To:Subject: RE: Pietenpol-List: Take off rollI can usually get off the ground in about 400 feet. 150 feet might bepossible with a 30 knot wind down the runway.Getting off the ground is not a problem with a Pietenpol. The problemcomes when trying to climb over 120 foot trees at the end of the runway(nobody ever told the trees in North Carolina that they are onlysupposed to be 50 feet tall). On a hot day, my rate of climb with a passenger is about 150 fpm.Assuming that it is moving forward at 50 mph (73 feet per second), andassuming I get off the ground after a 400 foot roll, that means I've gota little under 1 minute to climb high enough to get over the trees atthe end of the runway. To be generous, let's say the trees are only 100feet tall, so now I've got 40 seconds of flying time to get over thetrees. In that 40 seconds I will travel 40 x 73 or 2,920 feet. Problemis, the runway is only 2500 feet long and I've already used 400 feet ofit before getting off the ground.Solving the problem another way, if I take 400 feet to get off theground and then travel at 73 feet per second while climbing at 150 fpmfor the remaining 2100 feet of runway, I will be 71.92 feet high at theend of the runway, or will impact the trees 28 feet below the treetop.Hence my decision to not carry passengers out of my home field in thePietenpol.Jack PhillipsNX899JP-----Original Message-----

Using an A-65, operating at about 1000 lbs, from a 900' msl grass field, with a 72 X 42 prop in light winds the take-off roll is about 350 - 450 feet.Greg Cardinal----- Original Message -----
