Contact Approach Aviation: What Part 91 and Part 135 Pilots Must Get Right

If ATC tells you to “proceed visually,” do you have a contact approach clearance? A visual approach clearance? The answer is neither — and getting that wrong in marginal weather has real consequences. Understanding contact approach aviation is essential for every instrument-rated pilot operating under IFR.

Contact approach aviation remains one of the most misunderstood corners of IFR operations for both general aviation and commercial pilots. A contact approach is a distinct IFR clearance with specific legal requirements, and confusing it with a visual approach or with informal ATC phraseology creates genuine operational risk. The consequences range from regulatory violations to compromised obstacle clearance when weather is marginal and decisions matter most.

This article is a definitive reference for instrument-rated Part 91 and Part 135 pilots. By the end, you will know the exact contact approach requirements IFR operations demand, the critical differences from a visual approach, the correct ATC phraseology, and how Part 135 standard operating procedures add restrictions that the FAA baseline alone does not capture.

What Is a Contact Approach in Aviation — and Why Does It Matter?

The FAA Aeronautical Information Manual defines a contact approach as an approach wherein an aircraft on an IFR flight plan, having received ATC authorization, operates clear of clouds with at least 1 statute mile flight visibility and proceeds to the destination airport by reference to landmarks. The governing regulatory framework falls under 14 CFR § 91.175 and the FAA AIM.

The contact approach minimums are specific and non-negotiable. The pilot must have at least 1 statute mile of flight visibility — not ground-reported visibility. The pilot must remain clear of clouds throughout the approach. The airport must have a published standard or special instrument approach procedure. And the pilot must be able to proceed to the airport using visual reference to the surface and landmarks.

Here is the requirement that catches pilots off guard: the pilot — not ATC — must initiate the request. ATC cannot assign a contact approach. This is a pilot-initiated IFR clearance, and it carries with it the pilot’s acceptance of obstacle clearance responsibility.

Despite being available to instrument-rated pilots for decades, the contact approach remains one of the most frequently confused approach types in training and in the cockpit. It is not a VFR shortcut. It is not a visual approach by another name. It is a risk-managed IFR tool with clearance requirements that demand clear understanding before use.

Contact Approach vs Visual Approach: Key Differences Pilots Confuse

A contact approach and a visual approach are not interchangeable. Confusing them — or assuming they carry the same requirements — creates genuine operational risk, particularly when weather is marginal. Understanding this distinction is foundational to safe IFR operations.

Who initiates. A contact approach is pilot-requested only. ATC cannot offer it, suggest it, or assign it. A visual approach, by contrast, can be initiated by ATC or requested by the pilot. This is the first and most fundamental difference in ATC approach authorization.

Visibility and weather requirements. The contact approach requires 1 statute mile flight visibility with the pilot remaining clear of clouds. A visual approach requires the pilot to have the airport or the preceding traffic in sight before ATC issues the clearance. The contact approach minimums are notably lower than standard VMC thresholds in controlled airspace — which is precisely why obstacle clearance shifts to the pilot.

Airport in sight. A contact approach does not require the airport to be in sight. The pilot proceeds by reference to landmarks. A visual approach requires the pilot to have the airport, runway environment, or preceding traffic in sight before ATC issues the clearance.

IFR status. Both approach types remain IFR operations. Neither transitions the flight to VFR. On a contact approach, obstacle clearance responsibility transfers entirely to the pilot. On a visual approach, ATC may still provide separation services depending on the environment.

Missed approach. On a contact approach, if the pilot cannot continue visually, the pilot must execute appropriate IFR procedures — which may mean requesting further ATC clearance or initiating a climb to a safe altitude. On a visual approach, standard go-around procedures apply and ATC separation is typically maintained.

Contact Approach vs Visual Approach: Side-by-Side Comparison

How to Request a Contact Approach: ATC Phraseology and Procedure

Knowing how to request a contact approach correctly begins with a deliberate radio call: “Request contact approach.” ATC will evaluate the reported weather and, if the airport has at least 1 statute mile flight visibility reported, may authorize the approach. The pilot then proceeds to the airport by visual reference to landmarks, remaining clear of clouds, while maintaining IFR status.

The January 22, 2026 FAA AIM Change 2 makes a clarification that is operationally critical. The FAA reinforced that certain common ATC phrases do not constitute a contact or visual approach authorization:

• “Request contact approach” — Correct pilot-initiated phraseology for a contact approach. ATC evaluates and authorizes.
• “Request visual approach” — Correct phraseology for a visual approach. Different clearance, different requirements, different initiation rules.
• “Proceed visually” — This is not authorization for a contact or visual approach. It is an ATC instruction with a different meaning and does not grant approach clearance.
• “Follow traffic” — This is not authorization for a contact or visual approach. It is a traffic-sequencing instruction, not an IFR approach clearance.

A pilot who hears “proceed visually” and assumes they have a contact approach clearance is operating outside their actual authorization — a situation that carries both safety and regulatory consequences.

Contact Approach Requirements Under Part 91 and Part 135

The FAA baseline contact approach requirements IFR operations mandate — 1 statute mile flight visibility, clear of clouds, published instrument approach procedure at the airport — apply equally under Part 91 and Part 135. The operational reality, however, diverges significantly.

Under Part 91, the pilot-in-command has broad authority. If the FAA minimums are met and the PIC determines conditions are safe, a contact approach is a legal and available tool. The FAA floor is the operative standard, and the decision rests with the pilot’s judgment.

