Abstract

A method of simulating a real-time aircraft system input to an avionics component for an aircraft includes receiving the simulation input and providing the simulated input to the avionics component.

Claims

1. A method of simulating a real-time, aircraft system input to an avionics component for an aircraft, the method comprising:

receiving a user demand for a real-time, aircraft system input;

retrieving data streams corresponding to the user demand from a data-base of previously recorded, real-time data streams;

time-synchronizing the retrieved data streams; and

providing the time-synchronized data streams as input to the avionics component.

2. The method of claim 1 wherein the user demand comprises a playback rate and the providing of the time-synchronized data streams is provided at the playback rate.

3. The method of claim 2 wherein the playback rate comprises at least one of real time, slower than real time, or faster than real time.

4. The method of claim 3 wherein the playback rate comprises a time step.

5. The method of claim 4 wherein the time step is a constant time increment.

6. The method of claim 1 wherein the data streams comprise data streams representative of at least one of an inertial reference data, a global positioning system data, air data computer data, instrument landing system data, navigation data, distance measuring equipment data, or selectable control panel data.

7. The method of claim 1 wherein avionics component comprises at least one of a flight management system, control display unit, primary flight display, or navigation display.

8. The method of claim 1 wherein the providing further comprises providing the time-synchronized data streams by way of an ARINC 429 interface.

9. The method of claim 1 further comprising retrieving, from the data-base of previously recorded data streams, a recorded time index corresponding to the data streams.

10. The method of claim 9 further comprising time-synchronizing the retrieved data stream in accordance with the recorded time index.

11. The method of claim 10 wherein the time-synchronizing further comprises scheduling the providing of the time-synchronized data streams.

12. The method of claim 11 wherein the providing occurs in accordance with the schedule.

13. The method of claim 1 wherein the providing further comprises providing the time-synchronized data streams by way of an Ethernet interface.

14. The method of claim 1 wherein the providing further comprises providing the time-synchronized data streams by way of a serial interface.
