4. Pre-conditioned Air (PCA) - Key benefits
PCA is an external ground service enabling aircrafts to be cooled on ground without the use of the Auxiliary Power Unit (APU)
Improved cabin thermal comfort
Reduced air & noise pollution
Shorter turnaround time
Lower operational costs for airlines
New revenue stream for airlines

5. Pre-conditioned Air (PCA) – New market players, new challenges
Traditional aviation markets
New mid-end markets (15 years)
New high-end markets (10 years)
High humidity
Extreme temperature, humidity and VLA
High humidity
Bigger aircrafts, more modern with multiple on-board equipments and operated in hot ambient conditions are challenging the industry in engineering higher PCA cooling performance systems

6. Pre-conditioned Air (PCA) – Industry standards
As a result, airlines and aircraft manufacturers have been looking for higher PCA cooling performance and the industry had to create a new standard with the AHM997

25. Cavotec’s PCA systems – Conclusion
SUBFREEZING, GOING BEYOND THE HORIZONS
Cavotec has been able to initiate the definition and adoption of a new cooling method and standard
Aircrafts being bigger and more equipped and operated in severe ambient conditions require the AHM997 as a standard method for an efficient aircraft cooling and under all conditions
Safety features are critical - a permanent control of the PCA flow and pressure is a must and shall not be neglected
The subfreezing has to be engineered as a complete system for maximizing its performance and reducing the potential design liability risks
