Which condition will cause ignition to both igniters when ignition L/R is selected?

• A. CONT
• B. GRD
• C. FLT
• D. IDLE

Answer: (C)

Ignition control is designed for redundancy and reliability across different operating states. When the system is in flight mode, the logic is set to energize both igniters to maximize the chance of a successful ignition under harsher conditions such as higher airflow and more variable environment. Even if you have selected a specific igniter (left or right), flight mode overrides that to fire both sparks for robustness. The other modes serve different purposes—continuous ignition simply keeps sparks on, while ground and idle modes typically use only the selected igniter to save power and reduce wear. So the condition that makes both igniters fire is flight.
