What does FAR Par 91.117 specify regarding airspeed limits?

FAR Part 91.117 specifically addresses the limitation of airspeeds at various altitudes to ensure safe operations within controlled airspace. This regulation defines certain maximum airspeeds, particularly pertinent when flying below specific altitudes, such as 10,000 feet MSL (Mean Sea Level), and around congested areas. By establishing these limits, the regulation aims to mitigate the risks associated with high-speed flight in environments where aircraft density may be greater, helping to protect both pilot and aircraft safety.

The regulation's focus on altitude-based speed limits is crucial for avoiding excessive speeds that could lead to more difficult handling characteristics, increased wear and tear on the aircraft, or safety hazards in busy air traffic areas. This fundamental aspect of operational safety is key to understanding why the correct choice highlights the maximum airspeed for altitudes.
