One question here about trim wheel...
How much turns are needed to go from trim full up to full down... I mean, if the trim wheel for an exemple is adjusted full down how many turns of that wheel will I need to adjust that trim to full up?
I need this information to make my gear trim at the right specifications... I already know that when flaps down the trim wheel turns at around 4 revolutions per second while in a flaps up position it is around 1 turn per second. If I am wrong please tell me before it is too late
Thank you,
Alain

Hey ALpha Tango,

looked that up for you as best I could find, there are 2 regimes... high speed and low speed like you said as per the flaps up switch, but it is broken into autopilot on and auto pilot off.

with no autopilot on and flaps up- speed is .2 units/sec
with no autopilot on and flaps down- speed is .4 units/sec


with autopilot on and flaps up- speed is .09 units/sec
with autopilot on and flaps down- speed is .27 units/sec

As that relates to revolutions of the trim wheel itself (units per revolution) I am not sure.



Also, remember that flaps up or down changes the electric trim autority...

on the -700 main electric trim flap down - 0.05-14.5 units
flaps up - 4.3-14.5 units

this is why you need to electric trim nose down to the flaps up limit, then select both main stab and autopilot stab trim switches to cut out, and then continue manual trim with the handle to the foward limit for deice. (don't for get to put the handle back in and select normal again!!)

That is not to say that as the flaps are coming up you can't take advantage of the greater nose down range (0.05) and electric trim nearly all the way forward, but where I work they don't like that.

hope this helps. cheers,
RSW

Rightseatwonder,
So there are not only two but 3 differents speeds. In the goal of making it a little easier I will use tw0 speeds only. I will use 3,5RPS when flaps down (compromise between 4 and 2,7) and 1,5 RPS when flaps up (compromise between ,9 and 2). I think this will be a good use of that trim wheel.
But I do not understand what is the total range of the this trim wheel. To make it easier for me to undestand could you tell me how many turns from full up to full down (let say flaps down) this wheel will turn?
Thanks for your help that is very helpfull for someone who cannot get into a real cockpit in flight...

[rightseatwonder]

there is actually 4

1. autopilot on flaps up
2. autopilot on flaps down
3. autopilot off flaps up
4. autopilot off flaps down

i don't blame you for simplifying it....

as for how many rotations of the wheel actually occur... next time I work i'll check it out...full range.

but it is different again depending on flaps up or down.. ie. the range is shortened ... less nose down electrim trim range with flaps up..(see last post) I am assuming this is protection ranges for flaps up manuvering.

I'll try and check how many spins the wheel will do for total full nose up to full nose down trim....and let you set the forward electric limit. man my arm is gonna be tired!! lol


cheers,
rsw

Hi RSW,
Thank you for your quick answer!
yes I understood the difference between flaps up or down and A/P on or off... The explicaion was very clear, even if I do not speack english very well
When you will check (lucky man you are!) the number of trim wheel turns please check it with flaps down... the wider range!
This is very kind you do that...
Thanks so much,
Al

[rightseatwonder]

OK Al here goes...

...I rolled the hell outta the trim wheel... manually.... ouch... and heres what I got.

it takes approximately 80 revolutions of the trim wheel to move the indicator 5 trim units.

thats approx. 16 revs/unit

so the full indicated range of the trim is approx 17 units... therefore 17 units X 16revs/unit = 272 revs for full indicated range.

from the previous posts and your own research i'm sure.. with some simple math you should be able to calibrate the trim motors to different speeds (for all 4 regimes) with this gearing and be set up nicely.

hope this helps,

RSW

[alphatango]

Hi RSW
This is exactly and precily what I needed...
Just hope you did not break your arm doing this... A lot of turnsssss!
Thank you so much... I'll do my best to simulate the exact situation
Al

[rightseatwonder]

good luck.. looks like a LOT of work went into your sim.m

cheers

I need some infos about TO/GA buttons on throttles!
What is the real procedure for it?
When I want to use these buttons on the throttle,
- first I deternine the N1 setting in the FMC in N1 limit page...
- then when ready for take off I active the MCP N1 button, then push throttle handles up to approx 2/3 and push the TO/GA buttons on the throttle.
In my mind it should activate the throttle handles to the N1 setting enterred in the N1 limit of the FMC...
Is it the right way to make a TO/GA take off?
I suppose that "TO" on the left of the FMC "N1 limit" page this is for Takeoff, and "CLB" is for climb!
I hope my question is not stupid and that you undertand my question!!!!!
Thank you for your help,
As you may see, I am still looking for a real 737 pilot...!

you're bang on with the to/ga button on takeoff, just like you said. The A/T's will advance the thrust levers until the N1 is at the green carat(the thrust setting for t/o) The FMC's are as follows. The pilot flying has the takeoff speeds page on his side, and the PNF has the Legs page up. Hope that's what you're looking for.

[alphatango]

Thank you Four1oh ,
Tonight I am planning a flight... I will try it to see if everything is working properly on the sim...
I will follow the right practice, CPT side FMC at takeoff speed page and FO on leggs...
Then no need to activate manually the N1 button on the MCP? Just the A/T on! I imagine that N1 button will light up once TOGA activated on throttle?
Regards,
Alain

[Four1oh]

With the autothrottle armed for takeoff, once you hit the to/ga button, the proper modes activate automatically.