Under Part 135, the picture is more complex. Certificate holders routinely impose internal limits that exceed the FAA baseline. Part 135 operations specifications and company SOPs may require higher visibility minimums, mandate stabilized approach criteria at specific altitudes or distances, require explicit crew coordination callouts before accepting a non-standard approach, or in some cases prohibit contact approaches entirely except under narrowly defined conditions.

A Part 135 pilot who knows the FAA minimum but disregards company restrictions may be in full FAA compliance while simultaneously violating their operator’s SOPs. That is not a hypothetical — it is a recurring finding in operational audits. For Part 135 operators building or updating recurrent training programs, CTS’s Part 135 Training covers approach authorization, crew qualification, and SOP compliance in depth.

Part 91 Flexibility vs Part 135 SOPs

A Part 91 pilot can legally request a contact approach whenever the FAA minimums are met and the PIC determines it is safe. A Part 135 pilot must also satisfy company operations specifications, training requirements, and SOP gates — including stabilized approach and go-around criteria that may be more conservative than anything the FAA requires.

This is a risk-management issue, not a regulatory checkbox. Training programs must test pilots on both the FAA rules and the company-specific restrictions that apply in their operation. A pilot who can recite 14 CFR § 91.175 but cannot articulate their company’s contact approach restrictions has a gap that matters in the real world.

Six Common Misconceptions About Contact Approaches

Even among experienced instrument pilots, contact approach aviation is rife with misunderstandings. These six misconceptions appear repeatedly in training evaluations, safety reports, and cockpit decision-making errors.

1. Misconception: A contact approach is a type of visual approach.
   Reality: It is a distinct IFR clearance. A contact approach does not require the airport to be in sight, and its minimums — 1 SM flight visibility, clear of clouds — differ fundamentally from visual approach criteria.
2. Misconception: ATC can assign a contact approach.
   Reality: The pilot must request it. ATC cannot initiate, suggest, or assign a contact approach.
3. Misconception: “Proceed visually” equals a contact or visual approach clearance.
   Reality: As clarified by FAA AIM Change 2 (January 22, 2026), “proceed visually” and “follow traffic” do not constitute authorization for either approach type.
4. Misconception: Contact approaches can be used at any airport.
   Reality: The airport must have a published standard or special instrument approach procedure, and the reported flight visibility must be at least 1 statute mile.
5. Misconception: Once on a contact approach, IFR responsibilities end.
   Reality: The flight remains IFR. Obstacle clearance is the pilot’s responsibility throughout, and the pilot must be prepared to execute a missed approach or request further IFR clearance if conditions deteriorate.
6. Misconception: Part 91 and Part 135 rules are identical for contact approaches.
   Reality: While the FAA baseline is the same, Part 135 operators frequently impose stricter SOPs — higher visibility minimums, stabilized approach gates, crew coordination requirements, or outright prohibitions under most conditions.

When to Use a Contact Approach: A Decision Tree for IFR Pilots

Knowing when to use a contact approach — and when to choose a different option — requires a structured decision framework. Work through these steps sequentially before committing to any approach type in marginal conditions.

Step 1: Is the airport in sight? If yes, a visual approach may be the most appropriate option. Confirm ATC clearance and proceed under visual approach criteria.

Step 2: If the airport is not in sight — is flight visibility at least 1 statute mile? Can you remain clear of clouds? Can you proceed by reference to landmarks? If yes to all three, a contact approach is a legal option. Request it from ATC and accept the clearance only if you are confident you can maintain obstacle clearance visually for the remainder of the approach.

Step 3: If conditions are uncertain or deteriorating — can you safely continue? If there is any doubt about maintaining the clear-of-clouds requirement or adequate flight visibility, continue with the published instrument approach or execute a go-around. The published approach is always the most conservative and protected option.

This decision tree is directly applicable to scenario-based recurrent training. It forces pilots to work through criteria sequentially rather than making intuitive leaps — exactly the structured decision-making that reduces errors when weather is marginal.

Training Takeaways: Applying Contact Approach Aviation Knowledge Under Pressure

The gap between knowing the definition of a contact approach in aviation and correctly applying that knowledge under pressure is where training makes the difference. Here are the actionable takeaways for pilots and training departments:

• Teach the decision tree. Every IFR approach scenario should force the pilot to evaluate four options in sequence: published instrument approach, visual approach, contact approach, or go-around.
• Include ATC phraseology exercises. Scenario-based training must test whether pilots can distinguish “request contact approach” from “proceed visually” and “follow traffic.” The 2026 AIM update makes this distinction directly testable.
• Part 135 training must address company SOPs — not only FAA minimums. Contact approach requirements are the floor. Part 135 curricula must reflect company-specific restrictions, stabilized approach criteria, and crew coordination callouts.
• Test obstacle clearance responsibility and missed approach planning. Exercises should place pilots in marginal VMC situations where they must manage the transition from instrument references to visual references — and back again if conditions deteriorate.
• Incorporate the 2026 AIM update into recurrent training immediately. The clarification on “proceed visually” and “follow traffic” is operationally critical and directly testable in recurrent evaluations.

Building these decision-making frameworks into your IFR recurrent training does not require starting from scratch. For Part 91 and Part 135 operators who need regulation-current, scenario-driven courseware that covers contact approach aviation and the full spectrum of IFR approach authorization, CTS’s Part 135 Training and IS-BAO/Part 91 Training programs are purpose-built to close exactly these gaps.
