Question 141-11 : How many stages of sleep are there including rem sleep ?

5 stages.

There are five phases of sleep usually when you are sleeping you begin at stage 1 and go through each stage until reaching rem sleep and then you begin the cycle againeach complete sleep cycle takes from 90 to 110 minutes your brain acts differently in each stage of sleep in some of the stages your body may make movements but in others your arms and legs will be immobilestage 1 sleep is light sleep you experience a drifting in and out of sleep you can be easily woken up your eye movement and body movements slow down you may experience sudden jerky movement of your legs or other muscles these are known as hypnic myoclonia or myoclonic jerksstage 2 around 50 percent of your time sleeping is spent in stage 2 sleep during this stage eye movement stops and your brain waves a measure of the activity level of the brain become slowerstage 3 is the first stage of deep sleep the brain waves are a combination of slow waves known as delta waves combined with faster waves during stage 3 sleep it can be very difficult to wake someone up if you are woken up during this stage you may feel groggy and disoriented for several minutesstage 4 sleep is the second stage of deep sleep in this stage the brain is making the slow delta waves almost exclusively in this stage it is also very difficult to wake someone up both stages of deep sleep are important for feeling refreshed in the morning if these stages are too short sleep will not feel satisfyingstage 5 rem rapid eye movement sleep is the sleep stage in which dreaming occurs when you enter into rem sleep your breathing becomes fast irregular and shallow your eyes will move rapidly and your muscles become immobile heart rate and blood pressure increase men may develop erections about 20 percent of sleep is rem sleep for adults

Question 141-12 : The main purpose of lumbar support is to ?

Produce an even pressure of the discs by allowing the lower spine to curve naturally.

Question 141-13 : How is yellow fever contracted ?

A virus transmitted by an infected mosquito.

Question 141-14 : Otic barotrauma is worse during the descent than climb because ?

The air in the middle ear is at a lower pressure than the cabin this closes the eustation tube so that the pressure cannot be equalised.

Question 141-15 : Flying with a 'common cold' ?

May lead to incapacitation due to severe sinus or ear pain.

Question 141-16 : Hearing tests are carried out during pilot medicals to ?

Detect early signs of deafness.

Question 141-17 : Noise induced hearing loss nihl ?

Is a condition resulting in permanent hearing loss of selected frequencies.

Question 141-18 : Presbyopia ?

Is common over the age of 50.

Question 141-19 : Colour blindness ?

May be subtle and only detected using specialised tests.

Color blindness color vision deficiency is the inability or decreased ability to see color or perceive color differences under normal lighting conditions it does not affects acuity there is no known treatment for colour blindness

Question 141-20 : Concerning the light sensitive cells of the eye ?

The cones detect colour vision and are highly sensitive to hypoxia.

The cones detect colour vision and the fovea therefore gives us great resolution colour vision at normal every day light levels for things we are looking directly at of all the body organs the brain and the eyes are most sensitive to hypoxia

Question 141-21 : Pilots should not fly immediately following giving a donation of blood ?

Because there is a small increased risk of low blood pressure due to loss of blood volume.

The danger is the risk of fainting and the cause of that is the low blood pressure see aic 972004 blood plasma and bone marrow donation flying and air traffic control1 many aircrew and controllers have expressed the wish to donate blood in support of the national blood transfusion service blood donation is invariably a safe painless and uneventful procedure and the blood volume is restored within a few hours by redistribution of body fluids and intake of soft drinks and beverages a few individuals feel faint afterwards but this effect is minimised by resting supine for a short time 15 20 minutes 2 blood and plasma donation21 aircrew211 aircrew are advised that in order to prevent the very slight risk of post transfusion faintness or syncope they should refrain from donating blood or plasma if they are required to fly within twenty four hours22 air traffic controllers221 air traffic controllers are advised to avoid donating blood if they are going on operational duties within a minimum of twelve hours they can however give blood when coming off shift3 bone marrow donation31 after bone marrow donation which involves a general anaesthetic the minimum interval recommended before duty for both aircrew and controllers is forty eight hours however the individual response to this procedure varies and specialist medical opinion should thus be sought

Question 141-22 : Which of the following statements is true concerning regular physical exercise 1 it increases pulse rate and stroke volume in the short term2 it reduces blood pressure and heart rate in the long term3 it increases the human tolerance to hypoxia ?

1 2 3.

Exercise increases the body's demand for oxygen but regular physical exercise increases the human tolerance to hypoxia

Question 141-23 : Heart attack myocardial infarction ?

Is a total blockage of a coronary artery leading to the death of a piece of heart muscle.

Question 141-27 : During a rapid decompression in a two crew aircraft the other pilot becomes incapacitated your first action is to ?

Don your own oxygen mask.

Yetoli so that there is a risk of 2 incapacitated don your own oxygen mask = put your own oxygen maskin case of a rapid decompression don your own oxygen mask first as a first and immediate step when the cabin altitude warning occurs

Question 141-28 : The percentage of oxygen in cabin air ?

Is the same as at sea level.

The percentage of oxygen in cabin air remains unchanged 21% at all flight altitudes but as altitude increases the partial pressure of oxygen decreases

Question 141-29 : Which counter measure can a pilot can use against a barotrauma of the middle ear ?

Stop descending climb again and then descend with reduced sink rate.

Question 141-30 : The approximate time required for complete adaptation of the eye when moving from darkness to light is ?

10 seconds.

Question 141-31 : Is it possible to suffer from aerodontalgia in the descent ?

No.

Aerodontalgia is a pain in the teeth that results from a change in air pressure if air is trapped in diseased or badly filled teeth it expands during the climbthe pain will go when the aircraft descends

1 3 and 4 only.

Question 141-35 : What is the maximum jaaeasa bloodalcohol limit for flight and cabin crew ?

20 milligrams per 100 millilitres of blood.
