RTCA DO-160 – Section 24.0 – Icing

 

These tests determine performance characteristics for equipment that must operate when exposed to icing conditions that would be encountered under conditions of rapid changes in temperature, altitude and humidity.
Three icing test procedures are specified according to the category for which the equipment is designed to be used and installed in the aircraft (see Subsection 24.3).
Note: The selection of icing category depends on equipment location in (or on) the aircraft and the type of icing conditions expected. These conditions must be considered by the equipment designer in evaluating these requirements, which are determined by the end application and use of the equipment. These tests generally apply to equipment mounted on external surfaces or in non-temperature controlled areas of the aircraft where rapid changes in temperature, altitude and humidity are generally encountered.
These procedures specify test methods for evaluating the effects of various icing conditions on the performance or aircraft equipment, namely:
  1. The effects of external ice or frost adhering to it
  2. The effects of ice caused by freezing of water condensation or by re-freezing of melted ice
  3. The effects of ice build-up caused by direct water exposure

 

DO-160 is a standard for environmental test on avionics equipment published by RTCA, the Radio Technical Commission for Aeronautics. The DO 160 G was amended and now all guideline inside it are replaced by the DO 357.
On our website you can find only some abstracts of the document, for the full text of the guideline you have to purchased it from RTCA.
We remember you that now DO 160 G cannot be read without DO 357.
If you need any interpretation regarding the text of such standard, please contact CELAB.
CELAB is the only Italian (and one of the few European) member of the RTCA Special Committee 135, the commettee for devolpment of DO 160 G.
