I have flown the cockpit jump seat on MD
-80's a few times. On take off I could feel and hear the NLG retract into the wheel well. It makes a the nose of the aircraft shudder a little but not enough to bother the pax in 1st class. The nose wheel spin brakes stop the tires spinning within a few seconds if they not to worn out. I have had pireps about this. I have flown in 1st class a few times on MD
-80's also and I never felt a shudder from the nose gear coming up.
The fuselage extends quite a bit foreward from the wings and I think that makes it more susceptable to vibrations. I think an MD
-80 pilot would be alot more helpful on this topic. I'm basing my opinion from a MX
tech stand point.
Is it broke...? Yeah I'll fix it.
