Abstract
Wind direction relative to an aircraft, wind speed and left/right wind correction angle data are derived and serially transmitted to an instrument panel indicator which simultaneously displays such data in a graphic visual format. A simple 2-wire interface provides both power and data to the indicator which includes on-board data processing/display driver capability on one side of a PCB with the driven display elements on the other side of the PCB. The entire integrated driver display unit can be made quite small and adhesively mounted in virtually any desired location (e.g., even on a portion of another instrument face) and connected to the power/data source via an almost transparent 2-conductor umbilical connection.
Claims51
An aircraft wind indicator comprising:
- a printed circuit board having first and second surfaces, said first surface being opposed to said second surface;
- wind data display elements disposed on said first surface of said printed circuit board;
- and
- wind data processing and display driving circuits disposed on said second surface of said printed circuit board.
An aircraft wind indicator for use on an aircraft, said aircraft wind indicator comprising:
- visible digital display elements disposed to display wind speed and wind direction, said visible digital display elements being arranged to form an arcuate bar coded display;
- and
- digital data processing and indicator driving circuits connected to drive said visible digital display elements in accordance with digital data representing wind speed and wind direction when the aircraft is in flight.
An aircraft wind indicator for use on an aircraft, said aircraft wind indicator comprising:
- visible digital display elements disposed to display wind speed and wind direction, said visible digital display elements being arranged to form an arcuate bar coded display;
- and
- digital data processing and indicator driving circuits connected to drive said visible digital display elements in accordance with digital data representing wind speed and wind direction when the aircraft is in flight;
- wherein said visible digital display elements are also disposed to display a wind correction angle and said digital data processing and indicator driving circuits are also connected to drive said visible digital display elements in accordance with digital data representing a wind correction angle when the aircraft is in flight.
An aircraft wind indicator comprising:
- a housing containing a plurality of digital display elements and driving circuits therefor disposed for selective activation of said elements to represent the speed and direction of wind with respect to a moving airborne aircraft.
An aircraft wind indicator for use on an aircraft, said aircraft wind indicator comprising:
- a data input port,
- a first array of controllable discrete display elements arranged to graphically depict wind direction data;
- a second array of controllable discrete display elements arranged to graphically depict wind speed data when the aircraft is airborne;
- a third array of controllable discrete display elements arranged to graphically depict wind correction angle data;
- and
- data processing and display element driving circuits connected between said data input port and said arrays.
A method for displaying wind data in the cockpit of an aircraft, said method comprising:
- generating digital wind data representing the direction and magnitude of wind, being encountered by the aircraft when the aircraft is airborne, and correction angle data;
- periodically sending said generated digital wind data to a visual indicator in the aircraft cockpit;
- and
- receiving and processing said digital data at the indicator with a micro-processor to drive plural arrays of display elements at the indicator which thereby simultaneously provide a visual depiction of said wind data.
An aircraft wind indicator for use on an aircraft, said aircraft wind indicator comprising:
- visible display elements disposed to display a wind correction angle;
- and
- data processing and indicator driving circuits connected to drive said visible display elements in accordance with data representing a wind correction angle when the aircraft is in flight.
