NAT RVSM airspace requires the holding approvals for both lateral navigation
(NAT MNPS Approval) and height keeping performance (RVSM Approval).
airspace has a base of FL 285 and a ceiling of FL 420 with 1000 ft vertical
separation applied to aircraft operating at and between FL 290 and FL 410.
and remote area RVSM applications, where continuous direct controller-pilot
communication may not always be possible, a range of contingencies have been
considered which allow independent action by flight crews, in general, they
permit crews, in exceptional circumstances, to deviate from assigned clearances
by selecting flight levels and/or tracks where other aeroplanes are least likely
to be encountered. During such deviations, crews are required to make maximum
use of aeroplane lighting and to transmit relevant information on all
appropriate frequencies, including the distress and emergency frequency. Once
contact with ATC has been re-established, the crew will be assisted and issued
with new clearances as required. Offset track procedures may be permitted if an
encounter with turbulence is considered to be due to wake vortex.
