1.6.1 Aircraft Specifications/Requirements for Military Aircraft Case Studies
This extended section of the book can be found on the Web at www. cambridge .org/Kundu and outlines specifications for introductory classroom work on military aircraft design (e. g., the Advanced Jet Trainer).

be unmonitored
|
|
Flight performance
|
Near-steady-state operation and

scheduled; gentle maneuvers
