Radar Contact 4 altitude problem

Recommended Posts

Guest erwin969

I fly from Cologne to Amsterdam with a Learjet 45. Everything going smoothly. But when I must decent from ATC to 16.000 ft I have some problems, ATC says: watch your altitude, your altitude is 16.000. But I was already on 16.000 ft. ATC repeat it 4 times, than I must switch to Amsterdam Radar. I must decent to 12.000 ft, but also Amsterdam radar repeat 4 times: watch your altitude etc. But I was on 12.000 ft already. What's that? I have this problem for the second time in a row now. But I don't no what it is. Please, someone have an answer for me?

Hello,Are you sure you weren't told to "descend to Flight Level one six zero" rather than "sixteen thousand feet"?In Europe the Transition Altitude is much lower than in the US and varies from country to country. I suspect you have been using FS ATC where 18000ft is used worldwide.I suggest you read the manusl on Transition Altitudes and Flight levels because it sounds like you were at 16000ft when you should have been at FL160.It's all down to the pressure setting on the altimeter. In short, when ATC clear you to a Flight Level (FL160) you should set the altimeter to standard pressure - 29.92" / 1013Mb.When you're directed to a altitude - 4000ft - you should switch to QNH.Hope that helps.

No, ATC said to me 16.000 feet, not 160.000 ft. B.t.w. I had no problem any before. I thought is a bug. So saterday I fly from Rotterdam to London Luton with the learjet 45, also the same problems.Maybe it is a scenery issue? I installed 2 new scenery's for airports. Maybe, press first 'Rebuild Scenery db' in Radar Contact 4?

No, ATC said to me 16.000 feet, not 160.000 ft.That doesn't make sense. There's no difference.Run the scenery rebuild as you have added new scenery. Can you attach a flight plan so I can load it into RC4. I haven't flown v4 for a while and need to refresh my memory.The TA in Holland is 3000ft and at Luton either 5000 or 6000ft so you should never hear "16000ft".

Our messages are crossing. Load your plan (or the one I supplied) into RC4 and open the Controller Info page. It should resemble my screenshot. Pay attention to the TA for both airports. Change your Cruise to FL290.I cannot see how you would not be cleared down to Flight Level 160 rather than 16 thousand feet.Let me know how you get on.

I make a new plan with FS nav. And the flight was going smoothly. I keep attention on my altimeter, press manytimes the B button to have the correct altimeter setting and I have update the scenery db in RC4. Maybe that was the problem also.

the "B" key doesn't work in non USA areas. there are several items in the manual about non-USA areas, the "B" key, and tranistion alitudes and transition levels.jd

Hi,I keep attention on my altimeter, press manytimes the B button to have the correct altimeter setting and I have update the scenery db in RC4. Maybe that was the problem also.The problem is caused by pressing the B button to reset the altimeter. That only works correctly in FAA airspace (USA). When outside that airspace such as Europe you must not use that key to reset the altimeter pressure.Instead, adjust the pressure on the gauge of your aircraft. If that is not possible and you have a registered version of FSUIPC you can assign buttons to Kohllsman Incr and Kohllsman Dec which will allow you to increment and decrement pressure. There is also a Kohllsman reset which will reset pressure to 1013.2 / 29.92.The scenery rebuild is irrelevant for this problem but you should always run it after installing new scenery.And are you now being told to "descend to flight level one six zero"?Cheers,

No, I'm not being told to decent to level one six zere, from 29000 to 28000 than to 24000, 19000 and then 11000 etc. So strange that I'm now not have any problem with the decending etc.

Hmmm. Ignoring FL160 are you saying that during descent you never hear "descend to flight level two four zero" but instead hear "descend to twenty four thousand feet"?That still doesn't make sense. What value are you entering in the Cruise box? Is it 290 or are you entering 29000?I appreciate you may have resolved the problem with not being at the correct altitude but you should be cleared down through various flight levels and not altitudes in feet. That should only occur when you're cleared below the Transition Altitude.Cheers,

But I never reach 32000, ATC gives me a clearing for 290, quick after that they give a clearing to decent for 280, 24, 19 etc.

Hi,I don't know what they saying, but I think "descend to flight level two four zero"If you're hearing that instruction then everything is okay. There is a big difference between FL240 and 24,000ft. :-)The value in the cruisbox was 32000 ft because FS Nav give this.If you look carefully at the cruise level box you will see two zeroes just to the right. That means that you should only enter 290 in that box and RC will interprete it as FL290. If you enter 29000 it is interpreted as 2900000 feet or over 500 miles (1000 kilometers)!! :-eek Clearly you can't reach that cruise altitude before RC needs to start you down but all the commands are to a flight level which is correct.Spend some time reading the manual on Transition Altitudes and Flight Levels. This Wiki article is also useful. http://en.wikipedia.org/wiki/Flight_levelCheers,

>No, ATC said to me 16.000 feet, not 160.000 ft. You're clearly not understanding what is meant by "flight level". FL160 is not 160,000 feet, it relates to an altimeter setting in hundreds of feet but only when the altimeter is set to the standard pressure of 29.91 ins or 1013 mB. When you are above the transition altitude for your area (in Europe anything from 3000 to 10000 feet) you set your altimeter to that standard pressure and when told to "climb to FL230" or whatever, you enter 23000 into your autopilot and when you get there your altimeter will read 23000 feet. But you will most likely not be at 23000 feet. You could be several hundred feet either side depending on the atmospheric pressure where you are.This is done so that all aircraft above the transition altitude are reading the same thing on their altimeters and are climbing/descending by the same amounts.Read the manual as Ray says. It is very important that you understand this.

Just had another thought on this and something else to check. If, when flying in Europe, you really are hearing controllers say "16,000 feet" are you hearing the default FS ATC controllers? Have you turned off the default FS ATC voices? If not you will still hear them as, even with Radar Contact installed, FS ATC keeps on working in the background.Just remember, when flying in Europe a Radar Contact controller will never say "16,000 feet" but "flight level 160". They will only say 16,000 feet in North America and a few other areas where the transition altitude is 18,000 feet. However, the default FS ATC works to a transition altitude of 18,000 feet everywhere.

"16,000 feet" or "flight level 160".Hi Can you please tell me what is the difference between these two.Many thanks.Qas

Qas,It's covered in the manual. Alternatively read the Wikipedia link I provided earlier in this discussion.Cheers,

Thanks for the reply RayI understand the basic of this-I think.What I am confused about is what are the different actions I need to take if the RC4 controller tells me either of these-I also get the 'busted altitude' threats some time even though I am flying at the required altitude.I always ask for weather update if this happens and adjust the pressure as appropriate.Qas

it's in the manualif you are told fl160, then the altimeter has to be on standard pressureif you are told 16000, then the altimeter has to be on the local pressurepressing the "B" key does not work, outside the united statesjd
