Definition
A departure procedure option used at airports with obstacles in the surrounding terrain that cannot be cleared using a standard climb gradient. Instead of climbing straight out, the pilot remains visually over the airport and circles upward until reaching a published minimum altitude, then proceeds on course. A VCOA may only be used in visual meteorological conditions and requires the pilot to advise ATC before departure that a VCOA will be flown.
Plain English
A way to depart from an airport surrounded by terrain or obstacles by climbing in circles directly over the airport — where you can see the ground — until you are high enough to safely fly away.
Context Anchor
Seen in instrument departure procedures and takeoff minimums, especially where terrain or obstacles make a normal straight-out climb unsuitable.
Why Pilots Care
It provides a safe departure option when standard climb gradients cannot be met due to obstacles.
Grounding Statement
The key idea is: climb where you can see and stay near the airport until you are high enough to safely continue the instrument departure.
Intuition Check
Do not assume VCOA means you can depart any way you want just because you can see outside. It is a published instrument departure option with specific weather, altitude, and routing requirements.
Example Sentence 1
Because the surrounding ridges required a steep climb gradient, the pilot elected to fly the VCOA, circling over the field until reaching 9,000 feet before proceeding on course.
Example Sentence 2
VCOA procedures appear in the departure section of the instrument chart for this airfield.
