Narrative:

We were assigned the teb 5 departure from runway 24. Departure was briefed between crew members to climb on runway heading to 1500 ft MSL then right turn to 280 degrees; maintain 1500 ft MSL til 4.5 DME from teb then climb to 2000 ft MSL. Altitude selector was set at 2000 ft. After departure and in turn to 280 degrees; first officer (myself) misinterpreted information on mfd and I began climb to 2000 ft. Captain immediately called altitude and I returned to 1500 ft MSL (maximum altitude reached was approximately 1900 ft MSL). I believe altitude alerter would have been better suited left at 1500 ft rather than set to final altitude on departure. Also aircraft is equipment for FMS departures and it would have greatly decreased workload and increased spatial orientation had it been armed and up for use. Both of these will be used on our next flight to teb.

Original NASA ASRS Text

Title: HS125 CREW EXCEEDS 1500 FT ON THE TEB 5 DEP PRIOR TO 4.5 DME.

Narrative: WE WERE ASSIGNED THE TEB 5 DEP FROM RWY 24. DEP WAS BRIEFED BETWEEN CREW MEMBERS TO CLB ON RWY HDG TO 1500 FT MSL THEN RIGHT TURN TO 280 DEGS; MAINTAIN 1500 FT MSL TIL 4.5 DME FROM TEB THEN CLB TO 2000 FT MSL. ALT SELECTOR WAS SET AT 2000 FT. AFTER DEP AND IN TURN TO 280 DEGS; FO (MYSELF) MISINTERPRETED INFO ON MFD AND I BEGAN CLB TO 2000 FT. CAPT IMMEDIATELY CALLED ALT AND I RETURNED TO 1500 FT MSL (MAX ALT REACHED WAS APPROX 1900 FT MSL). I BELIEVE ALT ALERTER WOULD HAVE BEEN BETTER SUITED LEFT AT 1500 FT RATHER THAN SET TO FINAL ALT ON DEP. ALSO ACFT IS EQUIP FOR FMS DEPS AND IT WOULD HAVE GREATLY DECREASED WORKLOAD AND INCREASED SPATIAL ORIENTATION HAD IT BEEN ARMED AND UP FOR USE. BOTH OF THESE WILL BE USED ON OUR NEXT FLT TO TEB.
