There are two common scanning methods:
Left to right and back again.
•
Top to bottom and bottom to top.
When scanning,
o not look directly at the horizon; look above it. Move head
from side to side and keep eyes fixed. This will give any stationary objects in
the field of vision the appearance of
moving and make them easier to see.
One technique is to scan in small steps of about 10°

team coordination can:
Control human error. • Manage safety risks. • Provide directions for continuous improvement in team performance.

Leadership Mission Analysis Adaptability and Flexibility Situation Awareness Decision-Making Communication Assertiveness
Four Rules
of Risk
Management
Rule #1 Integrate risk management into mission planning and execution Rule #2 Accept no unnecessary risks Rule #3 Make risk decisions at the appropriate level. Many times mishaps occur because the level of risk is not perceived by an individual Rule #4 Accept risks if benefits outweigh costs. Elimina ting unnecessary risk leaves risk that is either acceptable or unacceptable for mission accomplishment.
