When using the training switch, the idled engine spools down to ____ RPM N2 at a preprogrammed rate.

• A. 320 RPM
• B. 300 RPM
• C. 260 RPM
• D. 360 RPM

Answer: (A)

When you engage the training switch, the engine control uses a dedicated idle schedule that decelerates the engine to a fixed, low N2 value. This creates a stable, repeatable idle condition specifically for training. The idled engine spools down to 320 RPM N2 because that is the defined training idle point for this aircraft, ensuring enough bleed air, lubrication, and system readiness while keeping the engine in a safe, low-power state for training events. The rate of deceleration is preprogrammed so each training cycle behaves the same, giving predictable engine behavior during exercises. Values outside this range wouldn’t represent the standard training idle—too low could risk flameout or insufficient system operation, too high would not simulate idle conditions accurately.
