I don’t have the books but I would bet a 550 with not much fuel at sea level on a cool day could get airborne in about 2000 ft. A light G2 under the same conditions has a BFL of less than 3000 ft., figure with everything running the ground roll would be a good 500 feet less than that. more or less.
G2: 500 MSL, 15C, 0 wind, BOW 38,000, TOW 44,000, BFL is 2960.
on the other hand, 500 MSL, 35C, 0 wind, TOW 64,800, BFL is 7340. (Max temp at that weight is 37C)
