IMPLEMENTING THE DECISION AND EVALUATING THE OUTCOME
Although a decision may be reached and a course of action implemented, the decision-making process is not complete. It is important to think ahead and determine how the decision could affect other phases of the flight. As the flight progresses, you must continue to evaluate the outcome of the decision to ensure that it is producing the desired result.
As you make your turn to the downwind, the airspeed drops nearly to zero, and the helicopter becomes very difficult to control. At this point, you must increase airspeed in order to maintain translational lift, but since the CG is aft of limits, you need to apply more forward cyclic than usual. As you approach the landing zone with a high rate of descent, you realize that you are in a potential settling-with-power situation if you try to trade airspeed for altitude and lose ETL. Therefore, you will probably not be able to terminate the approach in a hover. You decide to make as shallow of an approach as possible and perform a run-on landing.
The decision making process normally consists of several steps before you choose a course of action. To help you remember the elements of the decision-making process, a six-step model has been developed using the acronym “DECIDE.” [Figure 14-2]
 
 

 
RISK MANAGEMENT
During each flight, decisions must be made regarding events that involve interactions between the four risk elements—the pilot in command, the aircraft, the environment, and the operation. The decision-making process involves an evaluation of each of these risk elements to achieve an accurate perception of the flight situation. [Figure 14-3]
One of the most important decisions that a pilot in command must make is the go/no-go decision. Evaluating each of these risk elements can help you decide whether a flight should be conducted or continued. Let us evaluate the four risk elements and how they affect our decision making regarding the following situations.
Pilot—As a pilot, you must continually make decisions about your own competency, condition of health, mental and emotional state, level of fatigue, and many other variables. For example, you are called early in the morning to make a long flight. You have had only a few hours of sleep, and are concerned that the congestion you feel could be the onset of a cold. Are you safe to fly?
Aircraft—You will frequently base decisions on your evaluations of the aircraft, such as its powerplant, performance, equipment, fuel state, or airworthiness. Picture yourself in this situation: you are en route to an oil rig an hour’s flight from shore, and you have just passed the shoreline. Then you notice the oil temperature at the high end of the caution range. Should you continue out to sea, or return to the nearest suitable heliport/airport?
Environment—This encompasses many elements not pilot or aircraft related. It can include such factors as weather, air traffic control, navaids, terrain, takeoff and
