Secretary of Transportation
400 Seventh Street, S.W.
Washington, D.C. 20590
Dear Mr. Secretary:
Congratulations on your appointment as Secretary of Transportation! You
bring a wealth
of knowledge and experience to this critical position from your years of
service in the Congress and as Chairman of the National Civil Aviation
Review Commission (NCARC). The transportation industry and traveling
public will be well served under your guidance.
I am writing to share my concern about
airport surface safety and to urge the Department
to become more proactive in efforts to address the prevention of runway
incursions and accidents. As you know, during my tenure as Chairman of
the National Transportation Safety Board (NTSB) during the
administration of President Reagan I was actively engaged in
investigating these occurrences and issuing recommendations to the
Federal Aviation Administration (FAA). The last accident I investigated
was the 1991 surface collision in Los Angeles involving U.S. Air and the
last public hearing I chaired involved the surface collision of two
Northwest Airliners in Detroit.
Although I have returned to Arkansas to practice law, I continue to
closely monitor this
safety issue by reviewing Congressional testimony, "Aviation Week and
Space Technology" magazine, "Air Safety Week", and other technical and
media reports. 1 also maintain numerous contacts in the aviation
industry with whom I communicate regularly about safety and capacity
matters, and especially the runway incursion hazard. I teach advanced
accident investigation and safety decision making for the Southern
California Safety Institute. I also follow aviation safety issues as a
member of the Air Traffic Control Association and International Society
of Air Safety Investigation.
It is my sense (and many others in
Congress, Government, and the aviation industry) that
runway incursions are the most critical safety issue confronting the
National Airspace System today. Runway incursions, with their potential
for an actual collision, are a serious and growing safety problem:
- Since 1993 the number of runway
incursions has increased 130
percent from 186 to 429 in 2000; the rate increased 110 percent
from .30 (per 100,000 airport operations) to .63.
- In the most recent year runway
incursions increased 33 percent
(321 in 1999 to 429 in 2000); the rate increased 28 percent (from
.47 to .63).
- During the first three months of 2001
runway incursions increased
15 percent (84 to 97) when compared to the same period during
2000. If this trend continues runway incursions will approach 500
in CY 2001, two and a half times the incidents occurring in 1994.

Also, six fatal runway collision
accidents have occurred in the United States since 1990.
These accidents, at Atlanta and Detroit in 1990, at Los Angeles in 1991,
at St. Louis in 1994, at Quincy in 1996, and at Sarasota in 2000,
resulted in 63 passenger and crew fatalities. On October 31, 2000, at
the Chiang Kai Shek Airport in Taipei, China, a Boeing B-747-400
collided with barriers and construction equipment during an attempted
takeoff on a closed runway resulting in 83 fatalities.
Further, critical runway incursions
involving air carrier aircraft that narrowly miss
colliding with another aircraft continue to occur all too frequently.
There are 30-40 such critical occurrences annually which have a high
potential for an actual collision. Examples of critical runway
incursions that have occurred this year to date include:
- 1/22/01 - At Seattle - Tacoma a TWA
MD-80 flew directly over an American MD-80 on the same runway with an
estimated minimum vertical distance of 50 feet between the two
airplanes.
- 1/24/01 - At Los Angeles an America
West B-737 taxied onto the
same runway where a Norontair B-737 was on landing roll out with
an estimated minimum distance of 100 feet on the surface between
the two airplanes.
- 2/21/01 - At Boston an American Eagle
Saub-340 taxied onto a
runway in front of a United B-757 who was on takeoff roll with an
estimated minimum distance of 50-100 feet on the surface between
the two airplanes.
- 3/4/01 - At Ft. Lauderdale a Delta
B-767 flew directly over a US
Airways B-737 (in position and hold on the runway) and landed
on the same runway with an estimated minimum vertical distance
of 50-100 feet between the two airplanes.
The runway incursion hazard will only be
exacerbated by future increases in aircraft
fleets, airport operations, and passenger enplanements. Just last month
at the FAA's 26th Annual Commercial Aviation Forecast Conference you
were quoted as saying that:
"commercial aviation will continue its
tremendous growth rate over
the next decade, further underscoring our nation's reliance on this
vital form of transportation, and
of course, guaranteeing the safety of the traveling public is and
always will be our number-one responsibility, and
however, working to close the gap between demand and the
capacity of our transportation infrastructure is a central challenge
for us in the aviation community"
FAA's forecasts include the following:
- Domestic passengers on U.S. airlines
are forecast to increase from
604.1 million in 2000 to 927.4 million in 2012 (3.6 percent
increase per year).
