Zurich, Switzerland (July 28, 2021): Switzerland-based aviation technology company, Assaia International AG, presented findings from two deployments of the ApronAI system, one at a medium-sized European and one at a large US airport.
The system is used for turnaround control and provides a real-time overview of the current situation in the airport’s operations control centre (AOC). The operators in the AOC can see, in real-time, when an aircraft parked and receive notifications if the GPU is not connected within 3 or 4 minutes after aircraft parking. This is important as it is directly linked to the amount of CO2 emitted into the atmosphere.
Real-time insight into Ground Power Unit (GPU) connections and off-block time predictions allow performing GPU connections quicker after arrival and disconnections closer to the actual off-block time (AOBT). Quicker connections and disconnections means that the aircraft’s Auxiliary Power Unit (APU) can be turned off earlier and/or turned on later which leads to fuel savings. These, in turn, result in cost savings and most importantly, a substantial reduction in CO2 emissions.

in GPU connection and disconnection times.
On a per-flight basis, these figures might not look very spectacular but If we take the average savings between the US and European airport, the annual global savings potential from better GPU operations adds up to 650 million kilograms of kerosene savings, $500 million in fuel cost savings and a staggering 2 billion kilograms of CO2 emission reduction.
Sustainability is one of the major strategic topics for airports and airlines. Often, it is directly tied to either their license to operate and/or pre-condition for further growth. Even though the aviation industry has been hit very hard by the COVID crisis, all major aviation stakeholders have confirmed their ambitions to become carbon neutral by 2050.
These ambitions obviously demand airports and airlines to make changes to the way they run their operations. Investments in smart technologies can help to achieve different, more sustainable, operational outcomes.

PAVIX: Proven Winner for All Airport Concrete Infrastructure
International Chem-Crete Corporation (ICC) manufactures and sells PAVIX, a unique line of crystalline waterproofing products that penetrate into the surface of cured concrete to fill and seal pores and capillary voids, creating a long lasting protective zone within the concrete substrate.
Once concrete is treated, water is prevented from penetrating through this protective zone and causing associated damage, such as freeze-thaw cracking, reinforcing steel corrosion, chloride ion penetration, and ASR related cracking.
This white paper discusses how the PAVIX CCC100 technology works and its applications.
