De-icing is the process of removing snow, ice or frost from a surface. Anti-icing is 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.

The golden jackal (Canis aureus), also called the common jackal, is a wolf-like canid that is native to Eurasia. The golden jackal's coat varies in color from a pale creamy yellow in summer to a dark tawny beige in winter. It is smaller and has shorter legs, a shorter tail, a more elongated torso, a less-prominent forehead, and a narrower and more pointed muzzle than the Arabian wolf. It is listed as Least Concern on the IUCN Red List due to its widespread distribution and high density in areas with plenty of available food and optimum shelter.

Despite its name, the golden jackal is not closely related to the African black-backed jackal or the side-striped jackal, which are part of the genus Lupulella. It is instead closer to wolves and coyotes. The ancestor of the golden jackal is believed to be the extinct Arno river dog that lived in southern Europe 1.9 million years ago. It is described as having been a small, jackal-like canine. Genetic studies indicate that the golden jackal expanded from India around 20,000 years ago, towards the end of the last Last Glacial Maximum. The oldest golden jackal fossil, found at the Ksar Akil rock shelter near Beirut, Lebanon, is 7,600 years old. The oldest golden jackal fossils in Europe were found in Greece and are 7,000 years old. There are six subspecies of the golden jackal. It is capable of producing fertile hybrids with both the gray wolf and the African wolf. Jackal–dog hybrids called Sulimov dogs are in service at the Sheremetyevo Airport near Moscow, where they are deployed by the Russian airline Aeroflot for scent-detection.

An air operator's certificate (AOC) is the approval granted by a civil aviation authority (CAA) to an aircraft operator to allow it to use aircraft for commercial air transport purposes. This requires the operator to have personnel, assets and systems in place to ensure the safety of its employees and of the flying public. The certificate lists the approved aircraft types, each registration number approved to fly, the approved flying purpose, and in what area the holder may operate (such as specific airports or geographic region).

The Tupolev Tu-154 (Russian: Tyполев Ту-154; NATO reporting name: "Careless") is a three-engined, medium-range, narrow-body airliner designed in the mid-1960s and manufactured by Tupolev. A workhorse of Soviet and (subsequently) Russian airlines for several decades, it carried half of all passengers flown by Aeroflot and its subsidiaries (137.5 million/year or 243.8 billion passenger-km in 1990), remaining the standard domestic-route airliner of Russia and former Soviet states until the mid-2000s. It was exported to 17 non-Russian airlines and used as a head-of-state transport by the air forces of several countries.

The aircraft has a cruising speed of 850 km/h (460 kn; 530 mph) and a range of 5,280 km (3,280 mi). Capable of operating from unpaved and gravel airfields with only basic facilities, it was widely used in the extreme Arctic conditions of Russia's northern/eastern regions, where other airliners were unable to operate. Originally designed for a 45,000-hour service life (18,000 cycles), but capable of 80,000 hours with upgrades, it was expected to continue in service until 2016, although newer noise regulations have restricted it from flying to Western Europe and other regions.
