- 0:00The paved checklist. Another way to mitigate risk is to perceive hazards by incorporating
- 0:07the paved checklist into pre flight planning. The pilot divides the risks of flight
- 0:12into four categories Pilot in Command p I C, Aircraft Environment, end External
- 0:22Pressures p a v E, which form part of a pilots decision making process.
- 0:29With the paved checklist, pilots have a simple way to remember each category
- 0:34to examine for risk prior to each flight. Once a pilot identifies the risks
- 0:39of a flight, here or she needs to decide whether the risk or combination
- 0:44of risk can be managed safely and successfully. If not, make the decision
- 0:49to cancel the flight. If the pilot decides to continue with the flight,
- 0:54he or she should develop strategies to mitigate the risks. One way a pilot
- 1:00can control the risks is to set personal minimums for items in each risk category.
- 1:06These are limits unique to that individual pilot's current level of experience and proficiency.
- 1:11For example, the aircraft may have a maximum crosswind component of fifteen knots
- 1:17listed in the Aircraft Flight Manual AFM, and the pilot has experience with ten
- 1:23knots of direct crosswind It could be unsafe to exceed a ten knot crosswind component
- 1:29without additional training. Therefore, the ten knots crosswind experience level is that pilot's
- 1:34personal limitation until additional training with a certificated Flight instructor CFI provides the pilot with
- 1:42additional experience for flying in crosswinds that exceed ten knots. One of the most
- 1:48important concepts that safe pilots understand is the difference between what is legal in terms
- 1:55of the regulations and what is smart or safe in terms of pilot experience and
- 2:00proficiency. P equals Pilot in command PIC. The pilot is one of the
- 2:07risk factors in a flight. The pilot must ask, am I ready for
- 2:12this trip in terms of experience, recency, currency, physical and emotional condition.
- 2:19The im safe checklist provides the answers A equals aircraft? What limitations will
- 2:27the aircraft impose upon the trip? Ask the following questions, is this the
- 2:32right aircraft for the flight? Am I familiar with? And current in this
- 2:38aircraft? Aircraft performance figures in the AFM are based on a brand new aircraft
- 2:45flown by a professional test pilot. Keep that in mind while assessing personal and
- 2:50aircraft performance. Is this aircraft equipped for the flight instruments, lights, navigation,
- 2:58and communications equipment adequate? Can this aircraft use the runways available for the
- 3:04trip with an adequate margin of safety under the conditions to be flown? Can
- 3:08this aircraft carry the planned load? Can this aircraft operate at the altitudes needed
- 3:15for the trip? Does this aircraft have sufficient fuel capacity with reserves for trip
- 3:22legs planned? Does the fuel quantity delivered match the fuel quantity ordered? V
- 3:29equals environment weather Weather is a major environmental consideration. Earlier, it was suggested
- 3:39pilots set their own personal minimums, especially when it comes to weather. As
- 3:45pilots evaluate the weather for a particular flight, they should consider the following.
- 3:51What are the current ceiling invisibility in mountainous terrain? Consider having higher minimums for
- 3:57ceiling invisibility, particularly if the rain is unfamiliar. Consider the possibility that the
- 4:03weather may be different than forecast. Have alternative plans, and be ready and
- 4:09willing to divert should an unexpected change occur. Consider the winds at the airports
- 4:15being used and the strength of the cross wind component. If flying in mountainous
- 4:20terrain, consider whether there are strong winds. Aloft Strong winds and mountainous terrain
- 4:26can cause severe turbulence and down drafts and be very hazardous for aircraft even when
- 4:30there is no other significant weather. Are there any thunderstorms present or forecast?
- 4:38If there are clouds, is there any icing current or forecast? What does
- 4:43the temperature? Do points spread? And the current temperature at altitude? Can
- 4:47discent be made safely all along the route? If icing conditions are encountered.
- 4:54Is the pilot experienced at operating the aircraft's de icing or anti icing equipment?
- 5:00Is this equipment in good condition and functional for what icing conditions? Is the
- 5:05aircraft rated if any terrain Evaluation of terrain is another important component of analyzing the
- 5:15flight environment. To avoid terrain and obstacles, especially at night or in low
- 5:20visibility, determine safe altitudes in advance by using the altitude shown on VFR and
- 5:28i FR charts. During preflight planning, use maximum elevation figures me efs,
- 5:34and other easily obtainable data to minimize the chances of an inflight collision with terrain
- 5:40or obstacles. Airport What lights are available at the destination and alternate airports?
