- 0:00Equipment use autopilot systems. In a single pilot environment, an autopilot system can
- 0:08greatly reduce workload prefer to Figure seventeen Dash twenty. As a result, the
- 0:14pilot is free to focus his or her attention on other flight deck duties.
- 0:18This can improve situational awareness and reduce the possibility of a sea fit accident.
- 0:24While the addition of an autopilot may certainly be considered a risk control measure,
- 0:29the real challenge comes in determining the impact of an inoperative unit. If the
- 0:34autopilot is known to be inoperative prior to departure, this may factor into the
- 0:39evaluation of other risks. For example, the pilot may be planning for a
- 0:44VHF omnidirectional range ther approach down to minimums on a dark night into an unfamiliar
- 0:51airport. In such a case, the pilot may have been relying heavily on
- 0:55a functioning autopilot capable of flying a coupled approach. This would free the pilot
- 1:00to monitor aircraft performance. A malfunctioning autopilot could be the single factor that takes
- 1:06this from a medium to a serious risk. At this point, an alternative
- 1:11needs to be considered. On the other hand, if the autopilot were to
- 1:15fail at a critical, high workload portion of this same flight, the pilot
- 1:21must be prepared to take action instead of simply being an inconvenience. This could
- 1:26quickly turn into an emergency if not properly handled. The best way to ensure
- 1:30a pilot is prepared for such an event is to carefully study the issue prior
- 1:36to departure and determine well in advance how an autopilot failure is to be handled.
- 1:42Familiarity. As previously discussed, pilot familiarity with all equipment is critical in
- 1:49optimizing both safety and efficiency. If a pilot is unfamiliar with any aircraft systems,
- 1:56this will add to the workload and may contribute to a loss of situational
- 1:59where This level of proficiency is critical and should be looked upon as a requirement,
- 2:05not unlike carrying an adequate supply of fuel. As a result, pilot
- 2:09should not look upon unfamiliarity with the aircraft in its systems as a risk control
- 2:14measure, but instead as a hazard with a high risk potential. Discipline is
- 2:20key to success. Respect for onboard systems. Automation can assist the pilot in
- 2:27many ways, but a thorough understanding of the system or systems in use is
- 2:31essential to gaining the benefits it can offer. Understanding leads to respect, which
- 2:37is achieved through discipline and the mastery of the onboard systems. It is important
- 2:42to fly the airplane using minimal information from the primary flight display PFD. This
- 2:47includes turns, climbs, descents, and being able to fly approaches. Reinforcement
- 2:53of onboard suites. The use of an electronic flight display may not seem intuitive,
- 3:00but competency becomes better with understanding and practice. Computer based software and incremental
- 3:07training help the pilot become comfortable with the onboard suites. Then the pilot needs
- 3:12to practice what was learned in order to gain experience. Reinforcement not only yields
- 3:17dividends in the use of automation, it also reduces workloads significantly. Getting beyond
- 3:24ROTE workmanship. The key to working effectively with automation is getting beyond the sequential
- 3:30process of executing an action. If a pilot has to analyze what key to
- 3:36push next, or always uses the same sequence of keystrokes when others are available,
- 3:42he or she may be trapped in a ROTE process. This mechanical process
- 3:46indicates a shallow understanding of the system. Again, the desire is to become
- 3:52competent and know what to do without having to think about what keystroke is next.
- 3:58Operating the system with potency and comprehension benefits a pilot when situations become more
- 4:03diverse and tasks increase, understanding the platform. Contrary to popular belief, flight
- 4:12in aircraft equipped with different electronic management suites requires the same attention as aircraft equipped
- 4:17with analog instrumentation and a conventional suite of avionics. The pilot should review and
- 4:24understand the different ways in which the EFD are used in a particular aircraft.
- 4:30Refer to Figure seventeen twenty one two simple rules for use of an ef D.
