BUCS | |||
---|---|---|---|
(AH-64D Apache) Back-Up Control System Normally, the pilot and CPG flight controls are mechanically linked. The mechanical linkages are protected by shear pins and mis-track sensors to prevent a control jam or severance from affecting both sets of flight controls. If the flight controls are decoupled by the shear pin, or a mis-track is otherwise sensed, the Back-Up Control System is automatically activated. The BUCS is a single-channel, four-axis, non-redundant electric fly-by-wire (FBW) system. The FBW system is designed to replicate the feel of the hydromechanical controls but does not replicate SCAS functionality. BUCS can only be active for the pilot or the CPG station. Either the pilot or the CPG can transfer BUCS control to their station if necessary, depending on the nature and location of the jam or severance within the flight controls. | |||
CMS | |||
---|---|---|---|
(A-10C Warthog) Counter Measures Set The A-10C has a defensive system that helps alert and protect you against enemy weapon systems with radar and laser illumination. This includes support for Electronic Counter Measure (ECM) pods, chaff and flare dispensers, a radar warning receiver set, and a Missile Warning System (MWS). These systems are combined to form the CounterMeasures Set (CMS). The CMS has two primary panels: the Countermeasures Signal Processor (CMSP) panel and the Countermeasures Set Control (CMSC) panel. | |||
ECS | |||
---|---|---|---|
(AH-64D Apache) Environmental Control System The ECS provides crewmember comfort through ventilation, heating, and air conditioning. Ventilation is provided by pilot and CPG gaspers, which can be opened to admit outside air into the cockpit. The ECS also powers ventilation fans that provide forced air exchange between the cockpits and for avionics cooling. | |||
ECU | |||
---|---|---|---|
(AH-64D Apache) Electronic Control Unit Detects overspeed and overcurrent anomalies, as well as abnormal oil pressure. The ECU will automatically shut down the APU when an anomaly is detected. The ECU also controls the power takeoff (PTO) clutch engagement to the accessory section of the main transmission. | |||
EPMS | |||
---|---|---|---|
(AH-64D Apache) Electrical Power Management System Electrical aircraft power is managed by the EPMS. The EPMS is a fully redundant and automatic power system consisting of a distributor for battery, AC, and DC power. | |||
FMC | |||
---|---|---|---|
(AH-64D Apache) Flight Management Computer The FMC provides rate damping to smooth flight control inputs and command augmentation. It also provides limited attitude and altitude hold capability for hands-off flying. | |||
GCU | |||
---|---|---|---|
(AH-64D Apache) Generator Control Unit AC power is provided by two brushless, air-cooled generators. Each generator outputs 45 kVA three-phase four-wire power at 115 or 200 volts and 400 Hz. Each generator has its own Generator Control Unit. A single generator is capable of handling full flight loads without shedding. The generators are mounted to the transmission accessory gearbox. | |||
IPAS | |||
---|---|---|---|
(AH-64D Apache) Integrated Pressurized Air System The IPAS provides pressurized air to aircraft pneumatic systems. Bleed air is drawn from two ports: a high-pressure port is exclusively used to pressurize the hydraulic systems, and a low-pressure port is used by all other consumers. Low-pressure air is used by the engine air turbine starters, fuel boost and transfer pumps, anti-ice system, ice detection probe, nitrogen inerting unit, vapor cycle cooling system, and environmental control system. IPAS bleed air can be provided by one or both engines, the APU, or an external source such as an AGPU. | |||
LBHMMS | |||
---|---|---|---|
(AH-64D Apache) Longbow Hellfire Modular Missile System The LBHMMS provides precision fire capability against point targets at long range. The AGM-114K “Kilo” and AGM-114L “Lima” Hellfires were designed as modern-day tank killers, able to defeat any known armor on the battlefield. | |||
M-TADS | |||
---|---|---|---|
(AH-64D Apache) Modernized Target Acquisition Designation Sight The M-TADS is a long-range, precision engagement and pilotage solution for day, night, and adverse weather missions. | |||
NIU | |||
---|---|---|---|
(AH-64D Apache) Nitrogen Inerting Unit The fuel cells are inerted using nitrogen to reduce the risk of fire. The NIU is completely self-contained and automatic. It uses aircraft power and pressurized air and generates an inerted mix containing around 99% nitrogen. This inerted gas is used to pressurize the internal cells. It is also routed to the IAFS during fuel transfer. | |||
SCAS | |||
---|---|---|---|
(AH-64D Apache) Stability and Control Augmentation System Hydraulic augmentation, which consists of hydraulic actuators controlled by the FMC. The command augmentation system provides consistent control feel across the full range of helicopter airspeeds. The SCAS also provides automatic turn coordination for turns above 40 knots airspeed. | |||
TADS | |||
---|---|---|---|
(AH-64D Apache) Target Acquisition Designation Sight The AH-64A was equipped with a revolutionary new targeting system (TADS). It was designed to allow aircrews to acquire targets and steer the 30mm cannon using a helmet-mounted sight. | |||
TRU | |||
---|---|---|---|
(AH-64D Apache) Transformer-Rectifier Unit DC power is provided by two Transformer-Rectifier Units (TRUs), each providing 28 volts and 350 amps of DC power. Like the generators, a single TRU can provide sufficient power for full flight loads without shedding. | |||
9-line | ||||
---|---|---|---|---|
Ein FAC (bzw. JTAC) teilt einem Piloten beim einem CAS-Einsatz mit, wann, wo und mit welcher Waffe angegriffen werden soll. Die Stellung befreundeter Einheiten, An- und Abflug, Zielposition und -beschreibung usw. muss in kurzer Zeit effektiv und möglichst unmissverständlich kommuniziert werden. Dafür wurde ein Standard-Verfahren eingeführt, welches als 9-Line bezeichnet wird, weil die Informationen in neuen Zeilen übergeben werden. Weitere Informationen: | ||||

ABRIS | ||||
---|---|---|---|---|
The ABRIS is one of the two navigation systems of the KA-50. It uses a graphical display and is also known as the Advanced Moving Map System. It operates independently of the PVI-800 with the exception of the graphical representation of a PVI-800 navigation target in the ABRIS as a blue square. The basis of the ABRIS positioning is the Russian satellite navigation system, GLONASS. The ABRIS can be used to plan the flight route as well as to display target information from other KA-50 by means of a data link. The viewing direction and the distance in which the Shkval points are also displayed. Further Information: KA-50 Black Shark Basic Course (DCS) / Cockpit Briefing / Cockpit Overview / FP
