FAA Visual Scanning and Collision Avoidance

Hint

Answer

Relationship between a pilot's physical condition and vision. (checklist)

Environmental Conditions that Degrade vision

 

 

 

 

Vestibular Illusions

~

Caused by abrupt correction of a bank, undetected by pilot

the illusion of moving around a different axis

An observed loss of altitude during a constant rate, coordinated turn that ceases stimulation of pilot's motion sensing system feeling like a descent with wings level

Rapid acceleration can create a nose-up illusion. Rapid deceleration can create a nose-down illusion

Change from climb to straight-and-level flight can create the illusion of tumbling backwards

An updraft can create a nose-up illusion; a downdraft a nose-down illusion

Visual Illusions

~

sloping clouds, obscured horizon, and ground lights can provide a

In the darkness, a stationary light will appear to move after being stared at for a while

A narrower runway can make the aircraft seem higher than normal; wider makes the aircraft seem lower than normal

Upsloping runway can make you think you're higher than actual, downsloping can make you think you're lower than actual

In the absence of ground features, the aircraft can appear to be higher than usual

Atmospheric illusions

~

Fog penetration can make you think you're

haze can make you think you're ____ than you actually are

rain can make you think you're ____ than you actually are

Lights in a straight line can create the illusion of being closer than actual

Pilots must always be vigilant for other traffic (concept)

Proper visual scanning procedure

The most amount of time spent looking in the cabin. (%)

Always clear the area before any maneuver

~

If you can't see around a doorpost in the aircraft you should

If the wings are in the way of clearing an area

The faster relative speeds between aircraft the more likely their will be a

Where aircraft cluster, like airports, VORs, airways, collision risk ____
