| -------- | ---------------------- | ------ |
| 1-4      | Identification         | ✅     |

| 19       | Airborne Velocities    | ❌     |
| 20-22    | Airborne Position GNSS | ❌     |
| 28       | Aircraft Status        | ❌     |
| 29       | Target State & Status  | ❌     |

```
{
  ca: 5,
  data: {

  },
  df: 17,
  icao: '4840D6',
