    "data": {
        "note": "Endurance = usable fuel ÷ the burn rate. The legal and sensible move is to hold back a reserve — 30 min day / 45 min night VFR, 45 min IFR is typical — so the usable endurance is the time you can actually plan to, not the tanks-dry figure. Burn rises with power and richer mixtures, so use a realistic cruise number, not the brochure best case.",
