A320 Ice Indicator

Here's a detailed overview of how to interpret the Ice Indicator on an A320 aircraft: Ice Accumulation Detection System (IADS) - The IADS consists of two sensors, one located near the nose gear and the other near the tail gear. These sensors detect ice accumulation on the wing tips. Ice Detection Algorithm - The IADS uses a sophisticated algorithm to analyze data from the sensors and determine if ice has accumulated on the wing tips. This information is then displayed on the Ice/ Rain Detector (IRD) located in the cockpit. IRD Display - The IRD display indicates whether ice or rain is detected, as well as the amount of accumulation. The display also shows an "ICE" indication when ice is present. Ice Accumulation Warning - If the IADS detects a significant amount of ice accumulation, it will trigger an Ice Accumulation Warning (IAW). This warning alerts the pilots to take action to prevent icing conditions from affecting the aircraft's performance. Icing Conditions Classification - The IADS classifies icing conditions into three categories: Light, Moderate, and Severe. This classification is based on the amount of ice accumulation detected by the sensors. Pilot Action Required - If the IADS detects severe icing conditions, pilots must take immediate action to prevent damage to the aircraft's airframe and engines. This may include reducing speed, increasing power, or descending to a lower altitude.
