1. Aerospace Lesson January 26 2009 Objective Objective By the end of this lesson cadets and seniors will be able to use a weather map to make a flight plan and chart it on a map.

2. Agenda I. Quick Overview of Weather maps and terminology 10-15 minutes II. Cadets and Seniors will be divided into groups to make a flight plan using the information from the weather maps in the presentation. 30-40 minutes

3. Agenda Continued  Mark out the relevant weather factors for the flight plan on the map  Choose the best flight plan, starting time etc as shown on your assignment sheet  One representative from each group will present their weather map and flight plan. 10-15 minutes  Captain Goude will judge the presentations and maps

4. Directions You do not need to be an expert in weather patterns to complete this assignment.  Use the information from the weather reports to make an informed decision on what course to take.  Discuss options with your team  Keep safety first  Notice the changes in weather. Decide the best time to leave based on the weather predictions. Notice different routes that you may take to reach your destination.

7. Cold Front A cold front demarcates the leading edge of a cold air mass displacing a warmer air mass.

8. Warm Front A warm front is the leading edge of a warmer air mass replacing a colder air mass.

9. Stationary Front If the front is essentially not moving (i.e. the air masses are not moving) it is called a stationary front.

10. Occluded Fronts Occluded fronts can be identified on weather charts as bold lines with sets of triangles and semi-circles. These are colored purple on colored weather charts. The direction in which the symbols face indicates the direction in which the front is traveling Occlusions are formed when the cold front overtakes the warm front, therefore they have similar characteristics to a cold front, but less intense.
