What are the two positions of the ignition switch?

The ignition switch in the T-6A is designed to have two primary positions: NORM and ON. The NORM position is used for the regular operational state of the aircraft, allowing the system to perform its necessary functions, such as providing power to essential electrical components and indicating that the engine can be started. When the switch is in the ON position, it primes the ignition system and engages the fuel system, which is critical for the engine to function correctly when starting.

Understanding these positions is vital for pilots as they work through the startup and pre-flight procedures. The operational state allows for proper engine management and ensures that all systems are taking in the necessary power without any unwanted disruption. Knowing the function of these positions aids in maintaining the aircraft's readiness for flight while ensuring safety and efficiency in operations.
