System and method for purging a fuel manifold of a gas turbine engine through a flow divider valve

A method of operating a multi-engine power plant of an aircraft, the multi-engine power plant including a first gas turbine engine (FGTE) and a second gas turbine engine (SGTE), the FGTE and SGTE being drivingly connected to a common load, the method comprising:

• operating the FGTE and the SGTE to drive the common load, wherein operating the SGTE includes supplying fuel to a combustor of the SGTE by supplying fuel to a first fuel manifold and a second fuel manifold of the SGTE via a common flow divider valve;
• and
• while operating the FGTE and supplying fuel to the combustor of the SGTE by supplying fuel to the first fuel manifold of the SGTE via the common flow divider valve:
• stopping supplying fuel to the second fuel manifold of the SGTE via the common flow divider valve, and
• supplying pressurized gas to the second fuel manifold of the SGTE via the common flow divider valve to flush fuel in the second fuel manifold into the combustor of the SGTE.
