Which component supplies voltage to igniter plugs?

• A. High Tension Leads
• B. Executor Assemblies
• C. Igniter Plugs
• D. FADEC

Answer: (B)

The energy that powers the spark in the ignition system comes from the ignition source hardware, housed in the executor assemblies. These assemblies generate the high-voltage energy needed for the spark and send it onward to the plugs. The high-tension leads simply carry that voltage from the executor to the igniter plugs; they don’t generate or regulate the energy themselves. The igniter plugs are the receivers that use the supplied voltage to create the spark in the combustion chamber. FADEC can control when ignition is commanded, but the actual high-voltage source for the plugs is provided by the executor assemblies.