- 5:49VASSI or pappy or ils glides slope guidance. Is the terminal airport equipped with
- 5:55them? Are they working? Will the pilot need to use the radio to
- 6:00activate the airport lights? Check the notices to airmen, notems for closed runways
- 6:05or airports. Look for runway or beacon lights out nearby towers, etc.
- 6:13Choose the flight route wisely. An engine failure gives the nearby airports supreme importance.
- 6:19Are there shorter or obstructed fields at the destination and or alternate airports airspace?
- 6:28If the trip is over remote areas, our appropriate clothing, water,
- 6:31and survival gear on board in the event of a forest landing. If the
- 6:36trip includes flying over water or unpopulated areas with a chance of losing visual reference
- 6:42to the horizon, the pilot must be prepared to fly IFR. Check the
- 6:47airspace in any temporary flight restriction TFRs along the route of flight. Nighttime night
- 6:56flying requires special consideration. If the trip includes flying at night over water or
- 7:01unpopulated areas with a chance of losing visual reference to the horizon, the pilot
- 7:06must be prepared to fly IFR. Will the flight conditions allow us safe emergency
- 7:13landing at night? Preflight. All aircraft lights interior and exterior for a night
- 7:18flight carry at least two flashlights, one for exterior preflight and a smaller one
- 7:25that can be dimmed and kept nearby. E equals external pressures. External pressures
- 7:32are influences external to the flight that create a sense of pressure to complete a
- 7:38flight, often at the expense of safety. Factors that can be external pressures
- 7:43include the following someone waiting at the airport for the flight's arrival, a passenger
- 7:48the pilot does not want to disappoint, the desire to demonstrate pilot qualifications,
- 7:56the desire to impress someone. Probably two most dangerous words and aviation are watch
- 8:03this, the desire to satisfy a specific personal goal get home itis, get
- 8:09their itis, and let's go itis. The pilot's general goal completion orientation,
- 8:16emotional pressure associated with acknowledging that skill and experience levels may be lower than a
- 8:22pilot would like them to be. Pride can be a powerful external factor managing
- 8:28external pressures. Management of external pressure is the single most important key to risk
- 8:35management because it is the one risk factor category that can cause a pilot to
- 8:39ignore all the other risk factors. External pressures put time related pressure on the
- 8:46pilot and figure into a majority of accidents. The use of personal standard operating
- 8:52procedures SOOPS is one way to manage external pressures. The goal is to supply
- 9:00a release for the external pressures of a flight. These procedures include, but
- 9:05are not limited, to allow time on a trip for an extra fuel stop
- 9:09or to make an unexpected landing because of weather. Have alternate plans for a
- 9:15late arrival or make backup airline reservations for must be their trips. For really
- 9:20important trips, plan to leave early enough so that there would still be time
- 9:24to drive to the destination. Advise those who are waiting at the destination that
- 9:31the arrival may be delayed, know how to notify them when delays are encountered.
- 9:37Manage passengers expectations. Make sure passengers know that they might not arrive on
- 9:43a firm schedule, and if they must arrive by a certain time, they
- 9:46should make alternative plans. Eliminate pressure to return home even on a casual day
- 9:52flight, by carrying a small overnight kit containing prescriptions, contact lens, solutions
- 9:58toiletry, or other necessities on every flight. The key to managing external pressure
- 10:05is to be ready for and accept delays. Remember that people get delayed when
- 10:09traveling on airlines, driving a car, or taking a bus. The pilot's
- 10:15goal is to manage risk, not create hazards. Refer to Figure seventeen dash
- 10:20six human behavior. Studies of human behavior have tried to determine an individual's predisposition
- 10:30to taking risk and the level of an individual's involvement in accidents. In nineteen
- 10:35fifty one, a study regarding injury prone children was published by Elizabeth Metchem Fuller
- 10:43and Helen B. Bond of the University of Minnesota. The study was comprised
- 10:48of two separate groups of second grade students. Fifty five students were considered accident
- 10:54repeaters and forty eight students had no accidents. Both groups were from the same
- 11:00school of six hundred, and their family demographics were similar. The accident free
- 11:05group showed a superior knowledge of safety, were considered industrious and cooperative with others,
- 11:11but were not considered physically inclined. The accident repeater group had better gymnastic
- 11:18skills, were considered aggressive and impulsive, demonstrated rebellious behavior when under stress,
- 11:24were poor losers, and liked to be the center of attention. One interpretation
- 11:30of this data an adult predisposition to injuries stems from childhood behavior and environment,
- 11:35leads to the conclusion that any pilot group should be comprised only of pilots who
- 11:41are safety conscious, industrious, and cooperative. Clearly, this is not only
- 11:46an inaccurate inference. It is impossible pilots are drawn from the general population and
- 11:52exhibit all types of personality traits. Thus, it is important that good decision
- 11:58making skill be taught to all pilots. Historically, the term pilot error has
- 12:05been used to describe an accident in which an action or decision made by the
- 12:09pilot was the cause or a contributing factor that led to the accident. This
- 12:15definition also includes the pilot's failure to make a correct decision or take proper action.
