Lufthansa A350 muss in Luanda zwischenlanden! AeroNews
A350 has to make an unplanned stopover on its way from Cape Town to Munich suddenly the passengers find themselves in the middle of Africa, more precisely in
Luanda in Angola there logically no one arrived and therefore there is a little bit of anger and misunderstanding on the internet though we only gave a handful of details about this airport its once again a great example to show how decisions are made in the cockpit and i really hope you can answer some questions have fun and with that hello and a warm welcome. I hope you are good.
The flight we are talking about today is actually a completely normal
Lufthansa flight from Cape Town, one of the most popular long-haul travel destinations in Germany today, to Munich. It is done daily with the Airbus
A350. Normal flight time is just under 11 hours a day pure flight the machine on this X-ray Eco has been in use for just over 5 years re old R350 900 already the outbound flight of this machine overnight was delayed around 11:30 am. m. local time in Cape Town a little over two hours late the plane then returned home 286 passengers were on board as was the almost full
A350 after take off heading south there was a long right hand bend at a altitude which, when the weather is good, allows a wonderful view of the city and Table Mountain, among other things, and then we continued north for a good 30 minutes after takeoff it was then only 37,000 feet a little below 38,000 feet and therefore the cruising altitude for the next few hours reached three hours and 20 minutes after takeoff in the airspace of Angola, the Airbus left these 38,000 feet again, which is about 11,600 meters and not 10 minutes after the Aircraft appears on the radar screen of air traffic control with the squwk seven seven there we have to d It is only important for me to say that of course we do not know all the details and all the information that was available to the cabin crew at this point in the book and it's also very important that I'm not trying to make any statement. here on behalf of
Lufthansa about this particular flight
Lufthansa does that itself and I don't know more about this than the rest of the internet.
I'm just trying to explain all these aviation specific things in an understandable way and for you. With this information we can collect about this flight via Flightradar for example to show what might have happened there so Squalk 7700 that means we pilots got a transponder code from air traffic control then we can select this four digit code. code consisting of numbers between 0 and 7 in the cockpit and the very simple explanation is that an aircraft is primary radar as a Recognized Object in the airspace, this primary target is provided with this code with the help of the secondary one on the ground, which looks up the transponder code on the aircraft, and so the dot on the radar screen can be identified as, say,
Lufthansa five seven, which actually breaks down very simply these days, such a secondary combination with a transponder on the plane side is good for a lot of other things and can also provide a lot more information than just helping to identify the plane but I think and that's fundamentally understandable Well because this code is selected by the cabin crew of course , you can somehow communicate with air traffic control with the help of this transponder and this code and booths and it's interesting for us because we can see part of the communication between air traffic control and the cabin through the flight passengers because they can read this transponder code, so to speak, without having to listen to the radio there are three international emergency codes of particular interest are 75 Zero Zero for the hijacking of a Seven Sixx Zero aircraft for a radio failure and Seven Seven Zero for a general air emergency one of these codes is set sets a number of things that happen in Seven Seven Zero Zero has the aircraft in an air emergency Priority above all other machines and is fully supported by air traffic control the aircraft can also move more or less freely in the airspace air traffic control then clears the way for the aircraft to communicate over the air but of course also quite simply with the words mayday mayday mayday passing on this river g according to flight radar at 1 p.m. m. at least then transponder code 7 zero zero was set which is 2 p.m. m.
