Abstract: the ice detector of Airbus A320 aircraft is introduced 1、 Working principle of ice detector and ice sensor: the electronic ice detector installed on A320 aircraft is usually vibration principle, that is, the detector vibrates at a higher frequency when it is normally powered on. When the detector freezes, the vibration frequency will be reduced, so it can be judged that the aircraft has entered the icing area. The electronic ice detector is an optional part of Airbus aircraft. It is installed on the inside of Tat probe near the total atmospheric temperature sensor.

Ice detector and ice sensor of Airbus aircraft

-Introduction of icing detector for A320 aircraft




1、 Working principle of ice detector and ice sensor: the electronic ice detector installed on A320 aircraft is usually vibration principle, that is, the detector vibrates at a higher frequency when it is normally powered on. When the detector freezes, the vibration frequency will be reduced, so it can be judged that the aircraft has entered the icing area. At the same time, the detector will display a warning message on the E / WD:

1. "Ice detected";

2. "Severe ice detected";

3. "Ice detect fault";

It should be noted that the ice detection system does not control the engine or wing anti icing system, they are independent.

2、 A320 aircraft icing detector | ice sensor

The electronic ice detector is an optional part of Airbus aircraft. It is installed on the inside of Tat probe near the total atmospheric temperature sensor.

1. Civil aircraft equipped with ice detector and ice sensor

 

2. Civil aircraft without ice detector and ice sensor


3、 Visual icing detector in Airbus A320 aircraft, in addition to electronic ice detector and ice detector, there are also visual ice detector. It has a simple structure and is installed between the two front windshields.


4、 The harm of aircraft icing

In September every year, the annual aircraft de icing and anti icing training work of the engineering and maintenance department of the airline is about to start, and the harm of aircraft icing is self-evident

1. The performance of the aircraft is reduced;

2. Changed flight characteristics;

3. The range of motion of the control surface is limited;

4. Causing instrument error;

5. Cause engine failure.

In the history of civil aviation, there have been many air accidents caused by aircraft icing. Therefore, as the maintenance personnel, we need to pay more attention to the work of aircraft deicing and anti icing. On the afternoon of March 1, 2021, the b-10gd aircraft of Beidahuang general aviation company, which was rented by Jiangxi Meteorological Bureau, suddenly fell down while carrying out the artificial precipitation task over Ji'an County, Jiangxi Province. Five people died in the accident, including two flight crew members, three meteorological workers, and one local resident with less than 10% of the body surface caused minor injuries. The "China Civil Aviation Safety Information System" sponsored by the Civil Aviation Administration of China recently released the investigation report of the accident. The investigation team believes that during the implementation of artificial precipitation enhancement, the aircraft wing and propeller were seriously frozen after flying under icing conditions for a long time, and the crew failed to effectively control the risk of aircraft icing, and then the aircraft stalled and entered the spiral, and eventually fell to the ground and caught fire.
