Und außerdem, die meisten Probleme lösen sich immer unerwartet schnell in Luft auf

Vor Allem, wenn da eine andere begehrenswerte junge Dame am Horizont auftaucht...... und man sich dann fragt, was man an der Vorigen denn soo toll fand....

Alles Gute zum Geburtstag!

Logisch. Jeder macht mal so ne Phase durch, wo man leidet wie ein Hund....... :streichel:

Sagen wir mal so, ohne daß es herablassend klingt oder besserwisserisch:

Jeder Rückschlag ist ne Vorbereitung auf das nächste Mal, so daß man es zu schätzen weiss und geniessen kann.......

Wer kennt das nicht??

Der neue Learjet von Bombardier im Plan für Indienststellung im Jahr 2013
12.07.2012, 00:28:00
Das Flugzeugprogramm Learjet 85 macht unverändert Fortschritte in Richtung auf die ersten Flüge mit vier Testflugzeugen in unterschiedlichen Bauphasen. Der erste komplette Rumpf mit Druckkabine einschließlich Bug- und Heckrumpf, wird derzeit einer finalen Validierung unterzogen, bevor er von Querétaro (Mexiko) nach Wichita (Kansas) gebracht wird.

Die Arbeiten an der Innenkonstruktion der Tragflächen für den ersten Learjet 85 wurden in Querétaro abgeschlossen. Sie befinden sich jetzt in der Endmontageposition für die Installation der Tragflächenbeplankung. Der Zusammenbau einer zweiten Tragfläche, der Teil der statischen Konstruktionstests ist, ist auf gutem Wege.

"Je weiter wir auf der Entwicklungs-Roadmap vorankommen, sind die Teams in unseren Learjet-Werken und an den Produktionsstandorten ehrlich froh, dass wir uns zielstrebig dem Jungfernflug des Learjet 85 nähern", sagte Ralph Acs, Vice President und General Manager für den Learjet bei Bombardier Business Aircraft. "Unsere Zulieferer halten sich weiterhin an unsere strikte Planung für die Zusammenarbeit mit unseren strategischen Partnern in allen unseren Flugzeugprogrammen. Die Endmontagelinie in Wichita steht bereit und wir sehen der Montage des ersten Flugzeugs mit Spannung entgegen.

.........

Der Typ Learjet 85 wurde am 30. Oktober 2007 als grundlegend neue Konstruktion auf Kundenwunsch aufgelegt. Er ist der größte, schnellste und leistungsfähigste Learjet, den es je gegeben hat.

Als würdiger Nachfolger einer legendären Tradition ist der Learjet 85 dazu bestimmt, die Erwartungen der Learjet-Halter an außerordentliche Leistungsfähigkeit, überragende Technik und außergewöhnliche Wertschöpfung zu erfüllen. Das Düsenflugzeug wird von zwei Triebwerken vom Typ Pratt & Whitney Canada PW307B angetrieben, von denen jedes 27,13 kN Startschub auf Meereshöhe bei bis zu 30 °C bei geringer Lärmentwicklung bringt und der fortschrittliche NOx-emissionsarme Brenner geringere Umweltauswirkungen aufweist. Zielwerte dieses Typs sind eine max. Reisegeschwindigkeit von Mach 0,82 und eine transkontinentale Reichweite von bis zu 5.556 km (i).

Das Cockpit des Learjet 85 vereint fortschrittliche Technik mit überlegenen Designmerkmalen und bildet ein vollkommen neues Cockpitumfeld. Die neuesten technischen Entwicklungen und überlegene Designästhetik des Vision Flight Decks von Bombardier werden übertragen, um das ultimative Flugkontrollumfeld in diesem Jearjet-Typ zu schaffen.

Das Kabinenmanagementsystem dieses Flugzeugs wurde von Lufthansa Technik entwickelt und enthält ein Hochleistungs-Ethernet-Netzwerk, einen digitalen Verstärker für die Versorgung der Hi-Fi-Lautsprecheranlage und eine Schnittstelle zur Unterstützung des Klimamanagements in der Kabine sowie der Beleuchtungs- und Temperatursteuerung. Die offene Architektur des Systems ermöglicht die problemlose Integration von externen Systemen und neuen Applikationen, z. B. HD-Funktionen.

