Kann ein normales Privatflugzeug rückwärts fliegen wenn es stärkeren Gegenwind hat als es fliegen kann?

Loading...Hallo, gibt es eine Lizenz für das Führen eines Kampfjets, z.B. wie ATPL für Pasagier Flugzeuge? Hab im Internet dazu nichts gefunden
Da ich fliege muss ich wissen wie viel “Wh” 2cr5 Batterien haben. Ich fliege mit Wizz Air. Was darf ins Handgepäck? Danke im voraus 😁
Sind Fallwinde gefährlich und stellen eine gefahr dar? Wie entstehen diese und wie häufig sind diese?
Hallo zusammen, ich habe einen Flug nach Paris gebucht. Ich fliege von München nach Paris. Allerdings ist mein griechischer Reisepass abgelaufen und mir liegt kein anderes Ausweisdokument vor. Kann ich trotzdem fliegen, wenn mein neuer Reisepass noch nicht vorliegt? Wird man in Paris nochmal kontrolliert? Bitte nur ernste Antworten. vielen Dank!
So ein komisches Ding auf dem Flügel
This can in principle be any aircraft, regardless of whether it is a private aircraft, a commercial aircraft, a military aircraft or whatever it is for an aircraft.
When the wind comes from the front and the wind speed is higher than the speed at which the aircraft moves through the surrounding air, then it moves relative to the ground not forward but backward.
I have also experienced when I was to transfer a Piper J3C from France to Austria. The Mistral in Rhonetal came from the front and a forward was not possible. In the climbing flight I actually flew backwards!
Yeah, I remember that from my time at the Air Force. There we had a Dornier Do-27 as a connecting plane in the squadron and that was the case.
One could see how it was pushed backwards with very strong wind (which was no problem at the North Sea) and, despite full performance, did not come from the spot. She had to turn around and try something different.
I don’t know if there’s a modern plane flying “backward”. Maybe someone knows a pattern here (motorized, not a sailplane).
Do 27 at the Bundeswehr? That was not a private plane, but a military plane. The questioner asked explicitly whether this can be a private aircraft 🙂
Hi, thanks for the info, but I don’t understand the meaning of the comment. I interpret the question even more in the direction of “small aircraft”, i.e. according to today’s definition “SEP/L up to 2,000 kg departure mass”.
So, what is the difference whether a Do-27 is used privately or militaryly? It was not designed for armed operations, it was used as a connecting aircraft and it was also in civil execution.
And a Do-27 with civilian painting has not acted differently than the military version. Prof. Grzimek, the animal researcher, had a Do-27 in Africa and that was civilian (at least had a zebra painting). So there were at least one machine that was not used militaryly.
But if you can prove that only the military version could fly “backward”, I am grateful for a hint. Then I can update my database.
Yeah, I know. But if you’re working in traffic aviation, you think “big.” And I think it’s a good working hypothesis to assume that at least 80% of all viewers/listeners equal small planes with “hobby flying”.
And probably 80% of these machines are also used for recreational aviation in associations or for training purposes at flight schools or are owned by “residence pilots”.
I don’t want to discriminate against the little planes. They also have a right of existence under the great, wide, infinite heaven.
You missed an important emoticon. This was at the end of the commentary.
I am always wondering that single-engined aircraft up to 2 to MTOW are either called private aircraft or sports aircraft.
I used to operate such aircraft professionally, but neither were the private aircraft (they belonged to a legal person) nor were they used for sports purposes.
Yes, it is possible, but only with a few aircraft that have a very low minimum speed. So-called STOL(Shoard Take-Off and Land(on German short start and landing). And most of the civilian variants are only delivered to the civilian sector military aircraft. Like the Fiesler Storch(Wehrmacht(Declaration/Botplane), later mainly to air rescues on a limited area) or the Pipr L-4 both aircraft can stand on the spot with enough counterwind and fly, start and land back. If you still ask, just say it
it would have to go, it is exactly the same situation as if a boat with 10km/h drives a flow upwards, but it runs down at 15km/h?
To the water it drives forward, to the landscape it drives backwards.
Yes / No.
It then moves forward relative to the air medium, i.e. produces quite normal lift.
It can move backwards relative to the ground.
Please take into account the earth rotation if it would fly to the west or east.
Sure. Earth curvature must also be taken into account, which is why in long-haul flights the machine must always trim slightly head-loaded 🙂
Irrelevant (if that was not a fun comment from you). Any deviations occur due to the Coriolis force, are negligibly low and occur even with “normal” forward flight.
It does not move forward to the air medium if the counterwind is stronger than the propulsion by propeller or engine. Then it can’t fly anymore.
I’m gonna have to chew on it…
Actually, it should not matter to the propeller whether the air moves backwards faster relative to the ground than the propeller can generate propulsion…
At least good objection!
yes! assumed it flies to the air with 100km/h, the wind blows but with 110km/h against the aircraft it would fly back to the ground with 10km/h.
Thank you. The most helpful answer I’ve been waiting for.
What kind of pilot did you ask? A hobby pilot with 100 flight hours?
In principle, it can be no matter how fast the air mass travels in which it flies. This has nothing to do with a crash flight and the dynamic pressure does not increase as long as the True air speed does not change.
Just to understand: Imagine a plane flying over a closed cloud cover and surrounding a hot air or gas balloon.
Neither the pilot of the aircraft nor the pilot of the balloon notice whether a wind blows or if there is still wind.
So everything is harmless. Would the cloud cover now dissolve and both the pilot of the aircraft and the pilot of the balloon would now realize that the balloon is actually blown over the surface of the earth at high speed all the time, what would change?
Nothing! As long as the air mass flows laminar, it doesn’t matter how fast this air mass moves.
I know! got so many in the air that the plane would crash!
Thank you!
So, once asked a pilot:
Flight on the spot or reverse flight with strong wind is quite possible and not even so unusual. The flight position remains stable as long as the surfaces are uniformly surrounded by air.
He couldn’t tell me whether this is the case with any high counterwinds. This is as similar to a crash flight, at some point the dynamic pressure at the front edges of the wing becomes unhealthy. The propulsion of the propeller, however, ensures that the aircraft always moves forward in behavior to the air masses, no matter how high the counterwind is.
I’m afraid you didn’t understand my objection…
So there’s nothing else I said.
Of course, it is important, in the end, that the propellers are so much producible that the buoyancy force is produced if this is the case at a speed of, for example, 100 km/h to the air, it would also lift who is flying backwards when the wind is 150 km/h.
then it will not start
No, because then no buoyancy is produced on the supporting surfaces. The “lift” is generated by the pressure difference of the air flowing past the upper and lower sides of the support surfaces.
Of course, buoyancy is generated when the wind flows quickly enough over the supporting surfaces. If the difference of the speed of the air and that of the aircraft is greater than the lifting speed, the aircraft can start and fly backwards with all controls, etc.
Perhaps we have different views about the reference framework here: my thought approach is based on “airspeed”, not on “groundspeed”…
no, it is slowed down
Define flying? With enough wind, cars can fly.
Otherwise, things are naturally built to fly forward 😐
Of course you do. http://www.youtube.com/watch?v=YeKpLFuXusc
No, because it would crash immediately, as there would be a flow break.
The flow is caused by the counterwind. The plane doesn’t matter, which causes the buoyancy.
