Wake Turbulence - What Does It Feel Like?

Yesterday I flew LHR-SFO on a BA 747 and I think we experienced wake turbulence, but not sure. We departed following another BA 747 and I made a mental note that I thought they were having us depart quicker than normal considering the 747 ahead of us. Usually there is a noticeable hold when following a widebody. As soon as we rotated and for the first 15 seconds of flight, the plane was jarred to and fro from side to side. I'm not going to say that it was a violent motion, but I did notice several passengers take notice. After a few seconds of this motion, the pilot banked us a bit to the left and it stopped. Was this wake turbulence?

Could be. Usually, when I've hit wake turbulence, it's at nearly right angles and it feels like driving over a speedbump going too fast. If you sat in it for a while it could feel as you described.

Sometimes when you are approaching or taking off too close to another airplane it can feel like you described.

I have also experienced wake turbulence during descent where I was preparing the cabin for landing and we abruptly (out of nowhere) turned to one side, violently enough to send me flying onto seated passengers. I've only had that happen one time where it knocked me off my feet - but through the years I've experienced it during cabin prep several times.

Please direct your attention to the flight attendants in the cabin...

Exactly. Quick and sharp. Quite different from "normal" turbulence, which typically is more like riding a boat over choppy seas.

Indeed! I experienced it once flying a late evening FR LGW-DUB and it was just like hitting a speedbump too fast as you say. Several passengers were sleeping and were awoken immediately by the sudden jolt. It only lasted half a second but it was interesting nonetheless. I did some asking around afterward and as soon as I said it felt like a speedbump everyone said wake turbulnce straight away!

Departure interval for a heavy following a heavy is 1 minute.

I've hit it twice, both times as the following aircraft on approach (i.e. parallel instead of perpendicular). The first was in a C172 following another C172, and the second was in a Citation following an A320. We got rocked from side to side, as if we were on a boat rolling in heavy sea swells (no pitching though). It wasn't sudden, but it was significant, and you had to work to overcome it, and then climb immediately to get above the last aircraft's flight path - I ended up continuing both approaches, flying a little higher than I otherwise would have.

Interesting - in the US it's two minutes.

I might have experienced something silimar on a KLM 738 departure from MAN. After we took off towards Stockport the plane began bouncing about, more than I have ever felt before, then we dropped and throttled up, bounced about even more, dropped again, throttled up and turned sharply left and then right. I have to say, this was the scariest take off I have ever experienced. I was surprised that there was no mention of this from the flight deck, as lots of the passengers were quite alarmed by it. Was this wake turbulence?

That sounds more like wind shear + turbulence but I'm not an expert. Was it stormy out?

Quick and sharp is exactly what we experienced, but laterally instead of vertically and it was consistent for the several seconds we experienced.

Ok re-read your post. It does indeed sound like wake turbulence.

I can't remember it being that stormy. I have never had a takeoff like it, where i was holding onto the arm rests and feeling pretty scared
