10.36.2. Describe the symptoms, effects and immediate treatments for the following hazards present in the aviation environment: 

Carbon monoxide 

Symptoms

  • Headache
  • Nausea
  • Shortness of breath
  • Cherry purple lips and fingernails

Effects
Carbon monoxide molecule binds with haemoglobin preventing carriage of oxygen to the tissues
Thus causes hypoxia

Treatment
Removal of the source of the gas and get immediate medical attention 

Fuel

Harmful to skin
Can possibly be absorbed into the bloodstream 
Lubricating oils

Harmful to skin
Can possibly be absorbed into the bloodstream 

Hydraulic fluids

Harmful to the skin
Can be absorbed into the bloodstream

Treatment would be to remove the substance from the skin exposure and get medical help urgently 

State the recommended time period between the donation of blood and flying.

State the recommended time period between the donation of blood and flying.

24 hours is the minimum time from donation blood and flying, provided only 1 unit of blood is donated 

If more blood or if the pilot is not feeling well after donation, more time must be given between donation and flying. 

Describe the effect on the body of donating blood.

Describe the effect on the body of donating blood.

Loss of circulatory blood volume resulting in potentially low blood pressure which can cause fainting and low hemoglobin

May reduce tolerance to hypoxia and G forces and energy levels generally

Explain why illegal/recreational drugs are unacceptable for pilots.

Explain why illegal/recreational drugs are unacceptable for pilots.

They can affect mood and behaviour and mental functioning

They can cause permanent brain damage

The effects last long after the drug has left the body

State where information can be obtained about the suitability of over the counter and prescription medication for flying.

State where information can be obtained about the suitability of over the counter and prescription medication for flying. 

Medicines affect each person differently. You must not take advice from anyone other than an approved aviation doctor when it comes to flying and medication. 

An aviation approved GP doctor can give information on what medication can be used / taken whilst flying

Explain the effects of drugs on pilot performance.

Explain the effects of drugs on pilot performance.

All non-prescribed drugs are not acceptable for pilots.

Effects can last longer than the drug in the system

Heavy drugs and so called “party drugs” are seriously dangerous and cause degraded performance, addiction, and death.

Cannabis has been linked to heavier addictions and degraded performance

Stay-awake formulas are also not acceptable
for pilots

Absolutely prohibited in pilots

State the recommended time periods between the consumption of alcohol and flying.

State the recommended time periods between the consumption of alcohol and flying. 

It takes time for the body to remove alcohol.

As a general rule, a pilot must not fly for at least 8 – 12 hours after drinking small quantities of alcohol.

After heavy drinking, alcohol may still be in the blood 24 hours later.

Sleep will not speed up the removal process and may cause the elimination of alcohol to take longer due to slowing the body’s processes down.

Explain the effects of alcohol on pilot performance.

Explain the effects of alcohol on pilot performance.

Alcohol is a depressant. It depresses the body’s natural defenses (sensitivities, cautions and fears) while at the same time, lowering capabilities.

Even small quantities of alcohol in the blood impair one’s performance and judgement, with the added danger of suppressing anxiety and removing inhibitions.

An alcohol influenced person can perform poorly, believe he is performing marvellously and may not be deterred by danger.

The effects of alcohol are aggravated by high altitude, where there is less oxygen

Describe the following factors, including their effects on pilot performance and methods by which they may be minimised/managed:

Describe the following factors, including their effects on pilot performance and methods by which they may be minimised/managed: 

Arterial disease

Coronary artery disease and Brain artery disease.

If the pilot has risk factors for coronary artery disease they must take positive steps to reduce these.  If cardiac surgery eg bypass / stenting, procedures are deemed successful then they may be reassessed to be medically fit to return to flying.

Blood pressure

High blood pressure is a risk factor for coronary artery disease.  The best way to reduce high blood pressure is changing your lifestyle – healthy diet, weight loss, avoiding alcohol, regular exercise.  This will also help your general health, fitness and well-being.  If medications are required they are need to be approved by your Doctor, but the side effects have to be minimal.

Low blood pressure increases the risk of fainting / dizziness. 

Diet

Going on a ‘diet’ is not recommended for pilots as it can upset normal body function and potentially lead to hypoglycemia (low blood sugar).  The term ‘diet’ implies a short term strategy when what is required is a long term change in lifestyle and eating habits.

Exercise

Most common forms of exercise are recommended for general health and fitness.  Watch out for contact sports where injuries can be a preclusion to flying.  Effective protection should be worn when playing potentially dangerous sports associated with loss of consciousness or eye injury (boxing, squash) 

Obesity 

Generally doesn’t sit right with a pilot who is trying to maintain “general good health” and can lead to later health problems. There can be problems getting in and out of the cockpit and may cause obstruction to free and full movement of controls.

Smoking

Not compatible with someone who is trying to maintain a high level of health and fitness, causes greater susceptibility to hypoxia and can lead to health problems later in life.

Respiratory tract infection/allergies 
(including colds, sinus, hay fever, influenza, asthma)

These conditions can affect the pilots clarity of thinking and decisive reactions will be less.  A blockage of the Eustachian tubes can cause pain due to pressure changes and loss of the ability to equalise, in the worst case lead to the rupture of the eardrum and dizziness also associated with this.  If a cold is mild and the pilot can equalise the ears easily – then they may be allowed to fly. 

Food poisoning and gastroenteritis 

Not good if a toilet is needed frequently. Can be associated with pain, dehydration and reduced energy levels.  There is a tendency to reduce food intake which is also not good.  

Neurological factors 
(including fits/epilepsy, brain injury, fainting, headaches, migraines)

Anyone who can become incapacitated in the cockpit is not allowed to fly.

Emotional factors (including depression and anxiety)

High stress levels generally negatively affect performance.  A chronic or current mental illness is not compatible with flying.  A past brief mental illness such as a reactive depression may result in an assessment and fitness to fly so long as a full recovery has been made. 

Describe the problems associated with pregnancy and flying.

Describe the problems associated with pregnancy and flying.

Problems can arise if there are any of the following complications of the pregnancy:

Anemia, nausea, tiredness, low blood pressure

In later pregnancy there are issues with getting in and out of the aircraft, reaching and moving controls and harnesses.

Flying is not recommended after the 26th week of pregnancy (6.5 months)