- 4:36Be able to fly the aircraft to the standards in the pts. Although
- 4:42this may seem insignificant, knowing how to fly the aircraft to a standard makes
- 4:46a pilot's airmanship smoother and allows him or her more time to attend to the
- 4:50system instead of managing multiple tasks. Read and understand the installed electronic flight systems
- 4:58manuals to include the use of the autopilot and other onboard electronic management tools.
- 5:04Managing aircraft automation. Before any pilot can master aircraft automation, he or she
- 5:11must first know how to fly the aircraft. Maneuver's training remains an important component
- 5:16of flight training because almost forty percent of all general aviation accidents take place in
- 5:21the landing phase, one realm of flight that still does not involve programming a
- 5:27computer to execute. Another fifteen percent of all general aviation accidents occurs during takeoff
- 5:32an initial climb. An advanced avionic safety issue identified by the FAA concerns pilots
- 5:41who apparently develop an unwarranted overreliance in their avionics and the aircraft, believing that
- 5:46the equipment will compensate for pilot shortcomings. Related to the overreliance is the role
- 5:53of ADM, which is probably the most significant factor in the general aviation accident
- 5:59record. Of high formance aircraft used for cross country flight. The FAA Advanced
- 6:04Avionics Aircraft's Safety Study found that poor decision making seems to afflict new advanced avionics
- 6:11pilots at a rate higher than that of general aviation as a whole. The
- 6:15review of advanced avionics accidents cited in this study shows the majority are not caused
- 6:21by something directly related to the aircraft, but by the pilot's lack of experience
- 6:27and a chain of poor decisions. One consistent theme in many of the fatal
- 6:31accidents is continued VFR flight into IMC. Thus, pilot skills for normal and
- 6:40emergency operations hinge not only on mechanical manipulation of the stick and rudder, but
- 6:45also include the mental mastery of the EFD. Three key flight management skills are
- 6:50needed to fly the advanced avionics safely. Information automation, and risk nation management.
- 7:01For the newly transitioning pilot, the PFD, MFD and GPS SLANT BHF
- 7:06navigator screens seem to offer too much information presented in colorful menus and sub menus.
- 7:14In fact, the pilot may be drowning in information but unable to find
- 7:17a specific piece of information. It might be helpful to remember these systems are
- 7:23similar to computers, which store some folders on a desktop and some within a
- 7:28hierarchy. The first critical information management skill for flying with advanced avionics is to
- 7:34understand the system at a conceptual level. Remembering how the system is organized helps
- 7:41the pilot manage the available information. It is important to understanding that learning knob
- 7:46and dial procedures is not enough. Learning more about how advanced avionics systems work
- 7:51leads to better memory for procedures and allows pilots to solve problems they have not
- 7:57seen before. There are also limits to understanding. It is generally impossible to
- 8:03understand all of the behaviors of a complex avionics system. Knowing to expect surprises
- 8:09and to continually learn new things is more effective than attempting to memorize mechanical manipulation
- 8:16of the knobs. Simulation software and books on the specific system used are of
- 8:20great value. The second critical information management skill is to stop look and read.
- 8:28Pilots new to advanced avionics often become fixated on the knobs and try to
- 8:33memorize each and every sequence of button pushes, pulls, and turns. A
- 8:39far better strategy for accessing and managing the information available in advanced avionics computers is
- 8:45to stop look and read. Reading before pushing, pulling, or twisting can
- 8:50often save a pilot some trouble. Once behind the display screens on an advanced
- 8:56avionics aircraft, the pilot's goal is to meet, manage, and prioritize the
- 9:01information flow to accomplish specific tasks. Certificated flight instructors cfis, as well as
- 9:09pilots transitioning to advanced avionics, will find it helpful to corral the information flow.
