If its the concorde you are referring to then the drooped nose would provide:
(a) Better visibility for the pilot on approach due to the higher attitudes of delta plan form aircraft on finals, especially in case of partial or flapless landing.
(b) The camber of the nose provides some degree of fuselage created lift. Esp on approach.
(c) The nose oleo would be excessively long if the nose was not drooped, which would cause very poor ground handling including braking.
Thats all I can think of just now
Open to corrections
