Abstract

A directional gyro for aircraft having on its stationary face plate, color zones referable separately to portions of the 360° movable directional scale; each color zone indicating a particular entry procedure (direct, parallel, or tear drop) for the preselected radial.

Claims

1. A colored indication plate on a directional gyro for indicating holding pattern entry procedures comprising,

a. a directional gyro with, a movable calibrated directional scale on the gyro,

b. a stationary face plate on the gyro,

c. a plurality of distinctive areas arranged in segments of a circle on the stationary face plate of the gyro, each one of said segments referable to a controller assigned holding radial on the movable calibrated directional scale, whereby a pilot may read which approach entry pattern procedure to adopt from the identity of the distinctive segment opposite the assigned holding radial.

2. A colored indication plate on a directional gyro for indicating holding pattern entry procedures comprising:

a. the device according to claim 1 in which the plurality of distinctive areas are arranged in an outer circle and an inner circle, the one circle corresponding to a standard entry procedure, and the other circle corresponding to a non-standard entry procedure.

3. A colored indication plate on a directional gyro for indicating holding pattern entry procedures comprising:

a. the device according to claim 1 in which the distinctive areas in each circle have a particular coloration distinguishing one area from another.

4. A colored indication plate on a directional gyro for indicating holding pattern entry procedures comprising:

a. the device according to claim 1,

b. a first segment of the distinctive areas extending from 0°

to 70°

,

c. a second segment of the distinctive areas extending from 70°

to 290°

,

d. a third segment of the distinctive areas extending from 290°

to 360°

,

e. the distinctive areas defining a standard holding pattern entry.

5. A colored indication plate on a directional gyro for indicating holding pattern entry procedures comprising:

a. the device according to claim 4,

b. the first, second and third segments each having coloration distinguishing each from the others.

6. A colored indication plate on a directional gyro for indicating holding pattern entry procedures comprising:

a. the device according to claim 1,

b. a first segment of the distinctive areas extending from 0°

to 110°

,

c. a second segment of the distinctive areas extending from 110°

to 290°

,

d. a third segment of the distinctive areas extending from 290°

to 360°

,

e. the distinctive areas defining a non-standard holding pattern entry.

7. A colored indication plate on a directional gyro for indicating holding pattern entry procedures comprising:

a. the device according to claim 6,

b. the first, second and third segments each having coloration distinguishing each from the others.

8. A colored indication plate on a directional gyro for indicating holding pattern entry procedures comprising:

a. the device according to claim 1 and,

b. separate displays depicting holding pattern entry procedures by flight patterns,

c. the holding pattern entry procedures in the separate displays depicting tear drop, direct, and parallel entry procedures,

d. each entry procedure flight path depicted distinctively and corresponding with a particular distinctive area on the stationary face plate.

9. A colored indication plate on a directional gyro for indicating holding pattern entry procedures comprising:

a. the device according to claim 1, and

b. the distinctive areas being marked respectively direct, parallel and tear drop.
