Answer 1

Answer:

Vertical separation is achieved by requiring aircraft to use a prescribed altimeter pressure setting within designated airspace, and to operate at different levels expressed in terms of altitude or flight level.

ICAO specify minimum vertical separation for IFR flight as 1000 ft (300 m) below FL290 and 2000 ft (600 m) above FL290, except where Reduced Vertical Separation Minima (RVSM) apply. Most national authorities follow a similar rule, but may specify a different level at which the rule changes.
