NCAA PPL Navigation case studies
NCAA PPL Navigation · Put your knowledge to work in context.
The NCAA Private Pilot Licence (PPL) Navigation Knowledge Test is the navigation subject examination set by the Nigeria Civil Aviation Authority for applicants working toward a PPL under Nigerian personnel licensing rules. It is a multiple-choice knowledge test aimed at student pilots who have completed navigation ground instruction at an approved training organisation and now need to demonstrate the theoretical knowledge required before, or alongside, their flight training. The examination covers the navigation content of the PPL syllabus, which the Authority publishes in Advisory Circular NCAA-AC-PEL 018 under Personnel Licensing Advisory Circulars on its website. Expect questions on chart work, dead reckoning, wind triangle and drift calculations, time-distance-fuel planning, position fixing, radio navigation aids, flight planning and the navigation aspects of cross-country preparation. The NCAA PPL Navigation case studies are 5 cases and about 2,797 words.
