Short course in Aviation A Meteorology By Dr. Naser Sarhan

Introduction: Meteorological information and providing the necessary weather reports for the protection of aviation fields is one of the greatest responsibilities of specialists who work in the meteorological field.

Weather hazards represent one of the most challenging issues that aircrew may face. High winds, precipitation, turbulence, and thunderstorms are a definite threat to the safety of all resources on the air base or in the field. This includes equipment and personnel. This course will ll introduce you to the subject and help you understand nderstand the physical changes which occur in the atmosphere (dangerous dangerous weather phenomena and hazards hazards) and specifically for pilots and aircrew emphasize how to fly safely. This course builds on the basic information in general and aviation Meteorology Meteorology. The course is divided into chapters and has many workshops with exercises and homework which will contribute towards the assessment of a trainees' performance. Trainees will be asked to complete the relevant work both in class and as self study.

Performance objectives: The following are the objectives of teaching this course: 1. Using Meteorological

rules, techniques and knowledge to


Meteorological information satisfactorily to the trainees. 2. To provide trainees with a comprehensive and detailed view of the factors relevant to atmospheric changes and what causes atmospheric changes changes. 3. To gain a better understanding of Aviation A Meteorology and in--flight hazards. 4. To develop trainees skills on how to predict expected atmospheric changes from a given set of conditions. 5. To develop the trainee skills of sending, receiving and interpreting Meteorological information including the analysis analysi of present and future atmospheric conditions. 6. To train trainees to take appropriate precautionary decisions necessary for safe flying operations.
