What does a flashing entry on the UFCP indicate?

• A. Invalid data entry
• B. Missing data entry
• C. System error
• D. Normal operation

Answer: (A)

The flashing entry on the UFCP is signaling that the data you entered cannot be accepted as written. It’s a visual cue for an invalid data entry—the system is telling you the value, format, or range is not allowed in the current context, and you need to correct it before continuing. Think of it like when a field requires a specific format (such as a frequency, coordinate, or altitude) and the value you typed doesn’t meet those rules. You’d re-enter it in the proper form or within the allowed range, and the flashing indicator would stop once the UFCP accepts the input. This is different from missing data, which would typically prompt a prompt or highlight that a required field hasn’t been filled, and from a system error, which would usually trigger a warning message or alarm across the cockpit. Normal operation shows steady, valid data entry without flashing.
