Narrative:
While departing teb runway 24; TEB5 departure; we used VNAV feature for vertical flight management. According to our procedures; we set 2000 ft as the climb altitude with the expectation that the FMS would cue us to climb the aircraft on the TEB5 climb schedule. The TEB5 departure calls for a climb to 1500 ft followed by a right turn through teb 4.5 DME and then climb to 2000 ft. Instead of leveling the aircraft at 1500 ft; we climbed directly to 2000 ft by following the flight director. Upon reviewing the FMS; we realized that the departure in the FMS did not include the level off at 1500 ft and thus the use of the VNAV guidance mode was not appropriate. That mistake led directly to our error. The departure controller informed us of our error and we descended to 1500 ft.
Original NASA ASRS Text
Title: A BD700 DEPARTING ON THE TEB 5 EXCEEDED THE 1500 FT LEVEL OFF ALT BECAUSE THE MCP ALT WAS SET AT 2000 FT AND THE VNAV PATH DID NOT INCLUDE A 1500 FT CONSTRAINT.
Narrative: WHILE DEPARTING TEB RWY 24; TEB5 DEP; WE USED VNAV FEATURE FOR VERT FLT MANAGEMENT. ACCORDING TO OUR PROCS; WE SET 2000 FT AS THE CLB ALT WITH THE EXPECTATION THAT THE FMS WOULD CUE US TO CLB THE ACFT ON THE TEB5 CLB SCHEDULE. THE TEB5 DEP CALLS FOR A CLB TO 1500 FT FOLLOWED BY A RIGHT TURN THROUGH TEB 4.5 DME AND THEN CLB TO 2000 FT. INSTEAD OF LEVELING THE ACFT AT 1500 FT; WE CLBED DIRECTLY TO 2000 FT BY FOLLOWING THE FLT DIRECTOR. UPON REVIEWING THE FMS; WE REALIZED THAT THE DEP IN THE FMS DID NOT INCLUDE THE LEVEL OFF AT 1500 FT AND THUS THE USE OF THE VNAV GUIDANCE MODE WAS NOT APPROPRIATE. THAT MISTAKE LED DIRECTLY TO OUR ERROR. THE DEP CTLR INFORMED US OF OUR ERROR AND WE DESCENDED TO 1500 FT.
