    Variable NAVAID_TYPESConst

    NAVAID_TYPES: readonly [
        "VOR",
        "VORTAC",
        "VOR/DME",

    ] = ...

    The full set of NavaidType values, in declaration order.

    Use as the single source of truth for value-side iteration (e.g. building a lookup table keyed by navaid type) or with isNavaidType to narrow an external string into the union. The as const satisfies brand keeps this array in sync with the type at compile time.
