    • Aircraft number and type

    • Departure airfield

Sources of weather information 1349676

  • Route of flight

  • Destination

  • Flight Altitude

  • Estimated time of departure

  • Estimated time enroute

Types of briefings
Types of Briefings

  • Standard is the most complete briefing and assumes no familiarity with the weather picture

  • Abbreviated is used to update weather information when you need only one or two specific items

  • It is designed to be a preliminary briefing tool. It is not intended to replace a standard briefing


  • Direct User Access Terminal System allows pilots with current medical certificates to receive weather and file flight plans with a personal computer and modem

  • If you have any question, you should contact a live briefer to help you interpret the raw data and to advise you on how or whether to complete a flight


  • DTC Duats


    • 1 800 245-3828

In flight weather sources
In-Flight Weather Sources

  • Airmets - WA - Airmans meteorological information are forecasts for a maximum of a six hour period

  • Sierra for IFR conditions

  • Tango for turbulence

  • Zulu for icing and freezing levels


  • Significant meteorological information - WS -

    • Severe Icing

    • Severe and extreme turbulence

    • Volcanic eruptions

    • Duststorms, sandstorms or volcanic ash lowering visibility to less than three miles

Convective sigmets
Convective SIGMETs

  • Imply severe or greater turbulence, severe icing and low level wind shear

  • Contain either an observation and a forecast or just a forecast for tornadoes, significant thunderstorm activity or hail 3/4 inch or greater in diameter

Enroute flight advisory service
Enroute Flight Advisory Service

  • Flight Watch is available daily from 6 AM to 10 PM when flying between 5,000 AGL and 17,500 MSL any where in the US

Center weather advisory cwa
Center Weather Advisory CWA

  • Issued by ARTCC to alert pilots of existing or anticipated adverse weather conditions

  • May be issued prior to an AIRMET or SIGMET as a result of PIREPs


  • Hazardous in-flight weather advisory service is a continuous broadcast of in-flight weather advisories over selected VORs or SIGMETs, convective SIGMETs, AIRMETs, severe weather warming alerts AWW, and Center weather advisories CWAs.
