MD90
 

There´s a post in the ¨Questions¨ forum about SAS MD90 pitch oscillations. Seems to be a problem that has long been ignored. Anybody know why they don´t fix it?

Flathatter,

Are you suggesting that the pitch oscillation I asked about is not due to wave?
If not, surely this would not be a problem unique to SAS? I'm booked to fly on SK 524 to ESGG tomorrow so I would be interested to know. You seem to be suggesting that there is a lonstanding pitch oscillation problem with SAS MD90's.

I should add that I am not particularly bothered about it but am interested. I am more bothered about being left stranded again by SAS in ESGG,to discover how appalling SAS customer service is. :(

Just been in FRA with an MD90, as pax. Felt the same thing. VERY unpleasent. With 6000+ hours in the book I have never experienced an aircraft with these tendencies. Sell the darn thing anytime soon...

No cause for alarm. Apparently it´s only a couple of the 90´s that are affected. And apparently it´s just a matter of the autopilot and the trim switch not talking to each other properly. The porpoising can easily be remedied by disconnecting the a/p, make a slight trim adjustment manually, then reconnect the a/p. Problem is the boys up front don´t notice it nearly as much as the pax in the back. So should this happen to you again, ask a hostie to tell the skipper that you´re getting seasick back there and please trim the #$% &%$# plane.

Flathatter- the pax must tell the c/a to tell the skipper when to trim the plane, and this is no cause for alarm? Are the pax briefed on this? :)

How much does it move around then, and at what rate?

Enough to make my date airsick....not very impressing! Why not just install trim knops in each seat.....boy what funny landings we would have :D
