What speed must not be exceeded for maximum landing gear retraction (Vlo)?

The maximum landing gear retraction speed, also known as Vlo, is a critical limitation for ensuring safe operation during landing gear operations. For the King Air 350, this speed is set at 166 KIAS (Knots Indicated Airspeed). This limitation is established to prevent structural damage and ensure proper functioning of the landing gear mechanism during the retraction phase.

Exceeding this speed could lead to increased aerodynamic forces that may cause the landing gear to not retract properly or could potentially damage the gear mechanism. The gear retraction system is designed to operate within a specific speed range, and staying below Vlo ensures reliable performance during this critical phase of flight. Thus, understanding the importance of adhering to this limitation helps pilots maintain safe operational practices.
