On June 4, 2010, the Federal Aviation Administration issued Runway Safety Bulletin No. 32. The Safety Bulletin outlines significant changes to the procedure controllers use to issue a runway crossing clearance. The revisions take effect June 30, 2010. The two page document contains several procedural changes pilots should take note of:
- A controller must now issue “an explicit runway crossing clearance…for each runway crossing, even if the runway is closed or inactive.“ [Emphasis: Original document]
- Also, “Taxi instructions to cross multiple runways must not be issued. An aircraft/vehicle must have crossed the previous runway before another runway crossing may be issued.” [Emphasis: Original document]
- Finally, the practice of covering holding position signs during runway construction projects will end. Even when a runway is under construction, the holding position signs must be visible and well lit. As an aside, I honestly had no idea this was common practice… have I just missed this somehow?

Why all the changes? It’s an action designed to prevent runway incursions. What are runway incursions? The FAA defers to the definition of the international governing body of aviation — the International Civil Aviation Organization [ICAO -- pronounced "eye-kay-oh"]. ICAO defines a runway incursion as
“any occurrence at an aerodrome involving the incorrect presence of an aircraft, vehicle, or person on the protected area of a surface designated for the landing and take-off of aircraft.”
In plain English: any time an airplane or vehicle enters a runway without permission, it’s a runway incursion. Even if no other airplanes are present and no collision threat exists, a runway incursion occurs. As the numbers of runway incursions grew, the FAA began a safety initiative known as the Office of Runway Safety.
In the beginning, it was tough to see a common thread — lack of experience certainly wasn’t a factor. Too few student pilots and far too many ATPs were routinely violated for runway incursions. The FAA launched an aggressive education campaign. Through online courses, mailers, and free DVD materials, the FAA successfully brought the issue to the forefront in many company safety departments. Plans were put in place. Taxi checklists were shortened. The number of runway incursions began to decline. The numbers have fallen but in recent years have begun to level out. Compare the first three quarters of fiscal year 2010 to the same period in 2009 we see fifty less runway incursions in 2010 — a small drop when you consider the average quarter has close to two hundred incidents. Safety Bulletin 32 will hasten the decline in runway incursions. Our first real clue if the simple phraseology change reduces the number of actual runway incursions will come in the 4th quarter of 2010.

The FAA Safety Bulletin seeks to lower the number of runway incursions by canceling out the portion of the Aeronautical Information Manual that states whenever a controller clears an:
“aircraft to ‘taxi to’ an assigned takeoff runway, the absence of holding instructions authorizes the aircraft to ‘cross’ all runways which the taxi route intersects except the assigned takeoff runway.” [AIM 4-3-18]
Once the new rule is in effect, clearances no longer will contain an implied runway crossing clearance. Whether to cross or hold short will be explicitly stated. Clearance Example One, below, shows the old phraseology with an implied clearance.
1) Katana 322DC, Runway 19 — taxi via Juliet and Delta.
Now, we’ll need explicit direction to either hold short or cross the runway. We can expect one of two clearances:
2) Katana 322DC, Runway 19 — taxi via Juliet — cross Runway 14.
OR
3) Katana 322DC, Runway 19 — taxi via Juliet — hold short Runway 14.
Before June 30, Clearances One and Two were interpreted identically by pilots. Now, we must wait for instructions in order to cross any runway along our route.
An added perk of the new ATC procedure is the elimination of excessively long taxi clearances. With controllers restricted from issuing complex clearances to cross multiple runways, the taxi clearance naturally become shorter because the controller chunks the information into several smaller clearances. By chunking the information, the pilot is able to more easily remember the taxi clearance. Although, you really should not attempt to remember the taxi clearance — write it down.
What does it all mean for the MQY-based pilot?
- Starting June 30, you must be explicitly cleared to cross each runway. For pilots based at MQY, a thorough review of the airport diagram will benefit you greatly. Even though MQY has only two runways, it has EIGHT different intersections where a runway incursion could occur.
- When operating at an airport with multiple runways such as Nashville International [BNA], you will only be cleared to cross one runway at a time. Also understand the risk of an incursion is much greater simply because of the complexity of the taxiway systems at larger metropolitan airports. Smyrna seems complex and daunting with eight intersections but it pales in comparison to Nashville International which has over thirty different intersections.
- Before a flight, thoroughly review the airport diagrams for both departure and destination. These are easily found in the Airport/Facility Directory and can be downloaded or printed. The first time to reach for the airport diagram should not be when you exit the runway after landing. During cruise, take a look at the diagram and formulate a game plan. Find the path of least resistance to your parking area and that’s likely what the controller will give you. Even if he/she doesn’t, you’ve now spent ample time studying the airport diagram to adapt to change quickly.
- The holding position signs have white letters on a red background. Just like a stop sign. Anytime you approach one of these stop signs, look both ways for traffic before crossing. Also, if you have another pilot on board ensure he/she agrees that the flight has been cleared to cross the runway. If any crewmember is the slightest bit unsure, it’s time to verify with ATC. A quick “Ground, Katana 322DC, short memory, are we cleared to cross Runway 14 at Juliet?” usually does the trick nicely.
- When taxiing, use an airport diagram; Wings Of Eagles places a laminated MQY airport diagram in each aircraft. If you’re thinking don’t need the airport diagram for your home airport — think again. Let’s not forget, pilots don’t purposefully get involved in runway incursions — it happens through complacency, confusion, or both. On the part of either the crew or the controller. Where are you more likely to inadvertently enter a runway? At the metropolitan airport you are unfamiliar with, and thus therefore on edge and high alert. Or at your home airport where the comfort and calm of the familiarity after a long flight can quickly fade into complacency.
Since we’re on the topic of runway incursions — a few final words on safe taxi practices. Due to the high number of fatal automobile accidents related to text messaging, many states have adopted laws banning “texting while driving.” In January 2010, the U.S. Department of Transportation banned the use of mobile devices while operating a commercial truck or bus nationwide. Any commercial driver who violates this rule faces a fine of up to $2,750 from the DOT. While “texting while taxiing” is not usually a problem, I’ve seen many pilots complete checklists, organize the flight plan, program the GPS, and even begin the run-up during the taxi. These are often genuine attempts to expedite things in a hot and expensive aircraft. However, taxiing is simply not the time to be fiddling with a checklist, organizing the flight plan, or twisting buttons on the GPS. Taxiing an aircraft is a time to keep your head up and your eyes outside the cockpit.
Speaking of looking out the window, can you even see outside the cockpit? Or do you have to squint through a half inch of dead bugs? A good scrub off of the befallen bug brethren before each flight can greatly enhance your situational awareness by allowing you see where you are going. Try it sometime — you’ll be amazed at the increase in visibility. The cans and wipes are in the aircraft flight bag for that very purpose. Personally, I learned my lesson when I grabbed the controls from a student pilot and took evasive action to dodge what I thought was a Cessna coming at us head on — turns out it was a dead dragonfly only a foot away splattered on the canopy. I’ve been better about cleaning the windows since then… It’s funny how we pilot’s learn sometimes…

In conclusion — remember this wise radio communication advice above all else: if you are unsure of a clearance, ask for clarification. If you are unsure of the phraseology — just use plain English. Some of the biggest radio foul-ups happen when a pilot tries to convert to aviation talk. Talk to the human being in the tower, in plain English, and be one hundred percent certain you understand a clearance before accepting it. Ninety-nine percent of controllers will be happy you asked for clarification and even thank you for it. The other one percent may get testy, but even they would rather repeat the transmission than spend the afternoon doing paperwork for a runway incursion they should have prevented.
