I didn't knew that they will use it in the future in civilian AC's I was
thinking that it is for military only but here a story from a Newspaper.

Sorry it is in German

Nicht ohne Stolz weisen Luxair-Piloten in diesen Tagen auf
eine Pionierarbeit bei der Eurojet-Flotte hin. Als erste
Fluggesellschaft der Welt setzt die luxemburgische Airline auf ihren
Kurz- und Mittelstreckenjets vom Typ Embraer ERJ-145 ein
Flughilfegerät ein, das sogenannte "Head Up Guidance System".
Diese Technik gibt es zwar schon seit vielen Jahren, kam bisher
jedoch fast ausschließlich in Militärflugzeugen zum Einsatz.

Die neue Ausrüstung
unterstützt den Piloten
bei schlechten
Sichtverhältnissen wie
Nebel oder starkem
Regen sowie bei der
Landung auf Flughäfen
mit schwierigem
Anflugverfahren. Das
"Head Up Guidance
System" ist zudem
Voraussetzung dafür,
dass die ERJ-145 der
Luxair für den
Instrumentenanflug
nach strengeren
Bedingungen
zugelassen werden
konnten.

Für Eurojet-Passagiere
kann der Einsatz des
HGS bedeuten, dass
sie sicherer und
pünktlicher ans Ziel kommen - selbst wenn sie es gar nicht
bemerken. Denn ob eine Maschine bei widrigen Wetterbedingungen
planmäßig landet oder startet, entscheidet sich nicht zuletzt aufgrund
eines streng geregelten Zusammenspiels zwischen der technischen
Ausrüstung von Flugzeug und Flughafen sowie der Ausbildung der
Piloten.

Das Flugzeug: Sieben Eurojets der Luxair wurden mit dem
HGS-System ausgerüstet. Kostenpunkt pro Flugzeug: rund 1,1
Million Euro. Sichtbarstes Teil ist eine kleine Plexiglasscheibe, die im
Cockpit vor die Windschutzscheibe ins direkte Blickfeld des Piloten
geklappt wird. Auf diese "Brille" werden von einem Projektor Zahlen
und Symbole eingespiegelt, die Fluglage, Flugrichtung, Gleitwinkel,
Höhe und Geschwindigkeit darstellen. Auf diese Weise erhält der
Pilot zwar nur eine künstliche, aber dafür äußerst präzise Darstellung
seines Flugweges und kann sich voll auf das Steuern seines
Flugzeugs konzentrieren. "Bei Nebel behält der Pilot trotzdem den
Durchblick", erklärt Luxair-Chefpilot Philippe Oberbillig.

Dies ist besonders wichtig kurz vor dem
Aufsetzen: In einer genau festgelegten Höhe
über der Piste muss der Pilot entscheiden, ob
er landet oder durchstartet. Durch den Einsatz
des HGS-Systems konnte diese sogenannte
Entscheidungshöhe für die Eurojets auf 15
Meter herabgesetzt werden.

Neben der technischen Zertifikationsprozedur
musste Luxair während der operationellen
Demonstrationsphase insgesamt 46 Anflüge
mit dem System durchführen um die
Betriebserlaubnis für das HGS zu erhalten. Bei
95 Prozent dieser Anflüge mussten die Abweichungen nachweislich
innerhalb sehr strengen Toleranzwerten bleiben-, ohne dass ein
Durchstartmanöver nötig gewesen wäre. Umrüstung der Maschinen
und Zertifizierung dauerten insgesamt neun Monate.

Der Flughafen: Unter welchen Bedingungen ein Flugzeug auf einem
Flughafen mit Hilfe des ILS (Instrument Landing System) starten oder
landen kann, ist genau geregelt. Entscheidende Größen sind die
vertikale und horizontale Sichtweite.

