Final answer:
Sectional charts use symbols to represent various radio aids to navigation.
Step-by-step explanation:
Sectional charts used in aviation contain various symbols to represent different navigational aids. When it comes to radio aids to navigation, several symbols are used on sectional charts to indicate the presence and type of such aids.
For example, the symbol VOR/DME represents a Very High Frequency Omni-Directional Range combined with Distance Measuring Equipment. The symbol NDB represents a Non-Directional Beacon, which is another type of navigational aid. In addition, symbols like TACAN, VORTAC, and ILS are used to denote Tactical Air Navigation, VOR & TACAN combined, and Instrument Landing System, respectively.
These symbols provide pilots with valuable information about the available radio aids to navigation, helping them navigate and safely reach their destinations.
