Recorded demo calls
Real demo calls made to the Flight Service phone line, with the recording, transcript, stored weather briefing, flight details, summary and review findings wherever they exist. They are recorded calls, not synthetic requests, and are never counted together with them.
Kept up to date, and what that is not. New calls are read from the call archive and the voice platform on a schedule, checked, and published as a numbered release that is complete and never changed afterwards. Whether that is happening right now is stated in Updates and freshness, from what the updater last recorded. Phone numbers, e-mail addresses, links and street addresses are masked in text as far as the masking can find them, and the caller number and name the archive stores are left out of these records. That is not anonymisation. Names and numbers spoken on a call can still be heard in the unedited recording or read in a transcript, and voices and aircraft identifiers remain. The synthetic request lab on the other tabs is separate: it comes from a generator, and none of its figures describe these calls.

Trends across the recorded calls
Worked out from the calls in this release and nothing else. Shares are shown because there are at least 30 calls. Length is how long the call lasted. It is not how fast the service answered, which these calls do not record.

What the checks found
Local checks of what was recorded, not a judgement. Each check reads recorded text or fields (what was said, what a tool returned, whether a recording or a review finding exists). None listens to a recording and none uses a model. A check says "passed" only when the record shows it, "flagged" only when the record shows the problem, and otherwise "unknown": a call is never counted as fine because nothing failed. Version 1 of the checks. The items these raise are also listed, apart from the synthetic ones, on the Improvement queue.
| Check | Flagged | Passed | Unknown | Share of the calls it could decide | Latest flagged |
|---|---|---|---|---|---|
| The notice that this is not an official briefing was said by the agent Flagged means: The agent spoke but did not give the notice | 3 | 31 | 24 | 8.8% of 34 | call · call · call |
| The weather lookup returned a result Flagged means: The weather lookup returned an error | 1 | 15 | 42 | 1 of 16 (a share is shown from 30 calls) | call |
| A weather briefing was stored for the call Flagged means: The pilot was told the briefing was unavailable | 0 | 16 | 42 | 0 of 16 (a share is shown from 30 calls) | none |
| The archive's automatic checks Flagged means: An automatic check failed | 5 | 29 | 24 | 14.7% of 34 | call · call · call |
