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?
