SECTION XI
AERIAL NAVIGATION
Allied aircraft in German territory.
Aircraft of the allied and associated powers shall have full liberty of passage and landing over and in German territory, equal treatment with German planes as to use of German airdromes, and with most favored nation planes as to internal commercial traffic in Germany. Germany agrees to accept allied certificates of nationality, airworthiness, or competency or licenses and to apply the convention relative to aerial navigation concluded between the allied and associated powers to her own aircraft over her own territory. These rules apply until 1923, unless Germany has since been admitted to the League of Nations or to the above convention.
