The Fixed-Type Underground GPU/PCA system is an advanced method for supplying electricity and air-conditioned air to parked aircraft. It is designed to replace conventional Auxiliary Power Units (APUs), aligning with global efforts to reduce CO2 emissions and improve airport operational efficiency. This technology is recognized as a superior and environmentally friendly solution developed in Japan.

Purpose
The primary objective of this system is to provide parked aircraft with a stable and efficient source of electrical power and air conditioning without relying on APUs, which contribute significantly to CO2 emissions. By embedding the system underground, it enhances safety, efficiency, and aesthetics at airport aprons.

Features
• Eco-Friendly: Reduces CO2 emissions to approximately 1/10 of those generated by APUs.
• Safety Improvement: Eliminates the risk of accidental contact by removing the need for mobile supply vehicles.
• Operational Efficiency: Provides a quicker connection time compared to mobile units.
• Aesthetic Enhancement: The underground installation prevents obstruction and preserves apron landscapes.
• Durability: Embedded pipes have long-lasting usability, almost perpetual in operation.
• Energy Efficiency: The conditioning air supply is less affected by external temperatures, improving energy conservation.

Effects and Advantages
• Environmental Benefits: Supports CO2 reduction policies and aligns with global sustainability efforts.
• Enhanced Safety: Reduces the presence of ground vehicles, lowering accident risks.
• Improved Airport Operations: Faster connection times contribute to smoother aircraft servicing.
• Infrastructure Longevity: Durable underground components reduce the need for frequent replacements or maintenance.
• Better Airfield Aesthetics: Removes visible clutter from the apron area, improving the airport’s overall appearance.

The Fixed-Type Underground GPU/PCA system is installed in multiple Japanese airports, with approximately 600 units deployed across nine airports.

This system exemplifies Japan's technological innovation in the aviation industry, contributing to more sustainable and efficient airport operations.

Unlike general human waste, aircraft sewage is mixed with antimicrobial agents, coloring agents, and in cold regions, anti-freeze solution to prevent freezing. In addition, various treatments are required, such as separation and disposal of contaminants and paper in sewage, prevention of pathogens such as infectious diseases, decolorization, and deodorization. Therefore, we perform advanced treatment to remove nitrogen and phosphorus and dilute and sterilize sewage in consideration of the environment, and treat it to a level that meets sewer discharge standards at our facility.

1. Efficient refueling: By pumping aviation fuel through underground pipes directly underneath the aircraft, the use of refueling tankers can be reduced and refueling can be completed quickly. In addition, after aviation fuel is transported by sea, large amounts of fuel can be refueled safely and quickly.
2. Improved safety: Using underground piping reduces the risk of accidents caused by aboveground fuel transportation and increases safety.
3. Reducing environmental impact: Reduces carbon dioxide emissions emitted by fuel tanker trucks, reducing the burden on the environment.

R-EMS is the solution to support airport environmental department to manage environmental noise assessment.
The evaluation of noise exposure situation around airports throughout the year will be beneficial for environmental assessment and countermeasures against aircraft noise.
Flight tracking information can also be useful to consider flight times and flight routes.
"Publication portal website which can introduce environmental measures, noise monitoring, and other initiatives being implemented by the airport.
Real-time publication of noise and flight-track information on the map is visually explanatory and will greatly contribute to building trust with residents."

Features:
・Acquire aircraft noise report with detailed aircraft information.
Observe flight tracking data using ADS-B and PSSR even in situations where radar data from airport cannot be provided.
・PSSR (Passive Secondary Surveillance Rader) is RION's unique technology, which can observe flight-tracking information for all aircraft including one without ADS-B.
・Sound Arrival Direction information can identify the noise events even when there are large noise sources other than aircraft nearby, or when it is difficult to identify noise events by flight tracks.
・Special microphone with excellent weather resistance, allowing accurate measurements even in the rainy and humid climate.

Modern airports handle hundreds of thousands oflandings and take offs annually. The high demand would require very precise airport operation to be carried out at a rapid pace. Aviation needs to adapt to the changing nature of risks since new risks could arise anytime which requires advancements in the airport safety and security efforts. One of the most critical airport’s safety risk is the presence of foreign object debris on the runaways. Kokusai Denki’s solution to this problem is its state-of-the-out Linear Cell Radar System Technology. It is a monitoring system that has the capability to detect foreign objects on the runway at a fast speed, supported with an automatic alert mechanism. We support airport operation with superior radar performance of unprecedented detection speed.

The energy center supplies each consumer with steam produced in a boiler as a heat source. To ensure stable boiler operation and steam quality, 3-5% of steam is discharged through a continuous blower. The aim is to reduce CO2 emissions by recovering heat from this continuous blower and adding it to the boiler feedwater, thereby reducing the amount of steam used to preheat the feedwater.

Characteristics: Currently, continuous blowing is treated as wastewater. By installing a heat recovery heat exchanger, the heat from continuous blowing (approximately 180℃) can be effectively recovered continuously.

Effect: CO2 reduction of approximately 200t-CO2/year.
