需要一种具有成本效益的航空考古方法，它既能获取考古遗址的大规模低空照片，又有能力勘测大面积地理区域，这导致了对动力降落伞（PPC）——一种超轻型飞机——作为一种考古航空侦察飞行器的评估。飞机在飞行中的合适性能是首要考虑因素，对动力降落伞的漂移、飞行稳定性和高度稳定性的评估结果令人满意。接下来，考虑了航空相机平台所需的特性，例如低速、低振动、在低空拍摄图像的能力、便携性、低成本、安全性等。动力降落伞轻松满足了每一项要求。动力降落伞使用的限制包括植被遮挡、恶劣天气和政府规定。尽管存在这些限制，动力降落伞对于航空考古学家可选择的工具而言是一种极有价值的补充。动力降落伞在路易斯安那州、密西西比州和北达科他州的遗址获取数字静态图像、数字视频和热成像方面取得了成功，这些有希望的结果使得美国和欧洲的考古学家、土地管理者及其他相关人员对这种方法的兴趣增加。版权所有（c）2005约翰威立父子有限公司
The need for a cost-effective method of aerial archaeology that could combine the ability to acquire large-scale, low-altitude photographs of archaeological sites with the capacity for surveying large geographical areas led to an evaluation of the powered parachute (PPC), a type of ultralight aircraft, as an archaeological aerial reconnaissance vehicle. The suitable performance of the aircraft during flight was the first consideration, and an assessment of drift, in-flight stability and altitude stability of the PPC proved satisfactory Next, characteristics required of an aerial camera platform, such as slow speed, low vibration, the ability to capture images at low altitudes, portability, low cost, safety and others were considered. The PPC easily fulfilled each of the requirements. Limitations on the use of the PPC include obscuring vegetation, inclement weather and government regulations. Despite the limitations, the PPC serves as an invaluable addition to the choice of options available foraerial archaeologists. The PPC has experienced success in acquiring digital still images, digital video and thermal images at sites in Louisiana, Mississippi and North Dakota, and these promising results have led to an increased interest in this approach from archaeologists, land managers and others working in the USA and in Europe.
