That's a steep turn while holding your altitude +/- 100
feet.


If you meet your wake, you're descending.

I have sent the following question to an aerospace engineer at the
Rand corporation for his response...I'll keep you posted:
There is a thread on one of the aviation usenet groups that got me to
thinking...
In training, it it routinely common for a pilot to practice steeps
turns, and when you reach the roll out of a 360 degree turn with a
bank angle of 45-60 degrees, you will feel a hard bump, which most
instructors say is due to going through your own wake. One of the
commentators is arguing that this can't happen due to the fact that
wake turbulence descends. But it is a clearly easily demonstrated
effect. Is it our own wake? Or are we creating a vertical vortex
with the maneuver of a steep turn? (rather than the wake of wingtip
vortices). Is the data on wake turbulence behavior applicable to a
shrply turning aircraft?
