Where should fault reset procedures be performed?

The correct answer indicates that fault reset procedures should only be performed on the ground, which is crucial for ensuring safety and proper maintenance of an aircraft. Performing these procedures while on the ground allows for thorough checks and diagnostics to be conducted under controlled conditions. This is important because any faults or malfunctions can be safely assessed and resolved without the added risks associated with flying.

Additionally, performing reset procedures during critical phases of flight, such as take-off or while in-flight, could pose significant safety hazards. These scenarios require the full attention of the flight crew to manage the aircraft and respond to any emergencies. Therefore, handling fault resets on the ground minimizes risk and ensures that personnel can focus on making certain that all systems are functioning properly before the aircraft takes to the skies.
