135.203 VFR: Minimum altitudes Index

    Except when necessary for takeoff and landing, no person may operate under
  VFR--
    (a) An airplane--
    (1) During the day, below 500 feet above the surface or less than 500 feet
  horizontally from any obstacle; or
    (2) At night, at an altitude less than 1,000 feet above the highest
  obstacle within a horizontal distance of 5 miles from the course intended to
  be flown or, in designated mountainous terrain, less than 2,000 feet above
  the highest obstacle within a horizontal distance of 5 miles from the course
  intended to be flown; or
    (b) A helicopter over a congested area at an altitude less than 300 feet
  above the surface.


135.205 VFR: Visibility requirements Index

    (a) No person may operate an airplane under VFR in uncontrolled airspace
  when the ceiling is less than 1,000 feet unless flight visibility is at least
  2 miles.
    (b) No person may operate a helicopter under VFR in Class G airspace at an
  altitude of 1,200 feet or less above the surface or within the lateral
  boundaries of the surface areas of Class B, Class C, Class D, or Class E
  airspace designated for an airport unless the visibility is at least--
    (1) During the day-- 1/2  mile; or
    (2) At night--1 mile.

  

135.209 VFR: Fuel supply Index

    (a) No person may begin a flight operation in an airplane under VFR unless,
  considering wind and forecast weather conditions, it has enough fuel to fly
  to the first point of intended landing and, assuming normal cruising fuel
  consumption--
    (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.
    (b) No person may begin a flight operation in a helicopter under VFR
  unless, considering wind and forecast weather conditions, it has enough fuel
  to fly to the first point of intended landing and, assuming normal cruising
  fuel consumption, to fly after that for at least 20 minutes.

135.211 VFR: Over-the-top carrying passengers:
Operating limitations
Index

    Subject to any additional limitations in 135.181, no person may
  operate an aircraft under VFR over-the-top carrying passengers, unless--
    (a) Weather reports or forecasts, or any combination of them, indicate that
  the weather at the intended point of termination of over-the-top flight--
    (1) Allows descent to beneath the ceiling under VFR and is forecast to
  remain so until at least 1 hour after the estimated time of arrival at that
  point; or
    (2) Allows an IFR approach and landing with flight clear of the clouds
  until reaching the prescribed initial approach altitude over the final
  approach facility, unless the approach is made with the use of radar under
  91.175(f) of this chapter; or
    (b) It is operated under conditions allowing--
    (1) For multiengine aircraft, descent or continuation of the flight under
  VFR if its critical engine fails; or
    (2) For single-engine aircraft, descent under VFR if its engine fails.

135.213 Weather reports and forecasts Index

    (a) Whenever a person operating an aircraft under this part is required to
  use a weather report or forecast, that person shall use that of the U.S.
  National Weather Service, a source approved by the U.S. National Weather
  Service, or a source approved by the Administrator. However, for operations
  under VFR, the pilot in command may, if such a report is not available, use
  weather information based on that pilot's own observations or on those of
  other persons competent to supply appropriate observations.
    (b) For the purposes of paragraph (a) of this section, weather observations
  made and furnished to pilots to conduct IFR operations at an airport must 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 certificate-
  holding district 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.

135.215 IFR: Operating limitations Index

    (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.


135.217 IFR: Takeoff limitations Index

    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.



135.219 IFR: Destination airport weather minimums Index

    No person may take off an aircraft under IFR or begin an IFR or over-the-
  top 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.


135.221 IFR: Alternate airport weather minimums Index

    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.

