Under what condition may pilots take off when weather is below landing minimums?

Pilots may take off when weather is below landing minimums only if they have specific authorization from the applicable Major Command (MAJCOM). This requirement is in place to ensure that safety protocols are strictly followed, as flying under such conditions can pose significant risks to the aircraft and crew if appropriate measures and training have not been completed.

This authorization signifies that the flight has been properly assessed and deemed necessary under exceptional circumstances, while ensuring that the appropriate contingency plans are in place. Such measures are critical, as they help to mitigate risks that come from reduced visibility or adverse weather conditions.

In contrast to the other options, which do not establish formal protocols or assurances specific to flying below minimums, the requirement for MAJCOM authorization adds a layer of oversight and responsibility to the decision-making process for pilots. Consequently, only a higher authority like MAJCOM can evaluate if the situation warrants such a departure from standard operating procedures.
