Are some STARs and SIDs designed with noise abatement?

• A. Yes, to route aircraft away from noise-sensitive areas
• B. No, noise abatement is not considered
• C. Only for cargo airports
• D. They increase noise near communities

Answer: (A)

Noise abatement is often built into STARs and SIDs to lessen the impact of aircraft noise on nearby communities. These procedures guide pilots to routes that steer departures and arrivals away from noise-sensitive areas, often using higher initial altitudes, specific turns, and speed or climb restrictions that reduce the time spent at low altitude over populated zones. That’s why the correct choice is that they are designed to route aircraft away from noise-sensitive areas. It’s not limited to cargo airports, and the goal is not to increase noise but to minimize it where people live.
