The air AI includes airspace adjacent to the air AO and extends into enemy
airspace. The air AI is normally much larger than the ground due to the great
distances aircraft can rapidly cover. The air AI extends upward to the maximum
service ceiling of enemy aircraft and the maximum effective altitude of enemy air
defense weapons systems. The air AI may also extend as far as enemy airfields and
to the maximum range of enemy SSM systems. Figure 7-1 shows the air AO and AI.
Figure 7-2 shows the maximum effective altitudes of major Soviet surface-to-air
missile (SAM) systems.
