At what speed does the takeoff CAS message inhibit feature activate?

The takeoff CAS message inhibit feature activates at a speed of 80 knots. This feature is crucial for improving pilot workload management during the takeoff phase, as it prevents non-critical alerts from being displayed in the cockpit when the aircraft is transitioning from the ground to the air.

At speeds below this threshold, certain warnings or alerts that are not immediately relevant to the takeoff may distract the pilots. Therefore, the system is designed to inhibit such messages starting at 80 knots, allowing pilots to focus on the critical aspects of takeoff without unnecessary disturbances. This activation point ensures that the focus remains on the essential tasks at hand, such as speed, altitude, and navigation.

As the aircraft reaches and exceeds this speed, the system resumes normal operation, allowing relevant alerts to be displayed that may require the pilot's attention once airborne. This strategic design enhances safety and efficiency in flight operations during a crucial phase of flight.
