@Goatsilla Jup, ist derzeit ein bisserl ungünstig. Bin ganz froh dass ich letzten Sommer einen gekauft habe, war schon damals mit €5,2k nicht ganz günstig. Heute wäre es deutlich mehr.

@Ruediger_Krause @derniederbayer2 Ist aber aus Charlottenburg eben deutlich jenseits der 30km Marke. Und jeden Tag muss man checken was denn heute gerade fährt oder eben nicht. Da ist man dann schnell bei 3 bis 4 mal umsteigen und mehr als 90 Minuten pro Richtung.

Im Radio interviewen sie eine „Superpendlerin“ (O-ton), die jeden Tag über 200 km pendelt und sich das nicht mehr leisten kann. Ich frag mich, warum Leute sich sowas dauerhaft antun…

@scottiebateman Manuals for both airbus and boeing say the same in this regard: fly the nose wheel promptly and soft to the ground, don’t use aerodynamic breaking as it has all kinds of downsides. No matter what surface is on the runway. Compacted snow, concrete, asphalt, doesn’t matter.

Yet another video appearing today, that gets recycled again, and again. Lots of comments about a “cool landing”… but is it ? Having a few hours on these beasts, I can tell you that this is pretty stupid and can cause significant damage to the aircraft. Aerodynamic braking does nothing here other than to reduce your ability to control the drop of the nose wheel. Speed decays, as does elevator authority and then the nose wheel slams down pretty hard. Possibly causing damage. Totally avoidable if the correct technique is used. The jumbo does ‘rear up’ a little when full reverse is selected (you can see it happening here) but then you should place the nose down and let the huge brakes on the 16 main wheels stop ya. It stops pretty short without any of these theatrics. Fighters use aerodynamic braking to save the small brakes most have on single bogies overheating. Taking the energy out of the high speed landing. The 747 doesn’t need any of that. #avgeek #aviation #boeing747

@MCCCANM There’s a difference between reactive windshear-warning (doesn’t need radar) and predictive windshear warning which requires a Doppler radar. And obviously envelope protection helps, although nowadays autopilots fly the better escape path anyway.

My friend is referring to the crash of Delta flight 191 while on approach to runway 17L at DFW in 1985. Pilots kinda sorta knew about storms & microbursts, to include windshear, but it wasn’t taken so seriously. Flight 191 proceeded into a storm that had perched itself over the approach to the runway, following a LearJet that had landed safely before them. Flight 191 ran into heavy rain, which isn’t much of a problem, but then encountered a microburst & windshear. Airplanes need wind over the wings to fly. Then they fly at a precise speed on approach to avoid “stalling” (losing lift), but slow enough to land & get rid of all the lift after you do, stopping before running out of runway. If you’re flying into a headwind of 15 knots, and the wind suddenly stops, you’ve just lost 15 knots of speed & the lift associated with it. This happened to flight 191, but much, much worse. The pilots had noticed some speed fluctuations, and talked about it, making adjustments to the throttles to make up for the wind. They were keeping themselves on the “glideslope” to the runway…descending ideally at a rate of around 600 to 800 feet per minute, depending on your speed. Around 700’ above the ground, though, it wasn’t enough. They got caught in a microburst. In a microburst, it’s kind of like all the rain & all the cold air the Thunderstorm was holding onto just come dumping downward, all at once. In the same way a thermal will lift the airplane up, a microburst will push it down. You’re already slow for landing & there isn’t much extra lift for the wings to give if you raise the nose. So, at around 700’ above the ground (I’m not sure of the exact height) flight 191 went from holding the Glideslope at 600-800 fpm with maybe 1-2° of nose down attitude, to falling at 3,000 fpm with the nose pitched 30° up to try & arrest the descent. They had pushed the throttles up, then pushed them up to the maximum, but it wasn’t enough. The L-1011 “Tristar” jet touched down in a farmers field short of the runway. The landing gear held up, and the plane rolled along. It crossed state Highway 114 (the road my friend is referring to in his post), hitting a car & a couple streetlights. Fire began to enter the breached cabin; some passengers unbuckled their seatbelts to try and escape & were sucked out. The jet collided with a couple of water tanks & came to rest, torn asunder. 136 of the 163 were killed, as well as the driver of the car. The FAA took action. It ordered that all new commercial jets had to be equipped with “Doppler” radars, which can detect shifting winds & windshear. The jet then announces some variation of “WINDSHEAR, WINDSHEAR” when the Doppler detects it. If it’s present, that’s it…you go around. If it detects it on the takeoff roll, it’s one of the few things we’ll abort the takeoff for once past 100 knots. If we’re too fast to abort, we’ll push the throttles up & delay lifting off the ground until we can’t, building extra speed. Airports also got Doppler radars so ATC could spot the threat, too. Educating pilots about the threat became a top priority. The investigation revealed training was lacking in how to spot & escape from windshear. Now, every jet has some variation of a “Windshear Escape Maneuver”. It’s basically to go to maximum thrust, stow the speed brakes (which aren’t likely to be out) and pitch up to a known, steep angle. If that’s not enough to arrest the descent, you can increase the pitch until you are in & out of the “stick shaker”, meaning you are right above the stall margin. You leave the flaps wherever they currently are - changing flap settings might change lift, but it also changes drag & so it’s kind of an unknown as to what that will do here. You also leave the landing gear wherever it is, to include down…if you’re going to hit the ground, you may as well let them absorb some of the energy. There was one other microburst crash, in 1994. That’s the last one in commercial aviation.

