I know the general requirements for asking for a visual approach:
a) the Met reported ceiling is at or above the published initial approach level for the aircraft so cleared; or
b) the pilot reports at the inital approach level or at any time during the instrument approach procedure that the meteorological conditions are such that with reasonable assurance a visual approach and landing can be completed.
No minimum visibility is stated;but once i heard about a visibility of 800 meters, minimum, to request a visual app.
Are you aware of any visibility limitation by regulation?
Any help appreciated
