The Aero-Mod Intl. book I've got (65-ARs) shows at sea level on a 25c day, no wind or slope, about 3700 feet to make it to 35 feet weighting 24,000 pounds. Up it to 26,900 and it's around 5200-5300 feet. Accel-stop is always a lower number. Second segment is 2% gross at 26,900, I've forgotten what the turboprop requirement is.
