ASRS CALLBACK includes excerpts from ASRS incident reports with supporting commentary. In addition, CALLBACK may contain summaries of ASRS research studies and related aviation safety information. CALLBACK is one of the ASRS's most effective tools for improving the quality of human performance in the National Aviation System (NAS) at the grass roots level.

What Would You Have Done?

This month we offer another "interactive" issue of CALLBACK, inviting you to exercise your decision-making skills in response to dilemmas described by ASRS reporters. The front page presents four incident report excerpts followed by several plausible decision choices. Which of these choices seem the safest to you? On the back page, you will find the rest of the story – the actions taken by reporters to resolve their situations. You may find that reporters' actions do not always reflect what you would have done, or represent optimal safety solutions. We hope you will find this material thought-provoking.

'Slip Slidin' Incidents from ASRS

In our many years of reading ASRS reports, we've found that mentions of "slides" and "slips" frequently culminate in unfortunate outcomes. As you would expect, some of these incidents are weather-related, but many others are not. In our November issue, we offer a broad sampling of recent 'slip-slidin' incidents, including air carrier runway and taxiway excursions, cabin crew miscues, slippery maintenance procedures, and GA takeoff and landing mishaps.

Slip slidin' away
Slip slidin' away
You know the nearer your destination
The more you're slip slidin' away.

(Paul Simon)

The ASRS Weather Hit Parade

It will come as no surprise to users of the ASRS Data Base Online that many ASRS incident reports contain descriptive references to weather—rain, freezing rain, thunderstorms, frost, snow, ice, hurricanes, tornados, lightning, dust storms, wind, microbursts, and hail—not to mention unlimited ceilings and visibility. But did you realize that hundreds of pop song titles also use weather words to good effect?

For our October issue, we sample a variety of weather-related ASRS incident reports through pop song titles—from "Terminal Frost" to "Snowbird."

Aviation Training Incidents

Training is a constant activity in almost every aviation environment, from instruction of pilots to training of mechanics and air traffic controllers. This month we look at a selection of recent ASRS reports that involve common training dilemmas. These include:

- Letting the student go too far
- Instructor loss of focus
- Student over-reliance on the instructor.

Cockpit Technology Surpises

As more General Aviation aircraft are equipped with autopilots, GPS, and glass cockpit displays, ASRS is also hearing more about pilots' "learning curve" with technology that has long been standard in air carrier cockpits. GA pilots increasingly experience equipment-related altitude busts, track deviations, and other incidents. This month we present both GA and air carrier reports that demonstrate the need for pilots to:

- Understand how advanced systems execute commands before using these systems in flight.
- Monitor the airplane's flight path when ATC issues clearance changes that require re-programming.
- Resist the urge to extensively troubleshoot automation that is not working as expected.

What Would You Have Done?

ASRS continues to receive feedback from CALLBACK readers that our "interactive" issues (requiring readers to assess possible solutions to reporters' problems) are thought-provoking and educational. On this month's front page, you will find a selection of incident report excerpts (the "first half of the story"), followed by several plausible answer choices. Select the answer choice for each incident that seems the best course of action. On the back page, you will find the "rest of the story" – the actions actually taken by reporters to resolve their situations.

Keep in mind that reporters' actions may not always represent optimal safety solutions, and that these incidents are intended to foster further thought and discussion.

Communication Factors in ASRS Reporting

In the words of a contemporary author, "Communication works for those who work at it." This principle is evident in ASRS communications-related reports when pilots and controllers resolve to learn from their errors, and employ strategies to prevent future communications incidents.

This month we take a closer look at three factors in aviation that can contribute to communications misunderstandings and result in hazardous events. These are:

- The Anticipation Factor
- The Language Factor
- The Call Sign Factor

Heading Clues and Cues

When to flying pursuits you're inclined,
Keep procedures and training in mind,
And when soaring the blue,
Heed those instincts and clues
That tell you you're getting behind.
- Editor

In this month's CALLBACK, we'll sample a selection of ASRS incident reports that describe how some pilots and air crews missed – or heeded – important clues to flight safety. Our selection includes general aviation, air carrier, and maintenance incidents.

Problems with PDC Formats

In 1990, the Pre-Departure Clearance (PDC) program was introduced at a number of U.S. airports. This system allows pilots to obtain IFR clearances through aircraft ACARS (Aircraft Communication Addressing and Reporting System) display units prior to taxi. The program has dramatically reduced voice communications and related frequency congestion on Clearance Delivery frequencies at participating airports.

ASRS performed analyses of PDC related incidents in 1993 (Directline Issue #5) and 1996 (Operational Issues Bulletin), and found that confusing PDF formats were one of the leading problems reported. Both the Directline article and the Operational Issues Bulletin are available on the ASRS web site (http://asrs.arc.nasa.gov/publications/), under "Safety Publications."

Another increase this past year in PDC-related reporting prompted ASRS to revisit PDC issues. A recent review of 71 relevant incident reports confirmed that a concern we first identified 16 years ago—PDC formats—is still a problem for many pilots. Specifically, our recent review identified the following PDC format issues:

• Listing of both filed and cleared routes

• Unclear routing formats

• Unnecessary route revisions (amendments).

ASRS Communication Incidents

Effective communications are an integral part of safe operation in today's National Airspace System. This month's CALLBACK focuses on communications-related incidents reported by a controller and several pilots. These include:

• Misuse of Guard frequency (121.5 MHz)
• ATC emergency handling
• TFR avoidance
• Compliance with charted procedures, and
• Clearance clarity.

ASRS Fifth Annual Award-Winning Performances

For the past four years, CALLBACK has presented a selection of "best" reporter actions in incidents submitted to the ASRS. In this fifth annual issue of award-winning performances, we offer a selection of incidents that were handled with creativity, skill, and professionalism. We believe these incidents illustrate the value of communication, training, and teamwork when adverse events occur.
