How Much Do Pilots Rely on Autopilot?

While science fiction may have given us some ideas about giving complete flight controls to some machine is possible, autopilot is now an old technology, and its use can be seen frequently by those travelling through air. We are not suggesting that it replace human pilots, but it is a system that has proved itself extremely useful. There are multiple scenarios where autopilot is extremely effective in a flight operation. 

Prevent Pilot Fatigue 

Autopilot can fly the fly plane in the desired direction at the desired altitude, and if the weather conditions are optimal and there are no other complications, it can even execute a landing. This helps the pilot not to be fatigued while flying in long-haul flights, such as across a continent or an ocean, where much deviation won’t be required. A fatigued pilot cannot perform top-notch decision-making, which can compromise the safety of the passengers and the flight. 

Autopilot During Turbulence  

In turbulence, updrafts and downdrafts are prevalent, but the autopilot still flies the aeroplane at the assigned altitude and keeps the airplane on the programmed route. Turbulence can take its toll on human pilots but not on autopilot. However, in cases of extremely heavy turbulence, pilots may deactivate the system and fly the plane themselves, as the autopilot may execute too many course corrections very rapidly, causing discomfort for the passengers. 

Autopilot During Emergency  

In cases of emergency, like a passenger or a crew member falling ill, there is an extensive list of mandatory communications required by the flight deck crew, like enquiring about a doctor on board or someone with medical experience. An emergency landing may also be needed, and the captain would need to coordinate and assess the situation both on board and on the ground. An autopilot is extremely useful in this case.