New Cockpit

Not all the changes in the cockpit are as apparent as the new avionics. The cockpit was redesigned with smooth lines all over and extra storage space, although that will no longer be needed for bulky paper charts. Bombardier designed the cursor-control device (CCD), which uses a trackball for cursor movement, and added leather to the yoke and brushed-aluminum trim on the flap, slat and parking-brake levers. Designers tried the brushed aluminum on the CCD, but switched to a rubbery material to help pilots maintain a grip on the device.

According to Bombardier, the new cockpit is all about vision, and this is embodied in the Rockwell Collins Head-Up Guidance HUD, which delivers the first certified display of synthetic vision on the HUD. This capability is made possible by the HUD’s use of LCD projection, which allows replication of the detailed graphics needed for synthetic vision system (SVS) rendering. The SVS on the HUD is monochrome, using the same green as the normal HUD images, while on the PFD SVS is rendered in full color.

More avionics manufacturers are putting HUD symbology on the PFD, and the Vision cockpit faithfully replicates the HUD flight path vector (FPV) and other elements on the PFD. This is helpful because the FPV shows exactly where the aircraft is going–say, into those towering cumulus clouds visible through the HUD or, using the SVS on the PFD, into that red mountaintop up ahead. Both the PFD and HUD use the same input from the inertial reference system, and they are thus well matched. The harmonious replication of HUD symbology on the PFD is also an aid to the pilot because there is much more of a natural transition when moving between the HUD view and looking down at the PFD. The standard Vision cockpit comes with one HUD on the left side, but dual HUDs are an option.

Interestingly, there’s one element of the HUD that isn’t replicated on the PFD: when the airplane nears a destination airport, that airport is identified on the SVS view in the HUD by a white dome, which grows increasingly translucent the closer the airplane gets to the airport. This makes spotting the airport quick and easy. The dome symbol, however, isn’t used on the PFD because it was felt this might cause too much clutter. I find that the dome is a great tool, although it could usefully become less translucent closer to the airport.

The other key part of the Vision cockpit for the Globals is the enhanced vision system (EVS), fed by a new Esterline CMC CMA-2700 SureSight EVS infrared camera with five times better resolution than the previous system and a new algorithm that improves the image contrast. Alas, I could not see the EVS in action because it was awaiting final certification. Once it is certified, pilots will be able to view the EVS image both on the instrument panel displays and on the HUD. The image isn’t fused or combined with SVS (that will probably come in the future), but the pilot will be able to switch among the normal HUD, SVS and EVS view through the HUD using a button on the yoke.

Bombardier is waiting for software upgrades that will remove a flight-manual restriction against using EVS. The EVS system will also be usable for operators to obtain credit to fly 100 feet below decision height during instrument approaches, per FAR 91.175. “The EVS is functional,” said Yann Lemasson, Bombardier chief pilot, flight operations; “it’s just the approval that has not been granted yet to use it.”

Weather and Radar

The Rockwell Collins Multi-Scan weather radar fills in what pilots normally can’t see–a view of the rain embedded inside clouds. But Multi-Scan also uses the terrain database combined with multiple views of different slices of the sky to eliminate ground clutter automatically. And if the airplane is turning to get around a cell, Multi-Scan remembers the forward view and keeps that cell displayed in the correct relative position to the side, even if the radar antenna can’t see the cell anymore. This Global 6000 also includes XM weather capability.

Full Fans 1/A and CPDLC capability is built into the Vision cockpit and FMS, but operators will have to get a letter of authorization to use that feature.

The new Globals come with an Apple iPad for each pilot. The Vision cockpit includes two L-3 electronic flight bags, which Lemasson said they mostly use for cabin control functions, as a backup to the galley control panel and individual seat controls. Charts can be displayed on the Vision displays as well as on the iPads. Lemasson said that his crew doesn’t install charts onto the EFBs, although that could be done. Charts on the Vision display are approved to show own-ship position both during approaches and on airport surface charts. The iPads include Bombardier’s new document management app, which stores and maintains all the manuals needed for that specific airplane. Pilots can pull up manuals on the Vision displays as well, another reason not to have to carry paper on board.

