“Cleared for the Approach”: What It Really Means — and Where Pilots Get Burned
Flight Brief #02
“Cleared for the approach” sounds straightforward. In practice, it’s one of the most commonly misunderstood clearances in IFR flying. The mistake isn’t usually a lack of skill — it’s a misunderstanding of what responsibility just shifted, and to whom.
At the center of this is 14 CFR §91.123, which states that once you accept an ATC clearance, you may not deviate from it unless it’s amended, an emergency exists, or you’re responding to a TCAS resolution advisory. That sounds obvious, but it’s where a lot of pilots go wrong — because they treat approach clearances, especially visual ones, as open-ended. They’re not.
Instrument Approaches: Structured and Protected
When ATC clears you for an instrument approach, the system is still highly structured. Per AIM 5-4-7, that clearance authorizes you to fly the published procedure — but only within its design. The key detail many pilots miss is that you cannot descend simply because you were cleared. You must be established on a published segment of the approach, a feeder route, or a proper vector to final before beginning descent.
This matters because obstacle protection is tied directly to those segments. Descending early — before you’re established — means you’ve stepped outside the protected airspace the procedure was designed to provide. That’s not just procedural sloppiness; it’s how controlled flight into terrain scenarios begin.
Once established, the rules tighten again. Step-down fixes and altitude constraints are mandatory unless ATC explicitly cancels them. Being cleared for the approach does not erase those requirements. It simply authorizes you to begin flying them.
Visual Approaches: Flexibility With a Cost
The moment you accept a visual approach, the structure changes. Under AIM 5-4-23, you must have either the airport or preceding traffic in sight and remain clear of clouds. More importantly, you assume responsibility for your own terrain and obstacle clearance.
That’s the trade. ATC gains flexibility in sequencing, and you gain flexibility in how you get to the runway — but you also lose the built-in protection of a published procedure.
Controllers, per FAA Order JO 7110.65, still handle sequencing and maintain IFR separation unless they explicitly transfer that responsibility. But they are no longer guaranteeing a safe descent path. That’s now on you.
This is where pilots get casual. A visual approach feels easier, so discipline drops. Descents get improvised, profiles get unstable, and positioning gets sloppy. The clearance didn’t lower the standard — you did.
Visual Separation: Know When It’s Yours
There’s another layer that often gets blurred: visual approach vs. visual separation.
If ATC simply clears you for a visual approach, they are still responsible for separation between IFR aircraft. However, if they add:
“Maintain visual separation”
Now the responsibility shifts. Under JO 7110.65, 7-2-1, you are responsible for keeping yourself clear of that traffic. That’s a meaningful transfer of responsibility, not a casual instruction. If you accept it, you own it.
The Long Base Question
A common real-world scenario: you’re cleared for a visual and want to stretch it out — long downwind, extended base, maybe a 10–15 mile final.
Is that allowed? Yes — but not unilaterally.
Under §91.123, you are required to comply with the clearance as issued. A visual approach does not grant permission to maneuver however you want; it assumes you will fly in a way that fits ATC’s sequencing plan. If you decide on your own to extend significantly without coordination, you may be deviating from that plan — even if no one has said a word yet.
The correct move is simple: ask. If you request an extended base or long final and ATC approves it, it becomes part of your clearance. Now you’re compliant. Without that coordination, you’re guessing — and guessing inside a managed traffic system is where problems start.
The Instrument-to-Visual “Switch”
Another situation that catches pilots off guard is the midstream transition: you’re cleared for an ILS. Then ATC asks if you have traffic in sight. You say yes. They respond:
“Cleared visual approach.”
That’s not a minor change — it’s a fundamental shift. ATC is likely solving a spacing problem and needs flexibility. In doing so, they’ve just removed the structured protection of the instrument approach and handed you more responsibility.
You can still use the ILS or RNAV glidepath as a reference, and many experienced pilots do. But understand this clearly: you are no longer protected by that procedure. If you drift off profile or descend early, that’s on you — not the chart, not ATC.
Where Pilots Get in Trouble
The common thread in most errors here is assumption. Pilots assume clearance equals freedom. They assume visual equals easier. They assume “not told otherwise” equals authorized.
That’s not how §91.123 works. Compliance isn’t just about following explicit words — it’s about staying within the intent and structure of the clearance you were given.
The Bottom Line
An instrument approach gives you structure and protection, but demands discipline. A visual approach gives you flexibility, but shifts responsibility. Visual separation can shift even more of that responsibility onto you.
The clearance didn’t get simpler — you just took on more of the workload.
One Line to Keep You Grounded
If you don’t clearly understand what’s protecting you — or who is — then you’re not ready to descend.
