L1011-500 oscillating question
As you all know I am but just a flight attendant and DO NOT claim to know "diddly" about the functions of jet engines. I have been on one of our Lockheed 500 series planes for two trips in a row. I know the sounds and feel of our Lockheed's inside and out and I know when something is a miss. There is a feeling right after take off ( only on the second leg of the trip.. strange I know) it feels like the aircraft is shuddering. I called it a vibration. I question the first front end crew and tho they said they felt it they did nothing. The next crew was more helpful and discussed it in length. The 3 crew members affirmed my suspicions that there was a irregular feel. They called it an oscillation tho. There were no indicators in the cockpit at all. They have since "logged" it.. yet another F/a said the feeling is still there. Anyone care to speculate?

Almost certainly it's the Guvnor, committing an act of furtive self-abuse under a blanket as he listens to the thrilling sound of a real L1011,and dreams his dreams of Celtic Wings... <img src="wink.gif" border="0">

used to be called 'pod nod' by Gulf Air crews I think...as I remember and it was a longtime ago...oscillation under certain atmospheric/flight conditions in the engine nacelle which causes side to side oscillation of the pods which translates to the nose going up and down...dont ask me why/what etc. that's all I remember!

interesting replies folks! <img src="wink.gif" border="0"> Tcasclimb.. simply.. NO.
Iknowthat these babies are dinosaurs, but this only happens on the one aircraft! we have several 500's and this is the only one doing this!

Good to see the true principles of MCC (multi-crew co-operation) being applied. As we were told in our course, Locky, no-one is "just" an FA, they should all report anything they think might have safety implications!

Hiya All,
This thread may have solved a little riddle for me. Back in '86 I was SLF on a Cathay 1011 out of BK and I noticed a vibration through the early part of the climbout (say to 5000 ft or so). Never could work out what it was as it appeared not to be wheel/flap related. Never came across it again so just pondered on the matter ever since then. So, years on, PPRuNers have come to the rescue and solved something that has been bugging me. At last I can sleep at night!
