For an aircraft to qualify for VFR flight, which instrument is NOT required?

To qualify for Visual Flight Rules (VFR) flight, an aircraft must be equipped with certain instruments that are essential for safe navigation and operation under visual conditions. Among these, the radar altimeter is not required.

A radar altimeter measures the distance between the aircraft and the ground directly below it, providing information that is useful primarily during approaches and landings, especially in low visibility conditions. However, under VFR, pilots are primarily navigating visually and should be adequately aware of their altitude using other means.

In contrast, a magnetic compass helps in determining headings, a turn and bank indicator aids in maintaining level flight and coordination during turns, and a sensitive altimeter is crucial for accurate altitude readings—ensuring that pilots remain aware of their altitude in relation to terrain and airspace restrictions.

Because VFR flight regulations focus on ensuring pilots can safely navigate and maintain situational awareness, the radar altimeter is not considered a necessary instrument within this context.