- 9:15This is possible through such tactics as configuring the aspects of the PFD and
- 9:20MFD screens according to personal preferences. For example, most systems offer map orientation
- 9:26options that include north up, track up, DTK, desired track up,
- 9:33and heading up. Another tactic is to decide, when possible, how much
- 9:39or how little information to display. Pilots can tailor the information displayed to suit
- 9:45the needs of a specific flight. Information flow can also be managed for a
- 9:50specific operation. The pilot has the ability to prioritize information for a timely display
- 9:56of exactly the information needed for any given flight operation. Examples of managing information
- 10:03display for specific operation include program map scale settings for en route versus terminal area
- 10:11operation. Utilize the terrain awareness page on the MFD for a night or IMC
- 10:16flight in or near the mountains. Use the nearest airports in set on the
- 10:22PFD at night or over inhospitable terrain. Program the weather data link set to
- 10:28show echoes and met our status flags. Enhanced situational awareness. An advanced avionics
- 10:37aircraft offers increased safety with enhanced situational awareness. Although aircraft Flight manuals AFM explicitly
- 10:46prohibit using the moving map, topography to rain awareness, traffic and weather data
- 10:52link displays as the primary data source, these tools nonetheless give the pilot unprecedented
- 10:58information for ann situational awareness without a well planned information management strategy. These tools
- 11:05also make it easy for an unwary pilot to slide into the complacent role of
- 11:11passenger in command. Consider the pilot whose navigational information management strategy consists solely of
- 11:18following the magenta line on the moving map. He or she can easily fly
- 11:22into geographic or regulatory disaster if the straight line GPS course goes through high terrain
- 11:30or prohibited airspace, or if the moving map display fails. A good strategy
- 11:35for maintaining situational awareness information management should include practices that help ensure that awareness is
- 11:43enhanced by the use of automation, not diminished. Two basic procedures are to
- 11:48always double check the system and verbal call outs at a minimum ensure the presentation
- 11:54makes sense. Was the correct destination fed into the navigation system call outs,
- 12:01even for single pilot operations, are an excellent way to maintain situational awareness as
- 12:07well as manage information. Other ways to maintain situational awareness include perform verification check
- 12:15of all programming before departure. Check all information programmed while on the ground.
- 12:22Check the flight routing before departure. Ensure all routing matches the planned flight route.
- 12:28Enter the planned route and legs to include headings and leg length on a
- 12:31paper log. Use this log to evaluate what has been programmed. If the
- 12:37two do not match, do not assume the computer data is correct. Double
- 12:41check the computer entry. Verify waypoints. Make use of all onboard navigation equipment.
- 12:48For example, use VR to back up GPS and vice versa. Match
- 12:54the use of the automated system with pilot proficiency. Stay with personal limitations.
- 13:01Plan a realistic flight route to maintain situational awareness. For example, although the
- 13:07onboard equipment allows a direct flight from Denver, Colorado to Destin, Florida,
- 13:13the likelihood of rerouting around Egglin Air Force Bases airspace is high. Be ready
- 13:18to verify computer data entries. For example, incorrect keystrokes could lead to loss
- 13:26of situational awareness because the pilot may not recognize errors made during a high workload
- 13:31period. Automation management Advanced avionics offer multiple levels of automation, from strictly manual
- 13:41flight to highly automated flight. No one level of automation is appropriate for all
- 13:46flight situations, but in order to avoid potentially dangerous situations when flying with advanced
- 13:52avionics, the pilot must know how to manage the Course Deviation Indicator CDI,
- 13:58the navigation source, and the autopilot. It is important for a pilot to
- 14:03know the peculiarities of the particular automated system being used. This ensures the pilot
- 14:11knows what to expect, how to monitor for proper operation, and promptly take
- 14:16appropriate action if the system does not perform as expected. For example, at
- 14:20the most basic level, managing the autopilot means knowing at all times which modes
- 14:26are engaged and which modes are armed. To engage, the pilot needs to
- 14:33verify that armed functions, for example, navigation tracking or altitude capture engage at
- 14:39the appropriate time. Automation management is another good place to practice the call out
- 14:45technique, especially after arming the system to make a changing course or altitude.
