i think these planes are underpowered

Get your hands on A320 professional by Just Flight if you want an accurately modeled plane. No problems with the settings! Just do not stall as it goes into Alpha-floor and you can't recover.....not good!

i think what your talking about is the update for the a320. You have to purchase the original, if I am correct. Please tell me if I am correct in my assumptions

Hi,
I have been downloading a few airbuses lately, but they all seem REALLY underpowered. I just got an a321 and it was set at 31,000lbs of thrust, but i adjusted that to 40,000. At intial climb, I set the IAS to 260 KTS, but at 20,000ft, it started to lose IAS fairly quickly. I adjusted the VSR to 1200 fpm, but it didn't change its condition. This seems very unlikely, considering it had so much thrust. Can anyone suggest something useful for me to change. BTW, the A321 is supposed to cruise at .78 mach at 35,000ft. Thanks and Happy Holidays

yust in las put a higher speed dumb

Hey guest hav u beeen dinking d wine?

yust in las put a higher speed dumb

First, Don't insult crosscheck9, he's a awesome member of this site, and has supplied much information and knowlege.

Secondly, seeing is how you know so much, enough to call him a dumb ass, (yes, thats what you're thinking, im not stupid) you would know that putting in a higher speed would do no good. God, i thought you KNEW this because you're so smart. I'm SURE you don't need to hear this, but seeing is how you want to insult a good friend of this site, you SHOULD know this...putting in a higher speed does no good, because obviously the engine can't put out enough power to push the aircraft at 260 kias, what makes you think that you'll be able to make it fly faster? God you're dumb. Come ON, you KNOW THIS!!! You HAVE TO, because you WOULDNT insult someone if you DID, would you?!

Why don't you come back to this site when you've adjusted your atitude, we don't need your bullshit here.

Crosscheck9, sorry you had to take that from whoever that guest was, maybe this info will help you.

NOTE, TO FIND THE ACTUAL THRUST OUTPUT WHEN MODIFYING THE THRUST SCALAR IS SIMPLE, MULTIPLY THE MAX THRUST NUMBER, IN YOUR CASE, 40,000LB, BY THE THRUST SCALAR.

EX. 40,000 X 1.2 GIVES 48,000LB THRUST.
THIS IS USED INSTEAD OF THE ACTUAL THRUST RATING, SO THE FUEL BURN IS NOT AFFECTED. IF YOU MODIFY THE THRUST RATING, LIKE YOU DID, TO 40,000LB, IT BURNS MORE FUEL. I DONT KNOW THE FORMULA FOR IT.

Sorry for "Shouting" but it's easier for you to find it that way.

THE FORMULA FOR THIS IS SIMPLE, 1.0 GIVES 100% OF THE MAXIMUM THRUST. 1.1 GIVES 110%

2.0 GIVES 200%.

hey....thanks alot FEM, your right, i dont need to take that kind of insult from some1 i know nothing about. Thanks for the information too, Happy holidays and once again, thanks alot FEM

I do what i can, let me know if it fixes your problem, or if you need more help

Guys when I read how you hammer, I think you miss the meaning off live. Be patient and run for some fun. Boys (and you are boys with this temper) you are rude....

a bit late, just over two years, but I am sure he'd thank you for the compliment all the same :p

Sorry ARD_DC just commented after last post ,should have checked the dates!
