those Officer Cadets who finish the Core syllabus with time remaining on the squadron, an advanced syllabus has recently been introduced consisting of Aerobatics, Formation Flying and Low Level Navigation. There is no specific time requirement as with the core syllabus, as progress in the advanced phase is made at a rate by which the student pilot is able to achieve the desired results. Ground Training Beyond flying, UASs follow a loose Ground Training syllabus. Although squadrons generally do not follow the syllabus as a training plan, the majority of subjects are covered at some point through the students' academic year. These can include attending Adventure Training expeditions, both overseas and within the UK, learning drill, undertaking a fieldcraft exercise such as the recent 'STRIKE' exercises run from RAFC Cranwell, understanding the principles of air power and developing leadership skills. Air Power Force Development Experiences are also undertaken to encourage an understanding of air power in both a historical and contemporary context. As the UAS continues to move beyond its former role of providing Elementary Flying Training to RAF Direct Entry students and UAS Students, more and more ground training opportunities are becoming available, making the UASs more suitable for Officer Cadets pursuing careers in the military other than aircrew. However, the emphasis and priority remain on flying as the core function of each UAS. In 2003 it was estimated that 60% of pilots recruited into the Royal Air Force came through the UAS system. UAS Officer Cadets are required to participate in a minimum amount of training: one training night a week during the university terms) which usually entails a guest speaker presenting on an aspect of the RAF or the military to develop service knowledge; and a two-week period of continuous training in the summer. Most squadrons however also offer camps at Easter, Christmas, and September for Officer Cadets to undertake intensive blocs of sport, flying and adventure training. Additionally, students are offered a limited number week-long Summer Vacation Attachment (SVA) at another RAF base, where they are seconded to an active regular RAF unit to learn more about their role. Adventurous Personal Development Training (APDT) In accordance with the ground training syllabus, there are opportunities for Officer Cadets to participate in APDT. There are frequent squadron expeditions in areas within the UK and overseas in Europe as well as Peru, Canada and Mongolia. Expeditions can include all
