What landing minimums apply at an alternate airport during an instrument approach?

The minimums published for the procedure selected are the correct option because these specified minimums provide the required visibility and/or cloud clearance necessary for a safe approach and landing at the alternate airport during an instrument flight. Each approach procedure in the FAA's approach plates includes specific minimums based on the aircraft category, runway conditions, and obstacles in the vicinity. These published minimums ensure that pilots have the necessary guidance to determine if they can safely execute the approach based on current weather conditions and other factors.

Understanding that standard landing minimums may vary from those published for specific approaches is crucial, as they often take into account the peculiarities of each procedure, including the type of approach (precision or non-precision), as well as the equipment capabilities of the aircraft. The lowest available minimums are typically not a predefined safe choice, as they can refer to various factors not directly tied to the approach procedure, thus creating potential confusion. Visual flight rules minimums are irrelevant in this context since the question specifically pertains to instrument approaches, where adherence to instrument approach minimums is mandatory.
