Distance Learning Aviation Courses - DLAC 2: Producing Customer-Focused TAFs

DLAC 2 Distance Learning Course
    • Información de inscripción:


Excessive use of conditional language, overly long TAFs, and TAFs that are not amended in a timely manner are some of the things that hamper the end user's ability to understand the forecast and make correct decisions, often resulting in substantial negative economic impact. DLAC 2 addresses these problems by focusing on issues such as:

  • How TAFs impact aviation forecast customers
  • The importance of effective communication between the forecaster and customers
  • The need for collaboration and coordination with other offices issuing aviation forecasts, and
  • How to create TAFs that maximize the usefulness of NWS forecasts to the customer


Objetivos generales y específicos

  1. Describe how TAFs impact customers
  2. Write clear and concise TAFs that customers understand
  3. Produce relevant and timely TAFs by being aware of customer needs and expected weather
  4. Express TAF logic and uncertainty via aviation forecast discussions
  5. Collaborate with others to produce the most consistent TAFs possible
  6. Routinely produce the best TAFs by using aviation "best practices"

Descripción general

The Distance Learning Aviation Courses (DLAC) are a series of lessons, units, and cases designed to help aviation forecasters improve both their ability to forecast aviation hazards and to write terminal aerodrome forecasts (TAFs) that convey these hazards to aviation forecast customers.


The overall objectives for the DLAC courses are to:

  • Develop an increased awareness of the various users of aviation forecasts and how forecasts of aviation hazards impact (both positively and negatively) aviation operations within each user group
  • Explain the significant physical mechanisms and weather patterns responsible for aviation hazards
  • Give forecasters an understanding of observations, forecast tools, and model data that can help improve the forecasting of aviation hazards
  • Provide practice in writing a TAF that is user-friendly

Courses and Resources

Courses currently available are:

  • DLAC 1: Forecasting Fog/Low Stratus for Aviation Operations: Provides a comprehensive understanding of the physical mechanisms, synoptic patterns, and mesoscale features involved in fog/stratus generation and dissipation, as well as the latest forecast tools used to predict these challenging events. Introduces the Practically Perfect TAF (PP TAF) method for conveying ceiling and visibility information in a TAF.
  • DLAC 2: Producing Customer-Focused TAFs: Emphasizes understanding how aviation customers use TAFs, how weather hazards conveyed in TAFs affect their decisions, and what constitutes a "good" or "poor" TAF from the customer's viewpoint. Also reviews the PP TAF technique introduced in DLAC 1 and provides additional practice in writing PP TAFs for various weather conditions.
