Abstract
A method is provided for operating an aircraft system. During this method, a first temperature of a lubricant is determined. The aircraft system is operated in a first warmup mode when the first temperature of the lubricant is below a first threshold. The operating of the aircraft system in the first warmup mode includes driving rotation of a rotating structure about an axis and heating the first quantity of the lubricant contained in the first reservoir using a first electric heater. A startup of the turbine engine is initiated following the operating of the aircraft system in the first warmup mode.