- 14:50In advanced avionics, aircraft. Proper automation management also requires a thorough understanding of
- 14:58how the autopilot interacts with other systems. For example, with some autopilots changing
- 15:03the navigation source on the EHSI from GPS to LC or VR while the autopilot
- 15:11is engaged in NAV, the course tracking mode will cause the autopilot's NAV mode
- 15:18to disengage. The autopilot's lateral control will default to rol wing level until the
- 15:26pilot takes action to re engage the NAV mode to track the desired navigation source.
- 15:33Risk management. Risk management is the last of the three management skills needed
- 15:39for mastery of the glass flight deck aircraft. The enhanced situational awareness and automation
- 15:46capabilities offered by a glass flight deck airplane vastly expand its safety and utility,
- 15:52especially for personal transportation use. At the same time, there is some risk
- 15:58that lighter workloads could lead to complacency. Humans are characteristically poor monitors of automated
- 16:04systems. When asked to passively monitor an automated system for faults, abnormalities,
- 16:11or other infrequent events, humans perform poorly. The more reliable the system,
- 16:17the poorer the human performance. For example, the pilot only monitors a backup
- 16:22alert system, rather than the situation that the alert system is designed to safeguard.
- 16:27It is a paradox of automation that technically advanced davionics can both increase and
- 16:33decrease pilot awareness. It is important to remember that electronic flight displays do not
- 16:40replace basic flight knowledge and skills. They are a tool for improving flight safety.
- 16:45Risk increases when the pilot believes the gadgets will compensate for lack of skill
- 16:51and knowledge. It is especially important to recognize there are limits to what the
- 16:56electronic systems in any light general aviation aircraft. Do. Being pic requires sound
- 17:03adm which sometimes means saying no to a flight. Risk is also increased when
- 17:08the pilot fails to monitor the systems. By failing to monitor the systems and
- 17:14failing to check the results of the processes, the pilot becomes detached from the
- 17:18aircraft operation and slides into the complacent role of passenger in command. Complacency led
- 17:26to tragedy in a nineteen ninety nine aircraft accident in Columbia, a multi engine
- 17:32aircraft crewed with two pilots struck the face of the Andes Mountains. Examination of
- 17:37their FMS revealed they entered a waypoint into the FMS incorrectly by one degree,
- 17:44resulting in a flight path taking them to a point sixty nautical miles off their
- 17:48intended course. The pilots were equipped with the proper charts, their route was
- 17:53posted on the charts, and they had a paper navigation log indicating the direction
- 17:57of each leg. They had all the tools to manage and monitor their flight,
- 18:03but instead allowed the automation to fly and manage itself. The system did
- 18:08exactly what it was programmed to do. It flew on a programmed course into
- 18:14a mountain, resulting in multiple deaths. The pilots simply failed to manage the
- 18:18system and inherently created their own hazard. Although this hazard was self induced,
- 18:25what is notable is the risk the pilots created through their own inattention by failing
- 18:30to evaluate each turn made at the direction of automation, the pilot's maximized risk
- 18:37instead of minimizing it. In this case, a totally avoidable accident became a
- 18:41tragedy through simple pilot error and complacency. For the general aviation pilot transitioning to
- 18:48automated systems, it is helpful to note that all human activity involving technical devices
- 18:55entails some element of risk. Knowledge, experience, and mission require ernaments tilt
- 19:00the odds in favor of safe and successful flights. The advanced avionics aircraft offers
- 19:06many new capabilities and simplifies the basic flying tasks, but only if the pilot
- 19:11is properly trained and all the equipment is working as advertised. Chapter Summary.
- 19:18This chapter focuses on helping the pilot improve his or her ADM skills, with
- 19:23the goal of mitigating the risk factors associated with flight in both classic and automated
- 19:30aircraft. In the end, the discussion is not so much about aircraft,
- 19:34but about the people who fly them. End of Part seven of Chapter seventeen.
