Anti-icing equipment is designed to prevent the formation of ice, while deicing equipment is designed to remove ice once it has formed. These systems protect the leading edge of wing and tail surfaces, pitot and static port openings, fuel tank vents, stall warning devices, windshields, and propeller blades. Ice detection lighting may also be installed on some aircraft to determine the extent of structural icing during night flights.

It should be noted that fan blade ice which may be accumulated after the pre-start visual inspection, including whilst the engines are running at low thrust prior to take off, is removed by following prescribed engine handling procedures. First of all, the aircraft must be inspected for signs of contaminant already adhering to surfaces and where found on surfaces which must be free of contaminant, it must be removed using a suitable ground de-icing fluid. Secondly, the prevailing weather conditions must be assessed. If further adherence of contaminant to the airframe surfaces is currently occurring or anticipated prior to the time at which it is expected that the aircraft will get airborne, then a suitable ground anti-icing fluid should be applied. In both cases, the time after the start of fluid treatment from which protection is provided by the fluids applied depends upon the prevailing conditions.

Anti-Ice and Deice Systems

De-icing is the process of removing snow , ice or frost from a surface. Anti-icing is understood to be the application of chemicals that not only de-ice but also remain on a surface and continue to delay the reformation of ice for a certain period of time, or prevent adhesion of ice to make mechanical removal easier. De-icing can be accomplished by mechanical methods scraping, pushing ; through the application of heat ; by use of dry or liquid chemicals designed to lower the freezing point of water various salts or brines , alcohols , glycols ; or by a combination of these different techniques.

Ему показалось, что внутри звучали какие-то голоса. Он постучал. - Hola.

 О! - Старик радостно улыбнулся.  - Так вы говорите на языке цивилизованного мира. - Да вроде бы, - смущенно проговорил Беккер. - Это не так важно, - горделиво заявил Клушар.

Бринкерхофф проследовал за Мидж в ее кабинет. Она села и начала, подобно пианисту-виртуозу, перебирать клавиши Большого Брата. Бринкерхофф посмотрел на мониторы, занимавшие едва ли не всю стену перед ее столом. На каждом из них красовалась печать АНБ. - Хочешь посмотреть, чем занимаются люди в шифровалке? - спросил он, заметно нервничая.

Я уверен. Вы должны… Сьюзан вырвала руку и посмотрела на него с возмущением. - Мне кажется, коммандер приказал вам уйти. - Но монитор.

 Мидж… я уже говорил… - Да или нет: мог в ТРАНСТЕКСТ проникнуть вирус. Джабба шумно вздохнул. - Нет, Мидж.

Сьюзан пожала плечами. - Ну, если вы имеете в виду и диагностику, то времени уходило. - Насколько. Сьюзан не понимала, к чему клонит Стратмор.

We apologize for the inconvenience...

 - Мидж, - сказал.  - Говорит Лиланд Фонтейн.

(1)Make sure that all loose snow is removed from the aircraft before you do the de-icing/anti- icing procedures. WARNING: FOR SUFFICIENT HOLDOVER TIME,​.

The accumulation of ice on structures can restrict the performance of equipment and cause other concerns in many industries such as aviation, automotive transportation, telecommunication, and defense.
