om... =20 The vortices generated by lift in the departing aircraft aren't the only form of wake turbulence. When I was based at a class B, I had numerous problems flying through the churned air generated by the engines of a departing jet (DC-9s and 727s were the worst). If spacing is tight behind a departing jet, it would not be unusual to experience some pitch and roll excursions in the flare. =20 John Galban=3D=3D=3D=3D=3DN4BQ (PA28-180) Heck, I used to get some exciting moments in my Cessna 120 on *taxiways* behind TWA Super Constellations.

Matt Whiting wrote: Bob Clough wrote: on the ground. Right? So does a landing aircraft really have to worry about wake turbulence from a departing aircraft? Only if you land past the point where the departing aircraft broke ground. But couldn't the turbulent air be blown back towards the beginning of the runway by a strong headwind, perhaps even beyond the threshold ? CV I suppose that is theoretically possible, but most airplanes large enoguh to cause serious wake turbulence probably don't lift off until 4,000 feet down the runway. With a wind strong enough to push that back to the approach end in any reasonable time, the turbulence from the wind woudl likely break up the vortices to the point where they wouldn't be a big factor. I never say never, but I think this is a very remote possibility. Matt |
