When conducting an IFR departure, under what condition can the VCOA be authorized?

The Vertical Course Obstacle Assessment (VCOA) is a technique that allows pilots to safely navigate obstacle clearance while departing under Instrument Flight Rules (IFR) conditions. The authorization of a VCOA is specifically contingent upon the weather conditions.

When the weather is at or above 2300-3, it indicates that the visibility is at least 3 statute miles, and the ceiling is at least 2300 feet above ground level. This level of weather visibility ensures that pilots have adequate conditions to maneuver safely and visually after takeoff, allowing them to maintain situational awareness concerning obstacles. Essentially, having weather conditions that meet or exceed this threshold provides the required safety margin for a VCOA.

Other factors mentioned in the options, such as whether the airport is closed or designated for military use only, do not directly pertain to the authorization of a VCOA. While an airport must be operational for normal departures, the deciding factor for authorizing a VCOA remains the weather criteria as outlined.
