be taken at the airport where those
IFR operations are conducted, unless
the Administrator issues operations
specifications allowing the use of
weather observations taken at a location not at the airport where the IFR
operations are conducted. The Administrator issues such operations specifications when, after investigation by
the U.S. National Weather Service and
the responsible Flight Standards office,
it is found that the standards of safety
for that operation would allow the deviation from this paragraph for a particular operation for which an air carrier operating certificate or operating
certificate has been issued.

Section 135.215

IFR: Operating limitations.

(a) Except as provided in paragraphs
(b), (c) and (d) of this section, no person
may operate an aircraft under IFR outside of controlled airspace or at any
airport that does not have an approved
standard instrument approach procedure.
(b) The Administrator may issue operations specifications to the certificate holder to allow it to operate under
IFR over routes outside controlled airspace if - 
(1) The certificate holder shows the
Administrator that the flight crew is
able to navigate, without visual reference to the ground, over an intended
track without deviating more than 5
degrees or 5 miles, whichever is less,
from that track; and
(2) The Administrator determines
that the proposed operations can be
conducted safely.
(c) A person may operate an aircraft
under IFR outside of controlled airspace if the certificate holder has been
approved for the operations and that
operation is necessary to - 
(1) Conduct an instrument approach
to an airport for which there is in use
a current approved standard or special
instrument approach procedure; or
(2) Climb into controlled airspace
during an approved missed approach
procedure; or

(3) Make an IFR departure from an
airport having an approved instrument
approach procedure.
(d) The Administrator may issue operations specifications to the certificate holder to allow it to depart at an
airport that does not have an approved
standard instrument approach procedure when the Administrator determines that it is necessary to make an
IFR departure from that airport and
that the proposed operations can be
conducted safely. The approval to operate at that airport does not include an
approval to make an IFR approach to
that airport.
Section 135.217 IFR: Takeoff limitations.
No person may takeoff an aircraft
under IFR from an airport where
weather conditions are at or above
takeoff minimums but are below authorized IFR landing minimums unless
there is an alternate airport within 1
hour-s flying time (at normal cruising
speed, in still air) of the airport of departure.
Section 135.219 IFR:
Destination
airport
weather minimums.
No person may take off an aircraft
under IFR or begin an IFR or over-thetop operation unless the latest weather
reports or forecasts, or any combination of them, indicate that weather
conditions at the estimated time of arrival at the next airport of intended
landing will be at or above authorized
IFR landing minimums.
Section 135.221 IFR: Alternate airport weather minimums.
(a) Aircraft other than rotorcraft. No
person may designate an alternate airport unless the weather reports or forecasts, or any combination of them, indicate that the weather conditions will
be at or above authorized alternate airport landing minimums for that airport at the estimated time of arrival.
(b) Rotorcraft. Unless otherwise authorized by the Administrator, no person may include an alternate airport in
an IFR flight plan unless appropriate
weather reports or weather forecasts,
or a combination of them, indicate
that, at the estimated time of arrival
at the alternate airport, the ceiling
and visibility at that airport will be at
