POROSITY:
Porosity is measured with a calibrated Porosimeter. It should be measured in at least 5 different places on the upper surface. Below is
an example of the sections we test at Apco. The upper surface, at 20-35% chord (from L/E) is most prone to becoming porous, and is
thus the most important section to test. It is also important to test the different cloth types, and different colours used.
LINE MAINTENANCE
Superaramide lines are known to be sensitive to the influence of the elements. They must be carefully inspected periodically. In his/her
own interest, the pilot must observe the following points to ensure maximum performance and safety from the glider. Avoid sharp
bending and squeezing of lines. Take care that people do not step on the lines. Do not pull on the lines if they are caught on rocks or
vegetation. Avoid getting the lines wet. If they do get wet, dry them as soon as possible at room temperature and never store them wet.
One line of each line group (a, b, c, upper and lower) must be tested for minimum 50% of the rated strength. if the line fails under the
load test or does not return to its specified length all the corresponding lines must be replaced. never replace lines with different
diameter or type of lines as all gliders were flight and load tested for safety in their original configuration. Changing line
diameter/strengths can have dangerous / fatal consequences.
Professional use of gliders: towing, tandem, schooling and competition flying requires more frequent line inspection and replacement of
A, B, C, D and brake lines.
For replacement lines please refer to our online direct line services.
