Looking for 300ft in the air at departure end, in a Janus (assume two
seats loaded) at max GW take off from a 2200ft long runway is very optimistic. Our 260 HP Pawnees normally get around 600 fpm at 65 knots with a Janus (or Grob Twin for that matter) with two people. That's a climb angle of about 1:11. OK, so you can get a better angle with a slower speeed, but not *that* much better. Great explanations.. Our 235HP Pawnee will average about 400-500fpm with a two up 2-33 or Grob 103. And we break ground with about 1500ft runway remaining... so.. about 200ft at departure end. We are lifting off at about 55KIAS and towing at 60 for a 1-26 and 65 for the Grob. BT
