The MD-1110 is an upgrade to add a [[glass cockpit]] to the DC-10 with the re-designation to ''MD-1110''. The upgrade included an Advanced Common Flightdeck used on the MD-11 and was launched in September 1996.<ref name=MD-10_launch>[http://www.boeing.com/news/releases/mdc/96-231.html "McDonnell Douglas and Federal Express to Launch MD-1110 Program"] {{webarchive |url=https://web.archive.org/web/20111106194647/http://www.boeing.com/news/releases/mdc/96-231.html |date=November 6, 2011}}.

This has allowed companies such as [[FedEx Express]], which operated both the MD-10 and MD-11, to use a common pilot pool for both aircraft. The MD-10 conversion now falls under the Boeing Converted Freighter program where Boeing's international affiliate companies perform the conversions.<ref>[http://www.boeing.com/news/releases/2008/q2/080616a_nr.html "World's First 767-300 Boeing Converted Freighter Goes to ANA"] {{webarchive |url=https://web.archive.org/web/20080622133532/http://www.boeing.com/news/releases/2008/q2/080616a_nr.html |date=June 22, 2008}}.
