The following sections list all entities in the dialect (both included and defined in this file).
Composite EFI and Governor data from Loweheiser equipment. This message is created by the EFI unit based on its own data and data received from a governor attached to that EFI unit.
| Field Name | Type | Units | Description |
|---|---|---|---|
