The Fly Visual Segment, the Approach Chart Fine Print Every IFR Pilot Needs to Know, and What Happens When Instrument Guidance Ends Before the Runway Begins

On some instrument approaches, the published instrument guidance ends before reaching the runway. That transition point - where the procedure hands control from needles to eyeballs - is called a fly visual segment. Knowing exactly what it requires, before entering the clouds, is essential IFR airmanship.

What a Fly Visual Segment Is - and Why It Exists

Most instrument approaches deliver continuous guidance from the initial approach fix to a decision altitude or minimum descent altitude, where the pilot either sees the runway and lands or executes a missed approach. A fly visual segment exists when that model breaks down - when terrain, obstacles, or airspace geometry make it impossible to design an approach that aligns cleanly with the runway.

In those cases, procedure designers build an approach that pierces the weather and descends to a safe altitude clear of obstacles, then explicitly hand the pilot off to visual flight for the remaining distance. The instrument portion does its job. The rest requires the pilot’s eyes.

Aspen, Colorado is the most studied example in the United States. The approaches there have generated more training material and more serious accidents than almost any other facility in the country, precisely because the visual segment demands situational awareness and aeronautical skill that catches underprepared pilots off guard. Aspen isn’t unique - dozens of airports share similar characteristics without carrying the same reputation, which means pilots sometimes arrive without the same level of caution.

How to Identify a Fly Visual Segment on an Approach Chart

The chart notation is unambiguous once you know what to look for. In the profile view - the side-angle diagram showing altitudes and distances - a standard approach displays a continuous descent line. An approach with a fly visual segment shows that line ending at a specific point, with a dashed line continuing from that point to the runway. Sometimes the dashed segment shows a straight track; sometimes it depicts a turn.

The textual notes on the plate make the requirement explicit. Expect language such as “fly visual to runway two four” or a description of a specific turn to align with the runway environment. The dashes are not decorative - they mark where instrument guidance ends and where visual flight becomes the only legal option.

The Five Things to Brief Before Flying a Fly Visual Segment

1. Know Exactly Where Instrument Guidance Ends

Identify the precise point on the plate where the dashed line begins. It may be a named fix, a specific altitude, or a distance from the airport. That point demands a binary decision: continue visually, or fly the missed approach. There is no third option, and it needs to be pre-briefed - not read for the first time while already inside the weather.

2. Understand the Visibility Requirements

Fly visual segments typically carry higher visibility minimums than a standard straight-in approach. Procedure designers calculate the visibility needed to safely execute the visual track, which often involves terrain and an unfamiliar approach angle. Those numbers are not suggestions.

Reported weather might technically place the field above minimums in a general sense while still rendering the approach non-legal at the transition point. Check both figures. If the visibility requirement for the visual segment isn’t met, the legal time to stop is before beginning the descent - not at the transition point.

3. Brief the Visual Segment Track in Detail

This is where many pilots fall short. The instrument portion gets a thorough brief, the decision altitude gets locked in, the missed approach gets studied - and then the visual segment is treated as something that will resolve itself. It will not.

The visual segment has a specific depicted track with turns and a defined path from the end of instrument guidance to the runway threshold. Answer these questions on the ground: Which direction is the turn? How far is the runway from the transition point? What will the runway environment look like from this approach angle? If there’s a turn, how steep? What altitude applies during the visual segment? Some answers are on the plate. Others require the airport diagram and a look at surrounding terrain.

4. Understand the Missed Approach Trigger and Timing

At the transition point, the runway environment must be positively identified - the runway itself, runway lights, approach lights, or other references that allow identification of the runway and orientation to it. Not a vague brightness through the murk. Not clouds breaking up in the general direction. The runway environment, specifically. Without it, execute the missed approach immediately.

The more dangerous scenario is subtler: reaching the transition point with visual contact, beginning the visual segment, and then losing it. Clouds lower, rain moves in, or the visual reference turns out to have been misidentified. The answer is the same: execute the missed approach now. Descending further hoping to re-acquire the runway is not a procedure. In terrain, in marginal conditions, that decision has proven fatal.

Note also that the published missed approach procedure is designed to initiate from the missed approach point. If visual contact is lost partway through the visual segment, the aircraft is no longer at that reference position. Knowing the surrounding terrain and airspace before starting the approach directly governs the safety margin if the missed approach must be flown from an unexpected location.

5. Manage Energy State Before the Transition Point

By the time the transition point arrives, a pilot has typically been heads-down cross-checking instruments and managing the approach. The visual segment may require a turn, a descent, or both - often immediately. Arriving fast, un-configured, with flaps in transition and a ninety-degree turn ahead is a dangerous way to begin a visual maneuver in marginal conditions.

The better mental model: treat the visual segment as the beginning of a visual approach, not the end of an instrument approach. The instrument portion was the tool that got to this point. The visual approach starts now. Apply the same stabilized-approach discipline from here to touchdown.

Fly Visual Segment vs. Circling Approach: The Key Differences

These two procedures share surface similarities - both involve transitioning from instrument guidance to visual maneuvering - but they are not interchangeable.

A circling approach delivers the aircraft to the minimum descent altitude, from which the pilot circles the airport visually to align with the landing runway. The procedure has published minimums and general guidance, but the pilot determines exactly how to execute the circle based on conditions and traffic. It begins at the absolute bottom of instrument guidance, with no further altitude to work with.

A fly visual segment is more constrained. The procedure includes a specific depicted track that must be followed - the pilot is not circling freely but flying a defined path built around terrain, obstacles, and airport geometry. Critically, the segment typically begins from an altitude above the minimum descent altitude, providing some maneuvering room. That depicted track is not optional. It is the procedure.

Where to Find the Official Guidance

FAA Advisory Circular 90-97 covers visual flight rules flight in instrument meteorological conditions and provides the regulatory foundation for these segments. The FAA Instrument Flying Handbook includes a section on non-standard approaches that addresses fly visual segments directly. Both are worth reading for primary source material beyond the chart.

BoldMethod’s written coverage of fly visual segments is particularly useful for instrument pilots building IFR proficiency. The connection between chart annotation and operational implications is explained clearly, and for pilots newer to IFR flying, having that notation decoded alongside practical context is a strong supplement to the official handbooks.

Key Takeaways

• A fly visual segment is a published point where instrument guidance intentionally ends and visual flight must begin, depicted as a dashed line in the approach chart’s profile view.
• At the transition point, the runway environment must be positively identified - not approximated. Without it, the missed approach is immediate and non-negotiable.
• Fly visual segments carry higher visibility minimums than standard approaches; confirm those numbers before descending.
• The visual segment has a specific depicted track that must be briefed and followed - it is not a flexible circling maneuver.
• If visual contact is lost during the visual segment, execute the missed approach immediately. Descending further is not an option.
• Aspen, Colorado is the most prominent U.S. example, but dozens of airports have fly visual segments without the same cautionary reputation.
