English Abstract In 1989 the NASA High Speed Research Program (HSRP)
started, brought on by an increasing commercial interest in supersonic civil
aircraft. In the HSRP framework research on the effects of supersonic
exhaust on the global atmosphere is performed. In particular the possible
decline of the stratospheric ozone layer induced by NOx from aircraft is
studied in a subproject entitled "the Atmospheric Effects of Stratospheric
Aircraft (AESA)". The authors of this report visited the second annual
meeting of the HSRP/AESA project in Virginia Beach, USA (17 to 22 May 1992).
The current report presents the state - of the - art on research on effects
of stratospheric aircraft emissions as presented during different
sessions.
