AS 121 Exam 5 ACTUAL QUESTIONS
AND CORRECT ANSWERS
A sloping cloud formation, an obscured horizon, and a dark scene spread with ground lights and stars
can create an illusion known as - CORRECT ANSWER false horizons.
A pilot is more subject to spatial disorientation if - CORRECT ANSWER body signals are used
to interpret flight attitude.
Which technique should a pilot use to scan for traffic to the right and left during straight and-level
flight? - CORRECT ANSWER Systematically focus on different segments of the sky for short
intervals.
To preserve night vision, the most appropriate flight deck lighting is - CORRECT ANSWER
reducing the interior lighting intensity to a minimum level.
What effect does haze have on the ability to see traffic or terrain features during flight? - CORRECT
ANSWER Haze creates the illusion of being a greater distance than actual from the runway,
and causes pilots to fly a lower approach.
An abrupt change from climb to straight-and-level flight can create the illusion of - CORRECT
ANSWER tumbling backwards.
The sensations which lead to spatial disorientation during instrument flight conditions - CORRECT
ANSWER must be suppressed and complete reliance placed on the indications of the flight
instruments.
You are most likely to experience somatogravic illusion during - CORRECT ANSWER rapid
acceleration on takeoff.
Why is fatigue hazardous to flight safety? - CORRECT ANSWER Fatigue may not be apparent
to a pilot until serious errors are made (an impaired pilot is a dangerous pilot).
