- Base rate — every Federal Contract Tower contract carries a US Department of Labor wage determination: a county-level minimum for tower controllers, tied to federal GS-10 locality pay. At union towers the collective bargaining agreement governs pay instead, and the newest publicly released figure is shown; est. means the published figure is carried forward using only raises documented in the agreement itself.
- Health & welfare — a required fringe paid on top of the wage (the negotiated rate where the agreement sets one, otherwise the current DOL rate), payable as benefits or cash for up to 40 hours per week.
