Human Factor questions.

[Mohit_C]

Hi,

I have a few questions which I came across in the Volare Question Bank and I think they are wrong. These are the questions:

Q 543)
Which statement is correct?
1. Smokers have a greater chance of suffering from
coronary heart disease
2. Smoking tobacco will raise the individuals
pysiological altitude
during flight
3. Smokers have a greater chance of decreasing lung
cancer
A) 1,2 and 3 are correct (according to the mark scheme)
B) 1 and 2 are correct, 3 is false (what I think)
C) 1 and 3 are correct, 2 is false
D) 2 and 3 are correct, 1 is false

Q479)
At what altitude ("threshold for compensatory
reactions") does the human organism start with
remarkable measures to compensate for the drop in pO2
when climbing?
At about:
A) 6000-7000 FT (according to the mark scheme)
B) 8000-9000 FT
C) 9000-10000 FT
D) 10000-12000 FT (what I think)

Q510)
The normal rate of breathing is
A) 32 to 40 cycles a minute
B) 60 to 100 cycles a minute
C) 20 to 30 cycles a minute (according to the mark scheme)
D) 12 to 16 cycles a minute (what I think)

Q493)
To safely supply the crew with oxygen, at which altitude
is it necessary to breathe 100% oxygen plus pressure
after a rapid decompression ?
A) Approximately 14 000 ft.
B) Approximately 20 000 ft.
C) Approximately 45 000 ft. (what I think)
D) Approximately 38 000 ft. (according to the mark scheme)

Q16)
Healthy people are usually capable to compensate for a
lack of oxygen up to
A) 20.000 feet
B) 25.000 feet
C) 10.000 - 12.000 feet (according to the mark scheme)
D) 15.000 feet (what I think)

Could someone tell me if the mark scheme is wrong for these questions or if not explain where I got mistaken.

Thanks.

Regarding q543, the 2go.aero question bank (q630) agrees with you and so i'm sure would most of the medical world.

Thanks. I have added another question to my doubts.

[BHenderson]

They say that night vision is affected above 6000ft if that helps you to remember question #479.

#510 I would agree with 20-30 per minute. Breathing is normally quite shallow. My average is about 3 seconds per breath. Which gives 20 per minute. 12 per minute is a bit long, as this gives 5 seconds per cycle.

#493 I learnt 40,000ft. So 38,000ft is safer than 45,000ft.

#16 I become seriously hypoxic at about 13,500ft and I consider myself normal. I can feel it starting at 11,000ft. I agree with 10-12,000ft as per the mark scheme. I believe the law in the UK prohibits flight above 10,000ft without oxygen if this helps you to remember it.

q510 = q104 on the 2go aero question bank, answer 16 cycles per min.

[ChrisLKKB]

q479 = q351, 6-7000 ft

It seems like my Human Factor book just differs from the information of this question bank. Anyways, thanks for the replies guys!

Just wait until you get to the pyschobabble section...

Q. Your mother prefers 2 sugars in her tea, whilst your father once scored 254 in tenpin bowling. From this you can deduce that:

a) It will rain tomorrow
b) Your future children might be allergic to cats
c) Red cars are faster than blue cars
d) The light in the fridge does not stay on when you close the door

And if you think that's a right load of bollocks, wait until you do the exam!

A question like this for instance:

Q481)
During the cruising phase of a short-haul flight the
captain starts to smoke a cigarette in the cockpit. The
flying copilot asks him to stop smoking because he is a
non-smoker. The captain tells him: 'This is your
problem', and continues smoking. What should the
copilot do?
A) He should report the chief pilot about this behaviour of the
captain
B) He should not further discuss this issue but should come
back to this conflict during the debriefing
C) He should learn to accept the captain smoking cigarettes in
the cockpit
D) He should repeat his worries about smoking in the cockpit
and should argue with the captain about this problem until
the conflict is solved

The ideal answer is B.

The reality... the OM Part A will have the company's smoking policy. The captain would know what that policy states and therefore, would know if he/she's in breach of it.