🇳🇱🇪🇺 King Willem-Alexander of the Netherlands has piloted a KLM Boeing 737 for the last time. No one knew he had been doing it for 30 years, in anonymity: the king, in fact, had co-piloted commercial flights for KLM, going by another name, Meneer van Buren. His colleagues knew, but always maintained the utmost discretion about what happened in the cockpit. ✈️

Das ist der Strom, über den immer alle schimpfen, weil er mittags zuviel da ist und "abgeregelt oder verklappt" werden muss. Das muss er dann nicht mehr. Der Speicherbetreiber kauft ihn (häufig für 0 €) speichert ihn einige Stunden und verkauft ihn ab 19:00 für 12-15 ct/kWh.

Über 108 kWh im Akku, das ist für so ein "kleines" Auto schon enorm viel, die Reichweite wird WEIT über allem sein, was man in einem Stück fahren sollte. Und bei 400 kW Ladeleistung geht sich dann nicht mal ein Espresso und Pipi aus. 1000 km in unter 8 Stunden schätze ich mal. Wem das immer noch nicht genug ist, der verlangt wahrscheinlich auch bei der TV-Fernbedienung nicht 6m Reichweite, sondern 600m :-) BTW: Und ich finde das neue Design schon recht cool...

@lucaberta @MCCCANM It is just a normal flight within the Lisboa FIR, so we keep the squawk, it is not an oceanic route. Santa Maria FIR starts outside of that area. Same as the northern Canaria’s FIR is not oceanic, whereas the part south of the islands is.

Your “Squawk” is the 4-digit code you put into the transponder to identify your flight. ATC issues a new, unique squawk for each flight. Sometimes you have to change it in flight when two jets get the same code. The transponder sends data to the radar when the radar “interrogates” the transponder, so ATC knows your altitude & other information. It’s not just a pure radar display ATC is working with…they can do that, but it’s not as reliable. The technology was first developed during WWII as part of the “Identification Friend or Foe” (IFF) program, which allowed us to tell good guys from bad guys on the radar. They called the system a “Parrot” and when it sends signals, it was “squawking”. If they want you to turn it off, the phrase was “strangle the parrot”. (This was obviously a highly classified system, so transponders had a self-destruct switch. Pilots frequently accidentally destroyed the transponder when mistaking the destruct switch for the power switch, resulting in a small but audible thump from a contained explosion, informing you that you had some explaining to do) Anyway, there are several modern ways to go about getting this data to ATC. We now have ADS-B, which gives ATC an even better picture of the airspace…but that’s not the same as squawking. The squawk codes can have various meanings. For example, squawking 1200 means you are flying under Visual Flight Rules (VFR) and not under ATC control (or even talking to them on the radio). 7700 means you have an emergency. 7600 means you have lost your radios. 7500 suggests a hijack has taken place. Other functions of the transponder now allow much more data to be fed to ATC, but pilots sometimes get in trouble for putting little messages in there that they shouldn’t. I’ll leave that to your imagination. Ok, as always, I’m simplifying things here & it’s much more complex, but hopefully you have a decent idea of what squawking is now. Hope it helps!

Squawk 760…1? For about a year now (and unknown to most) Europe has added another code to its family of emergency squawks. We explain how and when to use 7601 in our latest blog: flightradar24.com/blog/aviation-…
