Mr. Peter de Groot's amazing photograph show the Convair 580 NC-13H with a Boeing 707 nose (see bleow - w/ fat bodies aircraft in back ground). Also could be capped with cover without any simulator. 10/06/2008 @ 16:52 [ref: 22802]

The U.S. Air Force NC-131 Total In-Flight Simulator (TIFS) Aircraft
The TIFS is the most capable in-flight simulator. It is operated by Calspan under a Cooperative Research and Development Agreement (CRADA) for the US Air Force Research Laboratory.
The TIFS is a highly modified Convair-580 (AF C-131) twin turboprop transport. Calspan finished the development of this IFS in 1970 and has operated it ever since on over 30 major aircraft development and research programs.
The TIFS unique features include a separate two-place evaluation cockpit and control over all six rigid-body degrees-of-freedom. Special aerodynamic controls (including sideforce and direct lift surfaces) and a model-following control system permit the TIFS to produce motions at the simulation cockpit that completely duplicate the computed responses of the simulated aircraft.
Its primary use has been in the development and evaluation of new aircraft flying qualities, flight controls, and cockpit displays, as well as general flight research in these areas.
A second configuration of the TIFS called the Avionics Systems Test and Training Aircraft (ASTTA) has a large avionics nose, which is interchangeable with the simulation cockpit nose. This configuration allows the addition of customer-supplied equipment such as large prototype radars, infrared cameras, and other sensors.
An instrumented crew station is installed in the aft cabin to accommodate system operators.
