those activities, or both.

(b) The vertical limits of special use

airspace are measured by designated
altitude floors and ceilings expressed
as flight levels or as feet above mean
sea level. Unless otherwise specified,
the word ‘‘to’’ (an altitude or flight
level) means ‘‘to and including’’ (that
altitude or flight level).

use airspace are measured by bound-
aries described by geographic coordi-
