Under the Weather
Chesapeake Aviation Training, Inc. is happy to announce a two-day aviation weather safety workshop entitled “Under The Weather”.
FAA New England Region - Flight Standards Wings Listings The two-day workshop will be presented by Scott Dennstaedt. Scott is an FAA-certified instrument flight instructor (CFII), advanced ground instructor (AGI) and meteorologist who resides in Baltimore, Maryland. Besides presenting weather seminars, he is a contributing editor and writer for IFR and IFR Refresher magazines. "A pilot's goal is to minimize exposure to adverse weather." This workshop is designed to provide the pilot with essential aviation weather knowledge and explanation of web-based tools utilized to minimize exposure to two of aviation’s worst hazards, namely, icing and thunderstorms. This two-day scenario-based ground training course will introduce you to many aspects of aviation weather that are not taught in your basic aviation texts or ground school. The individual scenarios are designed to guide the pilot through many aspects of advanced preflight weather planning. Who should attend this workshop? If your weather planning consists of calling FSS or watching the Weather Channel, then this workshop will be a huge benefit. If you want to get beyond a basic DUATS briefing, then be prepared to expand your horizons. This is not a elementary course in aviation weather. The program will consist of two days of analyzing charts and diagrams while learning how to apply your basic aviation weather knowledge to see the expected conditions in a much clearer and precise way. The workshop is designed for the IFR pilot, however, even if you only fly VFR, this workshop will add a new dimension to your preflight toolbox. Do I need to have taken any prerequisite classes? It is helpful, but not mandatory to have attended the Weather or Not or Ice is NOT Nice workshops also given by Chesapeake Aviation Training. It is also recommended that you read Scott's weather-related IFR magazine articles prior to attending the workshop. OVERVIEW Chesapeake Aviation Training designed “Under The Weather” to be an aviation weather workshop that goes beyond a basic DUATS or FSS briefing. The workshop will bring together the basic elements of aviation weather with many techniques that will be new to the pilot using tools that are available free of charge on the Internet (join The Weather Report available on this web site for a comprehensive set of aviation weather links). The first day of the workshop will focus on the basic elements of weather forecasting tools and synoptic meteorology including forecasting models, upper air meteorology and sounding diagrams. The second day will start out discussing the various meteorological factors associated with structural icing. Finally, an interesting weather scenario will demonstrate the challenges a pilot might face when confronted with a flight where the potential of structural icing is likely. The scenario starts out looking at the weather several days prior to the planned departure. Even two or three days in advance, the potential for structural icing is apparent. This allows the pilot to begin to manage his or her schedule when the likelihood of adverse weather is forecast. The weather analysis continues right down to hours before the flight.

Understanding the meteorological big picture or what is known to meteorologists simply as the "synoptic" will underscore more of the weather challenges a pilot will face. The tendency for the pilot is to focus on the smaller-scale features of the atmosphere such as terminal forecasts, METARs or other surface-based features. Since a pilot only flies near the surface for a very short period of time, it is imperative that he/she also understands the dynamic weather elements at cruise altitude.
The first day of this weekend workshop will focus on many of the charts and diagrams used by meteorologists to assess the large scale motion of the atmosphere. This segment features a detailed discussion of numerical weather prediction model output to include Skew-T Log p diagrams, mean sea-level surface charts, constant pressure charts and many other useful aviation weather products. Key weather elements such as icing, instability, turbulence, precipitation and clouds will be discussed as they relate to the synoptic picture. Segment 2 – Icing Meteorological Factors:
In the segment, the student will learn about the meteorological factors that increase the likelihood of icing conditions. Icing conditions are more prevalent in cumuliform clouds as compared to stratiform clouds. 80% of the icing encounters reported by pilots were in a frontal zone. The dew point depression (temperature dew point spread) is a key indicator of the potential for icing conditions. Segments one and two will effectively encompass the material presented at the Ice Is NOT Nice workshop. Segment 3 – Icing Scenario: Our flying activity in the winter months is normally limited, primarily due to the continuous threat of structural icing. When visible moisture is present and the temperature aloft is below freezing, AIRMET Zulu becomes a common word in our preflight briefings. A typical flight planning scenario that has a significant icing threat will be discussed in detail. Long and short-range forecast products from forecasting models will be examined to aid in the decision-making process.
