The N57 engines are generally reliable and solid units, as long as you follow the manufacturer's service schedules, and use a good quality oil to ensure longevity. Few problems should happen as long as they are regularly serviced and maintained. The N57 is a turbocharged straight six and delivers power like a large V8 NASP in a steady linear manner.Butowski, Piotr (October 2019). "The Final Flanker; Russian Fifth-Gen". Air International.

Weak spots Issues & problem areas on the N57 For air-to-air combat, the Su-57 carries four beyond-visual-range missiles in its two main weapons bays and two short-range missiles in the side bays. [111] The primary medium-range missile is the active radar-homing R-77M ( izdeliye 180), an upgraded R-77 variant with AESA seeker, dual-pulse motor, and conventional rear fins. [112] The short-range missile is the infrared-homing ("heat seeking") R-74M2 ( izdeliye 760), an upgraded R-74 variant with reduced cross-section for internal carriage. [110] [113] A clean-sheet design short-range missile designated K-MD ( izdeliye 300) is being developed to eventually replace the R-74M2. [109] For longer ranged applications, the izdeliye 810 missile, a further development of the R-37M, can be carried with two in each main weapons bay. [ failed verification] [114] The Su-57 tests consisted of preliminary trials PI (Russian: ПИ, short for: Предварительные испытания) conducted by Sukhoi at the Gromov Flight Research Institute (LII, Russian: ЛИИ) at Zhukovsky, as well as two stages of joint state trials GSI (Russian: ГСИ, short for: Государственные совместные испытания) conducted by the Ministry of Defence at the 929th State Flight Test Centre (GLITs, Russian: ГЛИЦ) at Akhtubinsk. [146] The completion of GSI-1 resulted in the acceptance of the aircraft's airworthiness, and the completion of GSI-2, which tests the mission systems and armaments, clears the Su-57 for operational service. The preliminary trials and state trials occurred with some overlap with each other. [147]

One of the main technical goals of the PAK FA programme is to achieve total integration of avionics systems, or sensor fusion, increase the pilot's situational awareness and reduce workload. Integration of the Su-57's onboard systems is controlled by an IUS (Russian: ИУС, short for: Информационно-управляющая система, lit.'Information Management System'), with its computer system developed by GRPZ from Ryazan. The main avionics systems are the Sh-121 (Russian: Ш-121) multifunctional integrated radio electronic system (MIRES) and the 101KS "Atoll" (Russian: 101КС "Атолл") electro-optical system. [127] In a departure from prior Sukhoi aircraft, the IUS systems integration was performed by Sukhoi itself rather than RPKB of Ramenskoye. The integrated avionics suite, called IMA BK (Russian: ИМА БК, short for: Интегрированной модульной авионики боевых комплексов, lit.'Integrated Modular Avionics Combat Systems'), uses fibre optic channels and runs on over 4 million lines of code.

The CP3 seems to be better able to cope when remapped but will usually top out around 350hp. Flywheel lightening - a lower weight flywheel will improve the engines rev changes.

Sukhoi/HAL FGFA was a planned version of Su-57 for Indian Air Force but India withdrew from the FGFA programme in 2018 before any prototype was built. [198] The FGFA was intended to be the primary export version of the PAK FA and was to differ in 43 ways with improvements to stealth, supercruise, sensors, networking, and combat avionics. [225] [226] [227] There were conflicting reports on the FGFA, with India detailing numerous improvements over the baseline PAK FA, while Mikhail Pogosyan, the head of United Aircraft Corporation, said in 2013 that the PAK FA and the FGFA will use "identical onboard systems and avionics". [228] India has refrained from signing a deal with Russia citing concerns of aircraft's stealth, radar and supercruise capability in 2014 and ultimately withdrew from the programme in 2018.
