Aeromedical Question

[BRIGADEAVIATOR]

Hey everyone,

Well i'm working on my CFI right now and I'm having some trouble finding this both on the internet and my many books. In the PTS i'm supposed to find:

"Relationship between a pilots physical condition and vision"​

I dont know if i'm looking too hard or its something simple like a cold can affect vision etc... but if anyone can point me in the right direction maybe in the far/aim or maybe i should just call an AME?? I'd greatly appreciate any pointers

Thanks,
Raul​

Maybe hypoxia?

maybe


night vision deteriorating around 5000 at night

it would be hypoxia

Hypoxia is also what affects the night vision at +5000ft.


Quoting out of "Basic Flight Physiology" 2nd Ed. by Richard O. Reinhart, M.D., it says on pg 108 under the title "Factors Affecting Visual Acuity" the following:

"In either day or night flight, there are factors, many controllable, that can seriously affect the efficiency of vision. This impairment is more noticeable during night-vision flying. The most important is hypoxia. Since the retina is an actual anatomical extension of the brain, anything that affects the brain immediately affects vision. Lack of oxygen first affects brain tissue; thus, vision is concurrently eroded by reduction of sensitivity of rod cells. Low light conditions add to this erosion."

That was the first paragraph. It has about another 1/2 page of text under said subject (factors affecting visual acuity). I will not type that off, but it mentions carbon monoxide, fatigue, and alcohol. But if you have some brain you can figure out what those 3 do to you - relate to hypoxia
