CPL Navigation (Sri Lanka CAA Pilot Licence Examinations) case studies
CPL Navigation · Put your knowledge to work in context.
The CPL Navigation examination is the navigation subject within the Commercial Pilot Licence theory sequence administered by Australia's Civil Aviation Safety Authority (CASA). It is intended for candidates who already hold, or are working toward, a private pilot licence and now need to demonstrate the navigation knowledge required for commercial operations. The subject sits alongside the other CPL theory subjects and is normally attempted after human factors and meteorology, because flight planning depends on both. Content centres on the practical navigation task: preparing a flight plan, choosing tracks and altitudes, calculating heading and groundspeed from forecast winds, applying variation and deviation, managing fuel and endurance, and monitoring progress in flight. The CPL Navigation case studies are 5 cases and about 2,919 words.
