Abstract	This presentation details the history and development of the USAF Total In-Flight Simulator (TIFS) over a period of over 30 years. This includes the description of two of the most recent programs conducted on the aircraft. These programs include the X-40 IAG&C Autoland demonstration and the ITT Viking Airborne Natural Gas detection system. The TIFS was developed in the 70’s with its twin the CTIFS. The TIFS has been in operation for over 30 years. In 1998 the TIFS was modified with its new simulation cockpit nose in support of the NASA HSCT program. The USAF discontinued operation of the TIFS in 1998 and Calspan took over operation of the aircraft under a CRADA with the USAF in 1999, an N-number was assigned by the FAA in January 2001. The first program conduced under the CRADA was the X-40IAG&C Autoland demonstration. This program was a risk reduction program which showed the IAG&C algorithm could accommodate single and multiple control surface failures, reconfigure the flight control system and the trajectory as necessary to provide an acceptable touchdown location and sink rate. This program also demonstrated autonomous steep approaches to touchdown under control of the IAG&C controller without pilot intervention. The second program was the ITT Viking Airborne Natural Gas detection system. This program utilized the avionics nose and installed over 2200 lbs of equipment in the TIFS. This program was a quick turn type of program typical of the TIFS with an initial enquiry of the feasibility and cost of the TIFS operation in January 04 with the completion of the flight test program in September ’04. A successful demonstration of the Viking system was completed with the Viking detecting all leaks at the Cheyenne range as well as others which the DOE did not know about. The performance capabilities of the aircraft were also provided and two videos of the TIFS program were shown. The TIFS is available as an In-Flight Simulator as well as a test platform for other programs.
