Flying Under The LAX Bravo: The Special Flight Rules Area, Explained For Student Pilots

Every student pilot at Van Nuys learns to fly inside one of the most complicated pieces of sky in the country. Los Angeles International sits under a Class B airspace that climbs to 10,000 feet in stacked tiers, Burbank and Van Nuys have their own towers a few miles apart, and the mountains push everything into a valley. The first time you look at the Los Angeles terminal chart it looks like somebody dropped a plate of spaghetti on it.

It is less bad than it looks, and the piece that worries students most — getting from the Valley to the beach cities without a clearance through the Bravo — has a published answer that has been in use for decades. Here is how it works, and what we actually teach.

The Shape Of The Problem

Class B airspace exists to keep the airliners into LAX separated from everyone else, and you may not enter it without a specific clearance from air traffic control. The LAX Bravo is an upside-down wedding cake: the surface area sits over the airport itself, and the tiers step outwards and upwards until the outer ring tops out at 10,000 feet. Van Nuys is under one of those shelves, which is why your pattern work and your practice area to the north never touch it.

The trouble starts when you want to go south. Torrance, Long Beach, Orange County, Catalina — all of the good destinations on that side — are on the far side of LAX, and the Bravo stretches west over the ocean. You have three legal options: go around the outside, which from Van Nuys means a long detour; call SoCal Approach and ask for a clearance through, which they will give you when they can and refuse when they are busy; or use the Special Flight Rules Area.

What The Special Flight Rules Area Is

The Los Angeles Special Flight Rules Area is a corridor through the middle of the Bravo, directly over LAX, that VFR aircraft may fly without a clearance and without talking to air traffic control. It exists under its own section of the regulations, 14 CFR Part 93, and it has been there in one form or another for decades. Locals call it the corridor or the SFRA. Pilots from out of town, who have never heard of it, find it faintly unbelievable that you can fly over one of the busiest airports in the country without saying a word to anyone.

You can, provided you do exactly what the rule says. The corridor runs along the 132-degree radial of the Santa Monica VOR, straight across the top of LAX, and the rules are these:

Altitude. Southeast-bound, 3,500 feet. Northwest-bound, 4,500 feet. Not roughly — exactly. The two altitudes are what keep the traffic in each direction apart, and there is no radar service in there to save you if you drift.

Transponder. Squawk 1201. That code tells everyone watching a scope that you are a VFR aircraft in the corridor, which is why nobody calls you. You also need Mode C and ADS-B Out, as you do everywhere inside the 30-mile veil around LAX.

Radio. Monitor and self-announce on 128.55. There is no controller on that frequency; it is the corridor’s own common traffic advisory frequency, and the position reports on it are the only traffic picture you will get.

Speed. No faster than 140 knots indicated. Our aircraft cannot do that anyway.

Lights. Landing light on, and anti-collision lights, the whole way through.

The corridor takes about four minutes to cross in a trainer. On a clear day you look down at the terminals, the four parallel runways and the long lines of airliners on final, and it is one of the better views in general aviation.

How We Actually Fly It From Van Nuys

Leaving the Valley southbound you climb out and route to the Santa Monica VOR area, staying under the Bravo shelf on the way, then set up on the radial heading southeast at 3,500 feet with the transponder already on 1201 and the radio already on 128.55. Make your first call before you enter — aircraft type, position, altitude, southeast-bound — and a second one abeam the airport. Keep the wings level and the altitude nailed. Coming back, the same thing at 4,500 feet on the reciprocal.

What we drill into students is the part that happens before and after. The corridor itself is simple. The busy bit is getting to the Santa Monica VOR from Van Nuys without clipping the Bravo, and then, after you pop out the southeast end near Hawthorne and Torrance, getting your transponder back to 1200, getting on the right frequency for wherever you are going, and remembering that you are now in some of the densest general aviation traffic in the country. The corridor is not the hazard. Complacency on either side of it is.

The Other Ways Through

The SFRA is not the only published route across LAX, but it is the only one that needs no clearance. The Mini Route crosses lower, at 2,500 feet, and requires you to call LAX Tower and be cleared through with an assigned squawk. It is faster and lower and it is genuinely under the control of the tower, which is a different kind of flying from the self-announced corridor. There are also transitions along the coast that put you in touch with SoCal Approach. We teach the SFRA first because it teaches you to read the chart and fly the numbers with nobody holding your hand, and that is the skill the rest of Los Angeles airspace demands.

One thing we say to every student: the chart is the authority, not this article and not your instructor’s memory. Routes, altitudes and frequencies get revised. Before you fly any of these, look at the current Los Angeles terminal area chart and the FAA’s own SFRA depiction, and brief from those.

Why This Is Good For You

Students who train at quiet rural airports arrive at their first big-city airspace terrified of it. Students who train at Van Nuys spend their first forty hours flying under a Class B shelf, between two Class D towers, with a corridor over the busiest airport on the West Coast ten minutes to the south. By the time you take your checkride, an examiner asking you to explain the Bravo tiers and plan a route through them is asking about your commute.

That is worth a great deal later. An airline first officer’s job is precise altitudes, disciplined radio work and situational awareness in dense traffic, and a private pilot who learned here has been doing all three since lesson ten.

Come And See It

If you have never seen Los Angeles from 3,500 feet, the corridor is one of the best reasons to book a discovery flight: 60 minutes, you fly the aircraft yourself, the time is loggable dual instruction, and the $229 is credited in full against any program if you enroll within 24 hours. Tell us when you book that you want to see the airport and, weather permitting, that is where we will take you.
