Airports and ULD

Airports and ULD

Airports, love them or hate them, the airline industry cannot do without them, and indeed have little choice about which airports they use, as generally there is only one available airport in any one destination, so good or bad, large or small, airlines have to work with what they can get.

When it comes to ULD and airports there are a number of issues, which we will address in this article:

 

Operational:

If we start with basics, today’s aircraft such as the 787, 777 and A350 XWB carry roughly double the number of ULD their predecessors of only 40 years ago carried. This development is not widely recognized, airports have not, in general, taken into account that each of these aircraft will unload and reload double the number of ULD from even 20 years ago. When we look at freighters the increase is not quite as high, but we are still looking at 20% more ULD and bear in mind that each of these is a PMC pallet that requires a great deal more space than an AKE. This development has two immediate effects

  1. During loading and unloading there is a need for more dollies and more activity around the aircraft, yet the typical parking bay is no different than it was with the arrival of the first wide-body aircraft
  2. Once unloaded from the aircraft and emptied of their baggage or cargo there are more ULD to be stored.

 

ULD and Storage

Storing ULD is a well-known problem that impacts just about every sector of the air cargo industry. Airlines, ground handlers, cargo terminals and freight forwarders are all likely to have to manage to store more ULD than they have the capability for from time to time. Airports do in most cases operate within fixed boundaries, yes a few have the luxury of abundant real estate that is not taken up by car parks etc., but for most it’s a challenge to fit a “quart into a pint pot”. Regrettably, ULD are often well down the food chain, left to find a place to rest after all the other aircraft, vehicles and GSE are allocated their requirements and this has a serious impact.

The IATA Airport Handling Manual which can be considered as the industry benchmark for all operational standards devotes an entire section- AHM 421- Storage of Unit Load Devices- to this subject. Furthermore, the IATA Standard Ground Handling Agreement contains the following wording:

6.3 Unit Load Device (ULD) Control

6.3.1

(a) Provide

(b) Arrange for storage space for

  1. passenger ULDs
  2. cargo ULDs
  3. post office mail ULDs
  4. other ULDs

which it goes without saying is very clear. While airports are not a party to the agreements between the handler and the airlines it nevertheless is logical that as part of their separate contractual arrangements with their tenant handlers they respect the needs of the ground hander, failure to acknowledge that ULD require sufficient storage space will in the longer run lead to poor operational safety and efficiency, which is not desirable for any of the stake holders

ULD storage can be split roughly between those used for passenger baggage and those for cargo operations, and the involvement of the airport is different for each of these:

Passenger baggage operations require that ULD be stored in the immediate vicinity of the baggage operations, typically close to the baggage handling areas. It may even be possible that ULD never need to leave the dolly, as they are emptied from one flight and go direct to reloading for another flight. However sufficient storage is essential, and this storage needs to be properly managed, common ULD storage racking areas are likely to become problematic. As these storage areas are typically outdoors they need to be protected against wind and jet blast as well as having easy access for brining ULD in and out.

 

Cargo operations are somewhat different. First of all the storage must handle both pallets and also full width and maybe full height main deck ULD, this of course adds to complexity and volume requirements. Secondly cargo, with its much greater unpredictability requires a greater security stock of ULD, which of course need storage. And then there the special items, horse stalls, 20 ft. pallets, Temperature Controlled ULD, vehicle racks, all of which require suitable storage. On the other hand, a cargo terminal typically has control over its own “footprint” and can therefore establish suitable ULD storage from its own resources.

 

It’s one thing to have suitable storage, and it’s quite another to have it used correctly. A ULD on the ground is always a ULD at risk of damage, either by being hit by GSE etc. or during the transition from dolly to ground and back up. Airports do impose multiple rules on their operators and banning any ULD being left on the tarmac should always be a “NO GO” scenario.

 

Airports and ULD

What can the owners of ULD do about this? Well, it’s a slow process, but as with any change you need to start somewhere. ULD Explained is a great tool to educate airports as to the importance and needs of ULD, so one place to start is to introduce this solution to your local airport authority, it’ll probably be the first time anyone provided them with any kind of educational material on ULD.
