This briefing is the most complete
What is a standard briefing?
This is regularly scheduled unless weather requires a SPECI-al one
What is a METAR
This means surface visibility is more than 6 statute miles
What is P6SM?
This provides surface conditions every three hours and graphically displays IFR and MVFR areas across the contiguous US
What is a weather depiction chart?
It has this symbol:
What is a cold front?
This provides valuable information from the air and can be routine or urgent
What is a PIREP or pilot report?
This is an operational interest to all aircraft but also warns of potentially hazardous weather to light aircraft
What is an AIRMET?
This obscuration level is the first to tell where the ceiling is
What is BKN?
VFR pilots use the low-level version of this to look 12 and 24 hours ahead
What is the significant weather prognostic chart?
is the symbol for this
What is fog?
This primary source of weather information can be called preflight or provide inflight briefing
This provides information on weather that possibly bad for everyone, but it's not thunderstorms
What is a SIGMET?
This weather observation for mist can be remembered as "baby rain"
Weather observations include wind and sky cover from reporting points across the country on this chart
What is the surface analysis chart?
You'll find them where you see this
What are rain showers?
This automated continuous broadcast is indicated by an "H" on aeronautical charts by the VORs providing it
What is High Intensity Weather Alert System or HIWAS?
This one's about thunderstorms and each one is valid for two hours
What is a convective SIGMET?
This lofty observation would look like 731960, if above FL240
What is winds from 230 at 119 knots, temperature -60 degrees celsius?
Air Route Traffic Control Centers (ARTCCs) can provide precipitation location and intensity information, but it can be up to this old
What is six minutes?
You'll prepare for it where you see this
What is a 50 kt wind?
This provides in-depth observations to surrounding communities about impending weather
What is doppler radar?
This warms of icing and freezing levels
What is an AIRMET Zulu?
This part of a forecast within five miles of the airport looks like this: PROB30 1200/1204 3SM TRSA BKN030CB
What is from 0000Z to 0400Z, on the 12th day of the month, there's a 30 percent probability of visibility at 3 statute miles, thunderstorms with moderate rain, and clouds broken at 3000 feet with cumulonimbus clouds
These charts issued twice a day are mostly for aeronautical decision making and preflight planning and should be viewed in light of current conditions
What are the 48- and 36-hour surface prognostic charts?
Get ready for that where you see this
What is sleet?
