Once airborne, MWS ON allows automatic dispensing of expendables if the MODE switch is in which position?

For the C-17 aircraft's Multi-Weapon System (MWS), the automatic dispensing of expendable countermeasures is a crucial function designed to enhance survivability against threats. When the MWS ON is activated, and the MODE switch is set to AUTO, it enables the system to automatically deploy flares or chaff in response to detected incoming threats. This automated response increases reaction time and allows the pilot and crew to focus on flying the aircraft and managing other critical tasks rather than manually deploying countermeasures.

In AUTO mode, the system analyzes sensor data to assess the level of threat and dispatches the appropriate countermeasures without requiring direct intervention from the aircrew. This capability is essential for maintaining situational awareness and maximizing the effectiveness of the countermeasures in real-time combat scenarios.
