Aircraft Safety Zones
Per Air Force regulations, airfield safety zones are recommended to assist
communities in developing land uses compatible with airfield operations and
protect the health and safety of its citizens. The safety zones are referred to
as Clear Zones (CZs) and Accident Potential Zones (APZs) I and II. The safety
zones are illustrated on Figure 11. The Air Force has identified APZs and CZs
at each end of the runways based on historical data for aircraft mishaps.
The CZ begins at the end of each runway and is the area where mishap
involving aircraft operations are most likely to occur. Because of this,
development is completely restricted in the CZ. The APZ I begins at the end
of each CZ and typically experiences fewer mishaps than the CZ. Limited
development is permitted in the APZ I. The APZ II begins at the end of each
APZ I and typically experiences the least amount of accidents of all the safety
zones. Development is least restricted in the APZ II due to the reduced risk of
accidents.
