Imagine you're holding short of Runway 9 in your Cirrus SR22 when Tower clears a Boeing 747 ("Heavy") for takeoff on Runway 27. You call Tower for a takeoff clearance as the Boeing levitates from the runway, producing unseen vortices amid the waves of hot, spent kerosene. Tower tells you to expect a three-minute delay for wake turbulence. If you ask to waive the delay (perhaps not a smart choice), is ATC permitted to approve your request to deviate from the required wake-turbulence delay? Note: The Cirrus is considered a small aircraft.






No, unless the winds are calm


Yes, provided the wind does not keep the vortices over the runway
