Eleven
new full-color, flat-panel display screens in the Shuttle cockpit replace
32 gauges and electromechanical displays and four cathode-ray tube
displays. The new "glass cockpit" is 75 pounds lighter and uses
less power than before, and its color displays provide easier pilot
recognition of key functions. The new cockpit is expected to be installed
on all shuttles in the NASA fleet by 2002, and it sets the stage for the
next cockpit improvement planned to fly by 2005: a "smart
cockpit" that reduces the pilot's workload during critical
periods. |

This
"fish-eye" view illustrates NASA's Multifunction Electronic
Display Subsystem (MEDS), otherwise known as "glass cockpit." It
represents a number of important modifications that have been accomplished
on the Orbiter's flight deck. This photo is actually a recent one of the
fixed base Space Shuttle mission simulator in the Johnson Space Center's
(JSC) Mission Simulation and Training Facility. |

The
fixed base simulator has been outfitted with MEDS to be used by flight
crews for training. The Space Shuttle Atlantis is the only Orbiter so far
outfitted with MEDS and will fly with the new display system for the first
time late this year on STS-101. All of the Orbiters will eventually be
outfitted with the new system, which enhances safety on the Orbiter by
providing multiple backup display functions and brings the Space Shuttle
cockpit displays up to date with technology that is now common in many
commercial airliners. |

During STS-101
Atlantis will fly as the most updated shuttle ever, with more than 100 new
modifications incorporated during a ten-month period in 1998 at Boeing's
Palmdale, Ca., Shuttle factory. |
