Weather; Aircraft; Procedure
Takeoff Teterboro Runway 24; winds variable 320-360 degrees; 12 KTS gusting to 30 KTS. Altitude Select set to 1;500 FT. LNAV Departure; VS as vertical mode. Departure - fly 240 degrees to WENTZ Intersection. Cross WENTZ at 1;500 FT - right turn to 280 degrees to RUUDY and maintain 2;000 FT. Windy conditions on departure and liftoff. At 1;300 FT and leveling; the autopilot disengaged due to moderate turbulence and strong winds. Immediately took control of the Global and flew manually. Due to turbulence I was unable to level at 1;500 FT. Global climbed to 1;800 FT - 1;900 FT when I finally was able to start descent to 1;500 FT approaching WENTZ. Crossing WENTZ I turned 280 degrees; turned back on the autopilot; called for 2;000 FT in the Altitude Select and climbed to approaching RUUDY. At no time was the aircraft out of control of in conflict with other aircraft.
A Global 700 autopilot disconnected on the TEB Runway 24 RUUDY 4 Departure at 1;300 FT due to turbulence and the pilot descended from 1;800 FT to cross WENTZ at 1;500 FT.
