This standard sets forth the characteristics of a FCCS within an Automatic Flight System. The FCCS is intended to provide autoland capability for commercial aircraft. The document provides design guidance for the development and installation of a FCCS.

The FMCS provides performance data, performance computations, fuel management functions, and navigation and guidance to a desired flight plan.

It is intended to process caution and warning inputs for visual and/or audible presentation to the flight crew.

This document presents standard methods to evaluate the common mode and differential mode insertion loss of passive electromagnetic interference power line filters from 10 kHz through 10 GHz. Insertion loss test methods for both quality assurance and performance prediction purposes are described. ...The performance prediction tests are selected to more closely approximate operating impedances. They are not intended to be inclusive or to represent worst case conditions.

Computer-controlled thermostats enabled setpoint flexibility; adjustments to setpoints were made after solar thermal vacuum testing and during flight. This paper covers the design, thermal testing and flight experiences with the computer-controlled thermostats on the propulsion line heaters. ...The MER cruise stage thermal design employed a computer-controlled thermostatic heater system to keep the propellant lines within their allowable flight temperature limits (17°C to 50°C). The MER propellant line thermal design differed from previous propellant line heater designs in that the line heaters were placed only in areas of highest potential heat loss (not along the entire length of the lines) and that computer-controlled thermostats were used instead of mechanical thermostats. ...The MER propellant line thermal design differed from previous propellant line heater designs in that the line heaters were placed only in areas of highest potential heat loss (not along the entire length of the lines) and that computer-controlled thermostats were used instead of mechanical thermostats.
