Kacha is not only aircraft but helicopters as well. Over here, in Crimea, such sorts of aircraft as search-and-rescue KA-27PS helicopters, antisubmarine KA-27PL and multipurpose MI-8 ones. Next chopper is KA-27PL, where ‘PL’ in Russian means ‘antisubmarine.’ They are kinda look-alike with its buddy KA-27PS and only radiolocator shell gives it away. There is a special winch fixed up in the cabin which douses a radio sounding device into the water at a depth of 150 meters (500 feet.) With the help of the device a soundman detects a submarine. Inside of the cabin of MI-8 adjusted an extra fuel tank. At full load the helicopter can carry 26 people.
