Flugzeugabsturz in der Ostsee! AeroNews
it is an absolute horror story, a plane flies normally in the sky at first sight, however, all the people on board are unconscious and therefore inevitably fly to certain death, it is a story that actually happened already in the past and it's a story that could have repeated itself now what does that mean let's take a look and say hello and a warm welcome hope you're doing well most probably you've already noticed somewhere a private zeiss to be more To be precise, a 551 series Intercitation 2, a twin-engine business jet with space for up to 10 passengers, depending on equipment, was en route from Jerrys to Colonia last Sunday, the southern Spanish city with its very manageable airport some 70km from Seville is a popular starting point for holiday trips to and through Andalusia since Jerrys, the machine made its way with the Oskar Eco Foxtrot Golf Romeo license plate is registered in Austria alr around 3 p.m. back home maybe after a week holiday in Spain or something like that and even before this rotation the plane was always grounded for longer periods, for domestic German flights to Bremen or to Hamburg to Sylt on Majorca or once in a while from time to time for a flight to southern Germany to Neuhausen airport simply manageable use with only 23 flights this year, which is relatively typical for an aircraft that is privately used publicly known and became the honorary president of the Cologne Carnival Association of Blaue Funken The businessman and the pilot were confirmed, however, the course of the accident has not yet been confirmed and it will also be quite some time before the investigation is completed and an official report is published.That is Very important, a lot of what we're telling you today is based on speculation, but there's already quite a bit of confirmed evidence that points to what could have happened and let's look at it. or in detail now the business plane left Jerez on runway 20 in a southwesterly direction and then turned 180 degrees to the right in a northeasterly direction and quickly found itself listening over Seville passed the machine already at 25,000 feet, which is about 7,500 m above sea level 30 minutes after takeoff, the aircraft reached the cruising altitude of 36,000 feet, which is about 11 km above sea level, still in Spanish airspace, so within the first hour of flight Air Control Pilot of problems with reported to the pressurized cabin, of course it is documented exactly when this important radio message was sent, we know publicly that unfortunately not at this time, but it will be very relevant to the investigation, but what What we do know is that radio contact with the machine was made a little later, shortly after the departure from the Spanish peninsula was interrupted and could not be reestablished either, which indicates that the occupants of the machine could no longer act about an hour after departure and possibly unconscious in the plane in the atmosphere of what we have all already provided above the air becomes thinner and thinner at sea level this pressure in the standard atmosphere is exactly 1013.25 hectopascals if you climb a mountain for example the 4,807 meter high Mont Blanc highest mountain in the Alps then you measure one The air pressure was only half as high at around 550 hectopascals in this flight, but the cruising altitude was around 11,000 meters, the air pressure there was only around 230 hectopascals, and therefore not even 30 percent of the air pressure at sea level is felt at to breathe. at such high altitudes it's actually still pretty normal because there's still air you can breathe in and out and the percentage composition of the air hasn't changed compared to sea level, it's still 21% oxygen 78% nitrogen and the rest then In addition to that, however, the number of oxygen molecules in a certain volume has changed significantly compared to soil, so there are significantly fewer oxygen molecules and that means that the partial pressure of oxygen has decreased significantly and for us humans this can become a big problem.
Big problem, because the body no longer has the opportunity to supply the blood with sufficient quantities, it ends up being enriched with oxygen and therefore quickly becomes unconscious. The time when you can still function significantly at high altitudes is called the time of useful consciousness. which is then 36,000 feet less than 30 seconds, which means you're at cruising altitude and there's a sudden If there's a drop in cabin pressure, then you have less than 30 seconds to put on your oxygen mask, which then drops from the cabin roof in large commercial aircraft or is always within reach of the pilot in the cockpit nothing changes in the partial pressure of oxygen and therefore also nothing in the fact that the body no longer has the opportunity to enrich the blood with enough oxygen this user awareness time applies to all of us and can, for example, be caused by age or general health through the question of whether you smoke or not it is not yet known The oxygen mask, which you then immediately put on, increases the cabin pressure, yes, but not again, however, it changes the percentage composition of the air you breathe, because now through the mask of oxygen you breathe almost 100% oxygen, which means that the composition changes and the partial pressure of oxygen increases significantly and thus the lungs have the opportunity to enrich the blood with enough oxygen again and you remain conscious.
