Ovi su imali srece. Levi wingman je sve vreme nestabilan (i pre pocetka akrobacije).

Skoro sam siguran da ovo nije prvi low pass Wizaa u Budimpesti. Postoji gomila fotki na forumima, ipak je Wizz delom njihova firma a preleteti Parlament je izuzetna reklama.

Naravno da nije ovo jedini Wizzov let, bilo ga je i ranijih godina. Sada to rade sa A321 koji je nov u njihovoj floti.

Airbus lansira letelicu bez motora do ruba svemira

Evropski proizvodjač aviona Airbus lansiraće danas u stratosferu svemirsku vazduhoplovnu jedrilicu "Perlan 2" iz američke savezne države Nevade, a jedan od kopilota biće i izvršni direktor Airbus grupe Tom Enders.



Jedrilica će poleteti večeras oko 21 čas po srednjoevropskom vremenu, a let će trajati izmedđu 30 minuta i dva sata, uz mogućnost 24-časovnog odlaganja u slučaju kiše, koju su najavili meteorolozi.

Cilj programa je pokazivanje da je moguće preživeti u uslovima sličnim onima na Marsu.

Airbus i misija "Perlan 2" nameravaju da testiraju sistem bezmotorne aeromreže pri različitim brzinama i različitoj visini, nivou opterećenja i vibracija.

Cilj je takođe da se utvrdi da li je jedrilica dovoljno jaka da izdrži ekstremne uslove koji bi mogli da dovedu do njenog uništenja, kao i mogućnost da pilot preživi let bez unošenja dodatnog vazduha spolja, rekao je agenciji Frans pres vođa projekta Ajnar Enevoldson.

Misija "Perlan 2" je projekat vazduhoplovne jedrilice koji su zajednički razvili inženjeri i astronauti, a Airbus je učestvovao u finansiranju projekta s četiri miliona dolara.

Airbus Perlan Mission II Glider Soars into History
09/24/2015 | Airbus Group
http://www.aviationworldnews.com/news/a ... tory-40084

The Perlan 2 glider, the world’s first engineless aircraft designed to reach the edge of space, achieved its successful first flight today in a historic moment about 5,000 feet above Roberts Field, the Redmond Municipal Airport in Oregon.

This was the first test flight of the aircraft, which next year will attempt to set a new world altitude record for any airplane. The goal of this project is to open up a world of new discoveries related to high-altitude flight, climate change and space exploration.

“Airbus Perlan Mission II is a historic endeavour in the truest spirit of aviation’s earliest pioneers,” said Tom Enders, Chief Executive Officer (CEO) of Airbus Group. “The knowledge gained from this project will impact how the world understands and addresses climate change. But it will also help Airbus continue to innovate ways to fly higher, faster and cleaner, on Earth and possibly beyond.”

The Perlan 2 glider was developed by The Perlan Project, a volunteer-run, non-profit endeavour headed by leaders in aerospace and engineering. It is supported by Airbus Group and a group of other sponsors that includes Weather Extreme Ltd., United Technologies and
BRS Aerospace.

We’re extremely excited about the successful first flight of the Perlan 2 glider,”said Ed Warnock, CEO of the Perlan Project. “This marks a major breakthrough in aviation innovation, one that will allow winged exploration of the atmosphere at the edge of space and lead to new discoveries to unravel some of the continuing mysteries of weather, climate change and ozone depletion.”

Jim Payne and Morgan Sandercock piloted today’s flight, which was the first of many for the Airbus Perlan Mission II team as it prepares to soar the aircraft to the edge of space in Argentina in 2016. The Perlan 2 is a pressurized sailplane designed to ride air currents that, in certain mountainous regions near the north and south poles, can reach into the stratosphere. Next year’s flights are expected to reach 90,000 feet, exceeding even the altitudes achieved by the U-2 and the SR-71.

Despite having no engine, the glider’s true flight speed at that altitude will be more than 400 mph and the air density will be less than two percent of what it is at sea level. The crew will breathe pure oxygen provided by a rebreather system, similar to what astronauts use in space.

In addition to its two-person crew, the aircraft carries scientific instruments to provide new insight into climate change and our upper atmosphere. Because it lacks an engine, Perlan 2 can explore the edge of space without polluting the atmosphere it will study, opening up human knowledge on several fronts :

- Understanding Weather – What happens at the highest levels of the stratosphere impacts weather around the globe, and Perlan 2 will be able to directly observe important atmospheric phenomena that previously have only been speculated about.

