§ 135.225 IFR: Takeoff, approach and landing minimums. ( a ) Except to the extent permitted by paragraphs (b) and (j) of this section, 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 ) A pilot conducting an eligible on-demand operation may begin and conduct an instrument approach procedure to an airport that does not have a weather reporting facility operated by the U.S. National Weather Service, a source approved by the U.S. National Weather Service, or a source approved by the Administrator if— ( 1 ) The alternate airport has a weather reporting facility operated by the U.S. National Weather Service, a source approved by the U.S. National Weather Service, or a source approved by the Administrator; and
( 2 ) The latest weather report issued by the weather reporting facility includes a current local altimeter setting for the destination airport. If no local altimeter setting for the destination airport is available, the pilot may use the current altimeter setting provided by the facility designated on the approach chart for the destination airport.
( c ) Except as provided in paragraph (j) of this section, 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.
( d ) Except as provided in paragraph (j) of this section, a pilot who has begun the final approach segment of an instrument approach to an airport under paragraph (c) of this section, and receives a later weather report indicating that conditions have worsened to below the minimum requirements, may continue the approach only if the following conditions are met— ( 1 ) The later weather report is received when the aircraft is in one of the following approach phases: ( i ) The aircraft is on an ILS final approach and has passed the final approach fix;
( ii ) The aircraft is on an ASR or PAR final approach and has been turned over to the final approach controller; or
( iii ) The aircraft is on a non-precision final approach and the aircraft— ( A ) Has passed the appropriate facility or final approach fix; or
( B ) 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; and
( 2 ) The pilot in command finds, on reaching the authorized MDA or DA/DH, that the actual weather conditions are at or above the minimums prescribed for the procedure being used.
( e ) The MDA or DA/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.
( f ) 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, unless authorized by the certificate holder's operations specifications, 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.
( g ) If takeoff minimums are specified in part 97 of this chapter for the take- off 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.
( h ) Except as provided in paragraph (i) of this section, if takeoff minimums are not prescribed in part 97 of this chapter for the takeoff airport, no pilot may takeoff 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.
( i ) At airports where straight-in instrument approach procedures are authorized, a pilot may takeoff 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.
( j ) A pilot may begin an instrument approach procedure, or continue an approach, at an airport when the visibility is reported to be less than the visibility minimums prescribed for that procedure if the pilot uses an operable EFVS in accordance with § 91.176 of this chapter and the certificate holder's operations specifications for EFVS operations.
