Abstract
Abstract An aircraft navigation display which allows a pilot to easily envision his position, heading, wind drift and direction of travel relative to one or more radio stations. The presentation allows the pilot to quickly and easily understand and interpret the various indicia because the display is similar to a map and shows the aircraft's plan position and allows the pilot to fly holding patterns as well as cross country patterns since the position of the aircraft is continuously observable.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
142 words
A navigation instrument comprising a fixed compass rose; one more more VOR radio station symbols mounted rotatably around the perimeter of said compass rose with each such station symbol having a line corresponding to a radial from such station symbol that would correspond with a map showing and extending across the face of the instrument through the center and to the perimeter of said compass rose opposite the station symbol, each such symbol being slaved to a radio receiver and rotatable automatically by the radio mechanism to the point on the compass rose indicating the direction to the station; an airplane symbol rotatably mounted in the center of the face of said instrument and connected to a compass mechanism so that the direction of the aircraft is indicated by the nose of the symbol pointing to that direction on the compass rose.
Claim 2
Dependent Claim
142 words
A navigation instrument comprising a fixed compass rose; one more more VOR radio station symbols mounted rotatably around the perimeter of said compass rose with each such station symbol having a line corresponding to a radial from such station symbol that would correspond with a map showing and extending across the face of the instrument through the center and to the perimeter of said compass rose opposite the station symbol, each such symbol being slaved to a radio receiver and rotatable automatically by the radio mechanism to the point on the compass rose indicating the direction to the station; an airplane symbol rotatably mounted in the center of the face of said instrument and connected to a compass mechanism so that the direction of the aircraft is indicated by the nose of the symbol pointing to that direction on the compass rose.
Claim 3
Dependent Claim
144 words
An aircraft navigation instrument comprising a housing, a fixed compass rose mounted in said housing such that it is visible, an aircraft indicia mounted at the center of said compass rose and rotatable relative thereto, a compass means coupled to said aircraft indicia to drive it, a first radio indicia rotatably mounted to rotate relative to the center of the compass rose to indicate the direction to and from a first VOR radio station and said aircraft as shwown on a map, a first VOR radio receiver connected to drive said first radio indicia, including a second radio indicia rotatably mounted to rotate relative to the center of the compass rose to indicate the direction to and from a second VOR radio station and said aircraft as shown on a map, and a second VOR radio receiver connected to drive said second radio indicia.
Claim 4
Dependent Claim
144 words
An aircraft navigation instrument comprising a housing, a fixed compass rose mounted in said housing such that it is visible, an aircraft indicia mounted at the center of said compass rose and rotatable relative thereto, a compass means coupled to said aircraft indicia to drive it, a first radio indicia rotatably mounted to rotate relative to the center of the compass rose to indicate the direction to and from a first VOR radio station and said aircraft as shwown on a map, a first VOR radio receiver connected to drive said first radio indicia, including a second radio indicia rotatably mounted to rotate relative to the center of the compass rose to indicate the direction to and from a second VOR radio station and said aircraft as shown on a map, and a second VOR radio receiver connected to drive said second radio indicia.
Claim 5
Dependent Claim
21 words
An aircraft navigation instrument according to claim 2 including a wind indicia movable about said compass rose to indicate wind direction.
Claim 6
Dependent Claim
19 words
An aircraft navigation instrument according to claim 3 including means associated with said wind indicia to indicate wind velocity.
Claim 7
Dependent Claim
19 words
An aircraft navigation instrument according to claim 2 including a first reference indicia movable relative to said compass rose.
Claim 8
Dependent Claim
20 words
An aircraft navigation instrument according to claim 5 wherein said first reference indicia can be moved to an inoperable position.
Claim 9
Dependent Claim
19 words
An aircraft navigation instrument according to claim 5 including a second reference indicia movable relative to said compass rose.
Claim 10
Dependent Claim
159 words
An aircraft navigation instrument comprising a housing, a fixed compass rose mounted in said housing such that it is visible, an aircraft indicia mounted at the center of said compass rose and rotatable relative thereto, a compass means coupled to said aircraft indicia to drive it, a first radio indicia rotatably mounted to rotate relative to the center of the compass rose to indicate the direction to and from a first radio station and said aircraft, a first radio receiver connected to drive said first radio indicia, including a second radio indicia rotatably mounted to rotate relative to the center of the compass rose to indicate the direction to and from a second radio station and said aircraft, a second radio receiver connected to drive said second radio indica, including a wind indicia movable about said compass rose to indicate wind direction, and wherein said wind indicia is pivotally mounted so it can be moved to an inoperative position.
Claim 11
Dependent Claim
159 words
An aircraft navigation instrument comprising a housing, a fixed compass rose mounted in said housing such that it is visible, an aircraft indicia mounted at the center of said compass rose and rotatable relative thereto, a compass means coupled to said aircraft indicia to drive it, a first radio indicia rotatably mounted to rotate relative to the center of the compass rose to indicate the direction to and from a first radio station and said aircraft, a first radio receiver connected to drive said first radio indicia, including a second radio indicia rotatably mounted to rotate relative to the center of the compass rose to indicate the direction to and from a second radio station and said aircraft, a second radio receiver connected to drive said second radio indica, including a wind indicia movable about said compass rose to indicate wind direction, and wherein said wind indicia is pivotally mounted so it can be moved to an inoperative position.
