91.405 IFR alternate aerodrome requirement

(A) A pilot-in-command of an aircraft operating under IFR must list at least 1 alternate aerodrome in the flight plan unless—

(1) the aerodrome of intended landing has a standard instrument approach procedure published in the applicable AIP; and

(2) at the time of submitting the flight plan, the meteorological forecasts indicate, for at least 1 hour before and 1 hour after the estimated time of arrival at the aerodrome of intended landing, that—

• the ceiling at the aerodrome will be at least 1000 feet above the minimum published in the applicable AIP for the instrument procedure likely to be used; and
• visibility will be at least 5 km, or 2 km more than the minimum published in the applicable AIP, whichever is the greater.

(B) A pilot-in-command of an aircraft must not list any aerodrome as an alternate on the IFR flight plan under paragraph (a) unless the meteorological forecasts at the time of submitting the flight plan indicate that, at the estimated time of arrival at the alternate aerodrome, the ceiling and visibility at that aerodrome will be at or above the following meteorological minima—
