Review Exercise Motivation Describe the helicopter’s ability to operate from unprepared surfaces and sloping ground. Explain that pilots are frequently required to use this ability under operational conditions. Explain that sloping ground techniques, involving gentle and cautious control movements and are very similar for landing on any type of doubtful surface (e.g. packed snow, marshy, rocky or sandy surfaces). Airmanship ? Lookout: obstacles ? W/V ? Helicopter limitations ? Escape path Teaching Points Explain that sloping ground operations can be divided into four phases: reconnaissance planning/manoeuvring landing take-off. Reconnaissance: Explain that all landing surfaces require careful attention during landing and take-off. Extra care must be taken where the surface is likely to be soft, slippery, or where there are obstacles such as rocks or tree stumps. Describe how cross-slope landing performance is affected by cyclic control limitations and the fact that one skid hangs lower than the other at the hover. Explain that landing into wind is always desirable for helicopter handling, but that there are often occasions when the pilot must ‘trade-off’wind and slope in order to get the best compromise between the ground and helicopter limitations. Point out that, in view of the above, it is vital to make a careful assessment of the ground before attempting to land. Manoeuvring Point out that the tail assembly is particularly vulnerable during sloping ground operations. Pilots should be constantly aware of the tail rotor, particularly when making hovering turns, when landing upslope in conditions where the ground levels out behind the helicopter, or when landing downslope. Landing Describe the landing performance and limitations of the type of training helicopter being used. Describe how to land on sloping ground, as follows: Establish a steady hover/ |
