The rods in the retina are used for night vision. Because they are not located directly behind the pupil, you must use off-center viewing. Also, in dim light, you might need to move your eyes more slowly to prevent blurring of images than during the day.
Scan slowly to permit off-center viewing
Concentrate directly on each object for a few seconds
Look only at far away, dim lights
The most effective method of night scanning is to use off center vision, which means looking to the side of an object, and to scan slowly to prevent blurring.
look to the side of the object and scan slowly
scan the visual field very rapidly
look to the side of the object and scan rapidly
As with the previous questions scanning should be done slowly in small sectors using off-center (peripheral) vision.
a series of short, regularly spaced eye movements to search each 30-degree sector
regularly spaced concentration on the 3-, 9-, and 12-o 'clock positions
peripheral vision by scanning small sectors and utilizing off-center viewing
The steady red light is a position light on the left wing and the flashing red light is an anti-collision beacon. If you are looking at the left wingtip, the other aircraft would be crossing to the left.
The other aircraft is approaching head-on
The other aircraft is crossing to the right
The other aircraft is crossing to the left
The white position light is on the tail and the flashing red light is the anti-collision light. Therefore, you would be looking at the rear of the aircraft, which indicates it is flying away from you.
The other aircraft is flying away from you
In this case, you are seeing both wingtip lights. If there was no white tail light in between them, you would most likely be looking head-on at the aircraft.
You should try to make night VFR approaches the same as day approaches.
at a higher airspeed
the same as during daytime
with a steeper descent
The key word in this question is "large" accumulations. This condition can produce a loss of muscle power.
an increased sense of well-being
tightness across the forehead

Hypoxia occurs when the body tissues do not receive enough oxygen.
A condition of gas bubble formation around the joints or muscles
A State of oxygen deficiency in the body
An abnormal increase in the volume of air breathed
Hyperventilation occurs when the breathing rate is too rapid or too deep. It usually occurs with stress and can occur with or without the use of supplemental oxygen. Aerosinusitis is an inflammation of the sinuses and aerotitis is an inflammation of the m
Emotional tension, anxiety, and fear can cause the rapid, deep breathing associated with hyperventilation.
The excessive consumption of alcohol
Emotional tension, anxiety, or fear
An extremely slow rate of breathing and insufficient oxygen
Slowing the breathing rate is one of the best ways to stop hyperventilation. Breathing into a bag and talking aloud are also helpful.
increasing the breathing rate in order to increase lung ventilation
slowing the breathing rate, breathing into a paper bag, or talking aloud
breathing spontaneously and deeply or gaining mental control of the situation
Since carbon monoxide poisoning is a form of hypoxia, its effects are increased with altitude, where there is less oxygen available.
air pressure increases
The rods in the human eye can take up to 30 minutes to fully adapt to the dark. Bright lights must be avoided for this amount of time.
Avoid red lights at least 30 minutes before the flight
Wear sunglasses after sunset until ready for flight
Avoid bright white lights at least 30 minutes before the flight
To avoid spatial disorientation, a pilot must rely on the instruments in the cockpit and not the feelings from the sensory organs.
having faith in the instruments rather than taking a chance on the sensory organs
leaning the body in the opposite direction of the motion of the aircraft
shifting the eyes quickly between the exterior visual field and the instrument panel