135.223 IFR: Alternate airport requirements Index

    (a) Except as provided in paragraph (b) of this section, no person may
  operate an aircraft in IFR conditions unless it carries enough fuel
  (considering weather reports or forecasts or any combination of them) to--
    (1) Complete the flight to the first airport of intended landing;
    (2) 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.
    (b) Paragraph (a)(2) of this section does not apply if Part 97 of this
  chapter prescribes a standard instrument approach procedure for the first
  airport of intended landing and, for at least one hour before and after the
  estimated time of arrival, the appropriate weather reports or forecasts, or
  any combination of them, indicate that--
    (1) The ceiling will be at least 1,500 feet above the lowest circling
  approach MDA; or
    (2) If a circling instrument approach is not authorized for the airport,
  the ceiling will be at least 1,500 feet above the lowest published minimum or
  2,000 feet above the airport elevation, whichever is higher; and
    (3) Visibility for that airport is forecast to be at least three miles, or
  two miles more than the lowest applicable visibility minimums, whichever is
  the greater, for the instrument approach procedure to be used at the
  destination airport.

135.225 IFR: Takeoff, approach and landing minimums Index

    (a) No pilot may begin an instrument approach procedure to an airport
  unless--
    (1) That airport has a weather reporting facility operated by the U.S.
  National Weather Service, a source approved by U.S. National Weather Service,
  or a source approved by the Administrator; and
    (2) The latest weather report issued by that weather reporting facility
  indicates that weather conditions are at or above the authorized IFR landing
  minimums for that airport.
    (b) No pilot may begin the final approach segment of an instrument approach
  procedure to an airport unless the latest weather reported by the facility
  described in paragraph (a)(1) of this section indicates that weather
  conditions are at or above the authorized IFR landing minimums for that
  procedure.
    (c) If a pilot has begun the final approach segment of an instrument
  approach to an airport under paragraph (b) of this section and a later
  weather report indicating below minimum conditions is received after the
  aircraft is--
    (1) On an ILS final approach and has passed the final approach fix; or
    (2) On an ASR or PAR final approach and has been turned over to the final
  approach controller; or
    (3) On a final approach using a VOR, NDB, or comparable approach procedure;
  and the aircraft--
    (i) Has passed the appropriate facility or final approach fix; or
    (ii) Where a final approach fix is not specified, has completed the
  procedure turn and is established inbound toward the airport on the final
  approach course within the distance prescribed in the procedure; the approach
  may be continued and a landing made if the pilot finds, upon reaching the
  authorized MDA or DH, that actual weather conditions are at least equal to
  the minimums prescribed for the procedure.
    (d) The MDA or DH and visibility landing minimums prescribed in Part 97 of
  this chapter or in the operator's operations specifications are increased by
  100 feet and 1/2  mile respectively, but not to exceed the ceiling and
  visibility minimums for that airport when used as an alternate airport, for
  each pilot in command of a turbine-powered airplane who has not served at
  least 100 hours as pilot in command in that type of airplane.
    (e) Each pilot making an IFR takeoff or approach and landing at a military
  or foreign airport shall comply with applicable instrument approach
  procedures and weather minimums prescribed by the authority having
  jurisdiction over that airport. In addition, no pilot may, at that airport--
    (1) Take off under IFR when the visibility is less than 1 mile; or
    (2) Make an instrument approach when the visibility is less than 1/2  mile.
    (f) If takeoff minimums are specified in Part 97 of this chapter for the
  takeoff airport, no pilot may take off an aircraft under IFR when the weather
  conditions reported by the facility described in paragraph (a)(1) of this
  section are less than the takeoff minimums specified for the takeoff airport
  in Part 97 or in the certificate holder's operations specifications.
    (g) Except as provided in paragraph (h) of this section, if takeoff
  minimums are not prescribed in Part 97 of this chapter for the takeoff
  airport, no pilot may take off an aircraft under IFR when the weather
  conditions reported by the facility described in paragraph (a)(1) of this
  section are less than that prescribed in Part 91 of this chapter or in the
  certificate holder's operations specifications.
    (h) At airports where straight-in instrument approach procedures are
  authorized, a pilot may take off an aircraft under IFR when the weather
  conditions reported by the facility described in paragraph (a)(1) of this
  section are equal to or better than the lowest straight-in landing minimums,
  unless otherwise restricted, if--
    (1) The wind direction and velocity at the time of takeoff are such that a
  straight-in instrument approach can be made to the runway served by the
  instrument approach;
    (2) The associated ground facilities upon which the landing minimums are
  predicated and the related airborne equipment are in normal operation; and
    (3) The certificate holder has been approved for such operations.

