as major barriers to pilotless airliners.
  • Some note that to keep pilots competent as “backup,” they must regularly fly, not just sit idle.
  • There’s strong distrust of fully autonomous commercial aircraft, especially among people familiar with complex software systems.

Pilot fatigue and scheduling

  • Single-pilot napping while the other is awake is reported as common and sometimes formally allowed as “controlled rest.”
  • Both asleep is viewed as a serious breach, though similar incidents have occurred (overshooting destinations).
  • The report that one pilot had newborn twins prompts discussion of parental leave and pro-family policy.
  • Irregular, shifting schedules (example from India) are blamed for chronic fatigue risk.

Human factors and analogies

  • Passive monitoring with automation is described as uniquely fatiguing, compared to active control.
  • Analogies are drawn to “self-driving” cars, ship/yacht autopilot watches, nuclear/physics control rooms, where boredom and vigilance are in tension.
  • Suggestions include AI-based drowsiness detection for pilots, but no consensus on practicality or intrusiveness.
