A method detects an impendent situation of an operating aircraft. The method comprises receiving data corresponding to a plurality of parameters related to an operation of the aircraft. It is determined if any of the plurality of parameters is at or beyond at least a first respective threshold by comparing the plurality of parameters with the first respective thresholds. If at least one of the parameters is an outlier parameter at or beyond its first respective threshold, another or others of the plurality of parameters associated to the at least one outlier parameter is identified, the at least one other parameter being selected based on a predetermined combination of parameters representative of an adverse condition. The associated parameters are compared with a stored data combination threshold specific to the associated parameters. A signal indicative of an impending situation is output if the associated parameters are on or beyond the data combination threshold. A system and an aircraft detecting an impendent situation are also provided.
