In aviation terms, what is the relationship between stall speed and ice on the wing?

The correct relationship between stall speed and ice on the wing is that ice increases stall speed. When ice accumulates on the wings of an aircraft, it disrupts the smooth airflow necessary for generating lift. This disruption leads to an increase in the stall speed, which is the minimum speed at which an aircraft can maintain controlled flight.

The presence of ice alters the wing's aerodynamic properties, making it more challenging to achieve the critical angle of attack without stalling. As a result, the aircraft must fly at higher speeds to maintain the lift required for flight, thus increasing the stall speed. Understanding this relationship is essential for pilots, as it highlights the dangers of flying in icy conditions and the importance of regular pre-flight inspections to ensure the airframe is free of ice.
