Which of the following meals should a pilot avoid eating shortly before a flight because it tends to produce intestinal gas that expands at altitude and contains alcohol?

The most effective method of scanning for other aircraft for collision avoidance during nighttime hours is to use:

Peripheral vision by scanning small sectors and utilizing offcenter viewing.

Regularly spaced concentration on the 3-, 9-, and 12-o'clock positions.

A series of short, regularly spaced eye movements to search each 30-degree sector.

What is the definition of Time of useful consciousness?

The time where an individual can function properly, after being exposed to an inadequate supply of oxygen.

The time where an individual can function properly, after being exposed to too much carbon monoxide.

The time where an individual can remain conscious, after being exposed to an inadequate supply of oxygen.

You are landing on a downsloping runway. What should you be aware of?

You may end up making a higher approach, as you get the feeling that the aircraft is lower than it actually is.

You may end up making a lower approach, as you get the feeling that the aircraft is higher than it actually is.

You may end up making a lower approach, as you get the feeling that the aircraft is lower than it actually is.

Which visual illusion is described as perceiving a single stationary point of light against a dark background as if it were moving?

Identifying a light source on a dark background as moving despite being stationary

Feeling that we are flying too low when exposed to too much light

The sensation of vertigo that we experience when flying inside a cloud

When flying solely by reference to instruments, how should the pilot treat the balance sensations coming from the vestibular system?

We ignore the vestibular system

The pilot continuously checks the instruments to avoid possible illusions while flying IFR

We have contradictory information between what our instruments tell us and what our senses tell us

To provide the body with a rapidly available source of energy for a flight, the carbohydrates that are ingested should have which characteristic?

Must be primarily short-chain sugars

They improve the digestive process
