Aircraft fluid lines are usually made of metal tubing. or flexible hose. Metal tubing (also called rigid fluid. lines) is used in stationary applications and where long, relatively straight runs are possible. They are widely. used in aircraft for fuel, oil, coolant, oxygen, instru-. ment, and hydraulic lines. Flexible hose is generally. used with moving parts or where the hose is subject. to considerable vibration. Occasionally, it may be necessary to repair or replace. damaged aircraft fluid lines.
* Note excessive heat. If it's 90 degrees outside, the attic temperatures shouldn't exceed 110, according to home inspector Jamison Brown of AmeriSpec Home Inspection Services in Poquoson. However, more often than not, around here I find attic temperatures to be in excess of 125 on a 90-degree day, he says.
A hot roof is a properly sealed unvented attic, instead of a traditional vented roof which consist of an insulated attic floor and open soffits where air enters and then leaves through the top of the roof.pray foamed attics have foam applied directly to the roof decking, and the attic space isnât ventilated. The lack of ventilation is why they are called hot roofs. In a standard insulation system, ceiling insulation reduces the transfer of heat from the attic to the living space (in the summer).
