Cooley! Thank you so much! This is VERY informative! I'm going to plan another flight issuing the new climb profile you suggested and the V/S method. I have actually been using only the SPD Mode for FLCH. I will be sure to do this. Also, I have noticed in the JROLLON CRJ that the CLB thrust is always higher than the TO thrust. In other aircraft that I have studied... It is always the opposite. Is it like that in RW? Do you fly the JROLLON CRJ? If so, do you plan your flights with the real world charts? (I can give them to you if you don't have them anymore) and does it act right for you?

Sir, you do understand that I speak of "Optimum Cruise Altitude" for EFFICIENCY..... Not the "Maximum Operating Altitude"... Right? For example... that charts says at a weight of 21,000kg GW... and an ISA + 5c, you WANT to be at FL350 for optimum fuel burn vs output.... but at that weight and ISA deviation.... you technically COULD be at FL370 but you will not exactly get the best economy/efficiency. Therefore im not "PUSHING ITS LIMITS" at all... That would be going up to FL370... I want FL350 for efficiency for this example. Please send me an email address so I can show you the charts Thank you for understanding my point. So you think I should use the 250/310/M.77 Climb Profile? I used that once... it took me for a very slow climb but at a higher pace. I guess that would be ok for a long distance flight... with that CLB profile it would take almost 30% of your trip disntace which is the limit for a selected altitude.

Additinally- the airliners have dispatchers to do ALL these calculations for them. I dont have that. The dispatchers have software that does all these calculations for them. I dont have that. What I "DO" have is the paper work that the software is built off of. I have the time to sit down for a couple hours, assess the winds, ISA deviations, Pressure altitudes, Weight and Balance, ect... So i now want to be able to take that information and input it into charts then FLY the CRJ the way it is SUPPOSE to be flown. I think that sums it up lol

Horani, like I said before, it is not so much as what other airliners do for their routes, im trying to get the CRJ2 to act like the charts SAY it should. If they do not usually fly that high, the I can live with that, but I want an accurate flight planning charts for the JROLLON CRJ2. Further more, there ARE flights that go to higher like you said, the FL330 guy... that ONE exception is all that counts.. he went up there.... Now HOW did he go up there? I thank you for the link to the forum there, but im not so sure I want to go in there and be all "Well my sim does this".... Not sure if they would understand what im trying to do. I have heard of that event with the crash on the empty CRJ2. Horrible event... but regardless... as I told Horani, I still want to be able to ACCURATELY plan my flights.... I want to be able to: Know EXACTLY how much im going to weight for Ramp, Taxi, Ramp, Takeoff, Thrust Reduction, How long it is going to take to CLB to CRZ ALT... WHAT my CRZ ALT will be for MAX efficientcy... My DES planned and know how much fuel i will use for EACH phase of the flight, thrust limits for each phase (i know it is already simulated), How am i going to climb?- 250/290/M.74?.... 250/M.74?... 250/320/M.77? What the time and fuel needed for each version with regards to pressure altitude and ISA deviation.... I can keep going... but i think you guys get the idea.

Horani, I have looked at EVERY one of these flights and 90% of them were above F280. The top i found was FL350 in there. The real world charts that im referring to is a download that I have. I will give it to you but i need an email address to send to. I am not allowed to post copywrite material here (my first post i referenced in this thread had some explaining my flight planning but was removed from the thread)
-
1) you are correct, I usually see FL for CRZ in between FL240-FL320. It is rare but I have seen them higher. 2) Regardless of what normal AIRLINER COMPANIES do.. I am going by what the CHARTS say it can do. My KATL-CYYZ trip with 32PAX and 28 pieces of luggage then plus the fuel and all other calculations, the real world charts say that FL380 is not only capable, it is the Optimum Cruise Altitude for that weight and ISA deviation. I had to take it down to FL370 due to SWEVEN/NEODD rules. but the CRJ did not even make that. It caped off at 300ft/min ceiling at FL260. 3) are you a real world CRJ2 pilot? 4) I would be happy to share my real world charts with you for review but it cant be here due to copywrite.

