Рассмотрены особенности этих сертификационных требований и их влияние на три основных направления сертификации воздушных судов (ВС) для условий обледенения: в части системы сигнализации обледенения, системы воздушных сигналов, а также противообледенительной системы. Показано, что влияние новых требований не сказывается на сертификации датчиков системы воздушных сигналов, однако оказывается существенным для двух других направлений. Для безопасной эксплуатации ВС важно своевременное срабатывание системы сигнализации обледенения. Ранее была разработана методика, обеспечивающая это в условиях Приложения С к АП/CS/FAR-25. Отмечено, что методика работоспособна и для новых условий обледенения, но с учетом соответствующих изменений в расчетах нарастания ледяных отложений на сигнализаторе обледенения, воздухозаборнике двигателя и несущих поверхностях. Одной из проблем является обнаружение момента попадания в условия обледенения, определенные новыми требованиями, что в значительной степени определяет возможность немедленного покидания зоны обледенения в том случае, если самолет не удовлетворяет требованиям безопасной эксплуатации в таких условиях. Описаны способы удаления ледяных отложений с несущих поверхностей. Рассмотрен случай обледенения поверхности крыла за предкрылком, в том числе с образованием барьерного льда. Оценена возможность эксплуатации ВС без ограничений в условиях обледенения, определенных новыми сертификационными требованиями.</p></abstract><trans-abstract xml:lang="en"><p>Due to the implementation of new certification requirements for icing conditions provided in Annex О to CS-25, there is a necessity to analyze the impact of the requirements on the possibility of transport aircraft certification for flights under such conditions. The particularities of such certification requirements and their impact on three main directions of aircraft certification have been considered for icing conditions: icing annunciation system, air data system and anti-icing system. It has been shown that new requirements have no effect on certification of air data system sensors but they have an impact on icing annunciation and antiicing system. Timely annunciation of icing is important for safe operation of aircraft. The procedure providing timing annunciation was developed earlier in Annex C to AR/CS/FAR-25. It is highlighted that this procedure is also actual for new icing conditions but taking into account relevant updates in calculations of the growth of ice accretions on ice detectors, air inlets and lifting surfaces. One of the problems is to detect the moment of coming into icing conditions, determined by new requirements. It substantially determines the possibility of immediate escape from icing area if the airplane does not meet the safe operation requirements for such conditions. The techniques of removing ice accretions from lifting surfaces are described. The case of icing the wing surface behind the slats area with barrier ice accumulation was studied. The possibility of an aircraft limitless operation under icing conditions determined by new certification requirements was estimated.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>воздушное судно</kwd><kwd>безопасность полета</kwd><kwd>сертификационные требования</kwd><kwd>условия обледенения</kwd><kwd>аэродинамические характеристики</kwd><kwd>датчики системы воздушных сигналов</kwd><kwd>ледяные наросты</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aircraft</kwd><kwd>flight safety</kwd><kwd>certification requirements</kwd><kwd>icing conditions</kwd><kwd>aerodynamic performance</kwd><kwd>air data system sensor</kwd><kwd>ice accretion</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Шевяков В.И.
