Aeronautical Chart

The Aeronautical Chart theme is built from the FAA VFR sectional — the dense, color-coded paper map pilots fly with on visual navigation. Magenta and blue airspace rings, yellow city tints, and tan hypsometric terrain crowd an aged dark sheet, every feature labeled in condensed grotesque ink.

Nothing here is decorative. Each color is a defined code: magenta for non-towered and Class E surface airspace, blue for towered fields, yellow for urban area, tan for relief. The grid, the lat/long ticks, and the frequency boxes are functional furniture. Read it like a cockpit display at night, not a poster.

航空图主题取材自 FAA 的 VFR 航段图（sectional chart）—— 飞行员目视导航时随身携带的那张高密度彩色纸质地图。品红与蓝色的空域环、黄色的城市晕染、棕褐的等高地形层层叠在一张做旧的深色图纸上，每一处地物都用窄体无衬线油墨密密标注。

这里没有装饰，每种颜色都是一套被定义好的代码：品红代表非塔台与 E 类地表空域，蓝色代表设塔机场，黄色代表城区，棕褐代表地形起伏。网格、经纬度刻度、频率框都是功能性的版面构件。请把它当成夜航座舱里的一块显示面板来读，而不是一张海报。
