On March 31, the FAA announced an important update for ops at KSFO/San Francisco.

The big news is that once work is complete on Runway 01R/19L, side-by-side parallel visual approaches will be permanently banned due to concerns over separation.

In fair weather conditions, this will effectively almost halve arrival rates. If you’re used to carrying a little less fuel to the Golden City when the sun is out, now is the time consider more.

Here is the background to this significant change to NORCAL ops.

FAA warning.

A new statement issued by the FAA warns operators of airborne delays.  The first reason is straight forward – Runway 01R/19L is currently closed until October due to repaving work.

But this isn’t temporary.

When re-opened, the FAA will introduce a new safety measure which will prohibit side-by-side approaches to the parallel east-west runways in clear weather. Even if pilots acknowledge having each other in sight.

Instead, approaches will be staggered, with one aircraft offset from the aircraft on the parallel runway.

This will essentially reduce arrival rates in VMC conditions to those typically experienced in IMC – from approx. 54 to 36 per hour.  It’s an issue the FAA concedes will persist, at least until safer solutions are found.

But why the change?

A spokesman for the FAA confirmed that the change of rule came about from a regular quarterly quality-assurance review.

The core issue is that the runway spacing is too tight.

The parallel runways are only 750 ft apart. That’s too close for independent parallel approaches under current FAA/ICAO standards.

So that leaves three options – space the runways out more (not practical), run precision monitoring systems (such as PRM) or, in the case of SFO, employ a workaround – the ol’ visual pairing trick – dependent visual approaches.

In other words, pilots maintain visual separation from the aircraft ahead and adjacent.

In good weather, ATC have historically run these side-by side. This boosts capacity but pushes separation responsibility onto pilots rather than ATC systems.

With its announcement, the FAA is finally saying that the workaround doesn’t meet modern safety standards anymore.

More broadly, the FAA’s safety philosophy is shifting away from ‘see-and-avoid’ in high-density terminal airspace towards more reliance on automatic ATC-based separation.

It seems that a human-dependent workaround to help mitigate struggling infrastructure is no longer an acceptable answer.

What is the practical impact?

Essentially, this is the end of SFO’s visual ‘capacity boost.’

In good weather, expect things to slow down much more than you’re used to. This includes longer finals, lengthier vectors, speed control and a greater chance of holding.

These impacts won’t be evenly spread. Expect the biggest delays during peak arrival periods, late afternoons/evenings or adjacent to weather related disruptions as it will be harder for ATC to play catch up when the weather improves.

For planning purposes, the main takeaways are to carry more fuel in fair weather conditions, and not to underestimate potential for delays. This is especially relevant for BizAv ops that have historically relied on visual arrivals to ‘keep things tight.’

Where to from here?

In its statement, the FAA confirmed that it is actively seeking new ways to boost arrival flows safely – we’ll need to wait a little longer for those.

Honeywell shared an interesting stat with us from the NBAA IOC held in San Diego the other week.

Most operators know about Guided Visual Approaches in the US. But when Honeywell asked crew about the European equivalent, more than 80% said they had never heard of them.

They’re called VPT approaches – Visual Manoeuvring with Prescribed Track.

You’ll find them at several European airports where terrain, noise restrictions or complex airspace make a straight-in approach impractical. Instead of flying a normal visual circuit, you follow a published visual track with defined waypoints and altitudes.

They’re relatively straightforward once you understand them, but can catch crew out if they show up un-prepared.

Let’s take a closer look.

What a VPT actually is

Traditional visual manoeuvring (especially circling) relies heavily on what we can see. That becomes challenging near hills, in poor weather or when unfamiliar with the airport.

VPT procedures aim to make this more structured.

Typically (but not always), you fly an instrument approach first. At a defined point, ATC will then clear you for VPT and you continue visually along a published track to the runway. The track can include visual reporting points, RNAV fixes or both.

If visual reference is lost at any point, you must go-around.

Because the track is defined, many operators load the waypoints into the FMS for extra guidance during the visual segment.

How are these different to guided visual approaches in the US?

At first glance they look similar. But operationally, they’re quite different.

In the US, visual approaches are usually flown from radar vectors. For a standard FAA visual approach, there’s no published procedure and no protected track. ATC simply vectors you into position, and clears you for a visual approach.

To help reduce workload, avionics providers like Honeywell and Garmin offer proprietary ‘Guided Visual’ procedures that can be selected and flown using FMS guidance.

But they are still just visual aids. Guided visuals are not published procedures, not part of the AIP, and ATC will usually not refer to them. Terrain and obstacles remain entirely the crew’s responsibility. More on this in our recent article.

But in Europe, VPT procedures are published in the AIP alongside instrument approaches.

More importantly, they are designed under ICAO PANS-OPS criteria. That means the procedure includes obstacle protection – but only if you follow the prescribed track accurately.

This leads into one of the most important differences:

VPT is not circling

Many pilots assume VPT works like circling, but it doesn’t.

Obstacle protection only exists along the defined visual track (as opposed to a circling area). If you drift away from that track, terrain clearance may no longer be guaranteed.

Therefore accuracy becomes more important than normal circling. Hence why many operators prefer to fly the VPT using FMS guidance where possible.

Beware the missed approach!

One detail that often catches foreign crews out is the missed approach.

Even though final segment is visual and may leave you offset from the runway, the missed approach normally follows the instrument procedure you were cleared for earlier.

This can mean an immediate turn or climb away from your visual track. It’s worth briefing this carefully before starting a VPT manoeuvre.

VPT vs RNP Visual – what’s the difference?

They can look similar on the chart, but they’re not the same thing. A VPT is a visual manoeuvre – you fly an instrument approach first, then continue visually along a prescribed track. You must remain visual throughout, and if you lose it, you go around.

An RNP Visual (like at LPMA/Madeira) is actually an instrument approach. Despite the name, you can fly it in IMC using FMS guidance all the way down to minima, with full obstacle protection. The visual part only comes at the very end for landing.

So although both involve curved paths and can feel similar, VPT relies on visual reference, while RNP Visual relies on navigation performance.

Some guidance on how to brief a VPT approach

If you’re not familiar with VPT approaches, here are the main things you want to talk about:

✅ Where does the VPT actually start? Some kick-off at a specific fix on the instrument procedure, others after a visual reporting point. Either way, clearly define when you are going head’s up.

✅ Is the path coded? Some VPTs include RNAV fixes that can be loaded into the FMS. Others rely purely on visual reporting points. If you can, use your FMS for guidance.

✅ Are there any altitude constraints along the visual segment? These are often included for terrain or noise abatement.

✅ What do we do if we miss? You might be following the instrument missed approach procedure, or there may be a special one. Check the chart for notes!
