Wing Anti-Icing System Components

Icing conditions exist when the Static Air Temperature (SAT) on the ground and in flight is between 10°C (50°F) and -40°C (-40°F), and visible moisture in any form is present.

The ice detector probes are mounted on each side of the fuselage just below the pilot and copilot windows. They measure ice accumulation on the tip of each probe, and ice formation on the probes changes the resonant properties of the probe, proportional to the accumulation thickness.

The ice thickness affects the resonate properties of the detectors, which in turn determines the thickness of the ice.

<p>The system activates when probes accumulate 0.020 inches (0.508mm) of ice formation, decreasing the probe frequency by approximately 130 Hz.</p> Signup and view all the answers
