When I climb and I am close to 30000ft, the speeds drop down slowly to about 150knots. The thrust is at maximum, OAT is -40 and VS is 1500.

Is it makes sense? I dont think this should be a climb speed for a jet...

I usually use the IAS feature and set the initial climb speed to 225 knots. I start out in the 3,000 fpm or greater area and end up around 1,000 fpm in the low FL3xx. I would think something like 190 kts would be the lower climb speed if you were not using IAS.

 

Check the Performance Charts for the Climb/Cruise tables that came with SP1.

1500fpm around FL300 is far far far far far to much for the S550!

 

Have a look into the Performance Manuals, in there you will find the speed schedules for it.

Out of the head I think around 200kt are the cruise climb speed around FL300, which leads to a VS somewhere near 800fpm or so.

The speed  for the best rate of climb is indeed going to be somewhere near 150kt I believe. Have a look into the manual to find it.

I usually use the IAS feature and set the climb speeds:

< FL150 ......... 210 KIAS

FL150 - FL250 ... 200 KIAS

FL250 - FL350 ... 190 KIAS

> FL350 ......... 185 KIAS

 

 

I start out in the 3,000 fpm or greater area

 

Haha, funny I remember when you said that it was not possible and it was just for "marketing purposes"...now you can see that it can climb at 3,000fpm????? and it's almost the normal climb rate after take off???

I agree 150 knots is slow, I use a little mod for the engine to get better performance at high alttitudes, I'm not a fan of taking almost 1 hour to get into FL350 and above, when the real aircraft climbs pretty fast, and I also use the IAS feature

That's not what he stated in this thread, at all. He simply stated what he's seeing happen in the sim.

I never said that he said it here in this thread...we also state what we see on the sim...

jjmp,

 

I think you have me confused with one of KenG's comments and if so you have taken the 3,000 fpm initial climb rate at sea level way out of context.

 

KenG said "You are not going to get 3,000 fpm in the upper atmosphere. That is an ISA number useful only for marketing."

My comments to you were about double dipping when adding to the thrust_scalar and also to the static_thrust. None of the early Citation have been built with as much power vs the airplane weight as you have added. Sure yours will now climb like a rocket, but then you have no references for realistic rates, speeds, fuel flows, etc. I would think your rw airplane buddy would know that.

 

There was an initial Carenado release that had very weak high altitude climb rates, and some folks made some thrust adjustments in the aircraft.cfg file. Then when we got a new air.file with SP1 and a slight thrust adjustment then the climb rates were increased to be more in line with the rw airplane.

 

For this S/II, I personally think any more thrust than SIJET is adding with their Williams FJ44-3A engine upgrade is excessive, but that is just my opinion. Hell, why not buy the new X-15A-2 SE and strap your S/II onto it and you can go to 200,000 feet and mach 6.

 

I don't remember me ever saying anything that used marketing and climb rate in the same sentence - in any thread or forum. Can you come up with it?

Oh yeah, I got confused with KenG post, thanks for clarify!
