  • Freighter conversions

    Hey y'all

    I have just finished my 2nd year of a degree in aerospace engineering and have been wondering why frieght convertors put in a some sort of wall so that you can't see in through the windows? Do they remove the shades aswell and keep this inner wall? Is there any kind of structural/weight benefit?

    Thanks
    Jay

    In most cases windows are removed and replaced with metal plugs shaped kind of like a window. Windows are a maintennance items that needs to be checked/replaced periodically. No windows...no inspections/replacements...saves $.

      So the perspex is removed and metal plugs slot right in?

      Doesn't this cost quite a lot and add weight?
      Is it really faster to check metal plugs than to check the windows?
      Thanks

        The full up P to F (Passenger ti Freighter) process involves stripping the entire passenger cabin to the bare walls. A hole is cut in the fuselage and the cargo door is installed. Replacement of all cabin floor boards, replacement of all cabin floor support beams, installation of flame resistant cabin and cockpit insulation, replacement of the cabin windows with aluminum plugs, installation of "PLYON" covering the cabin walls, Installation of the cargo loading system.

        Floor boards and support beams are replaced with stronger units. "PLYON" replaces the sidewall panels installed in the PAX aircraft (weight issue) Windows are replaced with plugs (weight issue). Metal plugs are about 1/2 the weight of the plexiglass windows.

        The empty weight of the converted freighter is very close to the empty weight of the PAX aircraft.

        The process takes 80 - 90 days for most aircraft.

          Not doubting the master Don, but isn't there a change in the inspection frequency? I always thought that the plugs were install and forget.
