Most of the confusion you are having is between VFR and VMC and between IFR and IMC.

Under Visual Flight Rules, the pilot is responsible for separation from other traffic.  This is accomplished by requiring the pilot to be in Visual Meteorological Conditions at all times.  This means three miles visibility and specified clearance from clouds.  The cloud clearance requirements are to make sure that an IFR aircraft doesn't emerge from a cloud so close that the VFR aircraft can't see and avoid it in time.  Under VFR, the pilot need not be in contact with ATC unless nearing or inside control zones such as Class B, C, D airspace.  In dark night VFR, the pilot will be using the instruments heavily since there is no visible horizon to refer to.  At least in the US, a VFR pilot need not file a flight plan (in most cases) and can use any means of navigation, including reference to landmarks on the ground, VOR/NDB radio navigation aids, or GPS.

Under Instrument Flight Rules, the controller is responsible for separation from other traffic.  Because of this responsibility, under IFR, the pilot is always in contact with ATC.  This is true whether or not the flight is in VMC or IMC.  The controller will use radar or other techniques to keep track of separation and issue clearances to ensure that traffic remains separated and gets to where it is going.  When an IFR flight is in VMC, the pilot should be seeing and avoiding also.  The pilot will be on instruments in IMC, since there is no other way to keep the aircraft from an upset.  They may or may not be on instruments in VMC.  The pilot must file an IFR flight plan and be cleared for a route by ATC and may be re-cleared as conditions develop over the course of the flight.

A visual approach is not an Instrument Approach Procedure.  It can be given when the pilot is in VMC and reports the airport and the traffic they are following in sight.  The pilot will fly using visual cues from being cleared for the approach all the way to touchdown, but they are still under IFR.

On an instrument approach, the procedure itself is responsible for terrain avoidance above Minimum Descent Altitude/Decision Height.  If flown according to the charted approach with the appropriate altimeter setting, the aircraft is guaranteed obstacle clearance down to MDA/DH.  If flown with controller issued vectors, the controller remains responsible for terrain avoidance and will do this by using Minimum Vectoring Altitudes.    When you get to MDA/DH, you must have the "runway environment in sight" (one of a dozen or so things are acceptable) and from there you would complete the landing using visual cues, and once again you are still under IFR.  If you don't have the runway, or lose it before touchdown, you must initiate a missed approach and fly the published missed procedure until ATC issues a different clearance.

There are many little exception cases in what I've outlined.

I hope my English is understandable and please ask further questions if you want.

If possible, I encourage any ATC student to take a flight and experience these things from the pilot perspective.

Hello, i'm not native english speaker and i've studied ATC to be air traffic controller.

and i confuse the exact meaning between vfr and ifr.

i believe that vfr means Operation under only VMC and pilot must see and avoid any traffic or obstacle and ifr means Operation under only instrument and can operate in not olny VMC but also IMC.

but my thinks got confused when i study Visuall apprach.

Manual book says Visual approach is not IAP but still on IFR. but i think Visual Approach use the pilot's eye not instrument. so i think Visuall Approach is not IFR but VFR.

Does IFR mean that pilot only use instrument not visual? Is it VFR if pilot use he's eye to fly or land? Can IFR plane use pilot's eye? If VFR Pliot use navigation to fly, is it ifr not vfr?

and In the IAP, pilot must decide whether descend  or not at MDA/DH. Does it mean in the approach after MDA/DH, the pilot use their eye's not instrument? If it is yes, Is it VFR?

Thanks..

I created an Aviation Scanning Guide.
http://www.zipscanners.com/resources/aviation-scanner-guide/

I'm hoping this group can take a look and provide some feedback in the comments section of the article. 

Thanks!

Hello!
We are testing video live streaming from Locarno TWR.
Mixed airport with Civil and Military traffic, 3 parallel (short) runways with approximate 50000 movements per year. Civil and Military Flight school, gliders, parachute activity, helicopters (SAR base) and a friendly staff  grin
Follow us on out Facebook page for some news: www.facebook.com/lszltwr
And of course on live Atc Lszl TWR/gnd

Buy an Android tablet for under $200 - maybe a Nexus 7.  Download the "Avare" app - it's free.  Avare is just like Foreflight or the other iThing apps.  You can choose to download VFR and IRF charts, instrument approach procedures, airport information, weather, do flight planning, etc. etc. - and it is ALL free.  No monthly subscription, no download fees, nothing!  It's great - I've been using it for several years now, and they are continually adding features to improve it.  It does everything I need in the cockpit, and it's never cost me a dime.

And how or what program do you need to download? I did not want anything fancy and no contracts to sign just something basic scan someone help me out? What other programs are available?

One of the biggest challenges has been the loss of the automated flight plan system, which has forced the manual input of data into the system. Airlines are faxing flight plans and "everything from that point is then being done hand-written," said NATCA.

I wasn't looking for a list of destroyed equipment for “my Benefit” I was asking a more of a general equipment, were the radar feeds destroyed? Where the remote transmitters and/or microwaves destroyed, or the data system? Iit is geared to Center where the fie occurred.

Other centers will pick up the load.  This is planned for in advance.
I do not think a list of destroyed equipment will be published for your benefit.
Also, you need to distinguish Chicago Approach ("Class B") from Chicago Center where the fire happened.
