Abstract

A system for controlling operation of engines of a multi engine aircraft includes an idle cruise regimen controller configured to actuate exit of a selected engine from a standby mode of operation. The idle cruise regimen controller is further configured to increase a maximum gas generator speed limit (NHMAX) of the selected engine from a standby mode level (604) to a predetermined exit limit (612), decrease a maximum torque limit (QMAX) of the selected engine to 20% of a maximum torque level (614), maintain the maximum torque limit (QMAX) of the selected engine at the 20% of the maximum torque level (614) for a predetermined warm up period, increase a gas generator speed (NH) of the selected engine to a first gas generator speed level (616), increase the maximum torque limit (QMAX) to a maximum torque level (600) and increase a speed of the selected engine to a re-engagement speed responsive to increasing of the maximum torque limit (QMAX).
