An integrated primary flight display apparatus for an aircraft provides coordinated information with minimum eye scan distances. Various cathode ray tube generated presentations are centered toward a common electronic attitude director indicator having indicia thereadjacent and pointers centrally directed. A moving altitude scale is utilized with a fixed vertical speed scale employed to select the correct vertical speed for leveling off at a given altitude. An arcuate shaped heading indication is expanded in angular extent to achieve enhanced sensitivity.

A primary flight display for an aircraft, comprising: means defining a display field including a central attitude director indicator, a vertically disposed, movable altitude scale on a first side of said central attitude director indicator, including a relatively fixed pointer provided with a window for digital display, and means responsive to the altitude of said aircraft for moving said scale relative to said pointer and generating said digital display indicating the altitude of said aircraft, wherein said scale is adjacent said central attitude director indicator and said pointer points toward said scale and said attitude director indicator, a vertically disposed, movable air speed scale on a second side of said central attitude display indicator opposite said first side, including a second relatively fixed pointer provided with a second window for digital display, and means responsive to the air speed of said aircraft for moving said air speed scale relative to said second pointer and generating said digital display for said second window indicating the air speed of said aircraft, wherein said air speed scale is adjacent said central attitude director indicator and said second pointer points toward said air speed scale and said attitude director indicator, a movable, arcuate heading scale adjacent and below said attitude director indicator, including a third relatively fixed pointer provided with a third window for digital display, and means responsive to the heading of said aircraft for moving said heading scale relative to said third pointer and generating said digital display for said third window indicating the heading of said aircraft, wherein said heading scale is adjacent said central attitude director indicator and said third pointer points toward said heading scale and said attitude director indicator, and a relatively fixed vertical speed scale on said first side of said central attitude display indicator adjacent said altitude scale and on the remote side of said altitude scale from said central attitude director indicator, including a fourth relatively movable pointer directed radially toward both said vertical speed scale and said altitude scale from an apparent origin on the remote side of said vertical speed scale from said altitude scale such that said fourth pointer changes radial direction as it moves along said vertical speed scale, and means responsive to the vertical speed of said aircraft for moving said fourth pointer along said vertical speed scale, wherein graduations along said vertical speed scale and said altitude scale are such that said fourth pointer simultaneously points toward a selected altitude and the vertical speed appropriate for attaining the selected altitude.
