Some of our aircraft have it, some don't. I'm not worried, just curious. Our manuals doesn't tell us to do anything with it.

So, when you checked it, did you check the instrument, or could you check if the YD system was operating normally? Checking without knowing what you are checking seems rather pointless to me.

Respectfully.

What mechanism/ component moves the control yoke forward a fraction when flap is selected on the ground?
Look closely, when you go from clean to flap1/5/10 after engine start, the control yokes move forward a fraction.
( my guess is the elevator feel computer)

- movement in opposition to yaw checked both damper and instrument.

Are -700 and -800 flaps and slats interchangeable i.e. same P/N?

Was also part of Astraeus procedure a few years back.

I was told the B737 had a limitation on the maximum wind speed it could taxi in.

I was told it was 65kts. I could not find this in any of my company manuals nor the AFM.
The only place on the internet i have seen it written is on B737.org.

Is there any truth?

Have you got carbon or steel brakes or only a brake parachute?

if that was directed at my question then we use both Carbon and Steel brakes and some times hopes and dreams of stopping :E

As far as I recall, there are two figures for 737:

1) 40kts for Airstair operation
2) NOT a limit, but if taxied or 'open' parked in wind speeds (no, Rat, not Ryanair taxy speeds:D) exceeding 65kts, an engineering check is (?was?) required.

BOAC,
Thanks for the answer but where can i reference this? Its not mentioned in my company manuals nor AFM?

It's mentioned in my FCOM2, Chapter 1 "Doors and windows"

I once flew for an airline when hats were still in fashion. They had a temp'c limit when shirt sleeve oder was allowed. I asked about wind speed for the hated caps and was met with a dumfounded look.

TOM- Im not talking about the doors I'm talking about taxying!

Ive heard of Head, wind, tailing limits but never taxi.

I don't know where you will find it if it still exists. Ask your company? It is NOT a 'taxy' limit' - it is a wind speed above which a 737 ANYWHERE in the open needs (?used to need?) an engineering check. You could be sitting on stand;a/c parked overnight on the apron;taxying; whatever. Obviously headwinds as in 'flying' do not count. I assume it is to do with rudder maybe? Anyway, it isn't very likely to bother you.

BOAC!

We do not have this limit so this was probably a Company Procedure.

Could also be one that has been withdrawn? I'm sure the airstairs limit is still there. Ask Boeing?

That report regarding damage to a 738 rudder during a thunderstorm the previous evening makes interesting reading. Well handled by the crew but more significant damage could have really woken them up.
