FLIGHT MANAGEMENT CHAPTER 11
NAVIGATION SYSTEMS DESCRIPTION
Task: 1) analyze the following manuals and describe the structure and the content of this document; 2) prepare glossary for each paragraph; 3) find additional materials about modern aircraft for discussion (glossary, structure, arrangement).
Operations Manual
Introduction
Navigation systems include the flight management system (FMS); global positioning system (GPS); inertial reference system (IRS); radio navigation systems (ADF, DME, ILS, marker beacons, and VOR); transponder; and weather radar.
Flight Management System
The flight management system (FMS) is comprised of the following components:
• flight management computer system (FMCS)
• autopilot/flight director system (AFDS)
• autothrottle (A/T)
• global positioning system (GPS)
• inertial reference systems (IRS).
Each of these components is an independent system, and each can be used independently or in various combinations. The term FMS refers to the concept of joining these independent components together into one integrated system which provides continuous automatic navigation, guidance, and performance management.
The integrated FMS provides centralized flight deck control of the airplane's flight path and performance parameters. The flight management computer, or FMC, is the heart of the system, performing navigational and performance computations and providing control and guidance commands.
The primary flight deck controls arc the AFDS MCP, two control display units (CDUs), and two electronic flight instrument system (EFIS) control panels. The primary displays arc the CDUs, electronic attitude director indicator (EADI), electronic horizontal situation indicator (EHSI), and thrust mode display.
The FMC uses crew entered flight plan information, airplane systems data, and data from the FMC navigation database and performance database to calculate airplane present position, and pitch, roll, and thrust commands required to fly an optimum night profile. The FMC sends these commands to the autothrottle, autopilot, and night director. Map and route information arc sent to the respective pilot's EHSI. The EFIS control panels arc used to select the desired information for navigation display. The mode control panel is used to select the autothrottle, autopilot, and night director operating modes.
