Situational Awareness–or SA as human factors specialists like to call it–is a term referring to pilots’ ability to keep the big picture in flight operations. This includes awareness of the aircraft’s location and attitude, its proximity to physical hazards and obstructions, weather and environmental factors, engine and systems status, task priority within the cockpit, and many other factors. Loss of situational awareness is often associated with poor weather, aircraft emergencies and other extreme situations. But more insidiously, loss of situational awareness also occurs in good visual conditions during routine operations. An air carrier Captain describes a case in point: While being vectored on a downwind leg to Runway 01L, Tower asked if we had the field in sight, which we did. At that time we were cleared for a visual approach to Runway 01L and a left turn back to the field was initiated to result in a final of approximately 6 miles. When approximately 60° from the runway heading, Tower reported traffic (a B-757) joining a final for runway 01R. While looking for the traffic the First Officer, who was flying the aircraft, took his eyes off the field and shallowed his bank... When I realized he was not just squaring off his final but was going to overshoot the runway I told him he was going to overshoot and ordered a turn back to our runway. He seemed disoriented and was slow in responding, resulting in a significant overshoot approaching the approach corridor for Runway 01R. A TCAS II-Resolution Advisory resulted with a monitor vertical speed command which was complied with. Tower questioned if we had the traffic in sight which we answered in the affirmative. We corrected back to the 01L centerline and landed with no further incident. In talking to the First Officer after the landing, he indicated that he lost sight of the runway in the left turn. Also that he never actually saw the B-757. Although I indicated that I saw the traffic and pointed it out, the First Officer did not see it, but I assumed he did. I also assumed that he had the runway in sight, so I was unaware that he had lost situational awareness. The lesson to me is to never assume another crew member is seeing the same thing I am and to work to communicate what I am seeing even when weather is good and easy visual approaches are being conducted. We trust this incident taught the First Officer the importance of communicating clearly with other crew when he does not have other traffic and the runway in sight.3. When did the pilot lose sight of the runway?

LOSA and Threat and Error Management – What is it? The line operations safety audit (LOSA) —which involves the collection of data by trained observers during routine flights to determine how flight crew detect, manage and mismanage threats and errors—has been endorsed by the International Civil Aviation Organization (ICAO) as a tool for monitoring normal flight operations and developing countermeasures against human error. The concept and methodology of LOSA currently are based on threat-and-error management (TEM). ICAO calls TEM the fifth generation of CRM, which, in the context of LOSA, is based on the premise that human error is normal, inevitable and a valuable source of information. Threats increase the operational complexity of the flight and pose a safety risk to the flight at some level. Threats include adverse weather conditions, hazardous terrain, aircraft and aircraft system abnormalities and malfunctions, time pressures and unfamiliar airports. Threats also include errors that are committed by others—including ground-handling personnel, maintenance technicians, dispatchers, flight attendants and air traffic controllers—and that must be managed by the flight crew. Flight crew errors are defined as actions and inactions that lead to deviations from the intentions or expectations of the flight crew or the airline. Errors, in the operational context, tend to reduce the margin of safety and increase the probability of accidents and incidents. The TEM model characterizes flight crew errors as follows: Communications errors include miscommunication, misinterpretation or failure to communicate pertinent information among the flight crew or between the flight crew and external agents such as air traffic controllers or ground-handling personnel. Examples include failing to hear air traffic control instructions, failing to read back ATC instructions and crew miscommunication. Intentional noncompliance errors are willful deviations from regulations and/or operator procedures. Examples include violating the sterile-cockpit rule; omitting required callouts; using nonstandard pilot-controller communication phraseology; conducting checklists from memory; and failing to respond to traffic alert and collision-avoidance system (TCAS) warnings or terrain awareness warning system (TAWS) warnings. Procedural errors are deviations in the execution of regulations and/or operator procedures in which the intention is correct but the execution is flawed. This category includes errors in which flight crew members forget to do something. Examples include failing to conduct checklists, incorrectly setting instruments and failing to cross-check instrument settings. Proficiency-based errors involve lack of knowledge or psychomotor (‘stick-and-rudder’) skills. Examples include inadequate knowledge of aircraft systems and equipment that contribute to hand-flying errors, automation errors or other errors that can influence the direction, speed or configuration of the aircraft. Operational decision errors are decision making errors that are not standardized by regulations or operator procedures and that unnecessarily compromise safety. An operational decision error includes at least one of the following conditions: the flight crew ignores a more conservative option; the crew member who took the decision does not brief other crew members about the decision; or the crew does not use available time to evaluate options. Examples include navigating through known areas of adverse weather and accepting ATC instructions that result in an unstable approach. The TEM model holds that when an error occurs, the flight crew either traps (detects and manages) the error; exacerbates the error with action or inaction that results in additional error, or fails to respond, that is to say, ignores the error. The ‘Management Tools’ of Threat and Error Management include: good situational awareness; a usable model for Aviation Decision Making such as, ‘Perceive, Process, Perform and Evaluate’; sharing information and good ideas through crew interaction, company newsletters, websites and other media of flight crew information exchange. Always keep in mind that the descent, approach and landing phases of a flight contain the most opportunities for threats and errors with serious outcomes.5. Which of the following is not a ‘Management Tool’ for Threat and Error Management?

Simply put, situation awareness is a case of having the three ‘R’s: knowing the right information at the right time and reacting to it appropriately. If we have all the information we need and we apply the proper procedures, getting safely to and from where we need to go becomes easy. Good situation awareness means that pilots know where they are, the desired route to their destination and any obstacles, hazards or rules to be followed along the way. At aerodromes with control towers, what the controllers intend and what the pilots understand must match exactly. If not, good situation awareness cannot occur either for pilots or for ATC. So if good situation awareness is essential for safe operations, how do we gain and maintain it? Another way of saying this is how and why do pilots loose their situation awareness bearings and make critical mistakes as a result? Research has shown that the following factors often result in diminished situational awareness: incomplete or misunderstood communications; lack of planning; work load peaks; distractions; and loss of visual cues. Let’s examine each to see how they may affect situation awareness.By far the most important cause of poor situation awareness induced mistakes is communication problems. Communication difficulties most often result from one or both of the following: use of non-standard phraseology; lack of language proficiency. These communications shortcomings cause a discrepancy between what ATC intends and what the pilots understand or vice versa. Clear, accurate and timely communications are essential in establishing and updating the shared mental picture necessary for good situation awareness.5. What is the best title of this article?