Hello to the GREAT CRJ-200 community. I am looking for real world CRJ-200 pilots to take a look at my planning in a specific situation and be able to tell me if I am doing something wrong. Please reference this discussion and then contact me with any questions. I will provide real world pilots of a step by step instruction of how I came up with my values upon request. (it will take a while to write it but if it means that I can learn how to fly the CRJ better and more accurately, then I am willing to do that) It would be a shame to have to stop flying the JROLLON CRJ2 if I can't figure this out http://forums.x-pilot.com/index.php/topic/4405-solved-inaccurate-performance-vs-real-world-charts/

[SOLVED] Inaccurate Performance vs REAL world charts
Kyle Sanders posted a topic in Canadair CRJ-200
Attachment removed: uploading of copyrighted content not permitted! I have the ability to get my hands on the real world CRJ-200 performance planning charts. I have been able to now FULLY plan EVERY aspect of my flights. I am now saddened due to the fact that I have realized the JROLLON CRJ2 does not perform the way that the real world charts say it should. Now where NEAR it. I am not sure if you MEANT to have it perform differently or not but here is my assessment: FLIGHT: KATL-CYYZ Planned distance 787nm CONDITIONS: (without going too far into detail of HOW I cam up with the fuel and weight of the aircraft) ___X-Plane 9.70 JORDAN CRJ2 1.4.5 (refer to my signature) ___Initial GW: roughly 21,000KG ___ISA - 10C ___NORMAL A/C ___A/I off ___Thrust limits- as calculated via FMC (t/o, clb, crz, etc...) CLB Profile: 250/290/M.74 300ft/min climb ceiling At FL370 the rate of climb should be 500ft/min shown by provided chart CRZ: M.77 FL370 (capable of F380 but due to SWEVEN/NEODD rules, we drop down to FL370) I wish I could sit here and Explain my EVERY move with these charts but it would take a WEEK to write that book. I have attached here all the documents needed to plan this route. I have left out simple things such as the T/O thrust, time, descent planning so that I may only convey my point here. WHAT ACTUALLY HAPPENED: __FL260 = 300ft/min top out. __I pushed it out using V/S 300ft/min and disregarding my Mach speed __Taking twice as long to climb as it was suppose to __Got to FL365 and the CRJ started to dive. Javier or Cameron, You may contact me for the ENTIRE planning documents if you wish. -
Hello Cameron, I was just threading with you in the .org. Sorry about that. for some reason I thought I was in the XA forum. Could please describe how I may downgrade to 1.4.5 from 1.5.2? I am experiencing random crashing with XP9. I figure it is due to the upgrade to 1.5.2
-
I know about that and I have done ALL the common "troubleshooting" steps before my VERY... VERY HARD decision to re-install everything. But i thank you for the offer of info.
-
This was happening to me recently. I had to delete both XP10 and 9. Then re-enstall ALL plug-ins from scratch. Reset everything. Re-enstall all my payware aircraft. Now everything is running smoothly.
-
Auto-Throttle and VNAV did not come to the CRJ until the CRJ-900 I believe. Then it was only programed into the FMS if the airline company WANTED it and had to pay extra. Along with T/D and things of that sort.

Hello, I am posting here because I use the CRJ2 for 99% of all my flights and the following scenario is applicable to the CRJ2. With the attached document in mind for a flight from KMIA-KATL in the CRJ2 (i know it is a bit far but just for this example) I have done my load planning and fuel planning. I have figured that my TOW is going to be about 20,000kg. I have looked up the KMIA METAR and it is 25C. Which is 10 degrees Celsius higher than the ISA standard: "15C at sea level" So I figure that the ISA deviation is +10C. (this is the part im not sure if im doing correct) So now I go to that chart and do the math. I see that the 20,000kg goes up and meets the "ISA +10C" line. Where those two meet, I see that it is at FL380. (rounded up for CLB fuel burn) Am I doing this correctly?CRJ Flight Planning LRC.pdf

Thank you sir. That answered my questions! thanks!

I have been out of the loop for the past 6 months with x-plane in general. I have just re-downloaded the CRJ2 from my X-Aviation account. It says that it is 1.5.2 but I am seeing posts in some places about people running 1.5.3. I googled and found that 1.5.3 has something to do with 64bit in XP10. I have also seen that if I update to 1.5.3 I MUST use 64bit and if i want to use 32bit i MUST use 1.4.5. I run X-PLANE 9.70 on my iMac (details in my signature) and I am having certain issues with it that i have previously posted about. I would really just like some clarity please?

