#1. Flying following giving blood can lead to:
Flying shortly after giving blood can lead to Hypemic Hypoxia and an increased risk of fainting (syncope).
Even if you feel perfectly fine on the ground, your body has a reduced ability to carry oxygen and handle pressure changes for a period after donating.
1. Hypemic Hypoxia
While regular “Hypoxic Hypoxia” is caused by a lack of oxygen in the air, Hypemic Hypoxia happens because you don’t have enough red blood cells (hemoglobin) to carry the oxygen that is available.

#9. Effective lookout is best achieved by:
The best procedure for pilots to look out involves a systematic, focused scanning technique, not just casual glances, using short, 10-degree eye movements to observe distant points for at least one second to allow for focus, covering areas horizontally and vertically, and adjusting for blind spots (like wings) by leaning or maneuvering to maximize visual awareness and detect traffic

#11. Moving aircraft are more difficult to see if they:
Moving aircraft, especially those with little or no relative motion (converging), are harder to see because the human eye is better at spotting movement, but a potential collision target that appears stationary can blend in, creating a significant risk

#13. Rapid breathing and tingling in the finger tips are signs of:
Rapid breathing and tingling in the fingertips are primary signs of Hyperventilation.
In aviation, hyperventilation is especially dangerous because its symptoms are almost identical to Hypoxia (lack of oxygen). This can lead a pilot to make the wrong correction, which could make the situation worse.
Why it Happens
Hyperventilation is often triggered by stress, anxiety, or fear. It occurs when you breathe faster or deeper than the body needs, which “washes out” too much Carbon Dioxide (CO2) from your blood.

#14. The major constituent of the gas content of the atmosphere is:
The major constituent of the atmosphere is Nitrogen, which makes up about 78% of the air.
While we often focus on oxygen for breathing, the atmosphere is actually a mixture dominated by nitrogen.

Technically, the actual percentage of oxygen in the atmosphere stays the same at 21% (specifically 20.9%) all the way up to about 70,000 feet.
However, because the air pressure is much lower at 10,000 feet, the “effective” amount of oxygen is much less.

#20. Following flying in extremely cold conditions, you find your fingers are showing signs of frostbite. You should:
If you suspect frostbite in your fingers, you must act carefully to avoid permanent tissue damage.
-
Use Body Heat: Tuck your fingers into your armpits or have a companion hold them with their warm hands.
-
Warm Water Soak: Submerge the fingers in warm—not hot—water. The ideal temperature is between 37°C and 40°C (about the temperature of a comfortable baby bath).
-
Duration: Keep them in the water for about 30 minutes or until the skin feels soft and sensation returns.
-
Expect Pain: Re-warming is often very painful and can cause a stinging or burning sensation. You can take Ibuprofen or Paracetamol to help with the pain

#23. Maximum weekly intake of alcohol for men and women are:
The NHS recommends that both men and women should not regularly drink more than 14 units of alcohol a week, and it’s best to spread this consumption over three or more days, including alcohol-free days, to keep health risks low.

#24. At what height should a pilot consider the need for additional oxygen?
In the UK, under Civil Aviation Authority (CAA) and EASA regulations, a pilot in an unpressurised aircraft must use supplemental oxygen continuously whenever the cabin altitude exceeds 13,000 feet, and for any period lasting more than 30 minutes when the cabin altitude is above 10,000 feet.

#25. Treatment for irregular blood pressure will preclude a pilot from flying:
No, it does not usually preclude you from flying.
Treatment for high blood pressure (hypertension) is very common among pilots. As long as your blood pressure is well-controlled and the medication you are taking is “approved,” you can usually maintain your medical certificate.

#26. Suffering from Epilepsy would preclude a pilot from flying:
Suffering from epilepsy in the UK doesn’t automatically preclude you from flying, but it’s a serious medical condition the UK CAA closely scrutinizes, often requiring a lengthy seizure-free period (e.g., 10 years without medication for some cases) or demonstrating a very low recurrence risk, especially for private pilots; however, active epilepsy or recent seizures usually lead to unfitness, with strict assessment for commercial flying making it very difficult, often disqualifying due to safety risks.

Symptoms of carbon monoxide poisoning
Carbon monoxide gas is colourless and does not smell, so you cannot tell if it is around you.
Symptoms of carbon monoxide poisoning include:
- a headache
- dizziness
- feeling sick or being sick
- feeling weak
- tiredness and confusion
- chest and muscle pain
- shortness of breath
- your face turning hot and red (flushing) – but redness may be harder to see on brown and black skin
- loss of vision

#36. The lack of Oxygen is known as :
The lack of oxygen reaching the body’s tissues is known as Hypoxia.
In aviation, this is particularly dangerous because it can happen gradually without the pilot noticing.
Common Symptoms

Confusion or poor judgement.
-
Euphoria (feeling “high” or overly happy despite being in danger).
-
Cyanosis (a blue tint to the lips or fingernails).
-
Reduced vision, especially at night.
