Onboard equipment data synchronization system
An onboard system in an aircraft records data simultaneously from a plurality of onboard products, systems, and devices. The data is recorded in response to an event trigger common to each onboard product, system, and device, and tagged with a common timestamp and stored in a centralized data store. The system compiles the data into a single dataset, synchronizing the data according to the common timestamp. The data may be modified to reflect the common timestamp where the data includes a different timecode from the original source. The data may also be modified to conform to a standard format. The dataset may be encrypted according to a standard and transmitted offboard for later analysis, or analyzed onboard if immediate analysis is required.
1. A computer apparatus comprising:
at least one processor in data communication with a data storage element and a memory storing processor executable code for configuring the at least one processor to:
receive an event trigger;
receive time synchronized equipment status records from each of a plurality of devices in data communication with the at least one processor;
compile all of the time synchronized equipment status records into one or more databases; and
transmit the single database to an offboard receiver.
2. The computer apparatus of claim 1 , wherein the event trigger comprises one or more aircraft level events including one or more of “weight-off-wheels”, “weight-on-wheels”, “power on”, “power off”, or “engine start-up”.
3. The computer apparatus of claim 1 , wherein the event trigger comprises a logical combination of a plurality of aircraft level events.
4. The computer apparatus of claim 1 , wherein the event trigger comprises a time periodic event.
5. The computer apparatus of claim 4 , wherein the at least one processor is further configured to alter a periodicity of the time periodic event.
6. The computer apparatus of claim 4 , wherein the at least one processor is further configured to switch between distinct sets of event triggers.

compile all of the time synchronized equipment status records into one or more databases; and
transmit the single database to an offboard receiver via the wireless communication element.
16. The aircraft system of claim 15 , wherein the event trigger comprises one or more aircraft level events including one or more of “weight-off-wheels”, “weight-on-wheels”, “power on”, “power off”, or “engine start-up”.
17. The aircraft system of claim 15 , wherein the event trigger comprises a logical combination of exceedances.
