rocks. Dust landings and snow landings can lead to a brownout or whiteout condition, which is the loss of the horizon reference. Disorientation may occur, leading to ground contact, often with fatal results. Taking off or landing on uneven terrain ... rocks can cause the tail rotor to strike the surface or if the skids get caught can lead to dynamic rollover. If the helicopter is heavily loaded, determine if there is sufficient power to clear the obstacles. Sometimes…

slow reactions to movements of the helicopter. 2. Failure to allow for lag in cyclic and collective pitch, which leads to overcontrolling. It is very common for a student to get ahead of the helicopter. Due to inertia, it requires ... occasional touchdown. 6. Becoming overly confident over prepared surfaces when taking off to a hover. Be aware that dynamic rollover accidents usually occur over a level surface. Hovering Turn A hovering turn is a maneuver performed at hovering height…

Helicopter Night VFR Operations While ceiling and visibility significantly affect safety in night VFR operations, lighting conditions also have a profound effect on safety. Even in conditions in which visibility and ceiling are determined to be visual meteorological conditions ... night may be compromised. The ability to discern these objects and terrain is referred to as the “seeing condition,” and is related to the amount of natural and man-made lighting available, and the contrast, reflectivity, and texture of surface…

lower the collective and check to see if the downslope skid or wheel is caught on something. Under these conditions, vertical ascent is the only acceptable method of lift-off. 12. Be aware that dynamic rollover can be experienced during ... operating from floating platforms should also exercise great caution concerning cranes, masts, nearby boats (tugs) and nets. Low-G Conditions and Mast Bumping “G” is an abbreviation for acceleration due to the earth’s gravity. A person standing…

ceiling as 7,000 feet, and the lowest visibility as 15 miles. A pilot may never experience MVFR conditions and would leave the dash in place. However, in this example and as shown in Figure 2-3, the pilot regularly ... flies in an area where normal summer flying involves hazy conditions over relatively flat terrain and is more experienced and comfortable in MVFR. The pilot used the MVFR column to record personal minimums of a 2,500-foot ceiling…