- 12:20From a broader perspective, the phrase human factors related more aptly describes these
- 12:26accidents. A single decision or event does not lead to an accident, but
- 12:33a series of events and the resultant decisions together form a chain of events leading
- 12:37to an outcome. In his article Accident Prone Pilots, doctor Patrick R.
- 12:43Valetti uses the history of Captain Everyman to demonstrate how aircraft accidents are caused more
- 12:50by a chain of poor choices rather than one single poor choice. In the
- 12:56case of Captain Everyman, after a year up landing accident, he became involved
- 13:01in another accident. While taxing a beach fifty eight p baron out of the
- 13:05ramp. Interrupted by a radio call from the dispatcher, every Man neglected to
- 13:09complete the fuel cross feed check before taking off. Every Man, who was
- 13:13flying solo, left the right fuel selector in the cross feed position. Once
- 13:20aloft and cruising, he noticed a right roll tendency and corrected with ailer on
- 13:24trim. He did not realize that both engines were feeding off the left wing's
- 13:28tank, making the wing lighter. After two hours of flight, the right
- 13:33engine quit when every Man was flying along a deep canyon gorge. While he
- 13:37was trying to troubleshoot the cause of the right engine's failure. The left engine
- 13:43quit. Every Man lended the aircraft on a river sand bar, but it
- 13:48sank into ten feet of water. Several years later, every Man flew at
- 13:52Havel and twin Otter to deliver supplies to a remote location. When he returned
- 13:58to home base and landed the air aircraft veered sharply to the left, departed
- 14:01the runway, and ran into a marsh three hundred and seventy five feet from
- 14:05the runway. The airframe and engines sustained considerable damage. Upon inspecting the wreck,
- 14:13accident investigators found the nosewheel steering tiller in the fully deflected position. Both
- 14:20the after takeoff and before landing checklist required the tiller to be placed in the
- 14:24neutral position. Every man had overlooked this item now is every man accident prone
- 14:33or just unlucky? Skipping details on a checklist appears to be a common theme
- 14:39in the preceding accidents. While most pilots have made similar mistakes, these errors
- 14:43were probably caught prior to a mishap due to extra margin, good warning systems,
- 14:50a sharp copilot, or just good luck. What makes a pilot less
- 14:54prone to accidents? The successful pilot possesses the ability to conson trait, manage
- 15:01workloads, monitor and perform several simultaneous tasks. Some of the latest psychological screenings
- 15:07used in aviation test applicants for their ability to multitask, measuring both accuracy as
- 15:13well as the individual's ability to focus attention on several subjects. Simultaneously, the
- 15:20FAA oversaw an extensive research study on the similarities and dissimilarities of accident free pilots
- 15:26and those who were not. The projects surveyed over four thousand pilots, half
- 15:31of whom had clean records, while the other half had been involved in an
- 15:35accident. Five traits were discovered in pilots prone to having accidents. These pilots
- 15:43have disdained toward rules, have very high correlation between accidents on their flying records
- 15:48and safety violations on their driving records. Frequently fall into the thrill and adventure
- 15:54seeking personality category, are impulsive rather the methodical and disciplined, both in their
- 16:02information gathering and in the speed and selection of actions to be taken. A
- 16:07disregard for and under utilization of outside sources of information, including copilots, flight
- 16:14attendants, flight service personnel, flight instructors, and air traffic controllers. End
