Question

VRF charts contain information about seaports. For example, 00 - 50 in the formation block for HNL seems to be for a waterway:

Another example is 23W for 1C9:

Where are these conventions explained? I can't seem to find them in the Legend or User Guide.

"00 - 50" means a landing surface at 00 feet MSL, unlighted, and 5000 feet (nominal, 4970-5069 actual) long.

At aerodromes with both land and water surfaces, it is customary to suffix the water ones with "W" (pronounced Water, not Whiskey) to avoid confusion.

Do you have a reference for the W suffix? I found a reference about 00 - 50 on page 16 of the Aeronautical Chart User's Guide. – rvernica May 20 '20 at 04:32
@rvernica I've never looked for a reference, sorry. – StephenS May 20 '20 at 17:59
