What is the maximum speed for turbulence penetration in the CRJ 900/700?

The maximum speed for turbulence penetration in the CRJ 900/700 is defined as 280 KIAS or 0.75 Mach, whichever is lower. This speed is crucial for ensuring safe handling of the aircraft in turbulent conditions. It allows pilots to maintain better control without risking structural damage to the aircraft.

Operational guidelines have established this limitation to ensure that you are flying at a speed that can effectively manage the forces encountered during turbulence while also staying within the safe operational envelope. This helps in reducing the stress on both the aircraft and its passengers.

The other options do not represent the established maximum penetration speed. For instance, 250 KIAS is a speed commonly associated with altitude restrictions rather than turbulence. Similarly, the ground speed options (195 knots and 182 knots) do not pertain to the turbulence penetration speed, as these do not account for the aircraft's behavior in relation to turbulence, which is primarily assessed in terms of indicated airspeed. Thus, understanding and applying the correct maximum speed for turbulence penetration is essential for safe operations of the CRJ 900/700 series.
