Is Vlo RET higher or lower than Vlo EXT?

In the context of the CRJ 200, Vlo RET refers to the landing gear retraction speed, while Vlo EXT refers to the landing gear extension speed. The landing gear retraction speed (Vlo RET) is indeed lower than the landing gear extension speed (Vlo EXT).

The reason for this relationship is primarily based on aerodynamic and structural considerations. During gear retraction, the aircraft is typically in a configuration that can be less stable and may face more aerodynamic loads, requiring a lower speed to ensure safe operation. Conversely, the gear must be fully extended at a higher speed to allow for proper deployment and to handle the loads associated with the aircraft in its landing configuration.

Understanding the operational limitations, including these speeds, is essential for safe flight operations as they dictate the conditions under which the gear can be safely retracted or extended.
