Engine Maintenance: The Pratt & Whitney F119 engines are designed to allow standard flight line maintenance using just six common tools available at commercial hardware stores. The F-22 has integrated radio functionality, the signal processing systems are virtualized rather than as a separate hardware module. [154] The integrated control panel (ICP) is a keypad system for entering communications, navigation, and autopilot data. Two 3in ×4in (7.6cm ×10.2cm) up-front displays located around the ICP are used to display integrated caution advisory/warning (ICAW) data, CNI data and also serve as the stand-by flight instrumentation group and fuel quantity indicator for redundancy. [155] The stand-by flight group displays an artificial horizon, for basic instrument meteorological conditions. The 8in ×8in (20cm ×20cm) primary multi-function display (PMFD) is located under the ICP, and is used for navigation and situation assessment. Three 6.25in ×6.25in (15.9cm ×15.9cm) secondary multi-function displays are located around the PMFD for tactical information and stores management. [156] Lloyd, Alex R. (26 January 2021).

Our strategic partnership with the U.S. Air Force helps to merge highly complex sustainment activities into one unified operation. This integration allows for greater efficiency, lower cost, and enhanced responsiveness to the needs of the operators and maintainers in the field. The aircraft has an integrated avionics system where through sensor fusion, data from all onboard sensor systems as well as off-board inputs are filtered and processed into a combined tactical picture, thus enhancing the pilot's situational awareness and reducing workload. Key mission systems include Sanders/General Electric AN/ALR-94 electronic warfare system, Martin Marietta AN/AAR-56 infrared and ultraviolet Missile Launch Detector (MLD), Westinghouse/ Texas Instruments AN/APG-77 active electronically scanned array (AESA) radar, TRW Communication/Navigation/Identification (CNI) suite, and long range advanced IRST currently being tested. [100] The F-22's baseline software has some 1.7million lines of code, the majority involving the mission systems such as processing radar data. [139] The integrated nature of the avionics, as well as the use of Ada, [N 11] has made the development and testing of upgrades challenging. To enable more rapid upgrades, the avionics suite added an open mission systems (OMS) processor, as well as an open-source Kubernetes platform called the Open Systems Enclave (OSE) to enable the use of containerized software from third-party vendors.

Reliability goes up above 70 percent for missions with lower stealth demands." [131]

Modernization Line: The Ogden Air Logistics Center at Hill Air Force Base houses the only current F-22 Modernization Line, integrating the latest system capabilities to enhance the Raptor’s asymmetric advantage over adversaries. The 43rd Fighter Squadron was reactivated in 2002 as the F-22 Formal Training Unit (FTU) for the type's basic course at Tyndall AFB. Following severe damage to the installation in the wake of Hurricane Michael in 2018, the squadron and its aircraft were relocated to nearby Eglin AFB; the storm had also damaged several F-22s, which were later repaired. [183] The FTU and its aircraft were reassigned to the 71st Fighter Squadron at Langley AFB in 2023. [184] To reduce operating costs and prolong the F-22's service life, some pilot training sorties are performed using flight simulators, while the T-38 Talon is used for adversary training. [168] The advanced F-22 weapons instructor course at USAF Weapons School is conducted by the 433rd Weapons Squadron at Nellis AFB.
