🔍 Key Concepts

• Astronomical refraction tables in the Nautical Almanac assume a standard atmosphere • Standard atmosphere is defined by both a standard temperature and standard sea-level pressure • Typical meteorological "standard pressure" values used in navigation and aviation (compare inches of mercury to millibars)

💭 Think About

• Which of the listed pressures is closest to the commonly quoted standard sea-level pressure in millibars? Convert each inches-of-mercury value to its millibar value and compare. • Think about what value pilots and navigators usually use when talking about a "standard atmosphere"—does it look closer to 1000 mb, 1010 mb, 1013 mb, or 1015 mb? • Refraction tables are built on a long‑established convention, not an odd or rounded value. Which option looks like that long‑standing convention?

✅ Before You Answer

• Convert each option’s inches of mercury to millibars and see which is nearest standard sea-level pressure used in meteorology/aviation. • Compare each millibar value to the commonly cited 1013.25 mb reference; which option is closest? • Remember the Almanac is based on an ideal standard atmosphere, not on a low or high weather system pressure. Eliminate values that look more like low/high pressure than the norm.
