Prior to Flight Takeoff Alternate Required [§135.217] If weather above takeoff minimums but below authorized IFR landing minimums must have an alternate airport within 1 hour's flying time (at normal cruise speed in still air) of the departure airport. Destination Alternate Not Required [§91.167] — If there is an IAP and weather for ETA +/- 1 hour is at least 2,000 and 3. Destination Alternate Not Required [§135.223] — If there is an IAP AND Weather for ETA +/- 1 hour at least 1,500' ceiling above lowest circling MDA or if no circling at least 1,500' above lowest minimum or 2,000' above airport elevation whichever higher AND Visibility at least 3 miles or 2 miles more than lowest applicable mins, whichever greater. Approach Minimums [§91.175] — (b) For the purpose of this section, when the approach procedure being used provides for and requires the use of a DA/DH or MDA, the authorized DA/DH or MDA is the highest of the following: (1) The DA/DH or MDA prescribed by the approach procedure. (2) The DA/DH or MDA prescribed for the pilot in command. (3) The DA/DH or MDA appropriate for the aircraft equipment available and used during the approach. Alternate Airport Weather Requirements [§91.169] — With IAP: 600'/2 precision, 800'/2 non precision at ETA Without IAP: ceiling and vis to allow descent from MEA, approach and landing under basic VFR. Prior to Takeoff Minimum Fuel [§91.151] — No person may begin a flight in an airplane under VFR conditions unless (considering wind and forecast weather conditions) there is enough fuel to fly to the first point of intended landing and, assuming normal cruising speed (1) During the day, to fly after that for at least 30 minutes; or (2) At night, to fly after that for at least 45 minutes. Minimum Fuel [§91.167] — No person may operate a civil aircraft in IFR conditions unless it carries enough fuel (considering weather reports and forecasts and weather conditions) to (1) Complete the flight to the first airport of intended landing; (2) Except when an alternate is not required, fly from that airport to the alternate airport; and (3) Fly after that for 45 minutes at normal cruising speed or, for helicopters, fly after that for 30 minutes at normal cruising speed. Takeoff Minimums [§91.175] — As provided in Part 97, if none then 1 sm visibility for 2 engine aircraft.
