Meljet 747-400

[AlexP]

Hi !
Ich hab da ein kleines aber feines Probelem.
Ich hab mir ne Aircraft.cfg + PSS747 Airfile + Loadmanager eingebaut in die MEL747.

Jetzt hab ich ne Frage:
Ist es normal das wenn ich ein ZFW von 511615lbs habe und 323345lbs TReibstoff an Bord habe das sich die Nase von meinem Jumbo bei Flaps 20° erst bei 187kts anheben lässt?


Danke !

[Nikolai]

Hast du die PSS-Kompatibilitäts-Aircraft.cfg von MelJet verwendet (ganz unten auf der Downloadsite)?

[Sam, LSZE]

Hallo

Da ich momentan an keinem Rechner mit Flusi sitze, kann ich nicht nachgucken. Meiner Meinung nach ist das aber zu hoch für VR.

Was hat dir das FMC für Geschwindigkeiten angezeigt?

Wie hast du die Maschine getrimmt? Bei mir muss die Trimmung zwischen 8 und 8.5 stehen. Dann hält sich die Maschine wunderbar an die im FMC errechneten Werte.

[HeinzS]

wobei bei Marke Eigenbau

Oder schau mal in de Charts.

[AlexP]

Hi !
Also
1.Es ist deine .cfg Sam
2.Ich hab die von Meljet nicht weil dort die Slats nicht ausfahren...


Weiß einer warum?
Dann nehm ich die und ändere sie wenn mir jemand en Eintrag sagt.

Zur Trimmung:
Hab alles probiert, überall das selbe.

Hi,
hier ist meine Aircraft.cfg zur Meljet 747-400.
Leider muss ich sie Teilen,Beitrag ist zu lang....

So und jetzt sag mir einer mal bitte wieso ich verdammt einen sooooo hohen Vr Rate hab.

[FlusiRainer]

Meistens liegt es an der Flügelfläche.Wenn mich nicht alles täuscht,stand in einer der letzten FXP etwas dazu,das man die Fläche in Verlängerung der Vorder- und Hinterkante bis zur Längsachse mit einbeziehen soll.
Ich selbst mache es schon immer so,das ich die in technischen Daten angegebene Flügelfläche um ca. 15-25% erhöhe.

Das wäre dieser hier.
[airplane_geometry]
wing_area=5650.000000


Anschliessend müsstest Du den Anstellwinkel der Tragfläche zum Rumpf korregieren,um den Reiseflug mit einen leichten pos. Pitch fliegen zu können.

Das wäre dieser hier.(ebenfalls unter [airplane_geometry])
wing_incidence=0.999756


Und zum schluss noch die Auftriebswerte der Landeklappen überarbeiten.

Das wäre dieser hier.(findest Du unter[flaps.0]
lift_scalar = 0.55

Die 744 sollte nach ner Langstrecke im Endanflug mit fullFlaps etwa mit 145-150KIAS bei pos. Pitch bis 5° einschweben.


Da muss man mit den Einstellungen ein bischen experimentieren,bis man den besten Kompromiss von Start über Reiseflug bis Landung hinbekommt.

[Sam, LSZE]

....ob deine VR auch im FMC so hoch errechnet wird, oder du erst bei dieser Geschwindigkeit rotieren kannst, obwohl das FMC eine deutlich tiefere VR errechnet hat?

Mit der Aircraft.cfg, welche du von mir hattest und dem Airfile von PSS stimmen bei mir die errechneten Geschwindigkeiten mit den tatsächlichen mehr oder weniger genau überrein (vorrausgesetzt, die Maschine ist richtig getrimmt)
