Fuel metering valve actuator initiated built in test

A fuel actuation system comprising:

• a servo valve (SV) including a torque motor and at least one screen;
• a metering valve (MV) fluidly connected to the SV;
• and
• an electronic engine control (EEC) operatively connected to the SV, the EEC being configured and disposed to:
• determine at least one of a travel time of the MV, a travel distance of the MV, a pressure of a fuel, or a temperature of the fuel;
• store the at least one of the travel time of the MV, the travel distance of the MV, the pressure of the fuel, and the temperature of the fuel to a memory to generate at least one of a travel time history, a travel distance history, a fuel temperature history, and a fuel pressure history;
• and
• determine a level of degradation of the fuel actuation system based on the at least one of the travel time history, the travel distance history, the fuel temperature history, or the fuel pressure history.
