Dose measurements at aviation altitudes require instruments which are able to measure the dose contribution of all field components. TEPC are well suited for this task. The results of this work show that the mean quality factors obtained by using a TEPC are independent of the altitude, at least at altitudes between FL300 and FL400, but show a significant dependence on the vertical cutoff rigidity.
