What is the proper descent procedure when cleared by ATC to descend to 8000 feet while at 15,000 feet and flying 280 knots?

The correct approach to the descent procedure involves adhering to the altitude restrictions and speed limits as set by air traffic control. When cleared to descend from 15,000 feet to 8,000 feet, it is important to manage the aircraft’s speed appropriately, especially as you approach 10,000 feet.

In this scenario, the descent is initiated at 280 knots, but upon reaching 10,000 feet, a significant regulatory requirement mandates that the aircraft should not exceed 250 knots in the descent. By first descending to 10,000 feet at the current speed before leveling off, the pilot can then reduce the speed to the maximum of 250 knots. This ensures compliance with FAA regulations regarding speed restrictions at lower altitudes, particularly in terminal airspace.

After slowing to 250 knots, the descent can continue smoothly to 8,000 feet. This method is not only compliant with air traffic control directives but also helps maintain safety and efficiency in managing the aircraft's speed as it descends through varying altitude layers.

The rationale behind the other choices involves their failure to properly address the speed restrictions associated with descending below 10,000 feet effectively. It is crucial to manage both altitude and speed in a manner that enhances safety and adheres to
