Boeing 737NG simulator seeking pilot...

[Intentional Left Bank]

Jastapilot, I think you may be referring to the speed trim system. It trims the aircraft automatically when the autopilot is not engaged to attempt to return the aircraft to the trimmed speed when the speed diverges from the trimmed speed.

Vol 2 says it operates most frequently during takeoffs, climbs, and go-arounds when: airspeed between 100 kias and mach 0.5, 10 sec after t/o, 5 sec following release of trim switches, a/p not engaged, and the aircraft senses a trim requirement.

I remember thinking and perhaps mumbling aloud WTF? the first time I noticed it trimming without the a/p engaged.

[Jastapilot]

Bingo. It's a great system for an inexperienced, or dozing pilot, but for a guy who is anticipating 3 moves ahead, it turns into a pissing match... and there's no use arguing with a computer. It's like arguing with Blastor.

Bonjour Alain,

J'ai regardé votre projet et je peux vous dire que vous êtes un génie. Je suis un pilote de Dash 8 Q 400 et j'aimerais beaucoup voir votre sim, est-ce possible ? Je suis de Québec aussi.

Bonne journée.

Quel bel avion que le Dash 8! Je le connais très peu me concentrant bien entendu sur le B737-800NG spécifiquement. Mais j'ai toujours été en admiration devant une telle beauté

Merci Skymaster pour tes bon mots...

Et bien sûr il sera possible de me rendre une visite. Envoies-moi simplement un PM avec tes coordonnées et disponibilités et je te contacterai... parles-moi aussi un peu plus de ton expérience etc...

Actuellement le simu est en ''...reconstruction'' car je suis à réinstaller certains modules comme les 2 FMC de même que les nouveaux throttle réels lesquels seront motorisés. Mais tout ça demande beaucoup de temps. Cependant j'espère qu'il sera redevenu fonctionnel d'ici une ou deux semaines... Du moins j'y fais mon possible!

Alors n'hésites pas à me laisser tes coordonnées et n'oublies pas que je suis toujours à la recherche d'un pilote qui a envie de partager ses connaissances et celà sur une base régulière.

Salutations,
Alain

Hello Jasta Pilot, RSW, Intentionnal LB, Tiny Voices, Jer, Fou1oh, Frog and all those who have followed this tread.
First of all I want to thank you for your help all time long for this foolish project. Every time I asked for infos, there was always someone to answer my questions, sometimes very basics...!
Without your help and support from each of you, I could not reach the level of realism which I aspired. This is why I tell you a very special thank today.
Finally I think the result is very close to the reality, but the futur will tell me I hope when one of you will come at home to do a flight with me...
Just to keep you informed, the throttle are installed in the cockpit since about three weeks and now are working with a good level of realism I hope.
Also I add functionnal radios that make the experience more close to the real thing again.
Unhappily my web site is not up to date as I need many time to make it updated while working on the sim. But as soon as possible I will take a couple of photos just to let you see the result here
Again, thank you very very much to each of you
Alain

[Jastapilot]

Should be great! Looking forward to it!

[alphatango]

Ssssssssssssssssssoooo!
Here it is! With Captain on board...
Photo taken today, so up to date... with 3 outside screens and new radios, but still incomplete!
Hope you like...
Alain

[Jastapilot]

WOW!

[alphatango]

.......
I will try to do some more today and post here...

Alain, where abouts do you live in Quebec? I don't feel like reading back that far and im not sure if you mentioned it. How far from YUL?

[alphatango]

I am 15 km east from Quebec city...

As promise and just for fun, here are 2 new photos.
For sure the pedestal is not complete but it is a good begining

Amazing!

[alphatango]

Despite the fact that there are still many improvements to bring to the simulator, this one is now fully functional.
So more and more often I have the opportunity to fly it and sometimes in real time on the net. This means that the flight is with air traffic control provided by real people using true techniques and frequencies. All this of course adds great complexity and realism to the flight ...
If you want to read a little story from a friend who just fly fairly regularly with me just go there... This is in french!

Hi all,
This is a long time I am not back here with interrogations...
But now I am back with many questions...
Daniel, witch is completing the overhead soft for the 737-800NG need some specific precisions... So here are those questions that maybe someone could answer.
1- The APU is running with both gens ''ON''. If I turn the battery switch on ''OFF'position, will the APU still continue running or will it stop?
2- If the APU stops, when I will restart the APU will the GENS be in the ''ON'' position or will I have to turn it ''ON'' manually again?
3- If I try to start the APU with the AFT1 fuel pump in the ''OFF'' position (cross feed closed) will the APU start?
4- Engines running and PACKS ''OFF''... If I push both throttle on maximum power, what will be the max PSI value?
5- In this situation if I turn both PACKS ''ON'' what will be this max PSI value? (or % of lost of power)
Once more many thanks for your help very much appreciated...

[alphatango]

Nothing yet???
I am very surprised! This is the first time... or this is too technical maybe? Maybe this is more maintainance questions...!

[Pajock]

I think I can only answer two of these.

1) The APU will shut down if you turn the battery switch off.
2) The APU will start with no fuel pumps on.
ok maybe three.

3) I believe the Gens will stay on-line after shutting the battery off with engine running.

As for the PSI stuff, no idea. The max is 9.1 though.

Hope that helps.

Hi Alpha
I know that if you turn off the battery switch with the APU running it will shut down immediately.

If the AC transfer buses were being powered by the generators at the time you shutdown the APU, they would remain that way and when you started the APU again it would simply start and be available to use but not connected to any buses until selected. If the AC transfer buses were being powered by the APU when you turned off the battery switch, if you are in the air there is a one time automatic function that will connect both generators to the AC Transfer buses preventing a loss of AC power. I am not sure if that same automatic function is available with the aircraft on the ground or if you would lose all AC power to the aircraft by shutting down the APU.

Any time you start the APU, it is just on and does not connect to the AC buses until you select it on buses.

Although it is good practice to run a fuel pump to help supply fuel to the APU, it does have a pump on it that will draw fuel for the APU.

If you are referring to duct pressure downstream of the packs with the thrust levers full open,and the packs 'off' my guess is zero and for your last question I don't know.....but I will try and find out for sure about question 4 and 5 and if I do I will let you know.

[alphatango]

Thank you to both of you Pajock and Bluetooth
Sorry for my late to be back...
Pajock, what do you mean by "ok maybe three." I do not understand.
Still waiting for the remaining questions... 4 and 5 if anyone can help.
Thank you
Alain

[Bluetooth]

I think he meant, OK maybe he could answer 3 questions...... At full thrust (brakes applied) with the packs turned off the duct pressure gage on the AC/press panel indicates between 40 and 50 PSI. I forgot what question 5 was so I'll have to get back to you on that.
