IAA has completed advisory assignments, aircraft inspections, and current/future valuations for international banks, lessors, insurers and finance companies.  Our client base also includes private equity/hedge funds and law firms.

IAA provides aviation consulting and aircraft sourcing services based on the experience gained through years of advising institutional investors concerning manufacturer, airline and lessor credit risk, the commercial and business aircraft market in general, as well as likely future values/lease rates and trends in the aerospace industry.

William Loh has a Bachelor's Degree in Applied Mathematics from the University of Florida, and also attended Rollins College in Winter Park, Florida where he played basketball.  In 1997, he qualified as a Registered Securities Representative while working in aircraft finance at Deutsche Bank, London, and also worked in Yield Management for Lufthansa at their base in Frankfurt from 1989 to 1991.

He has invented an innovative aircraft future value/lease rate model, as well as an operating lease cash flow IRR model which is based on all of the relevant parameters.  Both of these systems have been developed in Python/Django and are available on an Internet server.

If you are investing in aircraft leasing, it is best to make sure you understand all of the lease details over the entire term, and how they can help (or hurt) your returns.  If you have been given figures by someone, it may be well worth your while to have an independent check to avoid ending up wondering what happened to that rosy deal.  This analysis can also be helpful for lender's Credit Committees to get more comfortable with downside risks using our simulation module.

Bill's knowledge of aviation and aircraft has been enhanced by ASEL and glider ratings as well as over 200 hours in airliner, fighter and helicopter flight simulators.  He's also been fortunate to have assisted Jim Matthews and the other founders of ISTAT with the creation of their first appraiser certification examinations.

International Aviation Advisors has the expertise, commitment, and independence necessary to help you avoid unpleasant surprises, and maximize your future profitability.  We can offer personalised attention from qualified senior executives, especially in these uncertain times.
