The teb 5 departure out of teb for runway 24 wants you to fly runway heading until 1500 ft and then turn to a heading of 280 degrees until passing the 4.5 DME from the teb VOR and then climb to 2000 feet. On our departure from teb I proceeded to fly runway heading and for some reason the flight director failed to capture the altitude of 1500 ft and overshot the initial altitude by 200 to 300 feet. Right away I proceeded to correct the altitude by going right back to 1500 ft and also at the same time started turning to the 280 degrees. A few seconds later we were told to contact new york departure and after that the flight went on normally. This event again shows that we should not rely solely on automation and first and foremost fly the airplane.

Title: HS125 FLT CREW REPORTS OVERSHOOTING THE INITIAL 1500 FT LEVEL OFF ON THE TEB 5 DEPARTURE DUE TO THE FLIGHT DIRECTOR'S FAILURE TO CAPTURE THE ALTITUDE.
Narrative: THE TEB 5 DEPARTURE OUT OF TEB FOR RUNWAY 24 WANTS YOU TO FLY RUNWAY HEADING UNTIL 1500 FT AND THEN TURN TO A HEADING OF 280 DEGREES UNTIL PASSING THE 4.5 DME FROM THE TEB VOR AND THEN CLIMB TO 2000 FEET. ON OUR DEPARTURE FROM TEB I PROCEEDED TO FLY RUNWAY HEADING AND FOR SOME REASON THE FLT DIRECTOR FAILED TO CAPTURE THE ALTITUDE OF 1500 FT AND OVERSHOT THE INITIAL ALTITUDE BY 200 TO 300 FEET. RIGHT AWAY I PROCEEDED TO CORRECT THE ALTITUDE BY GOING RIGHT BACK TO 1500 FT AND ALSO AT THE SAME TIME STARTED TURNING TO THE 280 DEGREES. A FEW SECONDS LATER WE WERE TOLD TO CONTACT NEW YORK DEPARTURE AND AFTER THAT THE FLIGHT WENT ON NORMALLY. THIS EVENT AGAIN SHOWS THAT WE SHOULD NOT RELY SOLELY ON AUTOMATION AND FIRST AND FOREMOST FLY THE AIRPLANE.
