Abstract

A standby instrument, such as a standby attitude indicator, including a display, an attitude sensor module, and a speech synthesizer connected to the attitude sensor module. The standby instrument is controllable to cause the speech synthesizer to audibly speak attitude information generated by the attitude sensor module, thereby providing attitude information to a pilot even when a view of the standby instrument is impaired by, e.g., smoke.

Claims

1. A standby instrument, comprising:

a display;

an attitude sensor module; and

a speech synthesizer connected to the attitude sensor module,

wherein the speech synthesizer is operable to audibly speak at least a portion of attitude information generated by the attitude sensor module.

2. The standby instrument of claim 1, further comprising at least one speaker.

3. The standby instrument of claim 2, wherein an output of the speech synthesizer is activated by a switch associated with the at least one speaker.

4. The standby instrument of claim 1, wherein the display comprises a touch screen display.

5. The standby instrument of claim 1, wherein the volume of synthesized speech is controllable.

6. The standby instrument of claim 5, wherein the volume is controllable via the display.

7. The standby instrument of claim 1, further comprising a slip ball.

8. The standby instrument of claim 1, further comprising a battery.

9. The standby instrument of claim 1, wherein the standby attitude indicator is programmable to audibly speak pre-selected information generated by the attitude sensor module.

10. An emergency avionics instrument, comprising:

an attitude module; and

a speech synthesizer, the speech synthesizer operable to annunciate at least a portion of attitude information generated by the attitude module, wherein the activation and volume of the speech synthesizer are controllable.

11. The instrument of claim 10, further comprising a display that displays the attitude information generated by the attitude module.

12. The instrument of claim 11, wherein the display comprises a touch sensitive display.

13. The instrument of claim 10, further comprising at least one speaker.

14. The instrument of claim 13, wherein a switch associated with the at least one speaker controls the activation of the speech synthesizer.

15. The instrument of claim 10, further comprising a battery.

16. An emergency avionics system, comprising:

a standby instrument;

a speech synthesizer in electrical communication with the standby instrument; and

a speaker, connected to but not integral with the standby instrument, the speaker being driven by the speech synthesizer,

wherein the speech synthesizer is operable to annunciate at least a portion of information generated by the standby instrument.

17. The system of claim 16, wherein activation of the speech synthesizer is initiated by at least one of the standby instrument and the speaker.

18. The system of claim 16, wherein the information that is annunciated is preprogrammable.

19. The system of claim 16, wherein the volume of annunciation is controllable.

20. The system of claim 16, wherein at least pitch and roll information is annunciated.

21. The system of claim 16, wherein the speech synthesizer is powered by a battery associated with the standby attitude indicator.
