Pilot Your Dreams: Conquer the FAA Ground School Exam 2025!

When determining the altitude of an obstruction relative to a VORTAC and a specific radial, it is essential to consult appropriate aeronautical charts, particularly sectional charts or the terminal area chart for the region. The Savannah VORTAC provides navigational assistance to pilots, and obstructions within close proximity to it can pose flight hazards.

In this context, determining the altitude involves identifying the elevation of the obstruction as indicated on these charts. The selected answer of 454 feet MSL (Mean Sea Level) reflects the actual elevation of the specific obstruction located on the 009° radial at a distance of 11 nautical miles from the VORTAC. This is established from data provided by the Federal Aviation Administration or other relevant aviation resources, which regularly update and maintain accurate information about such crucial geographical features.

The other options represent altitudes that do not correspond with the data provided for that specific location. In aviation, precise altitude information is critical for ensuring safe navigation and avoiding potential conflicts with various terrain features and other aircraft.
