Flight controls check

[dr_anthony]

Checking today flight controls system 

Speed trim system works great.

Mistrim function on autoland works wonderful.

Autoslats system works cool.

Trim limit not implemented:

FCOM:

Trim Authority

Flaps Retracted - 2.8 – 12.5 units

Flaps Extended -  0.25 – 12.5 units

Autopilot Trim - 0.25 – 14.0 units

Manual Trim -  0 – 17.0 units.

On IXEG 737 trim wheel goes full travel disregarding on flap position.

Control column actuated stabilizer trim cutout switches not implemented:

FCOM:

Control column actuated stabilizer trim cutout switches stop operation of the
main electric and autopilot trim when the control column movement opposes
trim direction. When the STAB TRIM override switch, located on the control
stand, is positioned to OVERRIDE, electric trim can be used regardless of control
column position.

On IXEG 737 regardless of modelled  STAB TRIM override switch on pedestal and disregard of position of that switch moves control column opposes
trim direction NOT cutout the trim. Or i mistaken of that safety feature )).

 

All others flight controls features works great.

The  stab trim cut-out switches are working for me. Could you have another try and perhaps give some hints on how to reproduce if they are still not working for you?

Hi,

thanks for the thorough checking and feeback.

I don´t think we have implemented the limit of trim regarding flaps extended/retracted (I wasn´t even aware of that) - only the different trim speeds.

We decided to not implement the trim cutout with opposite control column as it is just too unintuitive in a desktop simulation and really only needed in a runaway situation.

BTW: You missed one error! When the autoslats deploy, there should be no amber "LE Devices in transit" light - only on the aft upper panel... Its listed in the issues list.

Cheers, Jan

HI, Jan, thanks for reply.

Yes, you are right, for desktop sim it not so critical.

And I really missed that error on autoslat system. 

Checked it again: on autoslat deploy green light extinguish at moment and then illuminated again.

On autoslat retract amber le flap transit illuminated, but it can't illuminated in flight.

Great work at all.

Nils, we are discussed control column actuated stab cutout switches, not control stand stab cutout switches - they are worked fine.
