Which statement is correct concerning special VFR operations at Addison Airport?

The correct statement regarding special VFR operations at Addison Airport indicates that they are permitted at all times, regardless of the time of day. Special VFR allows pilots to operate in visual flight rule conditions even when the weather does not meet the normal VFR minimums for visibility and cloud clearance. This means that under certain conditions, pilots can navigate visually with lower visibility than required for standard VFR operations, allowing for greater flexibility in flight operations.

In many cases, special VFR operations require coordination with air traffic control to ensure safety, particularly in busy airspace, but the fact that they are permitted at all times means that they are not restricted to specific daylight hours and are accessible whenever the necessary conditions are met, including during night operations. The requirement for explicit clearance from ATC is important but does not negate the fact that these operations can occur whenever conditions allow.

Other statements such as those suggesting restrictions to daytime or to helicopter operations do not align with the broader access provisions for special VFR and thus are not accurate.