A new feature, not yet implemented, will allow pilots to build a flight plan away from the airplane then plug it into the FMS using a USB flash drive.

Training

Lemasson said that it took him and his colleagues four sessions in the simulator to get used to the Vision cockpit. The official training to upgrade to the Global Vision cockpit takes four days, including two days of ground school and four simulator sessions, but the system is intuitive enough that it shouldn’t take most pilots much time to become comfortable. Conventions such as cursor clicking on a waypoint to bring up a menu of options are becoming common in modern business jet cockpits anyway, so that won’t be new for many pilots.

Pilots making the transition from the Primus 2000-equipped Global to the Vision cockpit can replicate some of the old look and feel by splitting the screens on the Vision displays into a Primus-like layout. Lemasson’s preferred setup is to use the screens in front of the pilots as full landscape PFDs, with navigation on the center display and system synoptics on the lower center display.

Each display can be split, so the copilot’s PFD, for example, could show the ADI on the right (with or without SVS) and an approach chart on the left, but all on the same display. Pilots can change these views at any time, but Lemasson prefers to use the system’s memory keys, which allow up to eight different layout choices to be stored and quickly recalled. He keeps a list of the memory keys’ content in the airplane’s standard operating procedures.

The Global 6000 has autothrottles and automatic fuel balance and transfer to optimize cg for best cruise efficiency. This is done by a preprogrammed fuel-burn sequence, which starts consuming fuel from the main wing tanks, then from the center tank, then back to the main tanks, the aft fuselage tank then finishing with the mains. The sequence optimizes the load at the 33-percent cg line.

“One thing that’s really cool on this aircraft is in the information management,” Lemasson said. “This is what really struck me. What they are giving me is a lot of possibilities yet they don’t clutter my displays. If you have too much information in front of you, you get distracted. You can add or remove what you want. In some cases it’s auto-declutter–it knows if you have too much stuff. If you have too many airports selected, if you zoom in, it declutters. At school they teach you one way [to do things]. We sat in the airplane and discovered two or three ways. Rockwell Collins did a fantastic job.”

SVS Credit

Lemasson also appreciates the SVS on the HUD, and is looking forward to eventual approval of lower minimums using SVS. “On an approach in Puerto Rico,” he said, “we were in cloud and I could see everything. And I had to move my head sideways [away from] the HUD to see I’m still IMC. You see the mountains, the rivers, the towers, the buildings, you see the runway; it’s all there. So if you have 200 feet ILS Category I minimums or a Waas LPV approach and you cannot land the aircraft, it’s because it’s really, really bad.

“You almost have to think, no, the runway’s beyond that fog layer or that cloud, but I see it, and I’m ready to call minimums, or I call the runway, and no I don’t. We tested it in the sim, to minimums–200 and a half–and the visual representation in the HUD, the situational awareness is such that you can’t legally go down but it’s all there. The credit is what would make it official.”

The next step for the Vision cockpit is gaining approval for lower minimums credit using SVS. Last year, the RTCA released DO-315B performance standards for using SVS for lower minimums on an ILS to 150 feet. “We flight tested a HUD SVS prototype system on our Challenger with the regulatory authorities earlier this year,” said a Rockwell Collins spokesman. “As is the case for any new navigational system, the FAA requires a formal proof-of-concept study. We are engaging the FAA in a [POC study] to examine the new technologies and operational concepts. Following the study, as well as certifying the actual hardware/software, the FAA will stipulate the operational requirements for going to lower minimums. For example, special conditions for the operation (for example, special authorization CAT I), crew training and qualifications and so on.”

Flying the Vision

I flew the Global 6000 from the left seat, with Bombardier demo pilot Bruce Duggan in the right seat and Lemasson in the jump seat. There isn’t much new with the automatic starting of the Fadec-controlled, 14,750-pound thrust Rolls-Royce Deutschland BR710A2-20 engines.

Duggan did our weight-and-balance calculations on the Vision display, which shows a chart that makes it easy to adjust the load to keep the cg within the envelope. The results can be printed on a cockpit printer behind the captain’s seat.

