A380 Catering Question Per Google Maps

Sun Nov 17, 2013 10:31 pm

So I was zoomed in on SYD international terminal on Google Maps, and a QF A380 is parked at the gate with what appears to be 4 catering trucks parked at the aircraft. One of the catering trucks is parked on aircraft right and is servicing the upper forward galley, and it appears like the base of the catering truck is parked inches from the #3 engine, and once the jackknives are extended and the bed extended, the truck is overtop the wing. I have two questions: 1) Is this a proper description of how catering trucks actually service the upper deck of the A380, and not just an optical illusion caused by Google Maps? 2) How did the FAA and/or Australia's version of the FAA sign off on this procedure as being safe? I know there are numerous ramp vehicles that come into very close proximity of the aircraft during ground servicing, but with the design of a catering truck, it doesn't seem like it would take much of a gust of wind to shift the jackknives into the #3 engine or the wing. I thank you for the answers in advance.

Fairly certain that its an optical illusion based on the fact you can see the inside of the engines would tell me the photo was shot from slightly forward of being directly over the A380
Must think up a new one soon, slow moving brain trying to get into gear ;)

They obviously didn't consider it a problem. Do a Google Images search for "A380 catering service" and you'll find many photos of A380s with catering vehicles servicing the upper deck door just forward of the wing. Two examples below.

Because it was deemed safe?

Only one instance I know of so far is an EK A380 in Canada where the catering truck had a hydraulic problem and damaged the upper surface of the wing, which required patching... There might be others, however the vehicles that service the upper deck (and probably lower deck too) have hydraulic arms to stabalise the vehicle during this process...
A306, A313, A319, A320, A321, A332, A343, A345, A346 A388, AC90, B06, B722, B732, B733, B735, B738, B744, B762, B772, B7

This airbus document should answer your question. Look at section 5.

Interesting question. Perhaps someone out there with more knowledge of FAA regulations can tell us if service vehicle design and operation are mandated in the aircraft certification requirements.

While the sat photo was taken at a slight angle, it's not enough to produce a simple optical illusion. If you can see from PDF in reply 4, and the photos in reply 2, the deck is actually above the wing. It appears a special truck is used, where the deck slides back before going down. In both the pics in reply 2, and the sat pic on Google Maps, you can see the bed of the truck is extended (longer then the other trucks). Quite a unique truck if you ask me.

I'm going to bump this topic. I came across the following photo which shows full catering service in progress, two sides of the aircraft. The photo is a nice addition to this thread and can be used as reference material in the future.

The body does indeed move forward, but looking at the pic showing the SQ being catered, it appears that the body moves forwards and backwards as part of the raising/lowering process -- the scissor arms need to be able to slide in order to allow the body to raise. If you look at the picture, you can see that the scissor arm connecting the back of the body and the front of the chassis appears to be permanently affixed at the hinge points. The front-of-body / rear-of-chassis arm can move. The two arms are affixed where they cross. The affect of this construction moves the body forward as it's being raised and backwards when it's being lowered. However, it doesn't actually move the body that much -- probably less than a meter in each direction (I'd have to scale the image to calculate it more accurately). The loading "bridge" is extended quite a bit in that image.

I believe there are wind limits for catering the upper deck like this.

There are wind limits for operating all catering trucks. Our airline says winds over 40kts no catering trucks.