Gerade auf dem Findel kann schlechtes Wetter den Flugbetrieb
erheblich stören. Knapp hundert Stunden pro Jahr sinkt die Sicht
unter die magische Grenze von 300 Metern. Besonders anfällig sind
die Monate November (20 Stunden), Dezember (15), Januar (24) und
Februar (14). Zudem ist die Start- und Landebahn des Flughafens
Findel nur in südwestlicher Richtung für den Instrumentenanflug
nach Category III ausgerüstet.

Die Luxair-Eurojets mit HGS sind für Landungen nach den
sogenannten CatIIIa-Regeln zugelassen. Hier liegen die
Mindestsicht weiten auf Pistenhöhe bei 15 Metern in der Vertikalen
und 200 Metern in der Horizontalen. Beim Start gelten 75 Meter
horizontale Sichtweite als unterste Grenze. Bisher lag dieses Limit
bei 125 Metern.

Die Piloten: Alle 65 Eurojet-Piloten der Luxair haben eine besondere
Schulung absolviert, um den Umgang mit dem neuen System zu
üben. Diese Phase nimmt ins- gesamt pro Pilot sechs Wochen
theoretische Einweisung, Training im Simulator und Training auf der
Linie in Anspruch. Jeder Pilot muss mindestens 20 Landungen mit
dem "Head Up Guidance System" absolvieren, Flugkapitäne sogar
40 - bei gutem Wetter. Erst wenn dieses Training abgeschlossen ist,
folgen echte Schlecht-Wetter-Anflüge. Anders als bei größeren
Flugzeugen wie der Boeing 737, die im Instrumentenflug vom
Autopiloten "geflogen" werden, führt der Eurojet-Pilot mit dem HGS
auch bei schlechter Sicht die Landung eigenhändig durch.

Piloten müssen bei jedem Flug vorsorgen für den Fall, dass sie bei
schlechtem Wetter nicht auf ihrem Zielflughafen landen können. Die
Planung eines eventuell erforderlichen zweiten Ausweichflughafens
wird bei einem Flug mit HGS stark vereinfacht und reduziert
dementsprechend die Kosten für zusätzlichen Treibstoff sowie das
Risiko von Verspätungen für die Passagiere.

Mit der neuen Ausrüstung und der CatIII-Zulassung dagegen können
sich die Luxair-Eurojets auch bei sehr schlechtem Wetter meistens
mit nur einem Ausweichflughafen begnügen. Piloten und Passgiere
haben damit im wahrsten Sinn des Wortes bessere Aussichten auf
eine sichere und pünktliche Landung.

Greetings

Well, I have no idea of what it says, but in the US: Southwest, ALaska, and Horizon I know for sure have them in some of their aircraft. I believe AA has them in some of their 737's, well were at least looking at them while I was there. I doknow of some corporate aircraft with them as well, was in an GV that had one

I remember reading in Kitplanes magazine (back in '91 I think) a series on how to build a HUD for your home-built. It involved cannibalizing an IBM PC and hooking it up to a bunch of sensors and an LCD projection screen of some type. I didn't understand a whole lot about electronics back then, and it looked like a complicated mess, but it can be done!

Hi there
I posted a topic about the Luxair Eurojets a couple of days ago though I have to assume that your post is a little more detailed

http://www.airliners.net/discussions/tech_ops/read.main/30424/

As for the HUDs in civil a/c I just know that some of Swissair's MD 80's, if not all,were equipped with them thus being among the first airliners in the world to have an head up display.I'm not sure if other carriers have followed Swissair 's example in the eighties but I' m pretty sure there are. Luxair is "only" the first ERJ145-operator to order HUD's for their a/c.  Wink/being sarcastic

Regards,
Ganymed

As far as I remember, Air Intaer (former French domestic carrier) has been the first airline using HUD on commercial jets.
It was the Dassault Mercure.
Today, Mercure are not flying anymore, but you can see one at Le Bouget museum.
NAna...

Okay, I'll try to translate it:

Not without pride wise Luxair pilot in these days on a pioneer work at the Eurojet fleet. As first airline of the world the of Luxembourg airline uses a flight assistance device on their short and medium range jets of the type Embraer ERJ-145, the so-called " Head UP Guidance system ". This technique gives it of course for many years, was used so far however almost exclusively in military aircraft.

