With the engine start lever in IDLE and the engine operating, ignition to the selected igniter only occurs when the engine start switch is in which position?

With the engine start lever in IDLE and the engine operating, ignition to the selected igniter only occurs when the engine start switch is in which position?

• A. IDLE
• B. CONT
• C. FLT
• D. GRD

Answer: (B)

Ignition is controlled by the engine start switch. The igniter circuit is energized only in the continuous ignition position, which powers the selected igniter continuously to allow relight or ignition during critical conditions. When the switch is in idle, flight, or ground, the igniter is not powered, so ignition to the selected igniter occurs only in the continuous position. This provides ready ignition capability if a flameout occurs, while avoiding unnecessary sparking during normal operation.
