The level of risk is measured by the number of people or resources affected (exposure), the extent of possible loss (severity), and the likelihood of loss (probability). A hazard can be a real or perceived ... morning to make a long flight. With only a few hours of sleep and congestion that indicates the possible onset of a cold, is that pilot safe to fly? Aircraft—A pilot frequently bases decisions to fly on To maintain…

  • Chapter 3: Identifying Hazards & Associated Risks › Leading Accident Causes › Identifying Hazards

    Identifying Hazards There are several ways pilots can detect hazards. Pilots should use combinations of methods to detect hazards, including the following: • Visual Observation–A pilot’s observations provide a primary means to identify hazards. For example, a pilot ... from them. A pilot who can see terrain can maneuver to avoid it. • Preflight Planning–Many hazards can be detected through preflight planning. Weather briefings identify hazards. Aircraft performance calculations, preflight inspections, and other routine procedures may identify hazards…

  • Chapter 4: Assessing Risk › Using a Risk Assessment Matrix

    runways are just long enough to accommodate the aircraft. The possibility exists for a runway overrun on each landing. Given this data, an overrun could occur sometime, and the likelihood is “occasional.” Risk Severity The following terms describe the severity ... example of the marginal runway length, an overrun could cause major damage to the aircraft and possible severe injuries, or a “critical” outcome. Using a Risk Assessment Matrix Once risk likelihood and severity have been determined, the pilot…

Preflight should be scheduled as early as possible in the flight planning sequence, preferably during daylight hours, allowing time for maintenance assistance and correction.

  • Chapter 2: Aeronautical Decision-Making › The Decision-Making Process › Estimate (the Need To React)

    Detect (the Problem) Problem detection is the first step in the decision-making process. It begins with recognizing a change occurred or an expected change did not occur. A problem is perceived first by the senses and then ... determine the nature and severity of the problem. One critical error made during the decision-making process is incorrectly detecting the problem. In the previous example, the change that occurred was a yaw. Estimate (the Need To React…

If the pilot detects a dimly lit object in a certain direction, the pilot should not look directly ... tower, aircraft, ground lights). Short stops of a few seconds in duration in each scan will help to detect the light and its movement. A pilot can determine another aircraft’s direction of flight by interpreting the position and anticollision…