PS: we even let the FO's fly once in a while... so make sure it works from both sides! That why I said Pilot flying and Pilot not flying!

3 new questions for you...
We are working on the "windows heat system" simulation located on the Overhead. And the goal is to make it as real as possible...
So, when these 4 switches are "ON" each annunciator lights up when the heating system is working. So i suppose that when the windows temp reaches the good temperature (20degrees I think) the heating system turn "off" until the temp cools down and the heating turns "on" again..
- Am I right to think it?
- If yes, when the heating system turns off , does the annunciators tunr off also (individually) or do they remain lighted to indicate that the system is engaged?
- If yes, in cruising altitude (let say FL350) in winter time will these annunciators turn off for a long periode of time like 2 or 3 minutes or for a few seconds only?
Thank you again for your support...

[Four1oh]

When you first turn them on, you get a green light for each window heat. You are right about getting to temp, they will then cycle on and off, and when they do that the light just goes out. Green on, no light on but cycling. If there's a fault you get the amber light. I'm almost positive(I'll check tommorow) that the switch in the off position gives an amber light.

I don't think you'd see the windows cycle in cruise as the OAT is in the -50's to -70's with a windchill in the thousands. But it is normal to see it cycle on the ground. Usually what you'd see is only 1 off at a time, for only a couple minutes. I suppose while flying in warm air it would cycle too.

Thank you for these infos,
I am waiting to have your answer about "the switch in the off position gives an amber light".
...If you need someone to take your place up there lucky man, it will be an incredible pleasure for me to do that for you for one day...
I have simply not been perseverant enough when many years ago I was bush pilot and still young...

[Four1oh]

crap, I forgot! I'll do ya one better...

1 Window OVERHEAT Lights
Illuminated (amber) – overheat condition is detected.
Note: OVERHEAT lights also illuminate if electrical power to window(s) is
interrupted.

2 Window Heat ON Lights
Illuminated (green) – window heat is being applied to selected window(s).
Extinguished –
• switch is OFF, or
• an overheat is detected, or
• a system failure has occurred
• system is at correct temperature.

3 WINDOW HEAT Switches
ON – window heat is applied to selected window(s).
OFF – window heat not in use.

Hi,
A new question here...
It is about the six packs...
When an annonciator lights up on the six pack. Let say that we have a malfunction on a fuel pump... Then the sixpack "fuel" lights up and the yellow warning light just beside lights up also... When you push on this warning toggle does it turn the "fuel" light off? Or do this "fuel" light remains "on" until you solve the problem? I think it goes off but am not sure....
Thank you for your help,
AT

[Jastapilot]

Whenever you press the square Master Caution light. It will clear the Master caution light AND the light from the six pack, which is why it is very important to IDENTIFY the problem before you cancel the light. The light associated with the fault will remain illuminated until the problem is solved. Also, every time you Recall, meaning, you press the six pack, it will re-illuminate any faults by resetting and rearming the Master Caution system. So if you cleared the Master Caution and the fault still exists, when you press the six pack, you'll get a Master Caution light with the associated six pack light.
In your example, let's say it was a center fuel pump low pressure light, when you switch the pump switch off, the light will extinguish.

Hope that wasn't too confusing.

You realize by the looks of things that when the YQB port gets going the lucky buggers will be able to do all their sim training at home?

Hi Guys !

I'm not a 737 pilot, but I went this week-end to try it and made a short flight from Quebec to Montreal and flew it. Well, if you guys that knows the 737 and you get a chance to see it, it is worth the tour. After I went, I watch the WestJet DVD to take a closer look at the cockpit and I am amazed to see how someone that has never flew a real one can built something like that with that much details. Even looking at the DVD, I could recognize the very same things I saw in the simulator. The guy is very friendly, he is a passionate ... and he is looking forward for your visit to learn new things on his own simulator. I couldn't teach him lots with my Beech and Pilatus experience and he really appreciate it, so imagine what you could do to help him.

Looking forward for my next sim session ! Thanks AT !

Four1oh,
I forgot to thank you last time... sorry for my mistake...! BTW it has been very helpful!
What Daniel did is to simulate the windows heat by calculating the exterior temp and the wind and then the annunciators goes off when the goal temp is reach (20 celcius). Then on the ground it often turns off. But in the air never in the winter time at FL380 and at cruise speed!

Jastapilot,
It is very clear, not confusing at all, despite of my poor english. It confims what I had in head. Then we will simulate this way...
With your help from you all we should manage to simulate something quite close to reality

Jerome...!
What a great appreciation from a nice guy... I'll keep it in my best comments for a while. I appreciated a lot your visit and I was very proud to show you my last 5 years works. Just hoping your visit again. Who knows? Maybe somday will you need some 737NG practice?????
Thanks for all Je,
Friendly,
AT

[Four1oh]

I'm glad i could help you out! It was my pleasure! If I ever get one of those YQB overnights with a decent layover, I'll come by an buy you a beer. Cheers!

Hi all,
In my quest to make the sim as real as possible I am working on real737-200 throttle to replace those I built some years ago! Actually at the stage of finalising those throttle I am wondering what is the role of the right side lamp (stab trim light)...
If you know how it is working and what it does I would appreciate...
Thank you,
Al
