Supplemental operations.

    (a) Except as provided in paragraph (b) of this section, no person 
may release for flight or takeoff a nonturbine or turbo-propeller-
powered airplane unless, considering the wind and other weather 
conditions expected, it has enough fuel--

    (2) Thereafter, to fly to and land at the most distant alternate 
airport specified in the flight release; and
    (3) Thereafter, to fly for 45 minutes at normal cruising fuel 
consumption or, for certificate holders who are authorized to conduct 
day VFR operations in their operations specifications and who are 
operating nontransport category airplanes type certificated after 
December 31, 1964, to fly for 30 minutes at normal cruising fuel 
consumption for day VFR operations.
    (b) If the airplane is released for any flight other than from one 
point in the contiguous United States to another point in the contiguous 
United States, it must carry enough fuel to meet the requirements of 
paragraphs (a) (1) and (2) of this section and thereafter fly for 30 
minutes plus 15 percent of the total time required to fly at normal 
cruising fuel consumption to the airports specified in paragraphs (a) 
(1) and (2) of this section, or to fly for 90 minutes at normal cruising 
fuel consumption, whichever is less.
    (c) No person may release a nonturbine or turbo-propeller-powered 
airplane to an airport for which an alternate is not specified under 
Sec. 121.623(b), unless it has enough fuel, considering wind and other 
weather conditions expected, to fly to that airport and thereafter to 
fly for three hours at normal cruising fuel consumption.
