Hi,When I am waiting the arrival of my RC 4, I read the table which compares the function of RC 2, 3, 4 in the RC 4 manual. I saw some of the functions that existed in RC 3 was taken out, namely, 1. Airport and navigation data from AIRAC cyclesDoes that mean RC 4 will not respond to any changes of navaids?2. Different transition lvls for departure/arrivalI actually see you can define trans LVL in the Controller Info page of RC 4 ,but the table said you can't? Oh... yes, so how do I set the trans Alt btw? 3. S-Turn vectors during peak departure/arrival demandOk... All AI will make way for you, so you don't need it anymore4. Random ATC issued go-aroundsOh... Wouldn't that be nice actually? Some levels of excitement at least...Thanks

1) all my nav info comes from the .pln file. if your planner has airac data in it, then that data will be part of the .pln that is loaded into rc2) transition altitude is specified but a table maintained in the data directory. you can change the transition altitude to more accurately represent the transition altitude at your airport. we only documented the major airports. what you can not set is the transition level, which is determined based on the barometric pressure and the transition altitude.3) correct4) seems to frustrated more people than were happy about it. it happens sometimes. sometimes i don't take control the ai fast enought, and they lolly-gag down the runway, while you're on finaljd

Hi there,2. It's the transition altitudes which vary from airport to airport outwith FAA airspace. We have a database for these but, if your chart says something different, you can change it on the controller info page.The Transition level is calculated from the transition altitude. It depends on the local pressure (QNH)All the best,John

1. Ok, so as long as I have the software which generates the pln files has the capability of updating AICAR, it'll be fine.....2. But from what I can see from page 27 and 28 of the manual, you are setting trans LVL instead of Alt (as the label shown, also you are entering 180 instead of 18000, which 180 is the representation of flight level)In addition, "The Transition level is calculated from the transition altitude. It depends on the local pressure", but e.g. here in AUS, most of the charts already defined trans Alt as 10000 and trans LVL as FL 110, it seems they don't care about local pressure setting....4. Different people have different preferencecs, so can you make it as an option just like what you have done for "holding" ? You can set if RC 4 will issue random instructions base on your setting...Thanks for the 2 prompt replies!!!

Hi,2. Well spotted - that's a screenshot from v3 :-(It looks a bit different in v4.Basically in FAA airspace their is no option and you cannot alter the setting from FL180.In non FAA airspace the TA is read from a data file and can be changed in the controllers options if you wish. If I've got the same copy as you p267 of the manual shows what to expect in non faa airspace.All the best,John

2. Oh... page 267, I haven't gone that far =) so you probably need to change the text in page 26 as well, quoted from manual :

"You may want to verify that the cruise altitude under the Center column is correct as well as verify or set your transition level (Trans Lev)."

I now see the trans level will be "advice by ATC".. so what will that be? I mean, once again, can I choose between "advice by ATC" and "User define"? in Aus most of the time will be FL 110.... if "advice by ATC", I'm not sure if I will get FL 110 everytime...

Hi there,p 107 and 108 of the manual (at least the version I have!) describe this.Essentially in Australia the TA will be read from a database according to the airport you are flying from/to. If you want to change it you can do so on the controllers page.RC calculates the appropriate TL based on the local atmospheric pressure. This will appear on advdisplay as RC is loading and also in the main RC window when it is running.As far as atc and the pilot is concerned there is a simple rule to apply.When atc assigns you to a flight level (such as FL120) the altimeter should be set to the standard value (1013.2 HPA/mb, 29.92 inches).When atc assigns you to an altitude (such as 12000 feet) the altimeter should be set to local pressure (QNH).Some sections in the manual and the last tutorial flight look at this in a bit more detail.All the best,John
