Narrative:

Teb departure was radar idented and given a turn to 190 degrees with a turbojet directly overhead and descending on 220 degrees. Separation was immediately lost! This event is the result of an extremely dangerous departure procedure used at teb at the N90 TRACON. The teb dalton 19 departure presents the potential for numerous dangerous conflicts. This procedure with the exception of noise abatement concerns has numerous faults and violates almost every known common sense application of ATC: 1) due to a loophole in the air traffic manual, teb departures are put in dangerous proximity to ewr heavy jet arrs on a routine basis (ie, less than 5 mi and 1000 ft) as well as standard separation on all other types. 2) the wording of the dalton 19 departure places the teb departure aircraft alarmingly close to class B airspace, ewr runway 22 final, and terrain. 3) the event of a wrong move by either the aircraft or the controller can result in serious consequences without any time for recovery. Callback conversation with reporter revealed the following information: reporter stated he had filed an unsatisfactory condition report (ucr) concerning the teb dalton departure procedure because of safety concerns. The departure is used mostly by cpr pilots, many of whom are not very familiar with the procedure at teb. He said there are frequent incidents of pilots turning late, or exceeding speed and altitude limits. He said providing wake turbulence separation is difficult if not impossible because of the proximity of overhead traffic to ewr. He thinks an LOA concerning heavy aircraft separation should be written and a briefing given to pilots before they use the departure.

Title: ACR DEPARTED TEB ON THE DALTON DEP PROC AND CONFLICTED WITH TFC INBOUND TO EWR RESULTING IN AN OPERROR.

Narrative: TEB DEP WAS RADAR IDENTED AND GIVEN A TURN TO 190 DEGS WITH A TURBOJET DIRECTLY OVERHEAD AND DSNDING ON 220 DEGS. SEPARATION WAS IMMEDIATELY LOST! THIS EVENT IS THE RESULT OF AN EXTREMELY DANGEROUS DEP PROC USED AT TEB AT THE N90 TRACON. THE TEB DALTON 19 DEP PRESENTS THE POTENTIAL FOR NUMEROUS DANGEROUS CONFLICTS. THIS PROC WITH THE EXCEPTION OF NOISE ABATEMENT CONCERNS HAS NUMEROUS FAULTS AND VIOLATES ALMOST EVERY KNOWN COMMON SENSE APPLICATION OF ATC: 1) DUE TO A LOOPHOLE IN THE AIR TFC MANUAL, TEB DEPS ARE PUT IN DANGEROUS PROX TO EWR HVY JET ARRS ON A ROUTINE BASIS (IE, LESS THAN 5 MI AND 1000 FT) AS WELL AS STANDARD SEPARATION ON ALL OTHER TYPES. 2) THE WORDING OF THE DALTON 19 DEP PLACES THE TEB DEP ACFT ALARMINGLY CLOSE TO CLASS B AIRSPACE, EWR RWY 22 FINAL, AND TERRAIN. 3) THE EVENT OF A WRONG MOVE BY EITHER THE ACFT OR THE CTLR CAN RESULT IN SERIOUS CONSEQUENCES WITHOUT ANY TIME FOR RECOVERY. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR STATED HE HAD FILED AN UNSATISFACTORY CONDITION RPT (UCR) CONCERNING THE TEB DALTON DEP PROC BECAUSE OF SAFETY CONCERNS. THE DEP IS USED MOSTLY BY CPR PLTS, MANY OF WHOM ARE NOT VERY FAMILIAR WITH THE PROC AT TEB. HE SAID THERE ARE FREQUENT INCIDENTS OF PLTS TURNING LATE, OR EXCEEDING SPD AND ALT LIMITS. HE SAID PROVIDING WAKE TURB SEPARATION IS DIFFICULT IF NOT IMPOSSIBLE BECAUSE OF THE PROX OF OVERHEAD TFC TO EWR. HE THINKS AN LOA CONCERNING HVY ACFT SEPARATION SHOULD BE WRITTEN AND A BRIEFING GIVEN TO PLTS BEFORE THEY USE THE DEP.
