FLAIRTEM（固定回路机载瞬变电磁学）是一种地面-空中混合系统，它结合了使用一个非常大的地面发射机回路与机载接收机。该方法是1991-93年期间在澳大利亚开发的。在澳大利亚和巴布亚新几内亚（PNG）完成了对一些矿藏的初步FLAIRTEM测试调查。结果是在巴布亚新几内亚弗里达河地区的一个40吨硫化铜矿存款。模拟结果表明，FLAIRTEM方法可以有更大的灵敏度埋地导体在100米以上的深度比传统的机载系统。
FLAIRTEM (Fixed Loop AIRborne Transient Electromagnetics) is a hybrid ground-air system that combines the use of a very large ground based transmitter loop with an airborne receiver. The method was developed in Australia during the period 1991-93. Preliminary FLAIRTEM test surveys were completed in Australia and Papua New Guinea (PNG) over a number of mineral deposits. Results are presented over a 40-mt copper sulphide ore deposit in the Freida River area of PNG. Results from modelling suggests that the FLAIRTEM method could have greater sensitivity to buried conductors at depths of over 100 m than conventional airborne systems.