German time a good three and a half hours after take off in Cape Town and this message is definitely not given lightly the
A350 had a problem with one of the engines and In order to understand this a bit better let's dig into the logic a bit of the Airbus system. The plane cannot always immediately adjust all the irregularities with one engine. The plane itself notices the vast majority of serious errors in particular, but this reliably covers the ikam is the centralized electronic monitoring of aircraft and knows different levels of errors Levels 2 and 3 are particularly interesting here, the so-called amber corsion , i.e. an error message marked in yellow requires the attention of the cabin crew causation and any action related to the engine related error, this can be, for example, the error message Engine oil temperature high one The actions to be taken are given in front of a level 3 message, however a red warning requires immediate intervention by the cabin crew and here there are also handles in front of engine fire one, for example, there is such a warning and it is precisely this warning that the crew received, as is apparent from current reports and the airport statement, the specific handles Falls by the first of all have the objective of extinguishing the fire turning off the engine and thus securing it at high altitudes inevitably means that you have to give up the travel altitude because the performance of the still available material plant is no longer sufficient to maintain the altitude and at the same time the flight speed, so that a further flight to Munich is already possible at this point already immediately excluded in the w In the further course, even the ECAM then notifies ATC and at this point the emergency call follows at the latest in case of such an error and the transponder code seven seven zero is set, as we have just discussed this error, which now inevitably results in the failure of an engine, is actually always an emergency, even if the fire has extinguished, because it's a massive loss of redundancy and there are very few situations where it would actually make sense, not on this Mayday call to go with a four-engine plane in r The reality may look a little different maybe you remember there was a point with a cut off on the lufthanse 747 that had to return to New York after an engine failure which is not necessarily an emergency a really burning engine so an engine that it's still burning the fire alarm is still there after sticking two fire extinguishers in there which ensure any plane is a time critical emergency no matter how many engines the plane has it also has these colors and different levels of errors often associated with a country as soon as possible, so with a terrestrial sun it is possible in amber or in red, of course, another meaning that they should help the crew in their subsequent decision-making yellow or red is not always automatically synonymous with time and critical or critical time, but you can and should, of course, help the crew with this time and when you have done these limitations and found out if it is an e critical or non-critical time error, then it goes to the so-called foredeck, that is, to the decision-making model that we use in the cockpit the letters represent facts options risk and benefits is Decision execution and control of said foredeck are adjusted accordingly depending on whether the weather is critical or non-critical and this mainly affects the risk of points and the benefits Essential important points that should always appear are for example the equipment of a possible alternate airport, that is say, how old is the runway is there an instrument landing system and the weather there is good other points of interest are, for example, if the airline has some kind of maintenance staff stationed there is usually a station some kind of own staff for handle passengers with many and good hotels can make passengers travel well from this balance airport and what are the rules of e input, etc.?
In the event of an engine fire in the interest of everyone on site, we can shorten the duration of the crew on this flight from Cape Town to Munich who now had to deal with a critical timing error near
Luanda in the center of Africa which doesn't have too many big alternate airports They looked for the first proper solution as they learned it and as it is correct and decided obviously to lose there and from this critical number thankfully everything became one we could say upon successful completion of the fire warning because we don't know at all if there really was a fire truck by successfully processing everything at a time of non-critical abnormality, which in turn gave the crew the opportunity to fly over louander airport in about 30 minutes of holding patterns to burn some fuel to save the weight of the plane to reduce and such the plane then landed safely in
Luanda seen from l at a distance with these few details that we have for this flight a completely correct and fully understandable decision operationally everything is of course a huge challenge on such a long journey, but how could it be otherwise Allowing 300 people to enter
Luanda without planning it, then distributing them to any hotel and then organizing the trip as quickly as possible is a great effort despite the fact that
Luanda with Frankfurt three times a week non-stop and x-raco is the Affected.
The Art 350 will probably be around for a while because obviously something was really wrong with the engine and that will mean a lot of maintenance work, maybe even mean the engine needs to be replaced, we don't know all of that yet and that will change later in the next In days but people don't come home with this plane anymore so it's a story no one really enjoys but it can happen and from an aeronautical point of view with the little data we have available what was done there it is quite clear, safe and understandable. decision and maybe also a good example to remember which countries and which places you really fly when you take a relaxed gondola to Cape Town in ten hours.
In this sense, that is what it should be today. Thank you very much for watching I hope there was some interesting information for you there were really interesting articles about this flight so I hope I was able to answer some questions at least regarding the flight part and I hope to see you very soon a new video until then that have a good time and goodbye we can do it for a moment do the crew on this flight from munich at the point we can do the short flight
