Question 939Navigation General

The correct answer is D) directly in front of the pointer. To accurately read an aneroid barometer, your eye should be placed directly in front of the pointer, allowing you to align your line of sight perpendicular to the scale. This ensures that you are reading the pressure value at the exact point where the pointer intersects the scale, avoiding any parallax error that could occur if your eye was positioned to the left or right of the pointer. The other options are incorrect because reading the scale from the left or right of the pointer (A and C) can introduce parallax error, and reading above the meniscus (B) is not the proper way to read an aneroid barometer, which does not have a meniscus like a liquid-filled instrument.
