At airports where weather services are not available, the approach may be initiated and a landing executed if, when reaching the MDA or DH, the weather is found to be at or greater than that specified for the approach. Department pilots shall not operate an aircraft below the authorized MDA or continue an approach below the authorized DH unless: The aircraft is continuously in a position from which a descent to a landing on the intended runway can be made at a normal rate of descent using normal maneuvers, unless that descent rate will allow touchdown to occur within the touchdown zone of the runway of intended landing. The flight visibility is not less than the visibility prescribed in the standard instrument approach procedure being used. Where any necessary visual reference requirements are specified by the FAA Administrator, at least one of the following visual references for the intended runway is distinctly visible and identifiable to the pilot: A. The approach light system, except that the pilot may not descend below 100 feet above the touchdown zone elevation using the approach lights as a reference unless the red terminating bars or the red side row bars are also distinctly visible and identifiable. B. The threshold. C. The threshold markings. D. The threshold lights. E. The runway end identifier lights (REIL). NBAA Safety Best Practices

CIRCLING APPROACHES Department fixed-wing aircraft will be operated to Category D weather minimums during circling approaches. If, in the case of some international airports, Category D minimums are not listed then the criteria for Category C minimums will be used during circling approaches. BRAKING ACTION REQUIREMENTS Aircraft operated by the Department shall not takeoff or land on runways that are covered with ice or snow unless a runway condition/braking action report can be obtained prior to operation. The PIC operating at airports where ice or snow covered runways are reported, or anticipated, must obtain runway condition reports and braking action reports, prior to operating at those airports. A braking action report must be evaluated with regard to its source, timeliness and changes to be expected with fluctuations in temperature. The reported braking action must be better than nil. Braking action reports of “fair or poor” are acceptable if the runway is into the wind and equals or exceeds the landing field requirement or the balanced field length requirement as defined in the airplane flight manual. Extreme caution should be exercised under these conditions. The PIC’s judgment shall always be the determining factor.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
