Aircraft Monitor is the platform of Shannon Ackert — aircraft economics educator, author, and aviation finance executive with more than two decades of experience spanning flight test engineering, airline operations, and commercial aircraft leasing.

Its mission is to advance understanding of aircraft economics through education, analysis, and practical tools. The site serves aviation professionals involved in aircraft investment, leasing, fleet planning, financing, and maintenance, with a focus on making complex technical and financial concepts accessible, relevant, and decision-useful.

Here you will find my books, including Airliner Performance: Insights for Aviation Business Professionals, along with industry reports on maintenance economics, aircraft valuation, performance, and leasing practices, as well as interactive tools for exploring aircraft economics and performance characteristics.
