Weight: The LiteAir Window Plug weighs 1.3 lb. The LiteAir Window Seal weighs 0.6 lb.

Installation: The LiteAir Window Plug and seal is installed per LiteAir’s STC. The STC installs the components per the OEM Maintenance Manual using the existing retaining method.

Maintenance: Visual Inspection at each fourth ‘C’ check. The STC allows for component repair.


Advantages – A300

Weight: The weight of the LiteAir Window Plug installation is 2.5 pounds less (per window) than the OEM acrylic window installation. This can produce more than 250 pounds saving per airplane. The lightweight Window Plug installation includes a LiteAir Seal which eliminates the need for the installation of the acrylic Middle Pane or Spacer Rings.

Fuel Saving: At today's fuel prices the window plug installation can pay for itself under three years.

Maintenance: The acrylic windows require inspection approximately every 3 years which can result in 25% of the windows being serviced or replaced. The Window Plug and Spacer Ring require a visual inspection every six years with likely no service or replacement.

Easy Installation: Simple as replacing a window. STC certified

Parasitic Drag: The deflection of the Window Plug under pressure is approximately 0.18 inches while the OEM acrylic window deflects 0.43 inches. Consequently the window plug produces less parasitic drag.

Aesthetics: A fully “plugged” freighter is aesthetically more pleasing

Painting: A fully plugged freighter is much easier, and consequently less expensive to
paint. Note, some converted freighters have painted over windows and window failures have resulted owing to an adverse reaction between the paint and the acrylic.
