![]() The UFDs are used to display Integrated Caution/Advisory/Warning (ICAW) data, communications/navigation/identification (CNI) data and serve as the Stand-by Flight instrumentation Group and Fuel Quantity Indicator (SFG/FQI). The two Up-Front Displays (UFDs) measure 3"x4" in size and are located to the left and right of the ICP. The lower power requirements also provide a reliability improvement over CRTs. ![]() LCDs offer lower weight and less size than the cathode ray tube (CRT) displays used in most current aircraft. ![]() These present information in full color and are fully readable in direct sunlight. There are six liquid crystal display (LCD) panels in the cockpit. Located under the glareshield and HUD in center top of the instrument panel, this keypad entry system also has some double click functions, much like a computer mouse for rapid pilot access/use. The Integrated Control Panel (ICP) is the primary means for manual pilot data entry for communications, navigation, and autopilot data. To solve this problem for EMD, the F-22 HUD has a rubber buffer strip on it that effectively shields the polycarbonate of the canopy when it flexes during a birdstrike from hitting the optical glass in the HUD and shattering. It does not present information in color, but the tactical symbol set is the same that is used on the F-22's head down displays (HDDs).ĭuring F-22 canopy birdstrike tests, it was found that the HUD combiner glass would shatter the canopy. The F-22's HUD is approximately 4.5 inches tall and uses standardized symbology developed by the Air Force Instrument Flight Center. The GEC-built Head-Up Display (HUD) offers a wide field of view (30 degrees horizontally by 25 degrees vertically) and serves as a primary flight instrument for the pilot. The airplane can be ready to taxi in less than 30 seconds after engine start. All of this happens automatically with no pilot actions other than the three steps. Then the necessary navigation information is loaded and even the pilot's personal preferences for avionics configuration is read and the systems are tailored to those preferences. All subsystems and avionics are brought on line and built-in testing checks are made. There are only three steps to take the F-22 from cold metal and composites to full-up airplane ready for takeoff: The pilot places the battery switch 'on,' places the auxiliary power unit switch momentarily to 'start' and then places both throttles in 'idle.' The engines start sequentially right to left and the auxiliary power unit then shuts down. The idea is to relieve pilots of the bulk of system manipulations associated with flying and allow them to do what a human does best - be a tactician.Īircraft startup and taxi are excellent examples of harnessing the power of the computer to eliminate workload. Using the power of the onboard computers, coupled with the extensive maintenance diagnostics built into the F-22 by the maintainers, that workload has been significantly reduced. The F-22 cockpit lets the pilot do what humans do best, and it fully utilizes the power of the computer to do what it does best. Humans are good differentiators, but they are poor integrators. The F-22's cockpit represents a revolution over current "pilot offices", as it is designed to let the pilot operate as a tactician, not a sensor operator. While functionality is critical, the F-22's cockpit design also ensures pilot safety with an improved version of the proven ACES II ejection seat and a new pilot personal equipment and life support ensemble. The canopy is the largest piece of polycarbonate formed in the world with the largest Zone 1 (highest quality) optics for compatibility with helmet-mounted systems. It is the first baseline "night vision goggle" compatible cockpit, and it has designed-in growth capability for helmet-mounted systems. It accommodates the largest range of pilots (the central 99 percent of the Air Force pilot population) of any tactical aircraft. The F-22's cockpit is one of the very first "all-glass" cockpits for tactical fighters - there are no traditional round dial, standby or dedicated gauges.
