Aircraft are often parked here for pre-flight inspections, refueling, or minor repairs.

An Alpha Ramp is a fundamental tool in digital visual media. By mathematically manipulating opacity values across a surface, it allows designers and engineers to create seamless integration between layers, realistic soft-edged objects, and intuitive user interfaces. alpha ramp

The slope of the ramp ($S$) in the event window $[T_start, T_event]$: $$S = \frac\overline\alpha T event - \overline\alpha T startT_event - T_start$$ Aircraft are often parked here for pre-flight inspections,
