Narrative:

Teb 5 departure. Runway 24. I briefed the departure and noted the altitudes and DME requirement. I climbed to 1500 ft and began my turn to heading 280 degrees. The leveloff was made using the flight director command bars. The altitude capture mode had not yet been made. Coincidentally with the leveloff; the altitude alert was moved to 2000 ft. I followed the command to 2000 ft for the leveloff. The problem is that the 2000 ft altitude is to be reached at 4.5 DME from teb VOR. At this point we were about 3.0 DME. The new york approach controller told us of our error. We did not receive a TCAS alert. The error occurred because I was not specific enough about what to do with the altitude alert system in relation to the DME 4.5 fix. I have flown this departure on a number of occasions without a problem. I believe a contributing factor was the fact I had not flown in the previous 63 days. I was lacking in situational awareness; and was not as focused as I should have been. Oddly; the departure procedure was a concern and I thought I had 'covered the bases.'

Title: FLT CREW HAS AN ALTDEV DURING THE TEB 5 DEP.

Narrative: TEB 5 DEP. RWY 24. I BRIEFED THE DEP AND NOTED THE ALTS AND DME REQUIREMENT. I CLBED TO 1500 FT AND BEGAN MY TURN TO HDG 280 DEGS. THE LEVELOFF WAS MADE USING THE FLT DIRECTOR COMMAND BARS. THE ALT CAPTURE MODE HAD NOT YET BEEN MADE. COINCIDENTALLY WITH THE LEVELOFF; THE ALT ALERT WAS MOVED TO 2000 FT. I FOLLOWED THE COMMAND TO 2000 FT FOR THE LEVELOFF. THE PROB IS THAT THE 2000 FT ALT IS TO BE REACHED AT 4.5 DME FROM TEB VOR. AT THIS POINT WE WERE ABOUT 3.0 DME. THE NEW YORK APCH CTLR TOLD US OF OUR ERROR. WE DID NOT RECEIVE A TCAS ALERT. THE ERROR OCCURRED BECAUSE I WAS NOT SPECIFIC ENOUGH ABOUT WHAT TO DO WITH THE ALT ALERT SYS IN RELATION TO THE DME 4.5 FIX. I HAVE FLOWN THIS DEP ON A NUMBER OF OCCASIONS WITHOUT A PROB. I BELIEVE A CONTRIBUTING FACTOR WAS THE FACT I HAD NOT FLOWN IN THE PREVIOUS 63 DAYS. I WAS LACKING IN SITUATIONAL AWARENESS; AND WAS NOT AS FOCUSED AS I SHOULD HAVE BEEN. ODDLY; THE DEP PROC WAS A CONCERN AND I THOUGHT I HAD 'COVERED THE BASES.'
