Visual Climb Over Airport (VCOA): Understanding This Unique Instrument Departure Option

Departing an airport under IFR can be especially challenging in areas with mountainous terrain, obstacles, or limited departure paths. While many pilots are familiar with Obstacle Departure Procedures (ODPs) and Standard Instrument Departures (SIDs), fewer fully understand another important tool: the Visual Climb Over Airport (VCOA).


A VCOA is a specialized departure option that combines visual maneuvering with IFR clearance, allowing pilots to safely climb to a protected altitude before proceeding on an instrument route. This article explains what a VCOA is, why it exists, when it can be used, and what responsibilities it places on the pilot.

What Is a Visual Climb Over Airport (VCOA)?

A Visual Climb Over Airport (VCOA) is a published departure procedure that allows a pilot to:

  • Depart under IFR

  • Remain within the visual area of the airport

  • Climb visually in a circling or maneuvering pattern

  • Reach a specified altitude

  • Then proceed on the IFR route or enroute structure


The key requirement is that the pilot must maintain visual reference with the airport environment at all times during the climb.


Why VCOAs Exist

VCOAs are developed for airports where:

  • Terrain or obstacles surround the airport

  • Standard straight-out climbs are unsafe or impractical

  • Required climb gradients exceed aircraft performance

  • Instrument departure paths cannot guarantee obstacle clearance


Instead of forcing an aircraft into a narrow or steep departure corridor, a VCOA allows the pilot to climb above the airport, where obstacle clearance can be assured before transitioning to IFR navigation.


Where VCOAs Are Published

VCOAs are published in the:

  • Takeoff Minimums and (Obstacle) Departure Procedures section of the Terminal Procedures Publication (TPP)


They are textual procedures, not graphical charts, and are airport-specific.


Key Elements of a VCOA

A typical VCOA description includes:

  • A minimum visibility requirement

  • A minimum climb altitude

  • Instructions to remain within a specified distance of the airport

  • A requirement to maintain visual contact with the airport


Example (paraphrased):

  • “Climb in visual conditions over the airport to 7,500 feet before proceeding on course.”


Visibility Requirements

Unlike standard ODPs, VCOAs always include a visibility requirement.


This is because:

  • Obstacle clearance depends on the pilot’s ability to see and avoid terrain

  • The maneuvering is conducted visually, not by instruments


If the published visibility requirement cannot be met, the VCOA may not be used.


Pilot Responsibilities During a VCOA

When flying a VCOA, the pilot is responsible for:

  • Maintaining visual conditions at all times

  • Remaining clear of terrain and obstacles

  • Staying within the vicinity of the airport

  • Achieving the required altitude before proceeding IFR

  • Transitioning smoothly to instrument navigation once conditions permit


ATC does not provide obstacle separation during the visual portion of the climb.


VCOA vs. ODP vs. SID

Understanding how a VCOA differs from other departure procedures is critical.


VCOA vs. ODP

  • ODP: Instrument-based obstacle clearance

  • VCOA: Visual obstacle avoidance

  • ODPs may be flown in IMC; VCOAs may not


VCOA vs. SID

  • SID: ATC-assigned, traffic-flow oriented

  • VCOA: Pilot-initiated, obstacle-focused

  • SIDs require clearance; VCOAs do not unless specified


IFR Clearance and ATC Interaction

A VCOA does not require specific ATC clearance to fly, but:

  • Pilots should advise ATC if planning to use a VCOA

  • ATC may issue restrictions or alternative instructions

  • Radar coverage may be limited near mountainous airports


Clear communication reduces confusion and improves safety.


Performance Considerations

Before attempting a VCOA, pilots must carefully evaluate:

  • Aircraft climb performance

  • Density altitude

  • Weight and balance

  • Engine performance

  • Weather trends


A slow-climbing aircraft may remain in the obstacle-rich environment longer than anticipated, increasing risk.


Weather Considerations

VCOAs are especially sensitive to:

  • Marginal VFR conditions

  • Rapidly changing ceilings

  • Mountain obscuration

  • Smoke, haze, or precipitation


If visual conditions deteriorate during the climb, the pilot may have no safe escape option.


Training and Checkride Relevance

VCOAs are frequently discussed during:

  • Instrument rating oral exams

  • Mountain flying training

  • CFI checkrides


Common questions include:

  • “When can you fly a VCOA?”

  • “Is a VCOA mandatory?”

  • “Who is responsible for obstacle clearance?”

  • “What happens if you lose visual conditions?”


Best Practices for Using VCOAs

  • Treat VCOAs as last-resort options

  • Prefer standard ODPs when possible

  • Brief the maneuver thoroughly

  • Establish clear personal weather minimums

  • Avoid night or marginal conditions unless highly proficient


Conclusion

The Visual Climb Over Airport is a valuable—but demanding—tool in IFR departure planning. It shifts obstacle clearance responsibility from procedure design to pilot judgment, requiring strong situational awareness, solid aircraft performance, and favorable weather.


Pilots who understand when and how to use a VCOA gain flexibility at challenging airports—but only when used conservatively and correctly.
