What is the climb speed for the aircraft in ice mode with flaps at 0º?

The climb speed for the aircraft in ice mode with flaps at 0º is indeed 135 knots. This speed is critical for ensuring optimal performance during climb, especially in icing conditions where the aircraft’s aerodynamic characteristics can be adversely affected by ice accumulation.

When flying in ice mode, it is necessary to consider the changes in lift and drag caused by the additional weight and altered airflow over the wings due to ice. Climbing at 135 knots allows the aircraft to maintain a safe margin above stall speed while also maximizing climb performance. It helps ensure that the aircraft has sufficient power and lift to counteract the negative impacts of ice, thereby enhancing safety and operational effectiveness.

In contrast, selecting climb speeds significantly higher or lower than this could lead to inadequate climb performance or increased risk during flight under these conditions. Therefore, 135 knots is the established threshold that has been determined to provide a balance between safety and performance when dealing with the particular challenges of climbing in icing situations.
