Hi

 

The Trimwheel does not turning after a Cold and Dark startup. The yoke I use for the aircraft has some trim switches!

 

The trimwheel works fine if i am turning with the mouse (point at the wheel and turn the scroll wheel of the mouse). What I am missing?

 

The trim switches work fine if not Cold and Darks (if starting directly!

 

Reply asasp, please//

You need electrical power to actuate the trim wheels with the control wheel trim switches. No power = manual trimming only.

Hi

 

I have understood it but it do not work. What do you need to know?

I can see that the Gen 1 buss off and Gen 2 buss off are lighting. I have saved a flight there the trim is working and the lights in that flight are off?

Gen buss light 'ON' means there is no power.. the light is on to draw your attension to it as there is a problem..  (no power)

 

When the  bus gen light is off, it means there is power, so the light goes out so it does not catch your attension ( as nothing is wrong)

 

I think the confusion is that you think  the light being on means there IS power, when there is not.

 

No power = no electrically operated trim switches work.

 

Hi

 

I saw it when I compared it!

 

The lights should goes out but way not, bellow can you se my steps for the elec startup, first bit:

1

Switch the DC bat power to on, close the Guard

 

2

In CDU --> Ground connection --> Ground power: Connected

 

3

Flipp the GRD PWR --> DN (on)

 

4

Flip the GEN 1 and GEN 2 --> DN (on) = GEN off bus lighting, it should go out!

 

The Airport is ESSA (Stockholm Arlanda )

 

I have miss something but what?

Gen 1 and Gen 2 ate driven by the engines. Attempting to connect the generators with engines off will not work. So the GEN BUS OFF lights remain on. However, you have AC power as you've connected external power.

Ok. But if I start the APU the trimwheel should work!?

 

It says that I would set the trim for takeoff before starting any engines but does it means manuell or with the elec trimswitch?

I have not start the aircraft any time before from Cold and Dark so the trimswitch mybe does not  work at al before the engines is started?

AC power from either the ground power unit or the APU should do the trick and allow you to use the electrical trim switches (provided the power source is connected to the electrical buses). If it doesn't, then it's likely that something else is not configured the way it should be. Some screenshots would be really helpful in determining what's going on.

No, you just need electrical power.Check the trim cut out switches on the centre pedestal. They could stop the trim moving. Make sure the control column is centred too. You can't move the stab trim in the opposite sense to the elevator.

<p> </p>

<p>After a check:</p>

<p>The switches have been messed up in fsuipc because of a unknown fault?</p>

<p>I can after resett it trim DN whenever I like but just trim up if I pull up the nose?!</p>

<p> </p>

<p>I think its allright with the settings but look anyway, I have check it just ned GRD power connected </p>

<p> </p>

<p>Thanks alot//</p>

It looks like you have the Standby Power and Bus Transfer switches in the off position, turn them on otherwise you won't have power to the electrical buses.  Make sure you have switched the Ground Power on - the light doesn't go out so make sure you LEFT click it.
