What is the maximum speed for landing gear retraction (Vle) in the ERJ 170/175?

The maximum speed for landing gear retraction in the ERJ 170/175 is defined as Vle, which stands for "Maximum Landing Gear Extended Speed." This important limitation ensures that when the landing gear is being retracted, the aircraft does not exceed the maximum speed that could cause mechanical failure or damage to the landing gear mechanism.

In the ERJ 170/175, the maximum speed for gear retraction is set at 250 KIAS (Knots Indicated Airspeed). This allows pilots to safely retract the landing gear while maintaining an appropriate airspeed, which is vital during ascent after takeoff. Exceeding this speed could lead to increased aerodynamic forces on the landing gear, potentially leading to structural failure or difficulties in gear operation.

The other speeds listed do not align with the manufacturer's specified limitation for safe gear retraction. Maintaining awareness of these limitations is crucial for pilots to ensure safe operation of the aircraft.
