Be careful about waiving wake turbulence delays at an airport like
this. There are some fine people that should still be with us but are
now six feet under because of this. Saving a few minutes is not worth
rolling upside down and dying in a fiery crash. Have you seen the
videos of visible wake vortices and how long they can persist?
Getting off early before the airliner's rotation point is one thing,
but unless you can outclimb it, you're still going to have to go
through the wake at some point if it hasn't dissipated.

Note that it is climb angle not rate that is important. Still best
to request a turn away from the heavier aircraft's flight path.

Also there are circumstances where they will not authorize waiving
the delays (intersections I believe).

In my years of running small planes out of IAD, I found it convenient
just to request to be sequenced behind some commuter turbo prop.
I'd rather depart behind a BE1900 than a 767.
