Proper procedure for LOOP SIX departure out of LAX

Featured Replies

Naw I never met him but we didn't cross through the other bases normally. I never flew the RJ either.There are actually three VFR routes through the LAX Class B. The shoreline route, which is the one that afftects the LAX departure, the special VFR flight rules corridor and the Hollywood Park route. The Shorline and Hollywood park routes require ATC clearance though.

Thanks to all for your comments and input.Noah-- I'm glad you were able to verify what I had seen.PMDG support - thanks for looking into this situation.What I left out was that I was taking off from 24R, and the sid calls for a heading of 250 degrees until you receive directions from ATC for vectors. Yes, I have used the FIX page in the FMC and have made it draw the SMO 160 radial and have displayed the 15 mile radius from the LAX vortac.Baring the abnomilies of the "canned" LOOP SIX departure, can you please tell me the proper way to perform just a single heading from the airport. So, if I want to takeoff and maintain a 250 degree heading (not manually flying all the way), what do you do?Do you arm HDG SEL, and then when the aircraft reaches 400 feet, turn on the autopilot? (and/or).......Do you arm LNAV, and then when the aircraft reaches 400 feet, turn on the autopilot?Thanks again to all for the help.Regards,Robert Amster

Any time there are altitude restrictions around SoCal, you can assume it's because another airport's traffic is going to be above/below that restriction.

I just flew this departure today and did not see what was described here. I hand flew with FD guidance up to 5000, left turn 8 DME from LAX towards LAX VOR and none of my waypoints disappeared. I am using an out of date AIRAC - maybe that's the difference?

I thought there were 4 bravo transitions at LAX, the coastal route, the mini route, the Hollywood Park route and the Coliseum routehttp://skyvector.com/?ll=33.852907438068875,-118.28887952918666&chart=114&zoom=3

Did fly it today and also did not encounter any abnormalities. I'am using AIRAC 1201.

There could be. I just got my info from AOPA. I don't have an LAX Class B chart any more so I'm not sure how many there are for sure.

I have been doing more testing and have found the following:

  • If I arm HDG SEL before takeoff, the way-points (Vectors and LAX) disappear after takeoff when I reach the INTC point. (By the way, I am using the AIRAC that came with the 737ngx).

Through experimentation, I finally found out a procedure that works all the time and doesn't delete the Vectors and LAX way-points. However, I don't know if this goes against SOP. Anyway, this is what I do now:

  1. Arm LNAV before takeoff and set the heading to 250 degrees (but I do not arm HDG SEL).
  2. Perform takeoff.
  3. At 400 feet, I engage the autopilot. Aircraft keeps on the 250 degree heading and the airspeed stays at approx. 167 knots.
  4. Select VNAV. The airspeed restriction disappears and the aircraft accelerates and then I can retract the flaps on schedule.
  5. ATC tells me to turn left at 200 degrees--I dial in 200 degrees and press HDG SEL and the aircraft turns smoothly to 200 degrees. (LNAV disengages)
  6. Later, ATC clears me direct to LAX. In the FMC, I select LAX, place it in the scratchpad, and then overwrite "vectors." I press EXEC on the FMC, then press LNAV. The aircraft proceeds to LAX and on to the rest of the SID.

I have done the above procedures five times in a row and it works very smoothly. However, I don't know if this mimics what pilots would do in the real world. So, any input would be appreciated. At least, the way-points are not longer deleted.Comments anyone?Regards,Robert Amster

Yep, Its on the Terminal, not on the sectional or IFR enroute charts. Yes there are 4 (including the special flight rules area), but the other three require that you still get class bravo clearnace and maintain communication with the tower. The Special Flight Rules corridor does not require clearance and does not require that you contact the tower, just that you squawk a particular code, think it's 1201, and that you report your position on the corridors ctaf and transition the Bravo at a specific altitude. This IS the biggest reason for the LAX altitude restrictions just off the 25's. Since the tower is not talking to the transiting VFR traffic, then they just make sure that nobody departing westboud climbs into the corridor. If you flew it you would be passing almost dirrectly over the coastguard hanger which is just west of midfield, but the safety margin is a few miles just to make sure.EDIT... Think it's also in the AFD.Edit.. One more just for correctness. The missed procedures should also have the altitude restrictions.
