IFR rules are defined in which AIP section?

IFR rules are defined in which AIP section?

• A. ENR 1.3
• B. ENR 1.10
• C. ENR 5.1
• D. ENR 5.2

Answer: (A)

Instrument flight rules are the set of rules that govern flying when operating by reference to instruments, typically under weather conditions that require flight by instruments and ATC involvement. In the AIP structure, the En Route (ENR) section contains general flight rules applicable to aviation operations. Within ENR, the subsection that explicitly codifies IFR operations and the associated requirements (clearances, procedures, and conditions for instrument flight) is ENR 1.3. That’s why this section is the place where IFR rules are defined. The other ENR subsections cover different topics related to en-route information and operations, so they do not define the IFR rules.
