Which of the following charts does NOT contain a legend but uses the same symbols found on Low/High Altitude En Route charts?

The correct answer indicates that IFR Area Charts do not contain a legend while still utilizing the same symbols found on Low/High Altitude En Route charts. This is significant because legends are typically provided in other types of charts to assist pilots in understanding various symbols, but IFR Area Charts stand out by omitting this feature, relying instead on the pilots’ familiarity with the established symbols from the en route charts.

Tactical Air Navigation Charts (TACs) and Sectional Charts include legends to explain the symbols and information presented, allowing for clarity and ease of use, particularly for pilots who may not be as familiar with the symbols. Airport-specific charts also tend to have legends as they provide crucial localized information, including airport facilities, safety features, and navigation aids. The IFR Area Charts, however, expect users to be adept at reading charts without the need for additional explanatory information, reflecting a more advanced level of navigation skill among their intended users.
