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.
Letâs say the attic is 2,000 square feet (40 ft. length. x 50 ft. width attic floor space). Hereâs how the code minimum of 1/150. (1 sq. ft. of NFA for every 150 sq. ft. of attic floor space) looks on paper. step one: Determine the total NFA needed for the attic.
