The rate of change in the field of avionics is so fast that even the
legislators are struggling to keep up with it. With new digital
cockpits, it is getting to the stage that, if your VCR still flashes
12:00, you will have no business flying a modern aircraft! The majority
of twin-engined (and many single-engined) aircraft now have complex
autopilots, glass cockpits and navigation equipment, possibly including
Flight Management Systems (FMS). This book originated with a request
from the RCAF for training materials for engineers, but curious pilots
whose training syllabus did not include avionics, and who would like to
know a little more will find it useful as well.
