A method for detecting erroneous air data on an aircraft includes determining a current air parameter and a current altitude pressure parameter which collectively define a current point of control for the aircraft. The method also includes verifying whether the current point of control is situated in a characteristic envelope indicating operating limits for the aircraft. When the current point of control is outside the characteristic envelope, then a detection piece of information identifying at least one of the parameters as an erroneous parameter is emitted, which causes that erroneous parameter to be invalidated and an alarm signal to be sent to the crew. Therefore, an erroneous air data parameter is readily addressed and discarded using the method and associated device.
