We have a procure at the facility I'm at now, that has been in question and it has come down from the "ALL POWERFUL" AOV as I stated above. They are the ones I want to do it like because they are the ones calling deals now.

I would never give a control instruction requiring a VFR aircraft to turn base at a certain point when wake-turbulence is involved. If traffic isn't a factor I will tell the pilot "turn base reference wake turbulence, report base."

your right, you can't tell him when to turn base. just to maintain visual separation for the wake turbulence. the second u for his base turn you owe him the full 3 minutes.

The visual separation is used in lieu of 3 minutes wake turbulence for a C172 touch and go (small, intersection departure) behind a C130 departure (large, full length departure). If you are not applying wake turbulence in this manner you are not doing it correctly.

Therefore, you need to provide wake turbulence separation.
ok i have been working hard and did get time to reply to all this but i would like to see what you think about this information. Note i added the **** but the capitalization is just as it is in the AIM.


AIM 7-3-6. Vortex Avoidance Procedures



a. Under certain conditions, airport traffic controllers apply procedures for separating IFR aircraft. If a pilot accepts a clearance to visually follow a preceding aircraft, the pilot accepts responsibility for separation and wake turbulence avoidance. ****The controllers will also provide to VFR aircraft, with whom they are in communication and which in the tower's opinion may be adversely affected by wake turbulence from a larger aircraft, the position, altitude and direction of flight of larger aircraft followed by the phrase "CAUTION - WAKE TURBULENCE." After issuing the caution for wake turbulence, the airport traffic controllers generally do not provide additional information to the following aircraft unless the airport traffic controllers know the following aircraft is overtaking the preceding aircraft. WHETHER OR NOT A WARNING OR INFORMATION HAS BEEN GIVEN, HOWEVER, THE PILOT IS EXPECTED TO ADJUST AIRCRAFT OPERATIONS AND FLIGHT PATH AS NECESSARY TO PRECLUDE SERIOUS WAKE ENCOUNTERS. When any doubt exists about maintaining safe separation distances between aircraft during approaches, pilots should ask the control tower for updates on separation distance and aircraft groundspeed.



7-3-8. Pilot Responsibility



c. Pilots are reminded that in operations conducted behind all aircraft, acceptance of instructions from ATC in the following situations is an acknowledgment that the pilot will ensure safe takeoff and landing intervals and accepts the responsibility for providing wake turbulence separation.

1. Traffic information.

2. Instructions to follow an aircraft; and

3. The acceptance of a visual approach clearance.

d. For operations conducted behind heavy aircraft, ATC will specify the word "heavy" when this information is known. Pilots of heavy aircraft should always use the word "heavy" in radio communications.



7-3-4. Vortex Behavior



Notwithstanding the foregoing, pilots are reminded that they should be alert at all times for possible wake vortex encounters when conducting approach and landing operations. The pilot has the ultimate responsibility for ensuring appropriate separations and positioning of the aircraft in the terminal area to avoid the wake turbulence created by a preceding aircraft.

*note i edited this one to cut down on the reading.

The AIM is not regulatory in nature, especially from a controllers stand-point.

Good info though.

I like it that the AIM and that wake turbulence reg support my point but I've never been a fan of using a pilot reg for arguing ATC procedures.

3-9-7 b:

b. The 3-minute interval is not required when:

1. A pilot has initiated a request to deviate from that interval unless the preceding departing aircraft is a heavy aircraft/B757.

NOTE-
A request for takeoff does not initiate a waiver request; the request for takeoff must be accomplished by a request to deviate from the 3-minute interval.

2. USA NOT APPLICABLE. The intersection is 500 feet or less from the departure point of the preceding aircraft and both aircraft are taking off in the same direction.

3. Successive touch-and-go and stop-and-go operations are conducted with a small aircraft following another small aircraft weighing more than 12,500 lbs. or a large aircraft in the pattern, or a small aircraft weighing more than 12,500 lbs. or a large aircraft departing the same runway, provided the pilot of the small aircraft is maintaining visual separation/spacing behind the preceding large aircraft. Issue a wake turbulence cautionary advisory and the position of the large aircraft.






How to Use English Punctuation Correctly - wikiHow



Know how to use the slash ( / ).

Use the slash to separate "and" and "or", when appropriate. The phrase "and/or" suggests that a series of options are not mutually exclusive.
"To register, you will need your driver's license and/or your birth certificate."
you can't stop reading at the slash. so as you see above the slash is and, or. therefore there are two ways to apply the section 3 above.



visual eperation



N12345 traffic C-130 departing runway 1

{N345 traffic insight}

N345 maintain visual separation, caution wake turbulence c-130 departing runway 1, runway 1 cleared touch and go.



/spacing behind the preceding large aircraft. Issue a wake turbulence cautionary advisory and the position of the large aircraft.




AIM

"CAUTION - WAKE TURBULENCE." After issuing the caution for wake turbulence, the airport traffic controllers generally do not provide additional information to the following aircraft unless the airport traffic controllers know the following aircraft is overtaking the preceding aircraft. WHETHER OR NOT A WARNING OR INFORMATION HAS BEEN GIVEN, HOWEVER, THE PILOT IS EXPECTED TO ADJUST AIRCRAFT OPERATIONS AND FLIGHT PATH AS NECESSARY TO PRECLUDE SERIOUS WAKE ENCOUNTERS.



N123 traffic is a c130 departing rwy 1. {N123 traffic in sight} N123 caution wake turbulence, c130 departing rwy 1 base turn your discrestion rwy 1 cleared for the option.

Does wake turbulence even exhist? I mean, it seems everyone has their own rules and they all seem to work. I suppose its just a matter of how to say it correctly.

it only exists if you misapply a rule and get an OE from it. if you never ever apply it and never get written up for it then does that mean it doesn't exist.

p.s. if a girl nags in the woods and there isn't a guy there to hear it...is he still wrong

It's maintain visual separation, caution wake turbulence, runway one, clear touch and go.
