On a Jepp chart, what signifies the highest obstacle?

On a Jeppesen chart, the highest obstacle is identified by a black arrow pointing to the obstacle's location. This symbol is used to indicate the position of significant terrain obstacles that could affect flight operations and safety. The design of the arrow serves to clearly highlight the obstacle's location in relation to the surrounding environment, helping pilots to remain aware of potential hazards while navigating or planning their routes.

By using this specific marker, the chart ensures that pilots can quickly recognize and prepare for any altitude restrictions that may be necessary to safely navigate in the vicinity of the highest obstacles. This attention to detail is vital for overall flight safety and navigation strategy.