- The fleet of large air carrier jets
is expected to grow from 4417
aircraft in 2000 to 6313 in 2012 (3 percent increase per year).
- Commuter airline enplanements are
forecast to increase from 79.6
million in 2000 to 154.1 million in 2012 (5.7 percent per year).
- The regional jet fleet is expected to
increase from 569 aircraft in
2000 to 2190 in 2012 (11.9 percent annual increase).
- The cargo fleet is forecast to
increase from 1073 aircraft in 2000
to 1760 aircraft in 2012 (4.2 percent increase per year).
During 2000 the FAA held nine Regional
Workshops across the U.S. and a Human
Factors and Runway Safety Symposium to solicit ideas and input from the
industry on the causes and prevention of runway incursions. This was
followed by a Runway Safety National Summit in Washington, D.C. Nearly
1000 recommendations aimed at runway incursion prevention were received
from these meetings. These recommendations were condensed into 60
potential initiatives by combining similar proposals and eliminating
duplication. Ten initiatives were identified as "Ten Near-Term
Initiatives" because of their high potential for reducing runway
incursions and because they could be completed by the end of calendar
year 2000. The results of this process were published as the National
Blueprint for Runway Safety in October 2000.
The FAA has been slow to implement the
initiatives in the Blueprint, as has been the case
with its previous "Action Plans." For example, most of the Ten Near-Term
Initiatives have not been completed. Many are months behind schedule,
and in some cases no action has been taken to date. The remaining fifty
initiatives lack specific schedules, milestones, and funding. In fact,
the DOT Inspector General has testified twice this year (2/14/01 and
3/8/01) concerning the FAA's failure to "follow-through to ensure
initiatives were completed, evaluated, and the best ones spread to other
airports where they could make a difference."
My concern here is that very little is actually being done to address
the runway incursion hazard. The FAA convenes meetings and issues action
plans and blueprints, but falls short in its follow-up and
implementation of corrective actions. Simply, very little actually gets
changed. The FAA testifies that safety is its "primary goal," but the
agency's actions don't match the rhetoric, often superseded in favor of
enhanced system capacity and airport acceptance rates. I believe that
the potential for another fatal runway collision accident is high - we
can not continue to experience incidents where air carrier aircraft are
missing an actual collision by 100-200 feet and believe otherwise. In
many of these critical incursions the fact the airplanes did not collide
was by chance alone. There is an urgent need for proactive intervention
before another collision occurs.
Mr. Secretary, I urge you to focus your personal attention and the full
resources of the
Department on this very serious safety issue. It is time to energize the
FAA into action and
demand executive accountability. I recommend a four-part focused agenda:
organizational
changes, traffic management at the busiest airports, cockpit tools, and
an automated collision avoidance system for surface operations. The
first two could be done relatively soon while the remaining two will
take longer.
First, I recommend that the FAA's Runway Safety Program Office
management be
reassigned to the Office of the Secretary or the Office of the Assistant
Secretary for Safety. This would facilitate direct oversight of the
program by the Department. This new organization should be directed to
complete the initiatives contained in the Blueprint in an expedited
manner. Funding, schedules, and milestones should be established and
adhered to. I know this seems to be a radical recommendation but the FAA
has proved itself either unable, or more likely unwilling, in the face
of industry pressure, to handle this issue.
Second, there is a need to manage traffic flow and complexity at the
busiest airports to
reduce the potential for runway incursions. I believe there is a
significant correlation between the incidence of runway incursions and
the busy airports that are currently experiencing traffic delays. For
example, seven of the leading airports with delayed flights are also on
the top ten list of airports with the highest number of runway
incursions (all ten of the leading capacity constrained airports are on
the list of top 20 airports with runway incursions). Current efforts
intended to increase airport capacity and acceptance rates at these
already overloaded airports will only further jeopardize aviation
safety. I recommend that a study be performed immediately to validate
this correlation. The data need to be normalized and analyzed to measure
frequency congestion and controller and pilot work load to determine if
these factors increase the risk of runway incursions and, if they do,
measures need to be implemented to reduce and spread out the traffic to
an appropriate level. A study to address this issue is included in the
FAA's Blueprint under the Data, Analysis, and Metrics Thrust. I note
that in recent testimony the acting Chairman of NTSB addressed this same
issue; that the push to reduce delays "has the potential" to erode
safety. Until these studies can be completed preemptory measures must be
taken to reduce congestion at critical airports before this summer's
peak loads.
