<br/><br/> The book delivers a great curriculum on air radio navigation and instrument flying. Essential for those wishing to push further beyond the PPL and get the Instrument Rating. The author Trevor Thom is a leading authority in flying training and I find it convenient to have his full 7-volume series handy. It continues to serve as a reference to consult and go back to whenever one needs to check something or refresh their basics.
