Two crucial pieces of miscommunication led to the disaster of Avianca Flight 52. When the aircraft was passed to local air traffic controllers, they were not informed it had little fuel to reach an alternative airport. Also, the crew did not declare a "fuel emergency," which would have signaled the danger. As a result, the plane was given a landing pattern it lacked enough fuel to execute, and the engines flamed out on approach, causing the plane to crash and kill 65 passengers and 8 crew. The document discusses how miscommunication can easily occur and have severe consequences, especially in high-risk fields like air travel, where even small errors can lead to tragedy.
