FAA Ground School Practice Test

What is the minimum weather condition required for airplanes operating under special VFR in Class D airspace?

1. 3 miles flight visibility

2. 2 miles flight visibility

3. 1 mile flight visibility

4. No specific visibility requirement

The correct answer is: 1 mile flight visibility

For airplanes operating under Special Visual Flight Rules (SVFR) in Class D airspace, the minimum weather condition requires at least 1 mile of flight visibility. This rule is established to ensure that pilots can visually navigate and maintain a safe distance from other aircraft and ground obstacles while still being able to comply with the VFR requirements in less-than-standard weather conditions. The requirement for 1 mile of visibility allows pilots to operate safely when the weather is not ideal, but it is essential that they remain vigilant in visual navigation. In a Class D airspace environment, which is typically associated with lower traffic densities but still requires communication with air traffic control, having a minimum of 1 mile visibility is crucial to enhance safety and operational efficiency while allowing pilots the flexibility to operate under varying weather conditions. In contrast, higher visibility requirements such as 2 or 3 miles do not apply to SVFR operations in Class D airspace; instead, these are reserved for regular VFR conditions, which demand better visibility for general flight operations. Additionally, a lack of specific visibility requirement is not applicable in this context as the regulation does stipulate a clear minimum to ensure safety and coordination.