135.227 Icing conditions: Operating limitations Index

    (a) No pilot may take off an aircraft that has frost, ice, or snow adhering
  to any rotor blade, propeller, windshield, wing, stabilizing or control
  surface, to a powerplant installation, or to an airspeed, altimeter, rate of
  climb, or flight attitude instrument system, except under the following
  conditions:
    (1) Takeoffs may be made with frost adhering to the wings, or stabilizing
  or control surfaces, if the frost has been polished to make it smooth.
    (2) Takeoffs may be made with frost under the wing in the area of the fuel
  tanks if authorized by the Administrator.
    (b) No certificate holder may authorize an airplane to take off and no
  pilot may take off an airplane any time conditions are such that frost, ice,
  or snow may reasonably be expected to adhere to the airplane unless the pilot
  has completed all applicable training as required by 135.341 and unless
  one of the following requirements is met:
    (1) A pretakeoff contamination check, that has been established by the
  certificate holder and approved by the Administrator for the specific
  airplane type, has been completed within 5 minutes prior to beginning
  takeoff. A pretakeoff contamination check is a check to make sure the wings
  and control surfaces are free of frost, ice, or snow.
    (2) The certificate holder has an approved alternative procedure and under
  that procedure the airplane is determined to be free of frost, ice, or snow.
    (3) The certificate holder has an approved deicing/anti-icing program that
  complies with 121.629(c) of this chapter and the takeoff complies with
  that program.
    (c) Except for an airplane that has ice protection provisions that meet
  section 34 of Appendix A, or those for transport category airplane type
  certification, no pilot may fly--
    (1) Under IFR into known or forecast light or moderate icing conditions; or
    (2) Under VFR into known light or moderate icing conditions; unless the
  aircraft has functioning deicing or anti-icing equipment protecting each
  rotor blade, propeller, windshield, wing, stabilizing or control surface, and
  each airspeed, altimeter, rate of climb, or flight attitude instrument
  system.
    (d) No pilot may fly a helicopter under IFR into known or forecast icing
  conditions or under VFR into known icing conditions unless it has been type
  certificated and appropriately equipped for operations in icing conditions.
    (e) Except for an airplane that has ice protection provisions that meet
  section 34 of Appendix A, or those for transport category airplane type
  certification, no pilot may fly an aircraft into known or forecast severe
  icing conditions.
    (f) If current weather reports and briefing information relied upon by the
  pilot in command indicate that the forecast icing condition that would
  otherwise prohibit the flight will not be encountered during the flight
  because of changed weather conditions since the forecast, the restrictions in
  paragraphs (c), (d), and (e) of this section based on forecast conditions do
  not apply.

135.229 Airport requirements Index

    (a) No certificate holder may use any airport unless it is adequate for the
  proposed operation, considering such items as size, surface, obstructions,
  and lighting.
    (b) No pilot of an aircraft carrying passengers at night may take off from,
  or land on, an airport unless--
    (1) That pilot has determined the wind direction from an illuminated wind
  direction indicator or local ground communications or, in the case of
  takeoff, that pilot's personal observations; and
    (2) The limits of the area to be used for landing or takeoff are clearly
  shown--
    (i) For airplanes, by boundary or runway marker lights;
    (ii) For helicopters, by boundary or runway marker lights or reflective
  material.
    (c) For the purpose of paragraph (b) of this section, if the area to be
  used for takeoff or landing is marked by flare pots or lanterns, their use
  must be approved by the Administrator.
