Title: Some doubt about EPR and Vbugs setting!!!
Post by alligator on Dec 29th, 2010 at 10:30pm
I'm reading the operation's manual, but I don't find any EPR table setting  for T.O., climb, cruise or go around. Anybody know the right setting???
And on the T.O. and approach tables, where we should get the V1,VR, V2 and flap retraction speed, the wieghts are incorrect because  the 727-100 has a MTOW  of 160000 pounds but on table, the weight is listed up to 210000 pounds and starts from 120000 pounds!!!! I think these weights are related to the 727-200!!!!!
So, there are some table related the 727-100???

You'll find that data in QRH provided by "The Other Developer", I have no idea why CS didn't include this information with their product, it's just few pdf pages more...

Yeah!!! You'r right!!!!
And I'd like to know How the people can fly a heavy aircraft without this important data???!!!!  :(
And I'd like to know why Captainsim doesn't make a loadmanager where we can calculate ZF CG  and  TO CG!!!!  and so estimate the right setting for the trim tab!!!!   :-?

On the other hand, according to QRH I should be able to get M.80 with 1.85 EPR at gross weight of 130000, FL350 and SAT at least -54C, but in fact I need 2.19 EPR with SAT -58C.  Obviously there's huge possibility that it's me doing something wrong, because I'm not very experienced with this kind of aircrafts, so if anyone can provide some detailed explanation I would be very thankful.

Grzegorz

Thanks asanal!!!  :D
Now it seem to be a great airplane!!! And now with right EPR, MAC and TAT is more real and I can enjoy a real flight!!!
I tried these mod and it looks great!!!!
But the only think that I don't appreciate is the  attitude that seems to be too high during high speed, e.g. during cruise,
Anyway it is mutch better than before!!!!
Thanks a lot and thanks to Michael!!!!   ;)

I'm glad your enjoying my modifications.  From what I can gather, it should cruise at about 3' nose up. I don't remember off hand what it's doing in the sim, but I think I was close.  Changing it is not so simple, as then you have to make other changes to get it to have the right attitude on approach without changing the fuel burn and power settings and so on.

I am about ready to distribute a similar package for the 200.

Hi Michael,
I think you have done a great job, and imagine it  was not simple as you said!!!!
A problem is also (for me) the low resolution of the attitude indicator and is pretty difficult read the right attitude!!!! Maybe is only a my opinion!!!!
But I'm shure the attitude in cruise is too high!!!
Anyway.... michael congratulation for your job!!!  ;)

Thanks for your encouragement!

The tooltip for the autopilot pitch control will give you an accurate pitch value.  The artificial horizon is not so good, as you point out.

Michael thank You for your corrections to this airplane, now it behaves as expected. I'm surprised that CS didn't include this mod in their product yet!

THANK YOU! And thanks to Asanal for pointing those corrections!
