Flight planning: Chino Airport CNO / KCNO

What a pilot looks at before a flight from or to Chino Airport in Chino, California, in plain English: right now VFR: good flying weather, Wind from the west-southwest (240°) at 10 knots. The warnings, reports and winds below come from the government's aviation weather service and the restrictions from the FAA, refreshed every few minutes. For planning, not a briefing: the legal preflight briefing comes from Flight Service (1-800-WX-BRIEF) or the FAA's own tools.

Warnings in force SIGMETs and AIRMETs whose area covers this field

AIRMET TANGO 1W: moderate turbulence below 18,000 ft (due to mountain wave) up to 12,000 ft.
AIRMET SIERRA 6E: mountains obscured by cloud (due to mountains obscured by clouds, precipitation, mist).

A SIGMET warns of weather hazardous to all aircraft (thunderstorms, severe turbulence or icing, volcanic ash); an AIRMET of weather that matters to small aircraft and to flying without instruments (moderate turbulence or icing, low cloud, strong surface wind, mountains hidden in cloud). An area is counted when it covers this field's position.

What pilots in the air told air traffic control or Flight Service: turbulence, icing, cloud tops and bases, temperature, wind, and whatever they remarked on (wind shear on final, a smooth ride). An urgent report is one of severe turbulence or icing, wind shear, or similar. Open "as filed, and in English" for the coded report and its translation line by line.

Temporary flight restrictions within 50 nautical miles, from the FAA's list

4/3635 DISNEYLAND THEME PARK, ANAHEIM,, CA 15 nm southwest · security · ZLA

Each restriction opens the FAA's own page with the exact area, heights and times. Ordinary notices to air missions (a closed runway, lights out, a crane) are not shown here: the FAA's notice search is not open to sites like this one at this time, and the application for the FAA's data feed is in hand.
