PIREP Compliance — FAA JO 7110.65

Facility setup

Facility airport ID

Use the 4-letter ICAO id, not the 3-letter identifier — KCVG, not CVG. Contiguous US adds a leading K; Alaska starts PA, Hawaii PH. Drives both data pulls: METARs (36 h) and PIREPs within 50 NM (36 h) from aviationweather.gov.

PIREP station prefix

A PIREP is credited to this facility only when its raw text begins with this prefix (auto-derived from the airport ID; edit if your feed differs).

Altitude ceiling (FL)

Used two ways: (1) PIREPs above this flight level are excluded from PIREP-found matching — they're outside your airspace. (2) G-AIRMET/SIGMET/CWA hazards based above this altitude are excluded from the Forecast Trigger column, since they don't overlap airspace you own. Default: FL200. A tower/TRACON that owns airspace only up to, say, 13,000 ft should set this to 130.

METAR hour filter — midnight-shift traffic exclusion (Zulu) all 24 hours evaluated

Some facilities have no traffic during certain midnight-shift hours. The METARs still publish and may show PIREP-required conditions, but with no aircraft airborne a PIREP is impossible — those hours would unfairly flag Non-Compliant. Tap an hour to exclude it from evaluation. Default: all 24 hours evaluated.

Each refresh logs today's compliance for this facility (stored in this browser). One entry per day — refreshing again overwrites today's row.

Solicitation triggers per FAA JO 7110.65 para 2-6-2: ceilings at or below 5,000 ft (approach control must obtain at least one descent/climb-out PIREP each hour), visibility at or below 5 SM, thunderstorms present or forecast, moderate+ turbulence, light+ icing, wind shear, braking action less than good. Hour keys and observation times are Zulu. Routine METARs at :50–:59 are credited to the following hour; when two :50+ observations map to the same hour, the one closest to the top of the hour is evaluated and the older one is rolled up (not double-counted). Archive data is stored locally in this browser per facility.
