Emergency landing refers to a situation in aviation where an aircraft is forced to land unexpectedly due to various critical circumstances, including mechanical failure, medical emergencies, adverse weather conditions, or other unforeseen problems that compromise the safety of the flight. During an emergency landing, pilots execute procedures to minimize risk and ensure the safety of passengers and crew. This may involve landing at the nearest suitable airport or, in certain cases, performing a controlled landing in an unprepared area. Emergency landings are carefully coordinated, and pilots are trained to handle such situations to mitigate potential dangers.
