Setup and application of the helicopter taking off and landing point in airborne geophysical survey

In the airborne geophysical survey,the survey results acquired by the helicopter are recognized in geological industry because of the advantages of mobility, hedgehopping and contour flying. But the poor endurance of the helicopter is the primary problem during the airborne geophysical survey. Establishing a temporary taking off and landing point for the helicopter is the best way to solve this problem. After Summarizing the setup principles of the temporary taking off and landing point of the helicopter, the authors explained the methods of setting up the temporary taking off and landing point and the survey efficiency of the helicopter through a concrete example. The method has highly promoted the flying efficiency, expanded the survey range and reduced the survey cost.
