The Loening C-4C, later the Keystone-Loening K-85 Air Yacht following the merger of the Loening and Keystone companies, was an amphibious utility biplane built in the United States in the late 1920s. It was developed by Grover Loening from the C-1 that he had created together with Leroy Grumman, incorporating a new fuselage design. This departed from the characteristic Loening design feature of having a slender, "shoehorn" float projecting from the underside of the fuselage with an engine mounted tractor-fashion above it. Instead, the C-4C had a conventional flying-boat hull, with an enclosed cabin for passengers. The engine was mounted in a separate nacelle on the leading edge of the upper wing. Two C-4Cs were built in 1928, shortly before the corporate merger. In 1931, Keystone-Loening built two examples of a revised version, but no further production ensued. Thompson Aeronautical Corporation (TAC), a U.S.-based air carrier, was operating scheduled passenger service between Detroit and Cleveland in 1930 with Keystone–Loening Air Yacht aircraft with six round trip flights a day between the two cities.[1] Specifications (K-85 Air Yacht){{aerospecs|ref= |met or eng?=eng |crew=One pilot |capacity=7 passengers |length m=11.33 |length ft=37 |length in=2 |span m=14.22 |span ft=46 |span in=8 |swept m= |swept ft= |swept in= |rot number= |rot dia m= |rot dia ft= |rot dia in= |dia m= |dia ft= |dia in= |width m= |width ft= |width in= |height m= |height ft= |height in= |wing area sqm= |wing area sqft= |swept area sqm= |swept area sqft= |rot area sqm= |rot area sqft= |volume m3= |volume ft3= |aspect ratio= |wing profile= |empty weight kg= |empty weight lb= |gross weight kg= |gross weight lb= |lift kg= |lift lb= |eng1 number=1 |eng1 type=Wright Cyclone |eng1 kw=390 |eng1 hp=525 |eng1 kn= |eng1 lbf= |eng1 kn-ab= |eng1 lbf-ab= |eng2 number= |eng2 type= |eng2 kw= |eng2 hp= |eng2 kn= |eng2 lbf= |eng2 kn-ab= |eng2 lbf-ab= |max speed kmh=210 |max speed mph=130 |max speed mach= |cruise speed kmh= |cruise speed mph= |stall speed kmh= |stall speed mph= |range km=800 |range miles=500 |endurance h= |endurance min= |ceiling m= |ceiling ft= |g limits= |roll rate= |glide ratio= |climb rate ms= |climb rate ftmin= |sink rate ms= |sink rate ftmin= |armament1= |armament2= |armament3= |armament4= |armament5= |armament6= }}{{aircontent |see also= |related= |similar aircraft= |lists= }} References1. ^http://www.timetableimages.com, 1930 Thompson Aeronautical Corp. timetable {{commons category|Keystone–Loening Air Yacht}}
