Ring Altitudes MSL (default)

MacCready: 0.0 kt

Expected thermal climb rate for optimal speed-to-fly. 0 = best glide. Applies to gliders with polar data.

Safety Factor: 0.50

Reduces effective glide ratio (0.5 = 50% of best glide)

Min. Arrival Altitude AGL: 1000 ft

Height above field needed to set up a landing pattern (added to glide ring calculation)

Terrain-Aware Rings

Checks terrain along the glide path. Flat-earth rings display first while terrain data loads.

Min Terrain Clearance:

Minimum AGL height maintained above terrain throughout the entire glide path. Segments below this show orange; terrain hits show red.

Wind

Speed: From:

Direction wind is blowing FROM (0°=N, 90°=E, 180°=S, 270°=W). Rings and glide paths adjust for headwind/tailwind.
