Designed as a technical reference for instrument-rated pilots who want to maximize their skills in an “Instrument Flight Rules” environment, this revised and up-to-date edition of the Federal Aviation Administration’s Instrument Procedures Handbook contains the most current information on FAA regulations, the latest changes to procedures, and guidance on how to operate safely within the National Airspace System in all conditions. Featuring an index, an appendix, a glossary, full-color photos, and illustrations, Instrument Procedures Handbook is the most authoritative book on instrument use anywhere.
It’s the same thing with the IFH… please just combine the two. I felt like this one had barely enough info to stand alone but it somehow still did. Why?
With the Instrument Flying Handbook, everything you need to pass FAA's Instrument written test. Could be usefully supplemented with, say, Jeppesen's Instrument/Commercial book (which has great graphics), but still a great resource.
