Landing speed refers to the velocity at which an aircraft approaches the runway for landing. This speed is crucial for ensuring a safe touchdown, as it affects the aircraft's control and stability. Factors such as the aircraft's weight, weather conditions, and runway length can influence the required landing speed. Pilots calculate landing speed using specific guidelines provided in the aircraft's operating manual. This speed is typically lower than the aircraft's cruising speed and is adjusted based on various conditions. Proper management of landing speed helps prevent accidents and ensures a smooth landing for both the aircraft and its passengers.
