I'm interested in Leeham News and Analysis. Can you explain the difference between their free and premium content, describe what their Aircraft Performance and Cost Model (APCM) offers to industry professionals, and tell me where I can purchase the 'Air Wars' book?
Navigate to the 'Subscribe' page to understand the differences between free and premium content. Navigate to the 'Aircraft Model' page to learn about APCM's capabilities. Navigate to the 'Books' page to find purchase locations for 'Air Wars'. Synthesize the gathered information to answer all three questions.
State that premium content offers detailed, independent aircraft economic analysis, trends, one-on-one interviews, and unique news, removing OEM bias, while free content covers general news, conference coverage, and links to third-party information. Describe APCM as a tool that normalizes OEM data, strips sales spin, compares over 110 aircraft types, and provides capabilities such as fuel/energy consumption benchmarking, cabin configuration and LOPA modeling, mission-level operational cost forecasting, and production cost estimation. State that 'Air Wars' is available on Amazon.com and Barnes and Noble.
