# Airline and VIP Configurations: Results Comparison

The Article #3 shows the Small Volume Decompression analysis and results of a Cabinet installed in the Airline/PAX Configuration of Numeric Corporate Jet.

The Article #4 shows the Small Volume Decompression analysis and results of a Cabinet installed in one of the rooms of the Numeric Corporate Jet considering the VIP Configuration.

The graph below compares the results considering both configurations: Airline/PAX and VIP.

The Table below shows the results difference ($\Delta_P {VIP} - \Delta_P {PAX}$).

# Conclusion

The table above shows that the results difference ($\Delta_P {VIP} - \Delta_P {PAX}$) is positive in the most of it. A positive result difference means that a same Cabinet is exposed to higher $\Delta_P$ when installed in VIP configuration than in PAX configuration.

In addition to that, some of the results difference ($\Delta_P {VIP} - \Delta_P {PAX}$) shown in the table above are negative. It means that a same Cabinet will experience higher $\Delta_P$ when installed in PAX configuration than in VIP configuration.

Generally one can expect that a Cabinet installed in VIP configuration (enclosed in smaller room) should withstand higher $\Delta_P$ than when installed in PAX configuration (enclosed in bigger room - Main Deck). HOWEVER as shown by the table above, this conclusion can not be generalised! In other words, based on the table above, we can conclude that the size of the room where the Cabinet is enclosed is not the only factor that need to be considered here. We will step forward with additional explanations in the next Article. Stay tuned!

It is also important to highlight that normally the Small Volumes Decompression provided by the manufactures (OEM) consider the Airline/PAX Configuration as default. It means that those $\Delta_P$ may not cover the actual values sustained by Cabinets when installed in another configuration (as per all positive results difference in the table above).

In any case, Esonix is an easier and efficient tool to investigate how the decompression sustained by a Cabinet/Compartment is affected due the interior refurbishment.

## NEXTSTEP…

In the next Article, we will investigate and explain the negative values shown in the Table above (Cabinet Volume between 75-150ft³ and Vent Area between 1-4in²). Those negative values demonstrate that the $\Delta_P$ in PAX configuration is “unexpected” higher than the $\Delta_P$ in VIP configuration.
