Chief of Flight Operations during a NASA space mission. The flight director works with many other talented individuals at the Lyndon B. Johnson Space Center in Houston, Texas. This location is commonly known as simply 'Houston' by NASA workers and astronauts. The National Aeronautics and Space Administration (NASA), which was established in 1958, is the agency responsible for the public space program of the United States of America. ...

The single cue type of flightdirector indicator permits the utilization of a single indicating element that displays pitch and roll command motions that are realistically suggestive of the aircraft control required of the pilot in response to the visual commands.
Moreover, the flightdirector indicator of the type having a relatively heavy servomechanism or meter movement, which applies a relatively large torque about the roll axis, would have its response and accuracy adversely affected by the torque if it were not for the counterweights.
The pitch command signal from the flightdirector system energizes the pitch motor 30 through slip rings 48' and brushes 55' and causes the helical gear 40 to rotate which, in turn, causes the worm wheel 41 to rotate and arm 20 to be displaced in a substantially vertical direction through rotation of shaft 47.
The major components of a flightdirector system are the flightdirector indicator (FDI), a horizontal situation indicator (HSI), a mode selector and a flightdirector computer.
These CRTs electronically display flight information in much the same presentation as electro-mechanical instruments bur they also have the flexibility for selecting additional information to be added to the display and for altering the presentation.
PRIMARY FLIGHT DISPLAY (PFD): The typical PFD is a multicolor CRT or LCD display unit that presents a display of aircraft attitude and flight control system steering commands including VOR, localizer, TACAN, or RNAV deviation; and glideslope or preselected altitude deviation.
