Madrid, 19 October 2023 (ESA)

Since 2 October 2023, a process called RVSM European Restriction List (ERL) has been implemented in Spain and other European States, whereby the RVSM flight plan (FL290 – FL410) can be rejected under certain circumstances. 

Reduced Vertical Separation (RVSM) can be defined as a reduction in vertical separation between 1,000-foot flight levels FL 290 and FL 410 inclusive.
