has a glass cockpit with no analogue gauges; information is displayed on two main multi-functional LCD displays similar to the arrangement of the Su-35S. Supplementing the primary display is a smaller multi-functional display and digital control panel. The cockpit has a wide-angle (30° by 22°) head-up display (HUD). Primary controls are the joystick and a pair of throttles, with all major functions controlled with hands on throttle and stick (HOTAS). The aircraft uses a two-piece canopy, with the aft section sliding forward and locking into place. The canopy is treated with metallized coatings to reduce the aircraft's radar signature. The aircraft uses the NPP Zvezda K-36D-5 ejection seat and the SOZhE-50 life support system, which comprises the anti-g and oxygen generating system. The pilot is equipped with ZSh-10B helmet which mounts the NSTsI-50 digital display system, which enhances pilot situational awareness through pupil tracking and allows engagement of targets at high angles off-boresight. The oxygen generating system provides the pilot with unlimited oxygen supply. The life support system enables pilots to perform 9-g maneuvers for up to 30 seconds at a time, while the ejection seat and the new PPK-7 flight suit allows safe ejection at altitudes from 0 to and instrument airspeeds from 0 to ; the system also includes a survival kit to assist the pilot after ejection. Avionics 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 (, ), with its computer system developed by GRPZ from Ryazan. The main avionics systems are the Sh-121 () multifunctional integrated radio electronic system (MIRES) and the 101KS "Atoll" () electro-optical system. 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 (, ), uses fibre optic channels and runs on over 4 million lines of code. The Sh-121 consists of the N036 Byelka radar system and L402 Himalayas electronic countermeasures (ECM) system. Developed by Tikhomirov NIIP Institute, the N036 consists of the main nose-mounted N036-1-01 X band active electronically scanned array (AESA) radar, or in Russian nomenclature, active phased array radar (, ), with 1,514 T/R modules and two side-looking N036B-1-01 X-band AESA radars with 404 T/R modules embedded
