Public Attributes

Type	Name
uint16_t	address DCS-BIOS address that drives the flag.
uint8_t	atVisualCol visual column the flag cell is inserted at (after this many digits)
bool	enabled false ⇒ no flag tape rendered (default)
const char *	faces face string, one char per state, e.g. "NS" / "EW" (nFaces = strlen)
uint16_t	mask field mask (A_4E_C_*_AM); 0xFFFF for whole-word
uint16_t	steps = 0 positions across the range; 0 ⇒ nFaces−1 (a full-scale flag)
float	widthMm flag cell width, mm (wider than a digit so a broad 'W' fits)

Detailed Description

Note:

OFF by default (enabled = false). Position is configurable (not hardcoded rightmost). Populate address / mask from the A4EC constants. The face is round(value/mask · steps), clamped to the face count.

Note:

steps matters because the A-4E-C does not drive every flag over the same range: the ASN-41 hemisphere arrives at HALF scale (nav.lua sets 0.0 or 0.5 for N/S and E/W, so steps = 2), while MagVar and the BDHI DME flag use the full range (0 or 1, so steps = 1). A half-scale flag read as full scale never reaches its second face.
