 If you request to deviate for wx, be sure to use “Wx on Course” when done to advise the controller. Likewise, if you have told the controller you would be a bit high/low from assigned altitude, use “Turbulence Gone” when you can again hold your altitude.
 Particularly on longer flights, you will transverse through any number of Centers and Sectors. Expect to be switched to these different centers/controllers from time to time. Some will require transponder code changes. Simply dial the new code in when it is assigned. If your co-pilot has the radios, he/she will do this for you.
At approximately 35 miles from BRIBE, things stop, the Flight Simulator freezes. Remember, we have enabled Pause at Distance on the General Options Tab. You are 140 flying miles from KORD. Consider this feature in your flight planning, especially those long cross countries or over-the-ocean flights where staying with the sim the entire way might be impractical. To continue, simply un-pause.

Time to Start Down
At approx 34 miles from BRIBE you will be told to “descend and maintain FL 270”. Descend and maintain is a statement, a "start down now" clearance. Notice the new option “3 – PD”. If you wish to stay at FL290 and be more fuel efficient, you can choose option 3. For now, acknowledge the descent clearance and start the descent to FL 270. When you near FL 270, the HIGH controller will descend you again to FL 240. When you near FL 240, the HIGH controller will switch you to the LOW controller for further descent clearances. You may be descended directly to FL240. Intermediate descents happen randomly. The LOW Center controller will issue a PD/"expect" clearance. For purposes of this tutorial, do not level. Continue your descent to the assigned PD altitude. Do not forget, descending through FL180, reset your altimeter to the local (Press B). About 17 miles from JVL you will have another sector switch. About 2 miles from JVL, the controller will issue "...cross four zero miles from 'ORD' at and maintain one one thousand, two five zero knots...” or "...cross four zero miles from 'ORD' at and maintain one two thousand, two five zero knots...”. Another new feature, RC now determines what runways are active at this point in the flight. If the active is a “near side” approach (no downwind) the controller needs you a little lower than if the active runway is a “far side” approach (downwind, base, final). Adjust your speed/rate of descent to meet this restriction accordingly. You do not have opportunity to “Unable” this clearance with Pilot Auto-Reply checked. IMPORTANT NOTE - The PD altitude and crossing restriction clearances have caused confusion to users since v1. Refer to your manual, the sections Pilot Discretion Descent Clearances and Crossing Restrictions for in-depth explanations.
As you pass BULLZ, get the arrival ATIS at approx 50 miles out by using “Lv Freq for Wx” (Press 2). You will make the request to leave frequency, hear the ATIS loop, and report "back up" all automatically. And what runway did ATIS say to expect? Listen!
If you wish (stay ahead of things), use the ILS information displayed on the Menu Display, below the checkpoint data. This information become available after you report “back up”. You will see something like <14L>142°/11090. Set the ILS frequency and course data in your #1 radio now, and 113.90 in Nav2 (ORD VOR frequency).

O’Hare Approach
At 40 miles from KORD, Center will switch you to Approach. We will accept whatever runway Approach needs us on. You have not received any alternate clearances yet, so continue towards your final checkpoint, ORD. Follow the clearances issued by Approach.
While being vectored, take a moment to look through the menu pages and become acquainted with RC‟s enhancements. All are covered in later tutorials. For this flight however, as tempting as those features are, let‟s follow the Approach instructions to landing. Do not forget to reset that altimeter from time to time. Get after those checklists! Remember: never exceed 250kts while below 10,000. There will be an initial heading/altitude clearance that sets you up for pattern entry and eventually you will be turned to downwind and base. Larger, busy airports have multiple Approach controllers. KORD certainly qualifies. Contact the Final controller when told to do so. ATIS named rwy 14L as active at this tutorial‟s writing, calling for full pattern vectors. Your approach sequence may be different. Simply follow your clearances. At the appropriate time you will be turned towards the localizer with "American 293, XX miles from the marker, fly heading XXX°, maintain 4500 until established on the localizer, cleared ILS rwy XX approach". Begin the turn, intercept the localizer and continue descent below 4500 as the glide slope indicates. Keep the needles centered. Watch your speed. Do not exceed 230 knots on downwind, and 210 knots on final