Now there are many exciting experiments in this pressure that you can do in the ground. where you can do something like that and I'll link you to my Youtube video on this which is also shown over and over again in pilot training one person stands in front of the other and tells him if he doesn't put this on. oxygen mask now then you'll die and the person whose usage time will be aware has already been massively exceeded just smiles back and doesn't know anything else what's going on and that's where all of this can get really scary a commercial airliner that's pressurized it also has an appropriate warning system that alerts the cabin crew that something is wrong with the cabin pressurized the pressure in the cabin is too low and therefore the pressure level in the cabin is too high as soon as this warning appears we have two very important tasks in the cabin first of all we put on the oxygen mask no buts that will be done anyway and then we start a so-called emergency penny to sink as fast as possible to a height where you can breathe normally again, even without an oxygen mask, we are still talking here about a sudden drop in pressure, there is a loud bang, then the whole cabin fogs up, it suddenly gets very cold and everyone knows exactly what is going on, but it could also be that there is a slow drop in pressure The pressure in the cabin is not building up quite correctly due to the technical problem or it is it escapes slowly and gradually through a very small hole at cruising altitude and the big problem with such a slow pressure drop is that it's not so easy to identify and not so easy to recognize maybe all three passengers got the nice feeling of slowly getting tired and want to fall asleep in this relaxed afternoon even quite ignorant of what is going on maybe the pilot who is allowed to drive this business jet only has the seitation 2 in this version it is an aircraft approved for single pilot operation Maybe because the right decisions weren't made fast enough, maybe because the aircraft technology didn't work as it should, at some point it's expected that e These details will become clear in the future, but it is clear in French airspace.
If the business jet can no longer be contacted by radio, an attempt is made to establish contact with the machine on all frequencies. The jets' task is then to find the aircraft, identify it, and then fly so close to the machine that they can look into the cockpit. But maybe it was also because the cabin windows were fogged up or the cabin was so fogged up due to the pressure drop. Unfortunately, we do not yet know at this time the details that we hope will appear in an official report at some point but could act on board Time probably never And moreover, the machine's autopilot simply flies the previously entered route, in this case to Cologne , it is quite normal that the complete flight path is already entered before takeoff, for example this curve is comparatively steep because near Paris at the Tussi place it is standard in this type of flight paths from this direction in most cases you get a shorthand here so you don't have to fly this point in the first place but of course the plane just did it since it was stored on board computer once the route is finished the autopilot exits a navigation mode where this flight path reverts to a basic mode and then just holds the last heading flown and that's exactly what probably happened here shortly before from Colonia at the last point of the flight path on a heading, the journey continues for so long until the fuel runs out that it's pretty good math, maybe it was with the Jerez airport clarified how much the plane had refueled because when you order fuel for a flight you order a total amount of fuel and maybe later you could find out this total amount of fuel in the default airport communication, but you still have to have enough fuel for the way to an alternative airport and a reserve on board within 30 minutes, so it was possible to calculate that the fuel will not run out on land but in the Baltic Sea, the German Eurofighters then delivered the Danish F16s and could observe how around 40 German time the fuel it's really over.
This spiral that then arises, which can be observed, for example, on the flight radar, is caused by the fact that, of course, an engine fails on one side, the flight altitude and speed can no longer be determined. hold, the autopilot jumps out at some point and the aircraft probably at some point n goes to the ground even with two engines failed, today this is considered the most likely scenario, which actually happened with a business conversation in the past but it also happened a few years ago with a commercial plane, a lot of mistakes were made in the end it just remains an ugly story that will show us once again that flying is not 100 percent safe and we can all learn something new somewhere and optimize still more all here in this regard, that should be all for today thank you very much for looking, hopefully soon there will be more details about this accident and then we can talk about it again if necessary until then have a good time no and bye
