906.7 DESCRIPTION OF THE SYSTEM
Wing tank:
The leading edge section of each wing in front of main spars forms an integral fuel tank
providing two interconnected tanks with 154 litres (40,7 US GAL.) total capacity. Each side
of the wing has a 2" diameter filler cap for gravity refuelling. The long range tank has two
compartments in either wing which are separated by a slosh rib. Due to the interconnection
the fuel level of the left and right integral tank will equalize during refuelling within reason-
able time. For max. fuel capacity, the first filled side have to be filled once again!
The wing tank can be completely emptied in flight.
