Final answer:
RVSM airspace is a concept used in aviation to reduce the vertical separation between aircraft, allowing for more efficient use of airspace.
Step-by-step explanation:
RVSM (Reduced Vertical Separation Minimum) airspace is a concept used in aviation to reduce the vertical separation between aircraft, allowing for more efficient use of airspace. In RVSM airspace, the standard vertical separation minimum is reduced from 2,000 feet to 1,000 feet between aircraft flying at or above FL290 (Flight Level 290).
This reduction in separation is possible due to the use of precise altitude measurement and monitoring systems known as RVSM equipment. These systems ensure accurate altitude reporting by aircraft and enable the air traffic control to maintain safe separation between them.
RVSM airspace brings several benefits, including increased airspace capacity, reduced fuel consumption, and improved flight efficiency. It allows air traffic controllers to safely handle more aircraft in a given airspace, leading to smoother and more efficient flight operations.
