What is the size of the standard storage tube for the oxygen cylinder?
The standard O2 storage tube is located in the fuselage center section behind the pilot’s right elbow. Gliders up to serial number 015 accept a Mountain High AL-180 cylinder or an Aerox AV54G cylinder. Gliders from serial number 016 accept a Mountain High AL-248 or Aerox CV54G in the standard storage tube. A regulator with “radial” (as opposed to “axial”) outlet is recommended.