The new equipment supports the pilot with bad visibilities such as nebulas or strong rain as well as with the landing on airports with difficult approach procedure. The " Head UP Guidance system " is besides a prerequisite for the fact that the ERJ-145 could become certified the Luxair for the instrumentation after stricter conditions.

For euro jet passengers the application of the HGS can mean that they come safe and more punctually to the target - even if they do not notice it at all. Because whether a machine lands according to plan or starts with adverse weather conditions, it decides not least due to a strictly regulated interaction between the technical equipment of airplane and airport as well as the formation of the pilots

The airplane: Filters Eurojets of the Luxair were equipped with the HGS system. Matter of expense per airplane: approximately 1.1 million euro. Most visible section is a small plexiglass disk, which is folded in the cockpit before the windshield in the direct field of vision of the pilot. On this " eyeglasses " by a projector numbers and symbols are in-reflected, which flight attitude, flight direction, gliding angle, height and rate to represent. In this way the pilot receives only an artificial, but but extremely precise representation of his flight route and can fully on controlling his airplane concentrate. " with fog the pilot keeps nevertheless looks through ", explains Luxair chief pilot Philippe Uppercheaply.

This is particularly importantly short before putting: In an exactly determined height over the runway the pilot must decide whether he lands or waves off. This so-called decision height for the euro jets could be lowered by the application of the HGS system to 15 meters.

Apart from the technical certification procedure lux air had to execute 46 approaches with the system during the operational demonstration phase altogether around the operating permit for the HGS to receive. With 95 per cent of these approaches the deviations had to remain provable within very strict tolerance values -, without an auto restart maneuver would have been necessary. Re-equipment of the machines and certifying took altogether nine months.

The airport: Under which conditions an airplane on an airport can start with the help of the ILS (instrument Landing system) or land, is exactly regulated. Crucial sizes are the vertical and horizontal range of vision

Even one on the Findel can disturb bad weather the flying operation substantially. Scarcely hundred hours per year the view sinks under the magic boundary of 300 meters. The months are particularly susceptible November (20 hours), December (15), January (24) and February (14). Besides the start and runway of the airport Findel are equipped only in southwest direction for the instrumentenanflug toward Category III

The Luxair-Eurojets with HGS are certified for landings according to the so-called CatIIIa rules. Here are the minimum view widen on runway height with 15 meters in the vertical one and 200 meters in the horizontals. When starting 75 meters horizontal range of vision apply as lowest boundary. So far this limit was with 125 meters.

The pilots: All 65 euro jet pilots of the Luxair completed a special training, in order to practice handling the new system. This phase takes entirely per pilot six weeks theoretical briefing, training in the simulator and training on the line to in up. Each pilot must complete at least 20 landings with the " Head UP Guidance system ", flight captains even 40 - in good weather. Only if this training is final, genuine approaches of bad weather follow. Differently than with larger airplanes like the Boeing 737, which become " flown " in the instrument flight of the autopilot, the euro jet pilot with the HGS executes the landing also with poor visibility personally.

Pilots must it with each flight to take precautions if in bad weather on their target airport to land not be able. The planning of a possibly necessary second alternate airport is highly simplified with a flight with HGS and reduced accordingly the costs of additional fuel as well as the risk of delays of the passengers

With the new equipment and the CatIII permission against it the Luxair-Eurojets can mostly be content also in very bad weather with only one alternate airport. To pilots and pass-crave have thereby in the wahrsten sense of the word better prospects on a safe and punctual landing.





The meaning of life is curiosity; we were put on this planet to explore opportunities.

Thanks Lepron for the translation I didn't had the time to do it myself yesterday (I have
to work somethimes between my posts  Smile/happy/getting dizzy )

Ganymed you're right I saw this in the LW newspaper. BTW Ganymed, I love Luxair's
ERJ's  Smile/happy/getting dizzy
