What altitude provides a vertical separation allowance in RVSM airspace?

In RVSM (Reduced Vertical Separation Minimum) airspace, the standard vertical separation requirement is 1,000 feet. This means that aircraft flying at different altitudes must be separated by this specific amount to ensure safe and efficient air traffic management. The implementation of RVSM allows for this decreased separation, optimizing the use of available airspace, particularly at higher altitudes where air traffic tends to be busier.

The 1,000 feet separation allows for a more efficient use of airspace, especially in areas where air traffic is dense. By reducing the vertical separation from the traditional 2,000 feet to 1,000 feet in RVSM airspace, air traffic controllers can accommodate more aircraft at varying altitudes without compromising safety. This is achieved through precise navigation and performance standards that RVSM-compliant aircraft must meet.

In contexts outside RVSM, altitudes may have different separation standards, hence why other altitude options do not fit the specific requirements of RVSM airspace separation allowances.
