I don't care what you you fly. I gave the reference, so read it.
7-3-9. Air Traffic Wake Turbulence Separations
a. Because of the possible effects of wake turbulence, controllers are required to apply no less than specified minimum separation for aircraft operating behind a heavy jet and, in certain instances, behind large nonheavy aircraft (i.e., B757 aircraft).
1. Separation is applied to aircraft operating directly behind a heavy/B757 jet at the same altitude or less than 1,000 feet below:
(a) Heavy jet behind heavy jet-4 miles.
(b) Large/heavy behind B757 - 4 miles.
(c) Small behind B757 - 5 miles.
(d) Small/large aircraft behind heavy jet - 5 miles.
2. Also, separation, measured at the time the preceding aircraft is over the landing threshold, is provided to small aircraft:
(a) Small aircraft landing behind heavy jet - 6 miles.
(b) Small aircraft landing behind B757 - 5 miles.
(c) Small aircraft landing behind large aircraft- 4 miles.

Pilot/Controller Glossary Term- Aircraft Classes.
3. Additionally, appropriate time or distance intervals are provided to departing aircraft:
(a) Two minutes or the appropriate 4 or 5 mile radar separation when takeoff behind a heavy/B757 jet will be:
(1) From the same threshold.
(2) On a crossing runway and projected flight paths will cross.
(3) From the threshold of a parallel runway when staggered ahead of that of the adjacent runway by less than 500 feet and when the runways are separated by less than 2,500 feet.
NOTE-
Controllers may not reduce or waive these intervals.
b. A 3-minute interval will be provided when a small aircraft will takeoff:
1. From an intersection on the same runway (same or opposite direction) behind a departing large aircraft,
2. In the opposite direction on the same runway behind a large aircraft takeoff or low/missed approach.
NOTE-
This 3-minute interval may be waived upon specific pilot request.
c. A 3-minute interval will be provided for all aircraft taking off when the operations are as described in subparagraph b1 and 2 above, the preceding aircraft is a heavy/B757 jet, and the operations are on either the same runway or parallel runways separated by less than 2,500 feet. Controllers may not reduce or waive this interval.
d. Pilots may request additional separation i.e., 2 minutes instead of 4 or 5 miles for wake turbulence avoidance. This request should be made as soon as practical on ground control and at least before taxiing onto the runway.
NOTE-
14 CFR Section 91.3(a) states: "The pilot-in-command of an aircraft is directly responsible for and is the final authority as to the operation of that aircraft."
e. Controllers may anticipate separation and need not withhold a takeoff clearance for an aircraft departing behind a large/heavy aircraft if there is reasonable assurance the required separation will exist when the departing aircraft starts takeoff roll.
