A minimalist app icon featuring a dark grey capital letter A stylized as a runway with a dashed center line and white base stripes.

Minimalist app icon logo, a single capital letter "A" rendered as one solid, continuous filled shape — like a bold sans-serif glyph. The letterform must be a solid filled silhouette, NOT an outlined or hollow letter, NOT double parallel lines with empty space between them. Each part of the letter is one solid mass of colour, with no interior gap. The solid A doubles as a stylized runway seen in forced perspective from a landing aircraft. The two outer diagonal edges converge upward, tapering the solid shape from a medium-weight base to a sharp, crisp point at the apex — the apex must stay pointed, not rounded, since it needs to read clearly as both a letter A and a converging runway vanishing point. The two base corners (bottom-left and bottom-right of the A) are softly rounded, creating a deliberate contrast: sharp and precise at the top, soft and approachable at the base. A solid horizontal crossbar connects the diagonals at the midpoint, exactly as in a normal letter A, also solid. Within the solid shape, use negative space (thin cutouts through the fill) for two runway details: a single dashed centreline running from the base up toward the apex, and 3–4 bold, chunky threshold marker stripes cut across the base of the A, spaced generously rather than densely — these must stay clearly legible and distinct even when the icon is scaled down to a small size (test mentally at ~50px), not fine hairline detailing that would clot into noise at small scale.
