Important Standing Committees

• Standing committees handle the normal course of
  activity (non-technical) for AIAA. There are 20
  Standing committees which report through various
  chains at the board of director level. Several
  of the standing committees that GTTC interacts
  with more frequently are described in the
  following pages (source AIAA website).

13
Important Standing Committees
Academic Affairs Committee Works closely with
educational institutions and appropriate
accrediting agencies to encourage high standards
of technical education. Staff Contact Stephen

professionals to expand their horizons and grow
in the aerospace environment. Provides assistance
to members on career planning and growth
including engineering registration activities.
Develops and disseminates information on industry
trends relevant to the work force. Staff Contact
Karen Thomas Finance Committee Develops and
recommends policies and procedures concerning
AIAA's financial affairs and activities. The
ideal member on this committee would possess
experience in business management, financial
operations, banking or long-range strategic
planning. Membership on this committee represents
a cross-section of AIAA's government, academia,
or industry constituency as well as liaisons from
other standing committees. Staff Contact David
