Flying in a crosswind that could lead to loss of tail rotor effectiveness. 8. Excessive tail-low attitudes ... Failure to maintain alignment with direction of travel. Surface Taxi A surface taxi is used to minimize the effects of rotor downwash in wheel-type helicopters. [Figure 9-11] Surface taxiing in skid type helicopters is generally not recommended…

Using the PAVE Checklist to Identify Hazards As described in Chapter 1, the PAVE checklist provides a means to identify hazards using four convenient hazard “buckets.” Using all four checklist categories before a flight captures most hazards normally encountered. This ... section discusses hazards associated with each category. Pilot Hazards “P” hazards can be classified in terms of both capability and aeromedical factors as follows: 1. Qualification–Does the pilot possess the appropriate pilot certificate, category, class, and type rating needed…

hazardous attitude. Most pilots sincerely believe that they will respond to hazards appropriately and take actions necessary to avoid accidents. However, a pilot’s attitude affects perception of hazards, the analysis of the potential threat, and performance of an appropriate ... response. Since attitude influences behavior, pilots should consider their own attitude and the antidote to any hazardous attitude. [Figure 3-2] The pilots in the two fatal accidents described above exhibited several of these hazardous attitudes. If they had recognized…

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 ... safe distance 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…

Hazard and Risk Two defining elements of ADM are hazard and risk. Hazard is a real or perceived condition, event, or circumstance that a pilot encounters. When faced with a hazard, the pilot makes an assessment of that hazard based ... upon various factors. The pilot assigns a value to the potential impact of the hazard, which qualifies the pilot’s assessment of the hazard—risk. Therefore, risk is an assessment of the single or cumulative hazard facing a pilot; however…

Following this general procedure of fitting airspeed and rotor rpm to existing conditions, a pilot can achieve approximately the same glide angle in any set of circumstances, and thereby estimate the touchdown point accurately. Figure 11-1. During an autorotation ... upward flow of relative wind permits the main rotor blades to rotate at their normal speed. In effect, the blades are “gliding” in their rotational plane. It is important that pilots experience autorotations from various airspeeds. This provides better understanding…
