Which of the following is NOT a common hazard associated with urban air mobility flights?

High altitude wind shear is considered less relevant to the common hazards associated with urban air mobility flights because these flights typically operate at lower altitudes than traditional aircraft. Urban air mobility often takes place in densely populated areas where the flight paths are usually under 1,000 feet, and the typical operational environment does not extend into the altitudes where severe wind shear is a significant concern.

In contrast, bird strikes, electrical interference, and ground obstacles are all pertinent hazards in urban environments. Bird strikes can occur due to the proximity of flight paths to habitats where birds congregate. Electrical interference can arise from urban infrastructure, including power lines and communication towers, which are prevalent in city settings. Ground obstacles are a consistent concern due to buildings, trees, and other structures that can obstruct flight paths in urban areas.

This context clarifies why high altitude wind shear does not fit the profile of urban air mobility hazards when compared to the other options.
