What happens if the Pilot Side Switch on the Guidance Panel is changed during a 30-degree bank?

When the Pilot Side Switch on the Guidance Panel is changed during a 30-degree bank, the Flight Director defaults to ROLL mode. This mode is designed to maintain the current bank angle that the aircraft is experiencing at the moment the switch is changed. Therefore, if the aircraft is in a 30-degree bank and the switch is altered, the Flight Director keeps the aircraft in that bank until the pilot commands otherwise or the condition changes.

This understanding is crucial for pilots operating in dynamic environments where quick adjustments are necessary. Maintaining awareness of the controls and their effects on aircraft handling is essential for safe flight operations. In contrast, options discussing transitioning to PATH mode, reducing the bank angle, or automatically engaging the autopilot do not accurately describe the behavior of the Flight Director in this scenario. Each of those alternatives misrepresents how the system is designed to operate during this specific action.
