Also having trouble finding out whether smoking and physiological altitude statements mean, a smoker or someone smoking at the time. Eg At sea level a 5 percent saturation of COHb in the blood gives a physiological altitude of about 8000 ft.
Now this 5 percent saturation of COHb in the blood, is that someone smoking at that time or just some one who does smoke, but is'nt at present.
Think the first.
But they quote a pilot who smokes is at 5000 ft then physiologically is at 10000 ft. But this is only if he is smoking at 5000 ft right.
Thanks
