This manual provides the knowledge required by candidates for the New Zealand Private Pilot and Commercial Pilot licences in Navigation and Flight Planning. The information in this manual is presented in a direct, easy to follow manner and many practical aspects of navigation are included. There are many aspects of Navigation and Flight Planning which overlap between the Private and Commercial Pilot syllabuses and for that reason it is felt that publishing the subject for both licences in one volume facilitates progressive learning. Any text which is for CPL students only is clearly marked. Chapters 10; 11 and 12 are totally for CPL students only and are so annotated in the chapter headings. The syllabus for CPL students lists a number of knowledge requirements in addition to those for the PPL. Thus all text not annotated `CPL Only' is required reading for both licences.
