Why is oxygen so important?
Already at heights from about 10,000 feet (approx. 3,048 metres) can cause the Oxygen saturation in the blood fall below 90 %. In older people or people with health problems, this value can be reached even earlier. This drop in oxygen saturation has a direct effect on brain performance, which can lead to fatigue, confusion, inability to make decisions and, in extreme cases, even unconsciousness. These symptoms are signs of Hypoxiaa condition in which the body does not get enough oxygen to maintain vital functions.
A Pulse oximetera small device that measures the oxygen content in your blood can provide valuable services here. It gives you precise information about the current state of your body and helps you to make informed decisions about whether you should carry extra oxygen on your flight. Some pilots only consider it necessary to carry oxygen at altitudes above 12,000 feet (approx. 3,658 metres), but oxygen support can already be useful at lower altitudes, for example to Headache or to arrive at your destination relaxed and rested.
Hypoxia: dangers and prevention
Hypoxia is one of the greatest dangers of flying at high altitude, and its symptoms can appear gradually. The EASA brochure on the subject of hypoxia emphasises how important it is to recognise the risks on flights over high altitudes at an early stage and to take appropriate measures. Symptoms such as Dizziness, drowsiness, shortness of breath or a general feeling of confusion should not be ignored.
A "Plan B" in case such symptoms occur is essential for every pilot. But if you look around Swiss aerodromes, you realise that only a few aircraft are equipped with Oxygen systems are equipped. This is surprising, because the Aviation rules according to Part-NCO (NCO.OP.190 and NCO.IDE.A.155) explicitly authorise the carrying and use of portable oxygen systems. In fact, these systems are readily available, easy to operate and can be used in aircraft without any problems.
There are no technical or legal obstacles that prohibit carrying oxygen on an Alpine flight. Portable oxygen systems are not only permitted, but should be actively considered when flying at high altitudes. After all, the risk of hypoxia is real and the effects on flight safety are serious. In view of the fact that oxygen saturation can drop to critical levels below 10,000 feet, it is worth considering the use of a portable oxygen system or at least giving it a try.
Portable oxygen systems: a sensible investment?
Have you ever thought about taking or renting a portable oxygen system on your next alpine flight? These systems are now compact, user-friendly and relatively inexpensive. The extra oxygen can not only help you to cope better with the physical and mental demands during the flight, but also help to ensure that you are more comfortable after landing. Relaxed and without discomfort get off the aeroplane.
The discussion about the use of oxygen in general aviation, especially for flights at high altitudes, is becoming increasingly important. Organisations such as the AOPA (Aircraft Owners and Pilots Association) are increasingly recommending the use of oxygen systems, even for flights below 12,000 feet, to ensure the well-being and safety of pilots.
Conclusion: Oxygen is not a luxury - it's safety
The use of supplemental oxygen when flying at high altitudes, such as when crossing the Alps, is not just a precautionary measure, but an active contribution to your own safety and performance. Every pilot should take the possibility of preventing hypoxia and flying with a clear head seriously. With a simple Pulse oximeter you can ensure that your body gets enough oxygen to cope with the challenges of flying at high altitudes.
The question remains: How well do you know your own body? Are you sure that you will be able to fly at high altitudes without oxygen? It is worth actively tackling the issue of oxygen supply - not just when you notice the first symptoms of hypoxia.
If you would like to find out more, there are numerous sources that will give you a deeper insight into the topic. The AOPA has published an extensive report entitled "Pilots Need (More) Oxygen", which goes into detail about the need for oxygen when flying at high altitudes. The German Medical Journal offers valuable insights into the health aspects of hypoxia and oxygen deficiency during a flight with "Hypoxia in an aircraft - physiological considerations in flight".
Overall, the use of oxygen when flying at high altitudes is not a question of luxury, but a question of Safety and performance.
