pretend that KDSM is a small and empty airfield, simply uncheck the checkboxes of the services that you want to get rid of. If you clear everything, you will always have FSS, which is the Flight Service Station, where you can file your plan (on the ground or in the air) and which will give you the latest weather. The reverse is true as well. If you would like to pretend that the small grass strip behind the highway is a major international airport, simply check the boxes of the services you want, and RC will load the frequencies for you. If for any reason, you do not like the frequency, you can change it within the range 118.00 to 135.00.
Runways
Below the frequencies, you will find two drop-down boxes with the runways available to you at the departure and destination airports. If you want RC to assign you a certain runway for taking off and landing, choose it here. Otherwise, RC assigns the runway that is most suitable given the wind conditions and AI traffic patterns.
NOTAMs
Check these where appropriate for your departure, arrival, alternate 1, and 2 airfields. Check this whenever you takeoff or land in hilly or mountainous surroundings. Normally, RC gives you clearance for certain altitudes during departure or approach. When you fly in the Swiss Alps or in the Rockies or near Mount Everest, it is quite possible that RC will vector you straight into the side of a mountain. However, if you have thought about it, done some reconnaissance, and checked these NOTAM boxes, RC would in effect leave you free to pick your own altitude. When filing a NOTAM on departure, RC expects you to tell the controller when you are on course and able to follow his altitude instructions. Only then will it be possible for you to hand over the plane to your co-pilot. If you have filed a NOTAM during approach, your co-pilot will hand back the plane when you contact approach. After all, the whole purpose of the NOTAM is that RC does not know the altitude of the terrain you are flying over, so the co-pilot does not know it either. We have already discussed the requirement to tell Departure (or Center) you can proceed on course. Further, assume your arrival airport is a NOTAM field. If you miss approach and elect to fly to one of your alternates, Departure (or Center if no Dept controller) will ask you to advise when you can proceed on course as you are leaving the area.
Gates
Underneath the NOTAM field, you come across textboxes where you can write the gates that you want RC to assign for departure and arrival. If you happen to know that your flight KDSM-KORD always leaves from gate G4 and shuts down at gate 25, it is somewhat neat to put these figures in there.
Transition Altitude
For airports in North America, no user input is required in this section as the default Transition Altitude of 18,000ft is used.

For airports not covered by FAA regulations, a user-editable text box will appear which allows the appropriate Transition Altitude to be entered. Radar Contact is supplied with a database of real-world Transition Altitudes for many of the world‟s major airports and if the airport is in the database, RC will enter the correct Transition Altitude in the text box. If there is no entry for the airport in the database, the default altitude of 18,000ft will be used but you can edit this if you wish. Transition Altitudes can be found on many SID, STAR, and instrument approach charts. IMPORTANT NOTE – RC needs Transition Altitudes to be input in the ICAO standard format of whole thousands of feet. A small number of airports have non-standard Transition Altitudes which should always be rounded-up to the nearest whole thousand. For example, if an airport has a published Transition Altitude of 6,500ft, it should be entered as 7,000ft. In North America, the Transition Altitude is the point below which RC will control your vertical position by reference to altitude (thousands of feet); in other parts of the world, it is the point at and below which your vertical position will be controlled by reference to altitude. When flying at or below the Transition Altitude (below the Transition Altitude in North America), your altimeter subscale should be set to the local pressure (QNH). When you start RC, the program will apply the local pressure setting (QNH) to the Transition Altitude to calculate the lowest available flight level.
Transition Level
No user input is allowed in this section because the Transition Level is calculated automatically when RC is started. Both the departure and arrival Transition Levels are shown briefly on the Menu Display display at start-up and they can be seen in the Controller/Flight Options section on the main Radar Contact page. IMPORTANT NOTE – A small number of countries have fixed Transition Levels rather than calculated ones – this is not simulated in this version of RC and all Transition Levels will be calculated at runtime. For flights outside North America, the Transition Level is the lowest usable flight level above the Transition Altitude. The definition of “usable” varies from country to country so for consistency in RC, we have defined it as the flight level that gives at least 1,000ft separation above aircraft flying at the Transition Altitude. The Transition Level is the point at and above which RC will control your vertical position by reference to flight level. When flying at or above the Transition Level, your altimeter must be set to the standard pressure setting of 1013.2 hPa or 29.92 in/hg. When climbing or descending, your RC co-pilot will remind you of the need to reset your altimeter from local pressure (QNH) to standard pressure and vice versa with the phrase “altimeter check” at the appropriate time.