- Predicting Climate Change – Perlan 2 will collect and share data with atmospheric scientists worldwide, to improve climate models and more accurately predict climate change.

- Diagnosing the Ozone Layer – Perlan 2 can take untainted air samples from the stratosphere to measure the levels of ozone-damaging chemicals and assess whether the ozone layer is replenishing or still depleting.

- Future of Aviation – Many of the high-altitude weather phenomena Perlan 2 will encounter have implications for aircraft performance and safety, especially as commercial aviation strives to operate aircraft at higher altitudes.

- Future of Space Travel – Perlan 2 will operate in atmospheric conditions roughly similar to those on Mars, providing insight into how wingborne aircraft could operate above the Martian surface.

Izvestaj komisije o udesu Fly Dubai u Rostov na Donu:

The second approach was flown manually in flight director mode (like the first approach), at 220 meters/720 feet of height and 4.5km/2.42nm before the runway threshold the crew decided to go around, one of the likely reasons being an air speed increase of 20 knots to 176 knots within 3 seconds. The engines were accelerated to 101/102% N1, maximum takeoff/go-around thrust. During the go around the crew retracted the landing gear and reduced the flaps to 15 degrees.

Climbing through 1900 feet AGL at nose up attitude of 18 degrees the pilot flying pushed the control column forward resulting in a nose down movement and reduction of vertical acceleration to +0.5G and an increase in airspeed causing the automatic retraction of flaps from 15 to 10 degrees at a speed of above 200 KIAS.

The engine thrust was reduced for a brief period resulting in a speed decrease, the flaps returned to 15 degrees, then engine thrust was increased again to TOGA, the flaps retracted automatically again to 10 degrees, the flaps remained in that position until impact.

The pilot flying applied nose up inputs resulting in a vertical climb rate of 16 meters/s (3150 fpm).

At a height of 900 meters/2950 feet a simultaneous nose down control input and a stabilizer nose down deflection from -2.5 degrees (6.5 units) to +2.5 degrees (1.5 units) occurred resulting in the aircraft, after having reached 1000 meters/3300 feet, to begin to descend and experience a vertical acceleration of -1.0G.

According to FDR the nose down trim input came from the stabilizer trim switch at the control column and lasted for 12 seconds while the cockpit voice recorder recorded specific noise of the trim wheels rotating.

The MAK wrote: "The following crew recovery actions did not allow to avoid an impact with the ground". The aircraft impacted the runway about 120 meters past the runway threshold with a speed of more than 600kph/324 knots and more than 50 degrees pitch nose down killing all occupants and destroying the aircraft.

Totalni sam laik za upravljanje avionom , ali bih hteo nešto da pitam:

Pilot je trimovao "volan", tako da u neutralnom položaju kormilo visine bude otklonjeno 2.5 stepena prema dole (dakle, kao da je za toliko gurnuo volan od sebe). Kako je to samo po sebi izazvalo nesreću, tj. zašto je uopšte bitno? Zar ne bi pilot trebalo da gleda instrumente i vidi da je nos usmeren ispod horizonta? I kao reakciju na to, da povuče volan prema sebi, bez obzira kako je trimovan?

Da li trimovanje komandi utiče na auto-pilot (po meni, ne bi trebalo)? Nisam shvatio kako je došao od 2.5 do 50 stepeni i zakucavanja u zemlju?

„FOD Walk“ prvi put na aerodromu „Nikola Tesla“
Na aerodromu „Nikola Tesla“ prvi put je organizovan Foreign Objects Debris Walk (FOD Walk).
Šetnja u cilju ručnog uklanjanja eventualnih neželjenih objekata i krhotina sa poletno-sletne staze trajala je dva sata, od 14 do 16 časova. Poletno-sletnu stazu dužine 3.400 metara peške je prešlo 46 ljudi zaposlenih na Aerodromu, saopštila je beogradska vazdušna luka

– Prema pravilima, aerodromske službe redovno kontrolišu piste i ostale delove površina po kojima se kreću avioni, a FOD Walk akcije sprovode se na aerodromima širom sveta, u cilju dodatnog isticanja značaja bezbednosti vazdušnog saobraćaja. Ova akcija na beogradskom aerodromu održana je prvi put, sa nadom da će postati tradicionalna – saopštio je aerodrom „Nikola Tesla“.

Kakva je Flybe kompanija, među ovim low cost, kako se kotira? Znam da ne lete iz BG već iz ZG. Ako bi leteo za UK razmatram to kao opciju, da mi je možda isplativije čak i sa troškom puta do ZG. Išli bi porodično, dakle 4 karte.
