The commercial flight deck has come far from the early days of widespread air travel. In the past few decades, as the steam gauges, analog switches, and electrical fuses of old gave way to digital autopilots, glass computer displays, and detailed systems monitoring, the number of required crew in the cockpit dropped from an original five to just two, the classic pilot-copilot duo.

However, with new data display methods and tools, artificial intelligence automation, and safer aircraft and systems than ever before, the above question is once again at the center of discussions over Single-Pilot Operations (SPO). AI has already proven itself at flying widebody airliners; as computers once again threaten human control in the flight deck, fierce debate has ignited over the practicality, safety, and reception of a single-pilot future.
