Interesting Paint Markings On Ramp

Sun Jul 17, 2011 3:56 pm

I just saw this cool picture by Diego Mancilla of a 777 at LAX.
http://www.airliners.net/photo/Emirates/Boeing-777-31H/ER/1952556/L/
I noticed that the plane isn't really following the yellow line, but then I noticed the dashed white line running somewhat along the yellow guide line. Is that white line for the tug driver to follow during push? I'm curious to know what it is. Thanks.

LAX airport is very tight at some places and you have to be pulled into the postition. You are not allowed to taxi on your own into the position. So you park close to your gate and cut the engine and will be pulled into the gate.
The dashed white lines look like they are some guidance for the pushback driver during pushback.

Ok thanks that's what I was thinking. It's just a really funny pattern with the little loop.

Is that a definite answer or a guess.Can anyone explain the route the Pushback truck would follow in the case above?.

It would push the aircraft back, following the white dashed line backwards, putting the aircraft with its tail to the right as seen from the picture and then pull forwards along the alleyway to give the aircraft a safe clearance at which point they would disconnect and the plane starts up and leaves. The clearances in the alleyways at LAX are pretty tight for widebodies.

I guess its only a bit misleading because the EK plane on the picture itself is being pushed facing the other direction (right) than the one which the white line is for (left).

I am in LAX right now and I will check at hour parking position later and ask some of the ground staff what these marks mean. I maybe can take a picture out of the cockpit to see the markings from another perspective.

While it doesn't look like he was exactly following the yellow line, he is pretty darn close to it when the photo was taken.

It looks like there may not be an aircraft parked at the next gate over (the gates at TBIT are quite close together for the airplane sizes that park there, hence towing in and out). So maybe he had some leeway on towing in. Although it occurs to me - do we know if that's a tow-in or a pushback?

That dashed white line does look funny though! A few too many beers before painting it, perhaps.

Based on the marshallers, it appears to be a pushback, they are looking towards the tail. Maybe the lines are for a specific airframe.

I'm going on my experience here as a push-back driver. The driver is using the solid white and yellow line which would be the same line the aircraft will use to come in. Why its white and yellow, no idea. All the ramps I've worked on, the lead in lines and alley lines are all yellow with a black outer line. Never seen a dotted taxi or lead in line before. Maybe sometimes the beginning of the line might be dotted with the rest being solid. That solid line though for sure is what the push-back driver is following and you don't have to be exactly on the line. You have a little room for error.

Thanks for the experienced explanation. I went on google maps and went to the TBIT gates on the south complex, and those white dashed lines don't just appear at gate 105 from the picture in that alley, but they appear in others, but that is the only gate with those shaped white dashed lines. It's interesting to note that they do not appear on the north complex of TBIT. It just leaves me baffled if those aren't the guides you guys in the tugs use.

If your referring to baggage tugs, there are service roads usually in front of the aircraft or behind the tail. That white dotted line though I was thinking is maybe for commuter planes but that doesn't make sense at these gates. It might however be a different way for the plane to come into the gate depending what plane is on the gate next to it. Ramp control might advise the pilot to use white dotted for lead in to the gate but I've never heard of that because usually gates with multiple lead lines are labeled alpha and bravo (12A, 12B) . There has to be someone that works at LAX to answer this because now I really wanna know. LOL

Haha yeah me too! Let me post this on Captain VIctor's blog...he's an LAX ATC. I'll see if he can answer.
