How can an instrument pilot best overcome spatial disorientation?

Use a very rapid cross-check.
Properly interpret the flight instruments and act accordingly.
Avoid banking in excess of 30°.

Question 15 of 30

15. Question

Abrupt head movement during a prolonged constant rate turn in IMC or simulated instrument conditions can cause

pilot disorientation.
false horizon.
elevator illusion.

Question 16 of 30

16. Question

A rapid acceleration during takeoff can create the illusion of

spinning in the opposite direction.
being in a noseup attitude.
diving into the ground.

Question 17 of 30

17. Question

An abrupt change from climb to straight-and-level flight can create the illusion of

tumbling backwards.
a noseup attitude.
a descent with the wings level.

Question 18 of 30

18. Question

A sloping cloud formation, an obscured horizon, and a dark scene spread with ground lights and stars can create an illusion known as

elevator illusions.
autokinesis.
false horizons.

Question 19 of 30

19. Question

Abrupt head movement during a prolonged constant rate turn in IMC or simulated instrument conditions can cause

Coriolis illusion.
elevator illusion.
inversion illusion.

Question 20 of 30

20. Question

The sensory system responsible for most of the illusions leading to spatial disorientation is the

visual system.
vestibular system.
postural system.

Question 21 of 30

21. Question

Without visual aid, a pilot often interprets centrifugal force as a sensation of

rising or falling.
turning.
motion reversal.

Question 22 of 30

22. Question

Pilots should take care when retrieving charts or dropped objects in the cockpit to avoid

Autokinesis.
False horizon.
Coriolis illusion.

Question 23 of 30

23. Question

While making prolonged constant-rate turns under IFR conditions, an abrupt head movement can create the illusion of rotation on an entirely different axis. This is known as

Coriolis illusion.
autokinesis.
the leans.

Question 24 of 30

24. Question

To preserve night vision, the most appropriate cockpit lighting is

Reducing the interior lighting intensity to a minimum level.
The use of regular white light, such as a flashlight, will not impair night adaptation.
Increase the interior intensity to slightly above the outside level.

Question 25 of 30

25. Question

What effect does haze have on the ability to see traffic or terrain features during flight?

Haze causes the eyes to focus at infinity, making terrain features harder to see.
The eyes tend to overwork in haze and do not detect relative movement easily.
Haze creates the illusion of being a greater distance than actual from the runway, and causes pilots to fly a lower approach.

Question 26 of 30

26. Question

Which statement is correct regarding the use of cockpit lighting for night flight?

Reducing the lighting intensity to a minimum level will eliminate blind spots.
The use of regular white light, such as a flashlight, will impair night adaptation.
Coloration shown on maps is least affected by the use of direct red lighting.

Question 27 of 30

27. Question

Which technique should a pilot use to scan for traffic to the right and left during straight-and-level flight?

Systematically focus on different segments of the sky for short intervals.
Concentrate on relative movement detected in the peripheral vision area.
Continuous sweeping of the windshield from right to left..

Question 28 of 30

28. Question

Due to visual illusion, when landing on a narrower-than-usual runway, the aircraft will appear to be

higher than actual, leading to a lower-than-normal approach.
lower than actual, leading to a higher-than-normal approach.
higher than actual, leading to a higher-than-normal approach.

Question 29 of 30

29. Question

What visual illusion creates the same effect as a narrower-than-usual runway?

An upsloping runway.
A wider-than-usual runway.
A downsloping runway.

Question 30 of 30

30. Question

Why is fatigue hazardous to flight safety?

The pilot hurries to get done in order to rest.
Fatigue may not be apparent to a pilot until serious errors are made (an impaired pilot is a dangerous pilot).
The pilot is lazy and rushes to get done quickly.
