What is the maximum speed for takeoff with the ADG in the CRJ 900/700?

The maximum speed for takeoff with the Automatic Dependent Surveillance–Broadcast (ADG) in the CRJ 900/700 is determined by the aircraft's VMO (Maximum Operating Limit Speed) and MMO (Maximum Operating Mach Number). These speeds represent the absolute boundaries for safe flight operations during different phases, including takeoff.

Choosing VMO/MMO as the correct answer reflects an understanding that these values encompass both airspeed in knots (KIAS) and Mach number, ensuring safe maneuverability and adherence to performance limitations. Exceeding these limits, especially at critical phases like takeoff, could compromise safety and performance, which makes this choice the most appropriate in this context. The other options, while they mention specific speeds, do not account for the comprehensive operational limits that VMO and MMO provide.
