🔍 Key Concepts

• U.S. Light List abbreviations for dayboard types (e.g., NA, NB, NC, etc.) • Difference between lateral aids (channel marking) and non‑lateral aids (information/regulatory) • How junction markers, range markers, and informational signs are shown in the Light List

💭 Think About

• First, recall what the letters in a dayboard type (such as NB) usually stand for and whether they denote color/shape, purpose, or both. • Compare which of the answer choices describe lateral channel‑marking functions versus informational/non‑lateral functions. • Ask yourself: if a dayboard has no lateral significance, how would that be reflected in the Light List notation and description?

✅ Before You Answer

• Look up how the Light List defines Type NB in its front explanatory pages or legend section. • Verify whether range dayboards have their own specific type code, separate from NB. • Confirm whether junction aids and black triangular dayboards are identified with different standard type codes in the Light List.
