What is the scale of a VTA chart?

The correct answer is that the scale of a VTA (VFR Terminal Area) chart is 1:250,000. VTA charts are specifically designed for use around busy terminal areas, providing pilots with detailed information that is crucial for navigation at lower altitudes. The 1:250,000 scale allows for a more detailed depiction of features important for flying in and around airports, as it includes information such as airspace boundaries, controlled airspace, and landmarks which help in visual navigation.

The choice of this scale provides a balance between detail and coverage; it allows pilots to see extensive areas with sufficient detail for safe navigation and situational awareness during approaches and departures. Charts at larger scales, like 1:500,000 or 1:1,000,000, would not offer the level of detail needed for operations in these congested areas, while a scale of 1:100,000 would yield an excessively detailed view that could make it harder to orient oneself over larger geographical regions. Therefore, 1:250,000 is optimal for the intended purpose of VTA charts.
