AVIATION WEATHER DEBBIE SCHAUM
Self- Briefing Procedures • Weather Awareness • Big picture, what’s the general weather along your route. • Look outside • Look at the weather on the TV • Get the big picture from your home computer
Self Briefing cont. • Are you ready to fly this mission? - Are you qualified to fly in these conditions? - Do you have the experience to take on this mission? - Are you physically capable? - Are you mentally ready?
Things you need to know • What type of aircraft • Limits of aircraft • Proposed flight level • Take off and destination forecast • Hazards enroute • Winds enroute • Time enroute
Weather information • Current weather • Surface analysis • Weather depiction • Radar summary • Satellite • METARS along route • Pireps
Weather Information Cont. • Forecast Weather • TAFS fortakeoff and departure • Prog charts valid for flight time • Hazard forecast valid for flight time • Hazards at your flight level • Discussion bulletins that apply to your route of flight
Alternates and Flight Paths • An Alternate is used if the weather at your destination is not suitable for landing. • Winds are too strong or creating too much of a crosswind • Thunderstorms/severe weather are over the field • Visibilities are below pilot’s/plane’s minimum capabilities • Ceiling is too low • Runway is icy or snow covered
ERAU WX • http://wx.erau.edu/data/ • Good satellite and radar images; access to WSI data; limited surface and forecast graphics; does not have upper air or model graphics data.
Then pick additional Information for your route of flight
Aviation Weather Center • http://aviationweather.gov/ • http://adds.aviationweather.gov/ • Good for aviation weather hazards; good satellite access; icing and turbulence information; pilot reports; some manual forecast graphics; access to experimental aviation hazard products (ADDS); lacks model data; lacks public weather
National Weather Service • http://weather.gov/ • Good overview of public weather; click on organization to get web listings for all local NWS offices
HOURLY WEATHER GRAPH Take off data Runway Cross winds Chance of Precip
NCAR-RAP • http://www.rap.ucar.edu/weather • Aviation oriented web page; forecast model graphics are useful aviation planning (clouds, winds, etc); has links to other related weather web sites. • Vertical profile data (Skew-T/Log P)
Using the ADDS Flight Planning Tool • Go to http://adds.aviationweather.gov/ • Click on Java Tools
Launch new FPT (Flight Path Tool) • Select your flight altitude
Click on Configure and Identify the items you want displayed
Creating a cross sectional view • Click on airplane button on left side. • Place cursor on starting location and left click (should put a 1 on that location) • Move your mouse to your destination and left click (should put a 2 on that location) • Continue to all your destinations • When complete right click and click on show cross-section.
Cross section cont. • This should display a cross section view. • It will always have your starting destination on the left side. • Along the bottom you will find all the information you requested by rolling over the points
METARS/TAFS • METAR is Meteorological Terminal Aviation Routine Weather Report • It is the observation of current conditions • By the time it is online it is old information • TAF is Terminal Airdrome Forecast • Provide a forecast of weather conditions at an airport for the next 6-24 hours.
