SA-097 emphasizes “as little as 1/4 -inch of wing-leading edge ice accumulation can increase the stall speed by 25 to 40 knots and cause sudden departure from controlled flight.” The alert also warns that Ice buildup on pitot tubes can lead to instrument failure, impacting readings for airspeed, altitude, and vertical speed.

Ram air from a pitot tube and static (undisturbed) outside air from a static port, usually a hole on the side of the fuselage. Airspeed indicators need air from a pitot tube and static air from a static port Small general aviation aircraft have airspeed indicators with air hoses connected directly to the pitot and static sources.

Moving air from outside feeds into the pitot tubes and fills a pressure diaphragm. The sensor detects the amount of force from the pitot impact pressure and gives it airspeed indications by converting those values into speed. As altitude increases, the stall speed decreases as there is less air resistance.
