Which document summarizes the regulations for IFR operations?

The Federal Aviation Regulations (FAR) is the correct answer because it serves as the comprehensive set of rules governing all aspects of civil aviation in the United States, including regulations pertinent to Instrument Flight Rules (IFR) operations. It outlines the specific requirements that pilots must adhere to for safely conducting flights under IFR, such as visibility minima, equipment requirements, and airspace regulations. This foundational document establishes the legal framework that ensures safety and compliance in aviation practices.

In contrast, other options like The Airman’s Information Manual and The Aviation Safety Handbook provide valuable information and guidance but do not serve as legal regulations. The Pilot’s Guide to IFR Flight may contain useful tips and best practices for pilots flying under IFR, but it does not consolidate the regulatory framework as comprehensively as the FAR does. Thus, while all these documents are important resources for pilots, the FAR uniquely fulfills the role of summarizing the regulations that govern IFR operations.