Engine Spool up problems (after landing)
Kyle Sanders replied to Kyle Sanders's topic in Canadair CRJ-200
1) I use the standard procedure of ARMING the Reverse Thrusters on final, Then I land. They then automatically Activate (which they should) but then they actually spool up without me advancing them (which they shouldn't and never have until this version). I got ahead and advance the throttle levers anyways so that I can bring them to Idle once I hit 80kts. But the fact that they advance on their own may be part of my problem. (I use the Period key for the DEACTIVATION of the reversers once they are brought to Idle) I then taxi off the runway, hold short of the next taxiway, get taxi instructions, then advance my throttle to taxi thrust but it takes a LONG time for it to spool up from there. RIDICULOUSLY long to the point where I have to disconnect from VATSIM because im just sitting there taxiing up a runway exit. This is a BIG problem for me. 2) X-PLANE NAV DATA is using 1208. I have that. I made a mistake. But NAVIGRAPH (CRJ data) is using 1212 now. I have just changed this in my signature. Thanks for the catch! -
Hello, I have ad this problem in previous version of the CRJ2 but now it seems to happen ONLY every time I land. I say "Every Time" but I have only had two flights with it. Both were on the VATSIM network. I follow the checklist attached to this post to the TEE. (i made it). WHAT HAPPENS: -I land. -Spoilers deploy -REV THRUST is automatically engaged and brought to full by itself (this use to not happen, why does it come up by itself?, I have went ahead and advanced the throttle as well just in case and that allows me to retard the reverse thrust after passing 80kts- This could be effecting the problem) -I exit the runway. -Hold short of the next taxiway and prepare the aircraft for taxi -Advance the throttle levers about 3/4's N1 and N2 take about 40sec to spool up to desired thrust. What is going on? This makes it to where i cannot get out of the way of other arriving traffic. I dont believe that this is a new problem, because this use to happen to me around the beginning of this year but it usually happened randomly on the ground while taxiing to the runway. I have talked to other users and they have not experienced this problem. JROLLON CRJ200 CHECKLIST.pdf

Sir, Please forgive my previous, Stupid question about the updated Spread Sheet. I really like what you have done with the CRJ Spread Sheet. I have attached the picture of the first page of a REALLY great manual I have got my hands on. I think you could use it. The agreement is that you do not share it with anyone. You keep it private. Please let me know if you agree to this and I will send the 70mb document via a DropBox link. I have noticed that your spreadsheet is only missing 2 things. 1) Optimum Cruise Altitude Selection calculation. (AKA- "LRC") 2) Speed calculations. Both of these tables are found in the manual I have. Please let me know if you are interested.

jagipson, I have been searching since the initial release if the JR CRJ2 for exactly what you guys are doing!!!! Thank you so much! May I get the link to your most up to date planning sheet? I see that you have updated it to display wet vs dry but I don't see a link to the updated version. I am on my cellphone right now and can't open any if them- are they all the same link and is just continued to be updated automatically?
-
Well this is informative. I'm on my cell right now... Do you har these updated charts?
-
Hello, I am wondering if the JROLLON CRJ2 is programed according to Bombardier LRC charts. I planned a flight yesterday from KATL-KTPA and had planned for FL390 according to many calculations but the most important one being the LRC altitude selection chart (attached) which said I should be at FL390. But I reached the 300ft/min climb ceiling at FL330 and had to level off there. CRJ Flight Planning LRC.pdf

Actually this is a very old post. I have fixed the problem. I was opening the XFLOW and taxiing... that shot all the fuel very easily to one side. So i do not open the Flow at all now. I have talked to real CRJ pilots and have revised the checklist. It is attached to this message here. I hope you find it useful
-
C729!!!!! p.10 is pretty much exactly what i was looking for! can you tell me where you got all this and can you email me at ksanders7070@gmail.com for further conversation. I have some questions if you dont mind?

Chris, Yes I have found that it is nearly impossible to calculate this OPFL manually lol I have spoke to real regional airline pilots about this and it is a specialized software the company has and is automated and is sent to the FMC of the aircraft via the ACARS system. If you see on places like Flightaware.con you will see the climb to cruise takes about 1/3 if the flight time in a CRJ and then they stay at cruise for about 5-15min the star a descent. This is rediculous to me!!!! But in the end- it is apparently fuel efficient to keep climbing to that higher cruise altitude then it would be to level off at a lower altitude for a return of longer cruise phase. Hope this helps.

Chris- Update is that the person who PROGRAMS the site for me is currently unavailable.. real world stuff got in the way. I have updated many sections of the 737 checklist. Mike- Thank you. we have received this request many times. i wish i could update the page but idk how to do that. and I'm waiting on the programmer to be available right now. We are still working on those advanced features. They take some time lol Also- the mobile version is being worked on as well. That will hopefully be fixed by first RC1. C729- ATTACHED to this post is my most recent version of the CRJ2 checklist that i have remapped. in the FILES section of this Facebook group you can find the most up to date one as well. https://www.facebook...25503114156549/ Why did you give me JROLLONs email and info?
