Am I wrong that a visual approach has to be within a certain intercept? Can someone get a visual approach from any direction without getting vectored? I guess I don't fully understand the difference.
1. Answer to both of those is yes(unless parallel runway ops are taking place)
Visual Approach
-Proceed visually and clear of clouds
-Must have airport or preceding aircraft in sight(if not you can still get the approach, but ATC will still be responsible for separation and wake turb. separation)
-ATC can initiate it
-Weather at the airport must be at least 1000 and 3(however the ATC handbook says 500 above the MVA/MIA)
-It is an IFR procedure conducted in VMC
-Cloud clearance requirements of 91.155 do not apply
-Weather reporting at the airport doesn’t have to be available if the controller has reasonable assurance that the weather is 1,000 and 3
-Only time they are required to give you a certain angle to final is when parallel runway operations are taking place and the runways are between 2,500 and 4,300 feet apart to prevent you from overshooting
Contact Approach
-Basically a visual but with lower weather minimums(basically scud running)
-Must remain clear of clouds, 1 mile flight visibility, and can reasonably expect to continue to the airport in those conditions
-The approach must be specially asked for by the pilot. Controller can not ask you to do one.
-Ground visibility at the airport must be 1 mile
-The airport must have an instrument approach procedure available
-You are responsible for obstruction clearance
-Because it is expected that you will climb and descend a bit to maintain obstruction or cloud clearances, you will more than likely be cleared for it at or below a certain altitude.
Only time I could see doing one is if you are getting vectored for a standard IAP and you can see the airport. Instead of getting vectored all over hells half acre, and the contact approach criteria is met, you can just ask for that and go right to the airport.
