Narrative:
This is just 1 example of a major problem being ignored in the FAA. The ZLA control tower is equipped with a 'restrict light.' the TRACON turns the light on when they are running VFR aircraft below 3500 ft along the shoreline. Tower controllers then issue 2000 ft to all departures. When the light is off, departures are issued 3000 ft. On many occasions the TRACON fails to turn the light on in a timely manner and aircraft nearing the shoreline with the 3000 ft restr must stop climbing and level off quickly. Also, the lax tower management requires the 3000 ft altitude be issued with the takeoff clearance. On numerous occasions the 3000 ft has been issued and the aircraft is rolling when the 'restrict light' is activated, and the aircraft must be reissued 2000 ft. In the incident on the front, the aircraft was issued 3000 ft and cleared for takeoff. As the aircraft was rolling the 'restrict light' was turned on. When the aircraft was safely airborne the controller attempted to reissue 2000 ft but the aircraft had already switched to departure frequency on their own. By the time the aircraft checked in on departure frequency, the incident had occurred. This incident resulted in the decertification of 2 fpl's at los angeles. Since this incident an FAA operational assessment team has visited lax tower and lax sector of socal TRACON and recommended the 'restrict light' be removed and 1 standard altitude to all departures. Unfortunately lax tower is in the middle between TRACON and air traffic area. TRACON insists VFR inbounds to smo and other VFR traffic must be at 2500 ft along the shoreline. While the air traffic area insists the new generation aircraft need higher altitudes to eliminate the autothrottles from coming back soon after departure and scaring the passenger. In the past 8 yrs, 10 operrors at lax tower have been caused by this 'restrict light.'
Original NASA ASRS Text
Title: LAX ATCT RPTR CLAIMS THAT THE TRACON ALT RESTR LIGHT WAS ACTIVATED TOO LATE TO CHANGE THE ALT OF A DEP FROM LAX WBOUND. ACR CHANGED TO DEP CTL BEFORE LCL CTLR COULD REISSUE 2000 FT. CONFLICTING TFC WAS ON THE VFR SHORELINE RTE AT 2500 FT.
Narrative: THIS IS JUST 1 EXAMPLE OF A MAJOR PROB BEING IGNORED IN THE FAA. THE ZLA CTL TWR IS EQUIPPED WITH A 'RESTRICT LIGHT.' THE TRACON TURNS THE LIGHT ON WHEN THEY ARE RUNNING VFR ACFT BELOW 3500 FT ALONG THE SHORELINE. TWR CTLRS THEN ISSUE 2000 FT TO ALL DEPS. WHEN THE LIGHT IS OFF, DEPS ARE ISSUED 3000 FT. ON MANY OCCASIONS THE TRACON FAILS TO TURN THE LIGHT ON IN A TIMELY MANNER AND ACFT NEARING THE SHORELINE WITH THE 3000 FT RESTR MUST STOP CLBING AND LEVEL OFF QUICKLY. ALSO, THE LAX TWR MGMNT REQUIRES THE 3000 FT ALT BE ISSUED WITH THE TKOF CLRNC. ON NUMEROUS OCCASIONS THE 3000 FT HAS BEEN ISSUED AND THE ACFT IS ROLLING WHEN THE 'RESTRICT LIGHT' IS ACTIVATED, AND THE ACFT MUST BE REISSUED 2000 FT. IN THE INCIDENT ON THE FRONT, THE ACFT WAS ISSUED 3000 FT AND CLRED FOR TKOF. AS THE ACFT WAS ROLLING THE 'RESTRICT LIGHT' WAS TURNED ON. WHEN THE ACFT WAS SAFELY AIRBORNE THE CTLR ATTEMPTED TO REISSUE 2000 FT BUT THE ACFT HAD ALREADY SWITCHED TO DEP FREQ ON THEIR OWN. BY THE TIME THE ACFT CHKED IN ON DEP FREQ, THE INCIDENT HAD OCCURRED. THIS INCIDENT RESULTED IN THE DECERTIFICATION OF 2 FPL'S AT LOS ANGELES. SINCE THIS INCIDENT AN FAA OPERATIONAL ASSESSMENT TEAM HAS VISITED LAX TWR AND LAX SECTOR OF SOCAL TRACON AND RECOMMENDED THE 'RESTRICT LIGHT' BE REMOVED AND 1 STANDARD ALT TO ALL DEPS. UNFORTUNATELY LAX TWR IS IN THE MIDDLE BTWN TRACON AND ATA. TRACON INSISTS VFR INBOUNDS TO SMO AND OTHER VFR TFC MUST BE AT 2500 FT ALONG THE SHORELINE. WHILE THE ATA INSISTS THE NEW GENERATION ACFT NEED HIGHER ALTS TO ELIMINATE THE AUTOTHROTTLES FROM COMING BACK SOON AFTER DEP AND SCARING THE PAX. IN THE PAST 8 YRS, 10 OPERRORS AT LAX TWR HAVE BEEN CAUSED BY THIS 'RESTRICT LIGHT.'
