The ability to operate out of short poorly maintained airstrips, salt pans and farm roads make it a direct competitor to helicopters in the survey environment. Its truly remarkable crash survival capability place it in a safety category unmatched by conventional survey aircraft. The cockpit area is stressed to 40g while the rest of the airframe is constructed to conventional +3.8 and  2.33 g s. This is the same approach taken by the formula one racing fraternity in making the race cars as safe as possible for the drivers. This inherent safety was the driving factor in choosing the Air Tractor as an ultra low level(10m-30m) survey platform.<br /> The AT 402-A is fitted with a version of the PT6A engine especially developed in cooperation with Air Tractor to be both efficient and reliable. The aircrafts cost/performance ratio is unmatched by competing fixed and rotary wing platforms.<br /> Certification basis for the AT 402-A : FAR 21.25 (a) (1). The aircraft meets the structural requirements of FAR 23 and the flight criteria, propulsion systems and equipment meet the requirements of Appendix B, CAM 8. The aircraft is certified in most countries of the world with large numbers operating in America, Europe, Middle East, Far East, Asia, Australia and New Zealand.<br /><br /> Due consideration was given to meeting these standards when planning the Geophysical Instrumentation installation. The structural and mechanical design was done to comply with FAR23 and the electrical systems and equipment installation were implemented to meet the CAM8 requirements. The installation has been certified by the South African Civil Aviation Authority in compliance with the requirements of FAR23 and CAM8. The quality of documentation and testing has been of an exceptionally high standard in order to take the installation design and manufacture through to the next level.

The basic rationale has been to deploy systems that are easily mobilized and that can be installed in a single day without compromising the quality of the data. To this end the complete data acquisition (DAS) system is the size of a shoe box and the bird can be dismantled and transported in a suit-case. The towed-bird configuration was opted for to allow the use of locally sourced helicopters that need not be  magnetically cleaned before using them as survey helicopters. This implies enormous mob/demob cost savings. The historical disadvantages of towed-bird systems have been eliminated by installing the DGPS receiver and an accurate motion sensor on the bird. This has proven particularly useful with the gradiometer bird in that the orientations of the sensors are measured 20 times per second and can be corrected for during data processing.<br /> <br /> </font> <font style="font-size: 9pt;
