Safe Landings - June 2014
Message from the Editor: Though these incidents are all airline related, the systems involved are now also used in GA and could cause accidents.
Autoflight control modes generally involve interrelated functions of the Flight Management System (FMS), the flight director, the autopilot and autothrottles. The mode logic controlling the combined input of these systems can be very complex. Despite focus on design improvements and training emphasis on flight management modes, ASRS continues to receive a significant number of incident reports on mode related errors. While they usually result in minor “altitude busts” or crossing restrictions not met, mode errors can also lead to more serious outcomes including Controlled Flight Toward Terrain (CFTT).

Automation Issues
As autoflight system managers, Flight Crews are responsible for entering correct information into the flight management system, selecting the appropriate flight mode and monitoring the aircraft’s compliance with the desired flight path. As pilots, Flight Crews must maintain situational awareness, stay ahead of the aircraft, use good judgment, make sound decisions based upon training and experience, and do whatever is necessary (within the constraints of good airmanship) to put the airplane where it is supposed to be. These responsibilities apply not only to air carrier and corporate crews, but with the growing use of automation, to general aviation pilots as well.
This CALLBACK presents a few recent reports in which Air Carrier Flight Crews and a General Aviation Pilot share some lessons learned regarding automation issues

What Would You Have Done?
This “interactive” issue of CALLBACK, deals with two situations that involve General Aviation Pilots’ encounters with weather. In “The First Half of the Story” you will find report excerpts describing the situation up to the decision point. It is up to the reader to determine the possible courses of action and make a decision (preferably within the same time frame that was available to the reporter). The selected ASRS reports may not give all the information you want and you may not be experienced in the type of aircraft involved, but each incident should give you a chance to exercise your aviation decision-making skills. In “The Rest of the Story…” you will find the actions actually taken by reporters in response to each situation. Bear in mind that their decisions may not necessarily represent the best course of action. Our intent is to stimulate thought, discussion, and training related to the type of incidents that were reported.

See and Avoid
The number of midair collisions in the United States has averaged 30 per year since 1978.1 These accidents primarily involve General Aviation aircraft, but Air Carrier, Corporate and other operators are by no means immune from potentially serious airborne conflicts.
In the preceding 12-month period, more than 4,000 in-flight traffic conflicts were reported to NASA ASRS. Of these, 235 met the ASRS criteria (within 500 feet) for a Near Midair Collision (NMAC). Nearly half of these NMACs involved Air Carrier, Corporate and Air Taxi operations.
Technological advances such as the Traffic Collision Avoidance System (TCAS) and Conflict Alert (CA) have enhanced the ability of pilots and controllers respectively to resolve airborne conflicts before they become critical, but the following ASRS reports show that the “see and avoid” principle remains a crucial aspect of collision avoidance in visual conditions.

It has been said that the only voluntary act in aviation is the decision to take-off. Every action after take-off involves the skillful management of risk, the enjoyment of flight and a continuous stream of decisions that result in a safe landing.
In 1974, NASA created the Aviation Safety Reporting System (ASRS) to allow aviation professionals to share experiences in a frank, non-punitive manner. The ASRS structure allows pilots and other aviation professionals to file an anonymous report of an incident, error or occurrence that the contributor feels might be of value to others. These reports are gathered, analyzed and data based by NASA experts and made available to all interested parties as a tool for creating pro-active aviation safety programs. Additionally, NASA distributes an electronic publication, “CALLBACK,” which contains selected, de-identified, reports on a free subscription basis. In Flight USA is proud to reprint selected reports, exerted from “CALLBACK,” for our readers to read, study, occasional laugh at and always, learn from.

Motor Skills: Getting Off to a Good Start
A motor skill is a learned sequence of movements that combine to produce a smooth, efficient action. This month’s we look into another type of motor skill- the skill required to produce a smooth, efficient (and safe) aircraft engine start.

Preventable Fuel Management Errors: Fuel Exhaustion
Miscalculation: Determining fuel remaining based on assumed fuel burned figures and on gauges that are assumed to be correct is a dangerous gamble. This Piper Navajo pilot learned that physical verification of the fuel onboard is the best way to prevent miscalculations.

Paperless Flying
The day of the paperless cockpit has dawned, and with that, ASRS is hearing more about incidents involving Electronic Flight Bags (EFBs), as these electronic display systems are known.
EFB displays may be portable (Class 1), attached to a cockpit mounting device (Class 2), or built into the cockpit (Class 3). There is no doubt EFB devices are powerful and versatile. With display screens often the size of a laptop computer or approach plate, EFBs can display a variety of aviation data, including electronic manuals and documents, performance and planning data, moving maps and GPS, logs and checklists, spreadsheets, real-time weather, TCAS, terrain avoidance, email, and even the internet.
