What altitudes are acceptable when transitioning from South Mustang to North Mustang along the Intracoastal Waterway?

The correct choice of 3,500' MSL or 5,500' MSL reflects the altitude levels established for transitioning between South Mustang and North Mustang along the Intracoastal Waterway, which are aligned with air traffic regulations and safe operating procedures. During these transitions, these altitudes help to ensure separation from ground obstacles and traffic while providing adequate buffer zones for aircraft operations.

When aircraft are flying in this particular area, it is important for them to remain within the specified altitudes to avoid interference with other flight operations and to maintain safe vertical separation from terrain and other airspace users, especially given the potential for traffic both on the waterway and in the air.

The other altitude options provided are either too low or too high for this specific route, making them unsuitable for safe and compliant flight operations in this context.
