What is the primary concern associated with electrical disturbances during flight?

The primary concern associated with electrical disturbances during flight is instrument malfunction. In aviation, aircraft rely heavily on various instruments to provide critical information regarding altitude, speed, navigation, and overall aircraft performance. Electrical disturbances can lead to malfunctioning or failure of these instruments, which can compromise the safety and operation of the aircraft.

When instruments become unreliable due to electrical issues, pilots may lose essential data needed to navigate the aircraft safely. This can result in impaired situational awareness and increased risk during flight operations. Maintaining the proper functionality of electrical systems and instruments is crucial for ensuring a safe flying environment.

Other concerns like pilot distraction or passenger discomfort are certainly valid in the broader context of flying, but they do not have the same immediate impact on the ability to control and operate the aircraft as instrument malfunction does. Runway incursions are more related to ground operations and do not pertain directly to in-flight electrical disturbances.