When using the CCD, there is only one place on the display that the cursor can’t go, and that is in the window that shows Eicas (engine indication and crew alert system) messages. Each pilot has his own cursor; the captain’s is cross-shaped and the copilot’s X-shaped. If one pilot needs to move the cursor to a window occupied by the other pilot’s cursor, he can bump out the other pilot’s cursor. The graphical interface using the cursor is just one way to make changes; there are FMS buttons as well as quick-access keys programmed for common operations. But for pilots who have grown up using computers, positioning the cursor over a waypoint, then clicking and bringing up the menu of options for that waypoint will be a familiar move.

We took off from Runway 33 at Bradley International Airport near Hartford, Conn., where the Bombardier demo team is based. Our fuel load was about 15,000 pounds and takeoff weight about 68,000 pounds, well below the 99,500-pound mtow.

Steering the big Global on the ground is easy with the tiller, although nosewheel steering is quite sensitive, as are the brakes. The mainwheels are 42 feet behind the cockpit, and Duggan recommended waiting to turn until the yellow centerline on the taxiway was adjacent to our shoulders.

The Global 6000’s autothrottles take over and advance the thrust once the levers are pushed through about two-thirds travel. Duggan called V1 then Vr and it took just gentle back pressure to lift the nose off the ground. I wanted to practice flying with the HUD, so I followed the guidance cue, what Duggan called the “donut,” and kept it inside the FPV during the departure as we climbed to 28,000 feet.

We flew almost one hour, from Bradley to near Plattsburgh, N.Y., then back to Bradley for the ILS 6 approach. As we climbed and returned, we tried the graphical interface on the Vision displays, viewed XM weather and traffic and compared the monochrome SVS on the HUD to the colorful SVS on the PFD.

I hand flew the ILS approach to see how the HUD worked in the Vision cockpit. As expected, the dome over Bradley Airport came into view on the HUD SVS as we descended; this is a great aid to situational awareness. We had the ILS 6 approach plate displayed on the right side of the center MFD; the left side showed engine gauges and system synoptics. And as a backup for situational awareness, the approach plate showed our own-ship position, our airplane rendered as a little purple jet crawling from the upper right corner of the chart toward the ILS approach.

A high broken cloud layer demonstrated the benefit of having SVS on the HUD; we could “see” the ground through the clouds using the HUD, while viewing the clouds and not having to look down at the PFD and back up through the windshield. This is a neat capability that becomes comfortable and normal in little time.

Flying the ILS using the HUD produced a smooth and accurate approach. I found it so easy to keep the guidance cue donut inside the FPV that I almost didn’t look at the other data on the HUD such as the airspeed and altitude readouts or the glideslope needle. Of course, Duggan was monitoring everything carefully, but the SVS on the HUD showed me the hills near Bradley Airport and exactly where the runway was and the FPV positioned over the touchdown point. As we neared the runway, the runway on the HUD was clearly outlined. Having flown both a Challenger 601 and the Global 6000 with HUD, I can easily see why pilots used to flying with HUD are called “HUD cripples” because they use the system so much.

Our reference speed on final approach was 116 knots. Duggan said that even though the HUD gives flare guidance starting at 50 feet, he recommends looking beyond the HUD to pick up outside visual cues. I could have stowed the HUD but preferred to keep it in view during the approach and landing.

As we neared the runway, aural cues sang out our altitude, at 50, 30, 20, then 10 feet. The autothrottles retarded thrust to idle at 50 feet, then at 30 feet, as instructed by Duggan, I pitched up slightly to stop our sink rate, and the Global 6000 plopped smoothly onto the runway. The spoilers deployed automatically, then I lifted the finger switches on the thrust levers, the engines went into reverse idle and when the reverser buckets were fully deployed I was able to pull the thrust levers back to full reverse.

Having flown the Vision cockpit for two months before our flight, Duggan appreciates the improvements over both the Rockwell Collins Pro Line 21 and Honeywell Primus 2000 systems. “There are so many different ways to configure the cockpit,” he said. “We can set it up to what we’re used to, which helps us manage the information that’s being presented. It’s in its infancy. The growth potential is whatever you can imagine, because it’s software-related. It’s not like you have to change a bunch of boxes.”
