Which document lists altimeter setting procedures?

Which document lists altimeter setting procedures?

• A. ENR 1.7
• B. AIP ENR
• C. IFR Flight Plan Guide
• D. NOTAMs

Answer: (A)

Understanding how to set the altimeter correctly is essential for safe altitude interpretation and ATC communication. The procedures for altimeter settings are published in the Aeronautical Information Publication, in the Enroute (ENR) section, specifically in the part that lists altimeter setting rules. This part, ENR 1.7, provides the exact instructions for applying local pressure settings (like QNH or regional/barometric practices) and when to use the standard pressure setting as you move through different airspaces and transition levels. The other documents mentioned don’t contain these standard operational procedures: NOTAMs cover temporary notices and conditions, the IFR Flight Plan Guide explains how to file an IFR plan, and while AIP ENR as a whole covers enroute information, the specific altimeter setting procedures are found in ENR 1.7.
