clearance up in the air. If you intend to takeoff VFR be sure to listen for your local Center frequency in the briefing. Radio coverage at the lower altitudes is poor. Wait until you are 1000' AGL or higher before contacting Center. At that time Center controller will give you a discrete transponder code and issue you your IFR. Remain clear of clouds until you have received your clearance. If weather is IFR (making it illegal to takeoff VFR), you must receive your clearance from Center through FSS while on the ground. Again, select the appropriate menu item. After you have received and understand your clearance, ready your aircraft, know what you are doing and what you need, then takeoff, calling Center leaving 1000' AGL. An IFR clearance through FSS, is similar to a normal clearance with an important distinction: your „Clearance Void Time‟. You will hear this important sequence sound like this: "Clearance void if not off by 2125. If not off by 2125, advise Center not later than 2130 of intentions". IMPORTANT NOTE – Many users have commented, “This is wrong. There is something wrong. I am being told „…if not off by if not off by”. They are right, but it is not wrong. Carefully re-read the sentence. Your void time will normally be 20 minutes from the time the clearance was issued, allowing more than enough time to get airborne and establish two-way. What is the purpose of the void time? When you are issued an IFR clearance and you hang up the phone, essentially you „own‟ that airport. ATC cannot clear anyone into or out of that airport until:
You are heard from and are well clear of the area
It is ½ hour past your void time, with pilot concurrence
It is 1 hour past since your void time
If the center does not hear from you by your void time, he notifies the Supervisors. If it has been ½ hour, he notifies the airport area's local Sheriff to check the ramp. If one hour has gone by without hearing from you, he calls SAR (Search and Rescue). Controllers look until they find you, and barring a disaster there will be a lot of questions.
Uncontrolled Field Arrivals
From your cruise altitude you will be given a step descent into the destination airport area eventually being issued the MVA (Minimum Vectoring Altitude). For example: „Dakota 34F, maintain two thousand two hundred, if able report the field in sight for a visual approach‟. Just as with Terminal Arrivals, you should request to leave the Center frequency to get the weather for your airport at approximately 50 miles from the airport. Just select the appropriate menu items.
Closing your IFR flight plan / Canceling IFR
If there is no Tower to confirm your safe landing, it is your responsibility to see that your IFR flight plan has been canceled. You are free to „Cancel IFR‟ while in the air (below the PCA) given VFR conditions. This is a common practice once landing is assured (and you have yet

good radio coverage), saving the trouble of another phone call to FSS telling them you have landed. The Menu Display includes the Cancel IFR menu item.

Flight Planning
Radar Contact supports many flight planners, some of which are freeware and some that are payware. The plans in this chapter will focus on two of the more widely used planners, FSNavigator and FSBuild. With the world‟s skies becoming increasingly crowded, having an accurate and efficient flight plan is not just a convenience, it is a necessity. By giving some thought to your flight plan, you will arrive at your destination with less time spent in the air, less fuel used, and more efficient handling by air traffic control. All flights operating under instrument flight rules (IFR) are required to have a flight plan on file with air traffic control. While controllers will assist a flight with vectors and information when able and where applicable, they are NOT there to hold your hand and walk you through every phase of flight. Their primary responsibility is to organize the flow of traffic and provide safe separation from other aircraft in their airspace. IMPORTANT NOTE - Pilots are fully responsible for knowing how to fly the route and procedures that they file. The same holds true with Radar Contact. As pilots, operating in simulated controlled airspace we must have an understanding of the procedures that we are planning and filing in order to fly competently within “the system”.
Navigation Aids
The first step towards ensuring that we plan a good route is to have some understanding of the equipment on the ground that we rely on for guidance. These are air navigation aids, or NAVAIDS. The most often used facilities are VOR, VOR/DME, VORTAC, and to a lesser extent NDB, for enroute navigation and ILS for approaches. With the advent of newer technologies over the last two decades, GPS/RNAV navigation is becoming the standard on the flight decks of modern airliners; however, VOR navigation is still widely used among general aviation and even older airliners, such as the 737-200 series.
