What is the terrain elevation at the obstruction located approximately 3 NM south of Lincoln Airport (LHM)?

The correct answer indicates that the terrain elevation at the obstruction located approximately 3 NM south of Lincoln Airport is 11 feet lower than the airport elevation. This implies that when evaluating the surrounding terrain and any obstructions in relation to the airport, it is crucial to know both the elevation of the airport itself and any nearby points of interest.

In flight operations, understanding terrain elevation is vital for compliance with obstacles clearance and for ensuring safe aircraft operations in the area. Ensuring that you know the specific elevations helps pilots make informed decisions regarding flight paths, approach and departure angles, as well as obstacle avoidance.

Knowing that the obstruction is 11 feet lower than the airport elevation informs the pilot that while there is an obstruction, they have some margin in terms of altitude when flying over or near the obstruction in relation to the airport's elevation. This understanding can help mitigate risks associated with terrain and potential obstructions in the vicinity of the airport.
