Experts conducted a study among 22 airports in the 20 largest cities of Russia in order to clarify the development of infrastructure for people with disabilities, according to the news portal Interfax. The study is dedicated to the International Day of Persons with Disabilities, which is celebrated on December 3rd. According to the study, only two thirds of airports are fully equipped to serve persons with physical disabilities. 27% of the harbors are not equipped with ambulifts, which are used to lift the wheelchairs on board the aircraft in case of landing without a sleeve. The same number of air ports does not provide navigation for people with visual and hearing aid limitations. It is worth noting that 91% of airports have special parking spaces, and escort services can be ordered free of charge at Krasnoyarsk Airport.
