Scanning and collision avoidance Flashcards
When viewed in dim illumination, the small print and colors on aeronautical charts can become…what?
Unreadable
Excessive illumination can produce… what?
Glare and temporary blindness.
Sunglasses used by pilots should absorb at least a)_______ percent of visible light and all b)______ equally, with negligible image c)________ from refractive and prismatic errors.
A. 85%
B. Colors
C. Distortion
The possibility of a pilot spotting a potential collision threat increases with…what?
The time spent looking outside the airplane.
Effective scanning is accomplished with a series of short, regular spaced eye movements not to exceed a)________, and each area should be observed for at least c)_______ to enable detection.
A) 10 degrees
B) 1 second
What process could the pilot adopt in scanning?
Using a scanning pattern that goes from the cockpit, outside along the left wing to the wingtip, then to the first scanning area for traffic, then after all the traffic scanning areas, back along the right wing to inside the cockpit.
What can be said if another aircraft is seen in the distance below the horizon line?
The other aircraft is probably flying at a lower altitude than you are.
Which aircraft is most likely to be on a collision course with your airplane?
An aircraft that appears to have no relative motion vertically or horizontally, but increases in size.
Dirty or bug-smeared windshields greatly _______ the ability of pilots to see other aircraft and should be cleaned before flight.
Obstruct, interfere etc.
Before taking the runway for takeoff, a pilot should consider performing clearing turns or on the ground in order to
Scan the approach areas for possible landing traffic.
For collision avoidance, how should a VFR pilot, flying conditions of good visibility, execute climbs and descents?
The pilot should execute gentle banks, left and right, to permit continuous visual scanning of the airspace.
Why might period of sustained straight and level flight be occasionally broken with clearing turns?
To permit visual scanning of the airplane’s blind spots.
Why should pilots avoid entry into an airport traffic pattern while descending?
Two of the biggest blind spots for the airplanes are directly above and below and the aircraft could be descending atop another aircraft in traffic pattern.
To instill a habit of vigilance and safety during maneuvering, pilots undergoing flight instruction should be requested to… what?
Verbalize clearing procedures.
What are the recommended standard procedures for collision avoidance while turning?
Low wing: momentarily lower the wing in the direction you are trying to turn.
High wing: momentarily raise the wing in the direction you are trying to turn.
