Hi Guys,

 

I've been using RCV4 for a while now with no problems.

 

On a recent flight to EHAM I received speed restrictions on the downwind leg of 230kts and 210kts on the base leg. I dont recall been given these before and thought it was an nice injection of realism.

 

However I dont know what i did different in planning or setup to get these restrictions and was wondering if anyone knew what the key to it was?

 

I ran the same route again recently and indeed got them again. Is this something that just appears at larger airports or is their a setting needed to get this every time??

 

Thanks for any help in advance.

Pattern speed restrictions have been in there all along. They might be lifted just a bit if you defined your aircraft as heavy.

 

The general button brings up a window titled aircraft and options. Type heavy grants in some places 250 knot speed relief on departure only as I recall and in some areas. The 230 knot arrival restrictions occurs shortly after the 30 nm inbound limit as you enter the airport traffic pattern downwind or less if on entering base or straight in.

 

The B747 and 748 is heavy as is I believe the 777. The B787 is called a super heavy, a new classification since RC 43 was released so just use heavy. Some others depend on the particular aircraft loading and configuration and can swing either way. You just have to define it yourself before the flight.

 

A tip:

 

On the Boeings with the Smiths FMC I place a range ring of 30 nm around the airport and start slowing to downwind speed. (I use 40 nm range ring for the crossing restriction.) On the Boeing FMCs go to the FIX page on the FMC. Enter the airport ICAO for the FIX ID. For the place bearing distance enter /40 or /30 or other radius for the range ring in nm and EXE the change.

 

I picked this up from watching cockpit DVDs on B763s and 737s. I do not know how to do this on other manufacturer FMC types.

Hi Ron,

 

Thanks for the reply.

 

I've checked all the settings in the RCv4 menus before and see no change as to what I normally

use. As far as I can tell the general menu never changes unless you deliberately change it for a particular flight, so not sure why i get any different instruction on this one route.

 

I always have aircraft set to jet in the 'plane data' box and not heavy.

 

Its a mystery.

Ehh....why would a 787 be classified as a super heavy when it's lighter than the 777 and 747. I'm guessing you meant the A380?

Hi, I thought the classification also depended on the likelihood of significant wake turbulence, eg 757. Perhaps that's what's going on with the 787?

Not really sure, but I thought wake turbulence classifications and ATC classifications were different. In the case of the 757, I think the wake turbulence classification is heavy, but as far as ATC is concerned, it isn't since the maximum take-off weight is below 300,000 pounds. I assumed we were talking about ATC rather than wake turbulence.

i'd have to see a log, to know why it's said in one place and not another for you.

Hi JD,

 

What do you mean by a log? One of my flight plans loaded into RC?

 

I can put something on here but I've checked and I'm sure their is no difference between that or any other route/settings i've used in pass for other routes.

 

Are those speed restrictions something I should get on most flights? If you are already below

those speeds do you not get given the restriction?

 

Cheers, Steve

Make sure you have lots of disk space. Get FS ready to go with your aircraft loaded and use a flight plan that illustrates your problem To keep the log length resonable try a 200 nm length plan that will take you on the same approach pattern as before, perhaps the same destination, time, weather, and arrival direction. Then open RC and click the debug button. Then load the plan into RC, make any selections, and start it.

 

Do your flight. If you get the same vectors and altitudes illustrating the situation, finish the flight until RC closes.

 

Go to your RCv4 or RCv4x folder. You'll see a file rcv4.log. Rename it to include the date inn the file name so it will not be overwritten on your next debug session. Use one of the freeware file compressors to squeeze it into a .zip format file. Maybe your version of windoes has it built in accessible by right clicking on the file name.

 

Attach it to an e-mail addressed as in the pinned topic subject the name of this thread and description of what you are looking for. jd will examine it and reply.

Hi Ronzie,

 

Thanks for the suggestion. I will give that a try when I get the chance.

 

Cheers, Steve.
