This is the first in a series of videos to accompany the Instrument Ground School sponsored by EAA Chapter 1641 in Bloomsburg, PA. These videos are intended as a supplement to Rod Machado's Instrument Pilot's Handbook which may be obtained here: https://rodmachado.com/products/rod-m.... Students are advised to read each chapter, then watch the corresponding video, and finally to bring any questions they might have to our class meeting (be it virtual or in-person).
