🔍 Key Concepts

• How the Army Corps of Engineers (ACOE) river charts show river mileage (what the reference point is) • What a light’s characteristic means on a chart (e.g., Fl R 4s, Iso G 6s, etc.) • How aids to navigation are labeled on river navigation charts versus coastal charts

💭 Think About

• Ask yourself: On an ACOE river chart, when you look at a light symbol, what TWO pieces of information are normally right next to it? • Think about whether river charts emphasize the name of the aid or the river mile and light characteristic to help pilots navigate. • Consider what the abbreviation A.H.P. usually stands for in the context of major rivers like the Mississippi, and how that ties into chart labeling.

✅ Before You Answer

• Verify what A.H.P. means in river navigation (e.g., above which specific reference point). • Check a sample Army Corps river chart and see whether lights are primarily identified by a name, by their light characteristic, or by another feature. • Confirm whether river miles on these charts are measured from a fixed reference point (like a pass, head of navigation, or river mouth) and how that appears in the labeling.
