Which projection is used for constructing LO altitude charts?

• A. Lambert conformal conic
• B. Transverse Mercator
• C. Mercator
• D. Orthographic

Answer: (A)

The Lambert conformal conic projection is selected for constructing Low Altitude (LO) charts primarily due to its ability to accurately represent shapes and angles over mid-latitude areas, which is essential for aviation navigation. This projection maintains conformality, meaning that the scale is consistent and angles are preserved, which is critical for pilots when interpreting navigational information and making directional decisions. The Lambert conformal conic projection is particularly well-suited for aeronautical charts, as it allows for the depiction of airspace boundaries and navigational aids without significant distortion, making it easier for pilots to follow specific flight paths and understand the relative positions of features on the chart. This is especially important in the low altitude airspace where navigation can become complex due to the proximity to terrain and obstacles. In contrast, other projections like the Mercator projection can distort sizes and shapes significantly, which can mislead pilots in low-altitude navigation. Transverse Mercator, while useful for smaller areas, is less efficient for the broader cross-section of airspace depicted in LO charts. Orthographic projections, on the other hand, represent the earth as viewed from space and are not practical for navigational purposes since they don't preserve the necessary flight path information in a usable format for
