1 Left and Right Wing Leak Message

2  In high temperatures, there is a high frequency and instances of “nuisance messages”. This is caused by hot air in the pack bays that cannot escape, and the A and B loops detect overheat.  The APU bleed and packs shut down, followed by master caution faults. These include Upper and lower Ecam, left or right wing leak message, APU bleed fault, pack fault associated with overhead panel, engine bleed fault, and pack fault.

11  The proposed Connector will correct the issues indicated by these “nuisance messages”, and provide further relief in the following ways:  The connector hooks up to the Huffer connection, where it will allow cool air to flow into the pack bays, and not into the bleed system  The packs are then able to work more efficiently, keeping the passengers, flight crew, and cabin cool.  Instead of being a reaction, the connector is a proactive solution to prevent these problems from happening during quick turns

18  Resetting Engine 1 and 2 bleed switches  Resetting flight warning computer 1 and 2 circuit breakers  In accordance with TSM  Connecter will prevent these problems, given there are no pre-existing issues such as a pack bleed leak; in which case the messages will not clear unless problem parts are repaired or replaced per the TSM

23  Using this connector during quick turns (ie. 30, 45, 60 minutes), the aircraft will be using no extra fuel while still keeping the aircraft cool and preventing “nuisance messages” and their indications.

24  Connector allows packs to function more efficiently, creating conditions similar to cooler temperatures and/or cruising altitude.  Passengers and Flight Crew are kept in cooler and more comfortable conditions while boarding and before takeoff on Flight line  Given the mechanical advantages provided by a more efficient cooling system (connector), flights in hot climates or conditions worldwide will experience less delays and/or cancellations due to overheating as indicated by ”nuisance messages”

25  Using the connector will prevent billions in revenue loss worldwide by:  Reducing flight delays due to prevention of “nuisance messages” caused by overheating  Reducing cancellations  Reducing the need for preventative maintenance  Increasing customer satisfaction All of the above translate ultimately to increasing revenue for all parties involved.