The third recommendation involves the
use of technology in the cockpit to help pilots
maintain situational and navigational awareness. Today's pilots taxi 75
million dollar aircraft
around the airport surface using paper charts of the airport layout,
looking out the cockpit
windows for signs, markings, and lighting (often misleading or
inadequate) to guide them. The use of this "flintstone" technology is in
stark contrast to the automation, flight management systems, satellite
and inertial navigation, auto land/brake systems, and conflict alert and
resolution technology (TCAS I & II, GPWS) that have been developed and
implemented for flight crew use during terminal and enroute operations.
Yet, we all can rent a car from AVIS that has a "never lost system" to
provide precise navigation guidance. This includes a moving map
supported by Global Positioning System data that presents detailed
information about your current position and your planned route to the
point of destination. This technology has been demonstrated successfully
by the National Aeronautics and Space Administration (NASA) in its
simulators and B-757 aircraft. Pilot deviations from cleared taxi routes
and hold short restrictions were virtually eliminated during simulator
sessions with pilots taxiing around Chicago O'Hare airport, which is one
of the most difficult to maneuver around. This technology — electronic
moving maps and head-up displays — is needed now. It could conceivably
prevent 50-75 percent of the runway incursions currently being
experienced by air carrier transport aircraft. The FAA needs to issue
rule making to require implementation and use of this technology by a
date certain: the use of an electronic moving map in two years, and a
head-up display with automatic dependent surveillance - broadcast
(ADS-B) of other aircraft in four years.
The fourth recommendation involves the need to develop and implement an
automated
collision avoidance system for surface operations. It should be based on
GPS surveillance of all aircraft and ADS-B broadcasting the location,
heading, acceleration, and other data (aircraft ident) to every other
aircraft. NTSB has been recommending the need for such a system for
years. Its most recent recommendation, dated July 6, 2000 is as follows:
Require, at all airports with
scheduled passenger service, a ground movement
safety system that will prevent runway incursions; the system should
provide a
direct warning capability to flight crews. In addition, demonstrate,
through
computer simulations or other means that the system will, in fact,
prevent
incursions. (A-00-66)
There is a striking precedent to such a
collision avoidance system for surface operations.
It is the one - TCAS - developed for airborne operations. From 1965 to
1986 there were 17 midair collision accidents (14 which were fatal)
involving air carrier aircraft in U.S. domestic airspace. These
collisions resulted in a total of 408 passenger and crew fatalities. The
NTSB investigated these midair collisions and repeatedly made
recommendations to the FAA 10 develop and implement a collision
avoidance system. The FAA "fumbled" along for years attempting to
develop a system, always waiting for the best rather than implementing
the good, similar to the FAA's current record of trying to implement the
Airport Movement Area Safely System (AMASS). Finally, the Congress
became so frustrated with the FAA's lack of progress that it directed
the FAA (Administrator Helms) to implement TCAS II for transport
aircraft. The results are startling: there have been no midair
collisions involving air carrier aircraft in the U.S. since 1986 (Cirritos,
CA). There is an urgent need lo accelerate the development and
implementation of a collision avoidance system for surface operations.
In summary, I urge you to involve
yourself in this serious safety issue. Despite good-faith
efforts by the FAA, NTSB, and the aviation industry to develop and
implement improvements to prevent runway incursions and accidents, they
continue to occur. The number and rate of reportable runway incursions
have increased significantly during the past years. Critical incursions
involving air carrier aircraft continue to occur all too frequently.
Aircraft fleets, airport operations, and passenger enplanements are
forecast to increase dramatically during the next ten years. This record
provides clear evidence that the potential exists for future runway
incursions and accidents, and it underscores the importance and urgency
of the need for immediate action to implement effective and realistic
solutions directed at runway incursion and accident prevention. The need
is for proactive intervention. The seriousness of this problem and the
urgency of preventing additional surface accidents justify the highest
level of attention to these efforts on the part of the Department.
To put this issue even more starkly, we
are presently in a crisis. I consider our country's
most congested airports to be UNSAFE. They will remain unsafe until
remedial action is taken. The short-term action required will be
painful, but will have the added benefit of hastening the implementation
of longer-term measures. Our nation is fortunate to have your leadership
during this crisis.
Should you need additional information or wish to discuss this matter
more in detail,
please telephone me at (501)745-2480. I have no business or commercial
interest in this issue and write to you solely out of concern of the
present risk of an aviation disaster involving two or more airplanes.
Respectfully yours,

Jim Burnett
