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)

Reduced air & noise

pollution

Improved cabin

thermal comfort

Shorter turnaround

time

Lower operational

costs for airlines

New revenue

stream for airlines

Pre-conditioned Air (PCA) – New market players, new challenges


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

Traditional aviation markets

New mid-end markets (15 years)

New high-end markets (10 years)

Extreme temperature, humidity and VLA

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

Cavotec’s AHM997 PCA Timeline – In operation

Starting in 2005, Cavotec had launched a Subfreezing PCA R&D program.

Emirates Airline asked Cavotec to help them.

The project was initiated and a cooperation with Airbus started.

Cavotec makes successful test lab demonstration of Subfreezing PCA for Airbus

Cavotec makes Subfreezing aircraft ground cooling tests at Airbus in Toulouse.Aircraft tested: A320, A340-600 and A380-800

Cavotec makes Subfreezing aircraft ground cooling tests in Dubai. The test is attended and supported by Airbus. Aircraft tested: A330-200, A340-500, B777-300

• 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
