The results of measurements performed during the year 2003 onboard aircraft, mostly during regular commercial flights of the Czech Airlines (CSA) are presented. The studies were performed during more than 30 individual flights, several dosemeters and equipments were used for both neutron and non-neutron components of the onboard radiation field. CSA colleagues submitted us for all flights with navigation data necessary for the calculation of onboard aircraft crew exposure with transport codes EPCARD and CARI. Direct readings of experimental equipments were corrected on the base of the calibration in CERN high-energy radiation fields. A reasonable agreement of measured and calculated data was observed. During one of the flights, a very deep Forbush decrease occurred. The experimental results confronted with calculation permitted to obtain new view on the influence of such events on aircraft crew exposure.
本文展示了2003年在飞机上进行测量的结果，大部分测量是在捷克航空公司（CSA）的定期商业航班上进行的。这些研究在30多次单独飞行中进行，使用了几种剂量计和设备来测量飞机上辐射场的中子和非中子成分。CSA的同事为我们提供了所有航班的导航数据，以便使用EPCARD和CARI运输代码计算飞机机组人员的暴露剂量。实验设备的直接读数根据在欧洲核子研究组织（CERN）高能辐射场中的校准进行了校正。测量数据和计算数据之间观察到合理的一致性。在其中一次飞行中，发生了一次非常强烈的福布什下降。将实验结果与计算结果进行对比，有助于获得关于此类事件对飞机机组人员暴露影响的新观点。
