I read the first edition of this book long ago and it really helped me form a solid basis for future learning. And it contributed to piquing my interest in the subjects of maps and navigation to such a degree that I'm still interested in learning more!
Just do a quick search and you'll find this book online. There are several other books available on related subject areas as well...
Thanks for your suggestions to . Is those concept necessary for flying Cessna 172, cause now I'm just only student pilot
