1. A method for ensuring aerodynamic continuity of an upper surface of an aircraft wing between a spoiler in a spoiler retracted
position and a trailing edge flap in at least one flag deployed position,
said spoiler being able to assume either (i) said spoiler retracted position in which said spoiler is housed in said upper
surface thereby ensuring the aerodynamic continuity of said upper surface or (ii) at least one spoiler deployed position in
which said spoiler protrudes with respect to said upper surface by being inclined with respect to said upper surface,
said trailing edge flag being able to assume either (i) a flap retracted position in which said trailing edge flag is in aerodynamic
continuity with said upper surface and with a lower surface of said wing of which said trailing edge flag forms a part of
the trailing edge or (ii) said at least one flag deployed position, deflected with respect to retracted position, causing
a protrusion on the upper surface and a hollow on the lower surface of said wing;
the disposition of said spoiler and of said trailing edge flap being such that the trailing edge of said spoiler in the spoiler
retracted position bears on said trailing edge flap in the flap retracted position, wherein, when said trailing edge flap
is in said at least one flag deployed position whilst said spoiler is in the spoiler retracted position, the length of said
spoiler is increased in a direction parallel with its chord in such a way that the trailing edge of said spoiler advances
toward said trailing edge flap and comes to bear on the upper surface of the latter, in order to compensate for the break
in aerodynamic continuity caused by the deployment of said trailing edge flap.
