EGT shows only when the EEC has electrical power.

It includes items such as magnetos, distributors, booster coils, exciters, transformers, storage capacitors and compositors, etc.

That portion of the system is used to generate electrical current for the purpose of igniting the fuel mixture in the combustion chargers and thrust augmentors.

Ignition includes induction vibrators, magnetos, switches, lead filters, distributors, harnesses, plugs, ignition relays, exciters, and the electrical portion of spark advance.

That portion of the system is used to indicate the flow rate, temperature and pressure of the fuel, including items such as transmitters, indicators, etc.

The main fuel controls are used to meter fuel to the engine and to the thrust augmentor, including items such as levers, cables, pulleys, linkages, etc., which are components of the fuel control units.

The air portion includes units from the scoop inlet to the vapor vent return, and the impeller chamber.

Drive shaft section includes items such as drive shaft, adapters, seals, etc.

Accessory gearboxes do not include those accessory drives which are bolted to and are immediately adjacent to the engine.

The turbines extract energy from the exhaust gases and are coupled to the crankshaft.

The engine power system directly or indirectly indicates power or thrust, inclusive of BMEP, pressure-ratio, RPM, etc.
