In practical application on the 701 this amounts to full power and shortly thereafter rotate to climb attitude. As to the "clean and jerk" technique mentioned...a "jerk" would be considered bad form for any maneuver, even a snap roll. All control movements should be smooth, and in this case aggressive for the rotation. And to wait til 40 mph to rotate will lengthen the takeoff roll simply because it's so far above stall speed. As to the flaps...one notch will shorten the takeoff roll but reduce the angle of climb, so as soon as you have sufficient airspeed retract the flaps.

But often have to fly ground effect till airspeed builds. If engine were to fail in high nose up configuration the rotation back would be very difficult. Quote joe one notch will shorten the takeoff roll but reduce the angle of climb, Ross so if you are trying to clear 50ft obstacle as soon as possible . i find it may be better to start without flaps. no drag to start = faster accel =sooner airspeed liftoff=faster climb. if short field with obstacles is the problem i find a rolling start at some other angle including the opposite direction if there is room to turn. not long as the acceleration is quick but it can add a few feet. this method seems to be better than a standing start with brakes applied. I find you have to put rudder imputes in very soon after nose up and toes on the brakes hinders this. -------- Ross Aalexander: CH701 driver 912ul 490tt Read this topic online here: http://forums.matronics.com/viewtopic.php?p=352358#352358 ________________________________ Message 3 _____________________________________ Time: 02:24:27 PM PST US From: "Craig Payne" Subject: RE: Zenith701801-List: Re: What is your short takeoff technique ( pavement Umm, the stock flap lever on my 701 only has two positions - in and out. Can't do "one notch" or half.
