FIELD: heating.
SUBSTANCE: group of inventions relates to a heating apparatus for the use with an angle of attack sensor, system with an angle of attack sensor, method of heating an angle of attack sensor, method of protecting the operation of an angle of attack sensor. Heating apparatus comprises a support element, a heating element, a control thermostat. System comprises an angle of attack sensor with a body in the form of an aerodynamic surface attached to a rotatable mount, heating apparatus comprising a support element, heating element and control thermostat. To heat an angle of attack sensor, data about the temperature of the surface of an angle of attack sensor is received, flow of current through the heating element of the heating device is provided and regulated in a certain manner. Sensor body is placed on the outer surface of the protective plate to protect the operation of an angle of attack sensor under freezing conditions, an angle of attack sensor is placed inside the case attached to the inner surface of the protective plate, heating apparatus is attached to the outer part of the case and the heating apparatus is controlled to maintain a certain temperature in a certain manner.
EFFECT: reliability of an angle of attack sensor is increased.
