Avionics Technician Handbook- Volume One: The Aircraft Technician's Handbook for Avionic System Familiarization and Troubleshooting First Edition

It covers Avionics systems not in current A&P school curriculums.

is ok

The book is over priced and contains so many spelling and grammatical errors that I quick counting them. The author should have hired someone to proof read it before it went to print. Also, some photos in it cover parts of paragraphs.
