Takeoff distance will definitely be increased. I think you'll be down about 600 pounds of thrust by 6-7K. However, that climb speed seems a bit anemic, but I'll see if we have anything in our references. At an airfield like KJAC be sure to spool up fully and let the engines settle before releasing the brakes.

 

That seems like too high an IAS selection. Best climb speed in the CJ4 is actually 160kts, but 240kts is usually used. I usually can get 1500fpm still at 30K.

@FNAL, our resident CJ4 pilot may also have some suggestions as well. I'll definitely try flying out of KJAC and see what it looks like.

Thanks Matt!  Another question, is there a way to display ground speed on the PFD?

Thanks for the Update. A few things i've picked up with the recent version.

- CRS 2 knob does not change VOR 2 course when in VOR 2 display mode. Both CRS 1 and CRS 2 knobs can change VOR 1 Course.

- COM 2 receive Button toggles VOR 2 on/off.

-Weights on the perf page don't add up to indicate proper ZFW or TOW. It shows 190lbs per pax where the default weight reads 170lbs.

- Approach speed page is blank, after putting in landing data.

Thanks for your efforts on this, it just keeps getting better and better!

Impressive patch work judging from the video preview.  Nice to have a much more functional FMC.  Look forward to trying it.  

Many thanks for all your work.

No problem!

There isn't a way to my knowledge but GS does display on the bottom of the MFD.

Thanks you.  Let us know what you think of the performance out of KJAC.

just a work in progress, still working on adjusting the N1% settings to match, but these should be close to RW values.

Tried a flight out of KJAC-KISM.  The plane almost took the whole runway to take off and climb out averaged 1500fpm.  There was no way I was getting to 38,000ft and I didn’t have a heavy load. 

Two questions:

1. Is the CJ4 that affected by high altitude airports that it needs a considerably longer takeoff distance?  KJAC was cool and usually this is a problem for pitons not jets.  Again my weight was light with only 86% fuel.

2. Is it normal with light weight and low upper level winds when you get up around 23,000ft your climb rate is reduced to 1,000fpm?  Even with version three the CJ4 struggled past 24,000ft.

Something doesn't seem right here.  I haven't had any problems with climbing and you should be around 1500-2000fpm climbing at 240 kts in the 20s.  Expect 1000 or less when you get into the high 30s.  

I will fly out of JAC and check performance.

CRS 2 is bugged/not implemented by Asobo and it's on our lsit.  

Weights page needs to be changed and updated correctly with what is on the sim W&B menu.

-Did you have a landing runway in there?  It currently crashes when there is no runway heading when it calculates the wind components, we will fix it.

Marc,

Is it possible for you to provide these CJ4 Patterns with a white background and black text so they can be printed? Thanks.

Regards,

Ray

Looking good. Finally able to edit routes manually on FMS is wonderful and the fuel consumption is spot on (with maybe a 15-20% error margin).

However, I was unable to enter an airway. Since it may be my fault, maybe someone can check it or correct me.

My route was KDAB OMN SEBAG SSI KELER SAV SPONG V185 BEANS KAGS.

1) If I enter SPONG and then BEANS and try to replace DIRECT with V185 nothing happens.

2) If I try to enter V185 it says no exit fix.

I'm not in sim right now, but have you tried to NOT enter BEANS until AFTER you enter V185 on left side THEN to the right of V185 enter BEANS ?

@shadow133 This is the proper procedure. After you have:

DIRECT            SPONG

Then type V185 into the scratchpad, click the LEFT lsk on the line below DIRECT and after that enter BEANS in the scratchpad and click the RIGHT lsk on the line you added V185. That should do it.

I have been using VS for climbs.  Is FLC working? I have been using 2500-3000fpm up to 10k, approx 2000fpm to 20k and lowering as needed from there. Any pointers on best practices for the climb out? Thanks again.. only plane I fly at the moment!

FLC does work for me, but others have had trouble with it. FLC needs to be used with kid gloves.

Typically I will set FLC to 250kts and LNAV on the runway, with FD on and AP off. I take off, clean up, reduce power to CL and then get established in the climb, properly trimmed. Once I pass 200kts, I will enable the A/P and it will do it's thing on FLC and LNAV. I tend to climb at 250 to 25,000, then 240, then reduce further as needed with altitude.

By about 30k you'll need the throttle at full again, since we don't have the FADEC doing that for us (yet)...

Climb rates should be as FNAL said, in the 3700-4000 range below 10k, then about 3000-3500 until 20k, in the 2ks while in the 20s and then in the 1k fpm range by the mid 30s...
