The danger of spatial disorientation during flight in poor visual conditions may bereduced by
-
(1) shifting the eyes quickly between the exterior visual field and the instrument panel.
-
(2) having faith in the instruments rather than taking a chance on the sensory organs.
-
(3) leaning the body in the opposite direction of the motion of the aircraft.
Correct Answer
A. (2) having faith in the instruments rather than taking a chance on the sensory organs.Explanation
During flight in poor visual conditions, pilots may experience spatial disorientation, which is the inability to accurately perceive one's position, motion, or attitude in space. Shifting the eyes quickly between the exterior visual field and the instrument panel (option 1) can actually exacerbate spatial disorientation as it can confuse the brain even more. Leaning the body in the opposite direction of the motion of the aircraft (option 3) is also not an effective method to reduce spatial disorientation. The best approach is to rely on the instruments (option 2) as they provide accurate and reliable information about the aircraft's position and motion, minimizing the risk of spatial disorientation.Rate this question:

In an unpressurised aircraft, at high altitudes the amount of oxygen that diffuses acrossthe lung membranes into the blood is
-
(1) decreased because of the low partial pressure of oxygen.
-
(2) decreased because of the lower temperatures.
-
(3) unchanged to that at sea level.
Correct Answer
A. (1) decreased because of the low partial pressure of oxygen.Explanation
At high altitudes, the air pressure decreases, resulting in a lower partial pressure of oxygen. The partial pressure of a gas determines the concentration gradient for diffusion, and a lower partial pressure means there is less oxygen available to diffuse across the lung membranes into the blood. Therefore, the amount of oxygen that diffuses into the blood is decreased in an unpressurized aircraft at high altitudes.Rate this question:

(1) Recommend taking medication to prevent motion sickness.
-
(2) Lower her/his head, shut her/his eyes, and take deep breaths.
-
(3) Avoid unnecessary head movement and to keep her/his eyes on a point outside the aircraft.
Correct Answer
A. (3) Avoid unnecessary head movement and to keep her/his eyes on a point outside the aircraft.Explanation
Motion sickness is caused by a conflict between the visual and vestibular systems. By avoiding unnecessary head movements and keeping the eyes focused on a point outside the aircraft, the pilot can reduce the conflicting sensory inputs that contribute to motion sickness. This helps to stabilize the visual field and provide a consistent reference point, reducing the symptoms of motion sickness. Medication can be an option, but it may have side effects that can affect the pilot's performance, so it is not the first recommendation. Lowering the head and shutting the eyes may provide temporary relief but does not address the underlying cause of motion sickness.Rate this question:

(3) Recognizing the invulnerability of the situation.
Correct Answer
A. (2) Recognizing hazardous thoughts.Explanation
The first step in neutralizing a hazardous attitude in the aeronautical decision making process is recognizing hazardous thoughts. This means being aware of any negative or irrational thoughts that may lead to unsafe behavior or decision-making. By recognizing these thoughts, pilots can take proactive steps to address and counteract them, ensuring that they make rational judgments and maintain a safe and responsible attitude while flying.Rate this question:

The most effective method of scanning for other aircraft for collision avoidance duringdaylight hours is to use
-
(1) regularly spaced concentration on the 3-, 9-, and 12-o'clock positions.
-
(2) a series of short, regularly spaced eye movements to search each 10-degree sector.
-
(3) peripheral vision by scanning small sectors and utilizing off-center viewing.
Correct Answer
A. (2) a series of short, regularly spaced eye movements to search each 10-degree sector.Explanation
The most effective method of scanning for other aircraft for collision avoidance during daylight hours is to use a series of short, regularly spaced eye movements to search each 10-degree sector. This method allows for a systematic and thorough search of the airspace, ensuring that no aircraft are missed. By scanning in small sectors and utilizing off-center viewing, pilots can effectively use their peripheral vision to detect any potential threats. This method is more efficient than concentrating on specific clock positions, as it covers a wider area and reduces the chances of overlooking an aircraft.Rate this question:

What often leads to spatial disorientation or collision with ground/obstacles when flyingunder Visual Flight Rules (VFR)?
-
(1) Duck-under syndrome.
-
(2) Continual flight into instrument conditions.
-
(3) Getting behind the aircraft.
Correct Answer
A. (2) Continual flight into instrument conditions.Explanation
Continual flight into instrument conditions often leads to spatial disorientation or collision with ground/obstacles when flying under Visual Flight Rules (VFR). This means that the pilot continues to fly into weather conditions where visibility is reduced or obscured, relying solely on instruments for navigation and control. Without proper training and proficiency in instrument flying, pilots may become disoriented and lose situational awareness, increasing the risk of collision with the ground or obstacles.Rate this question:

What is the antidote when a pilot has a hazardous attitude, such as "Antiauthority"?
-
(1) Rules do not apply in this situation.
-
(2) I know what I am doing.
-
(3) Follow the rules.
Correct Answer
A. (3) Follow the rules.Explanation
The antidote for a pilot with a hazardous attitude of "Antiauthority" is to follow the rules. This means that the pilot should recognize the importance of adhering to established procedures and regulations, rather than disregarding them. By following the rules, the pilot can ensure safety and prevent any potential risks or accidents that may arise from a rebellious or non-compliant mindset.Rate this question:

What is the antidote when a pilot has a hazardous attitude, such as "Macho"?
-
(1) It will not happen to me.
-
(2) It can not be that bad.
-
(3) It could happen to me.
Correct Answer
A. (3) It could happen to me.Explanation
The antidote for a hazardous attitude like "Macho" is recognizing that the same negative outcome could happen to oneself. This attitude shift helps to prevent overconfidence and encourages pilots to take necessary precautions and avoid risky behavior.Rate this question:

An illusion, that an aircraft is at a higher altitude than it actually is, is produced by
-
(1) atmospheric haze.
-
(2) upsloping terrain.
-
(3) downsloping terrain.
Correct Answer
A. (2) upsloping terrain.Explanation
Upsloping terrain can create an illusion that an aircraft is at a higher altitude than it actually is because as the aircraft approaches the upward slope, the ground appears to rise, giving the impression of increased altitude. This can be misleading for pilots, as they may think they are higher than they actually are, leading to potential errors in navigation and landing.Rate this question:

The positive three-step process in the exchange of flight controls between pilots includesthese verbal steps: (a) You have the flight controls, (b) I have the flight controls, and (c)
-
(1) You have the flight controls.
-
(2) I have the aircraft.
-
(3) I have the flight controls.
Correct Answer
A. (1) You have the flight controls.Explanation
The correct answer is (1) You have the flight controls because it is the first step in the positive three-step process of exchanging flight controls between pilots. This step establishes clear communication and ensures that both pilots are aware of who has control of the aircraft. The other options, (2) I have the aircraft and (3) I have the flight controls, are not part of the standard verbal steps in the exchange process.Rate this question:

What is the antidote when a pilot has the hazardous attitude of "Invulnerability"?
-
(1) It can not be that bad.
-
(2) It could happen to me.
-
(3) It will not happen to me.
Correct Answer
A. (2) It could happen to me.Explanation
The correct antidote for the hazardous attitude of "Invulnerability" is to acknowledge that the same negative outcomes that can happen to others can also happen to oneself. By recognizing that one is not immune to accidents or mistakes, a pilot can adopt a more cautious and responsible mindset, which is crucial for ensuring safety in aviation.Rate this question:
