FAA Ground School Practice Test

How high is the obstacle on the northeast side of Airpark East Airport when considering clearance requirements?

1. 773 ft MSL

2. 873 ft MSL

3. 973 ft MSL

4. 1,073 ft MSL

The correct answer is: 973 ft MSL

When determining the height of an obstacle in relation to clearance requirements, it's essential to consider the specific obstacle height alongside the airport's elevation and any relevant regulations regarding obstacle clearance. In this context, the option of 973 feet MSL (Mean Sea Level) is likely based on the calculations involving the airport's elevation and the required obstacle clearance standards set by the FAA. These standards ensure that aircraft maintain safe clearance from obstacles during takeoff, landing, and flight paths. For instance, if the airport elevation is relatively lower than 973 feet, that height would ensure compliance with the required safety margins. This includes factors like the slope of the approach and climb-out paths, which are critical for preventing accidents. Without knowing the exact elevation of Airpark East Airport, it's reasonable to conclude that 973 feet MSL reflects a clearance height that adheres to safety guidelines, ensuring that aircraft can operate safely around the airport without encountering the specified obstacle.
