What activities are included in the Sail / Expedition / Gliding program?

The correct choice encompasses the essential skills related to both sailing and air navigation, which are fundamental components of the Sail / Expedition / Gliding program. This program aims to equip cadets with the knowledge and abilities required for safe and effective navigation in both water and air environments.

Water navigation skills involve understanding charts, currents, tides, and weather conditions necessary for sailing, while air navigation skills include the use of aeronautical charts, understanding airspace, and the principles of navigation in flight. Mastery of these skills is critical for successful participation in sailing and gliding activities, making this choice the most relevant to the program's objectives.

Other options relate to skills and knowledge that, while valuable in their respective areas, do not directly pertain to the dual focus on sailing and gliding. For instance, aerobatics and high-altitude training focus on advanced flight maneuvers rather than navigation. Land survival techniques are important but are more relevant to ground operations, and mechanics of aircraft maintenance focuses on the technical aspects of aircraft rather than navigation, making them less aligned with the program's goals.
