The International Society of Transport Aircraft Trading (ISTAT) is a non-profit society whose members have common interests in the manufacture, purchase, brokerage, leasing, maintenance and appraisal of transport aircraft. International in structure, it is self-supporting and unaffiliated. Within ISTAT is a core group of professional aircraft appraisers who work cooperatively for the elevation of the appraisal profession within the world aviation community.
Each ISTAT member, who has satisfactorily demonstrated that he/she is qualified to appraise airline transport aircraft, has been granted the right to use one of the professional designations established by ISTAT. The use of such designations is predicated upon Society criteria: written examinations, submission of representative appraisal reports, full-time valuation experience, personal background check and participation in the Society's program of ongoing education.
Within ISTAT is a core group of professional aircraft appraisers who work cooperatively for the elevation of the appraisal profession within the world aviation community. The ISTAT Appraisers’ Program has established four professional status categories:
These professional status categories are awarded to individuals, not to corporations or other business organizations. Only Senior Appraisers may use the designation “ISTAT” after their names. An Appraiser Fellow may use the designation “FISTAT.” The category of “Candidate” is established to formalize the status of applicants wishing to join the program.
Appraiser status – requires a minimum of five years employed full time in aviation-related business, of which no less than two years shall have been spent in accomplishing aircraft appraisals.
Senior Appraiser status – requires a minimum of seven years employed full–time in aviation-related business, of which no less than six years shall be spent in accomplishing aircraft appraisals.
Appraiser Fellow status – is an honorary designation, and may be bestowed by the Appraisers’ International Board of Governors (IBG) on a Senior Appraiser who has rendered outstanding service to the appraisal profession and the Society.
Appraiser Emeritus – is an honorary designation, bestowed by the IBG on a Senior Appraiser, or Appraiser Fellow, for outstanding service to the Appraisers’ Program and the Society. The designation is not contingent upon remaining a member of ISTAT if the member is retired, incapacitated or deceased.
