Aircraft and Aerial Warfare Manual
From the back cover:
What would be an aircraft pilot without his aircraft? The Tactical Support: Aircraft & Aerial Warfare manual, the first book in the Tactical Support series, covers everything not included in the rulebook, from air war tactical rules (movement, special maneuvers, altitude) to dogfighting (one-on-one aircraft combat). It also includes all the necessary aircraft design and maintenance rules, new weapons, new perks and flaws as well as twenty sample designs from the North, the South, and the Badlands. Lastly the book includes stock NPCs that can be used to populate airbases.
