Dear subscribers,

 

My ac unit uses an air intake on the bottom of the fuselage – it is a rectangular hole with approx 8”x1.5”.

 

On my tail I have another air intake which is not connected to a hose. It just lets air (and dirt – everything was pretty dusty back there) in the back of the fuselage. The area of the hole in the bottom of the fuselage is approx. 2.5 x bigger than the area of the air inlet in the tail. My heat exchanger for which the air intake is used has an area of approx 15” x 10”. A big fan forces the air through the heat exchanger.

 

I assume that the air intake in the tail is originally designed to be used for the ac unit and that the previous owner cut a hole in the bottom of the fuselage to force more air through the heat exchanger of ac unit. I want to close the hole in my tail now since I am not using this air intake.

 

Would you recommend my plan or does the air intake in the tail serve another purpose?

 

Thank you for your help
