        "note": "Glide ratio = forward speed ÷ sink rate (in the same units): 60 kt (≈ 6,076 ft/min) at a 600 ft/min sink is about 10:1, a 5.7° glide path. It is the slope of the glide, read straight off the aircraft's polar — gliders reach 40–60:1, a light single ~9:1, an airliner ~17:1. The best ratio comes at one particular speed; fly faster or slower and the sink rate rises, steepening the glide.",
