An aircraft propulsion control system for an aircraft having a plurality of combustion engines is provided. The system has a plurality of sensors for sensing a condition indicative of properties and/or formation of vapour trails which may be formed by the plurality of engines. A controller is arranged to control one or more operational variable for each of the plurality of engines. The controller is arranged to undertake a search of trial values of the operational variable by instructing different concurrent values of said operational variable across the plurality of engines and determining the resulting impact on the vapour trail formation and/or properties as sensed by the sensors. A population-based search may be performed, for example in parallel over all the engines at once so as to reduce the time taken to achieve vapour trail mitigation.
