In the inertia starter, energy is stored slowly during an energizing process by a manual hand crank or electrically with a small motor. (TRUE OR FALSE)

Answer 30

TRUE

Question 31

The starter must turn the engine up to a speed that provides enough electricity through the engine for fuel to be ignited. Then, the starter must continue to help the engine accelerate to a self sustaining speed. Turbine engine starters have a critical role in starting of the engine. (TRUE OR FLASE)
