If a pilot experiences a failure in a primary flight display, what should they do?

The situation described involves a primary flight display failure, which can significantly impact a pilot's ability to navigate and control the aircraft safely. The requirement to notify the National Transportation Safety Board (NTSB) is rooted in the regulations governing aviation safety and reporting procedures.

When a significant malfunction occurs, such as the failure of a primary flight display, pilots are required to evaluate the situation and take appropriate action. This includes notifying the NTSB if the malfunction leads to or could lead to safety of flight concerns. The NTSB requires reports on any incident that could pose a risk to aviation safety, regardless of whether the conditions are visual meteorological conditions (VMC) or instrument meteorological conditions (IMC). This helps ensure that the relevant authorities can investigate the occurrence and implement any necessary safety measures or changes to practices or regulations to prevent future incidents.

In contrast, other options suggest various responses that do not align with the focus on safety and protocol. Continuing to fly without notifying anyone neglects the need for safety reporting and could exacerbate the situation. Checking for backup displays is a prudent step, but it should be accompanied by notifying authorities, as the failure could have broader implications. Waiting until landing to assess the situation does not prioritize the urgent need for
