What is the climb speed pusher ice mode with flaps at 0º?

The climb speed pusher ice mode with the flaps set at 0º is specifically designed to ensure safe climb performance when the aircraft encounters ice conditions. The correct value of 135 knots is critical because this speed has been determined through operational testing to provide an adequate safety margin while allowing for effective climb performance under these specific conditions.

When the aircraft is encountering ice, maintaining the appropriate speed is vital to prevent a stall and to ensure that the wings retain sufficient lift. Climb speed pushers are mechanisms in the aircraft's flight control system designed to automatically prevent the aircraft from descending below this critical speed. Selecting the correct speed also takes into account the plane’s handling characteristics when ice accumulation might alter its aerodynamic properties.

For safe operational practices, knowing this speed is essential for flight crews operating under Part 135 regulations, ensuring they comply with safety procedures while handling various flight conditions. Understanding the intricacies of flight operations in varying conditions, especially with respect to ice, enhances situational awareness and ultimately contributes to safer flying practices.
