Flight Management Computer (FMC)

The flight management computers can be found on most commercial & business aircraft

Flight management computers assists the pilot in navigation, flight planning & aircraft control

Provides real-time navigation information such as the programmed route, database waypoints & standard departure/arrival procedures

Navigation information combined with airplane position used to drive moving map displays

Calculates performance data and vertical profiles based on weight, cost index, cruise altitude and predicted winds

Provides lateral and vertical path guidance to the auto-flight system when engaged

Aircraft Position

- Inertial Reference System

- Global Positioning System

- Navaids (VOR/DME/ADF)

Flight Management Computer

- Navigation Database

- Performance Calculations

Auto-Flight System

- Auto-throttle

- Flight Directors

Electronic Flight Instrument System

- Attitude Indicator

- Heading Indicator

Engine Indicating & Crew Alerting System (EICAS)

EICAS is designed to provide integrated engine information and crew annunciations Displays high and low turbine RPM, exhaust pressure ratio, temperature, oil pressure

and fuel flow indications The crew alerting feature provides EICAS messages, flight deck lamp control and aural

alerts Typical systems monitored by EICAS include hydraulics, pneumatics, electrical, deicing,

environmental controls and flight controls surfaces High connectivity, provides data acquisition and routing

Modular Mission Computer (MMC)• General Avionics Computer/Fire Control Computer

• Head-Up Display Electronics Unit

• Central Interface Unit Stores Management Computer

• Uses 64-bit wide architecture with a 1245 hour mean time between failure

• 15 modules in the 24 slot chassis, 6 processor, 4 I/O, 5 Power Supplies, 9 Future Growth

• Employs digital data bus channesl to communicate with avionics systems

• Enhances situational awareness, air-to-air capabilities & targeting accuracies

• Enables use of helmet mounted cueing systems, advanced weapons loads, reconnaissance pods, forward looking infrared targeting & navigation systems

Navigation/Attack Computer

Allows military aircraft to locate and attack specific ground targets with a high degree of accuracy

Digital computing technology is used to integrate a wide variety of sensors to compile data and present it to the aircrew

Typical Navigation/Attack computers uses Inertial Reference Systems to locate the target without having to rely on active sensors such as radar which can be detected

Inertial positions periodically updated with GPS, VOR/DME/ADF or Doppler Radar

Provides lateral guidance commands to the auto-flight system if coupled Computes range to target and other parameters required for weapons delivery The crew authorizes a weapons release but the computer is responsible for

releasing the weapon compensating for wind, aircraft speed and other factors
