Abstract

A system and process for providing systematic, updated, weather information from the ground to the pilot of an aircraft are disclosed. A ground station receives and assimilates weather data for satellite broadcast as digital weather data that is received by an aircraft (while on the ground or while airborne) within the satellite coverage area, encoded by a flight processor, and shown on a display screen to the pilot in map-type depictions and alpha-numeric format tailored to the operational needs of the pilot. The flight processor provides near real-time automatic processing and comparison of surface weather observations with the applicable forecast in both text and map depictions. The display screen information is controlled by a control panel that permits the pilot to select the departure, destination, alternate and any arbitrary airport with this selection establishing the map boundaries and with the projected flight path marked thereon.

(f) display and control instrumentation for displaying said converted weather map and pictorial depictions, on command, to the pilot of the aircraft;

said display and control instrumentation including a flight display screen for displaying said specific weather map and pictorial depictions to the pilot of the aircraft and a control panel having a series of buttons and knobs to permit the pilot to select the information to be displayed on said display screen;

said control panel including a weather display section, a weather display rotary knob having a pointer thereon disposed on said weather display section, a plurality of fixed numerical indicia circumferentially disposed in spaced relationship about said weather display rotary knob, said weather display rotary knob being selectively movable by the pilot to position said pointer directed toward any one of multiple positions indicated by said numerical indicia, each one of said numerical indicia indicating at least one of multiple selections of weather map and pictorial depictions available for display on said flight display screen from specific weather data received by said receiver means and processed by said flight processor means.

2. The automated weather support system of claim 1 including a recall push button disposed on said weather display section of said control panel, said recall push button, when depressed once, remaining depressed and becoming illuminated while effecting replacement of the present display on said flight display screen with the last previous depiction shown on said flight display screen, and when said recall button is depressed a second time, effecting the display on said flight display screen to revert to its previous status while returning said recall push button to its normal and unlighted status.

3. The automated weather support system of claim 1 including a lighted screen window disposed above said weather display section of said control panel to visually indicate to the pilot the title of the weather information being displayed on said flight display screen.

4. The automated weather support system of claim 1 including a display modification section on said control panel, said display modification section having a display modification rotary knob provided with a pointer thereon, said display modification section modifying said weather display section and including a plurality of fixed numerical indicia circumferentially disposed in spaced relationship about said display modification rotary knob, said display modification rotary knob being selectively movable by the pilot to position said pointer directed toward any one of multiple positions as indicated by said numerical indicia, each of said indicia indicating one of multiple positions of said display modification rotary knob for effecting the display modification on said flight display screen of the weather information displayed in response to pilot action of said weather display section of said control panel.

5. The automated weather support system of claim 4 including a lighted screen window disposed above said display modification section, a legend push button provided between said display modification rotary knob and said lighted screen window disposed above said display modification section, said legend push button, when depressed once, becoming illuminated and remaining depressed while effecting display of the appropriate legend on said flight display screen for the display modification being shown, and said legend push button, when depressed a second time returns to the original position, is no longer illuminated, and the legend display on said flight display screen is removed, said lighted screen window disposed above said display modification section indicating the appropriate display modification being shown on said flight display screen depending upon the numbered position of said display modification rotary knob.

6. The automated weather support system of claim 1 including a station select section on said control panel, said station section including a station select rotary knob having a pointer thereon, fixed indicia disposed at ninety degree intervals about said station select knob, said fixed indicia representing (a) departure, (b) destination, (c) alternate, and (d) arbitrary airports, and said station select rotary knob being sequentially rotated between each of said indicia for the pilot to designate an airport for each representation.

7. The automated weather support system of claim 6 including,

a scroll lever provided on said station select section,

said scroll lever being selectively movable from a neutral center position to an up or down position,

a station display screen window disposed above said station select section of said control panel,

said scroll lever effecting movement of a stored alphabetical listing of airport identification letters on said station display screen window, and

an enter push button disposed between said station select rotary knob and said station display screen window, whereby

when said station select knob is pointed to the departure position and the airport identification letters for the departure airport appear on said station display screen window, movement of said scroll lever to the neutral position and depressing said enter push button enters the departure airport into said flight processor means, the pilot then rotates said station select knob to point to the destination position and the scroll lever actuated until the destination airport identification appears on said station display screen window where said scroll is again neutralized and the destination airport entered into said processor means by depressing said enter push button, the alternate and arbitrary airports are selected and the information entered into said flight processor means and all map depictions displayed thereafter on said flight display screen by said weather display and said display modification sections of said control panel will show a background map of the area surrounding the designated departure, destination and alternate airports with a solid black line being shown between the departure and destination airport and a dotted line disposed from the destination airport to the alternate airport.

8. The automated weather support system of claim 1 including at least one ground station processor unit for receiving the edited digital weather data blocks from said communications processor means and including at least one control and display unit, said ground station processor serving to convert the digital weather data blocks received into specific weather map and pictorial depictions for display by said at least one control and display unit for use in preflight planning by pilots.

9. An automated weather support system for automatically providing systematic, updated weather information from the ground to the pilot of an aircraft operating over the continental United States or other large area without requiring the pilot to request weather information from any communications facility or to identify the aircraft or its position to any air traffic control facility or other communication facility on the ground, comprising:
