How do I turn off the Auto Climb Power reduction.

 

I have found the section in the options menu where you can set a default height after takeoff. But I would like to do it manually via FS2Crew i.e. "Set Climb Thrust". I thought it would only work with the VNAV armed, but it also works with VNAV off ?

That's something the automagic does for you per normal ops. Anything else would be non-standard, I think. In the real plane, to do it manually, you'd have to move the throttles on your own. FS2Crew does that?

This is a function of the FMC software revision - you cannot disable it. I wondered myself why FS2Crew tried to model the non-automatic procedures too... we don't have a non-automatic option.

 

Standard procedure with the FMC revision the NGX has is to arm VNAV before takeoff.

To my knowledge, Fs2Crew does not try to do anything to the N1 setting. The SOP modelled for Fs2Crew, is that PF calls "Climb thrust", as a verification call, when N1 is automatically changed to climb thrust. PNF confirmes with "Climb thrust Set". Next is Level change and then bug up speed/flpas up speed. Then clean up and move to VNAV. As I recall this the Fs2Crew modelled flow based on Boeing SOP. To be honest, I don't recall if Fs2Crew "models"/"is based on" to go directly to VNAV before cleaning up - that would be company specific SOP maybe?

Standart method to select CLB thrust after TO is to press N1 button. This dates back from the CLs, maybe even originals with Honeywell AP/AT system. Many airlines still do it that way to maintain commoniality, even if NGs would switch to CLB automatically (and possibly do, they just press the button anyway)

 

One of such instances was described by gentleman from Kulula we had on the forum last summer.

 

 

edit: At this point I feel it important to say, for the benefit of less seasoned users, that SOPs can, and indeed do, vary wildly between airlines, for various reasons, from traditionalism (we have done it that way on 200s), through, for a lack of better term, operational culture (famously, Southwest used to disable VNAV and ATS on their 737s for quite a time) or commoniality (we want to do it the same way for 737,747&757 all, if at all possible)

Thanks for your help guys, I didn't realise you could not turn the auto climb thrust off, obviously why I couldn't find it in the option section :Doh:

Check page 44 of the FS2Crew manual under 'Climb' you will see "Set Climb Thrust" for aircraft without auto climb reduction.

Hi Glenn - thx for the pointer.

 

But if auto climb reduction Off is not possible on the NGX, then I guess we would have to adhere to the method I mentioned...?

 

Anyways - I saw your post at Fs2Crew, so let's see if Byork can add something other than Damien... If the sofware is indeed modelled without the possibility to switch, I guess the Fs2Crew manualhas to be revised?

Hi Mas,

 

Ya the manuals need to be revised, that's something that slipped through the cracks as there was basically a "migration" of procedures from the iFly version which models/modeled different FMC software to PMDG, at that time there's was 10.7, PMDG is 10.8a. I was thinking of the iFly options, I knew i saw it in options somewhere.

Thx for the reply Damien... I think I read your explanation on the procedures regarding the climb thrust setting on auto, so I know that you at some point got both ways modelled - but that was probably for the Ifly I guess also...

so we HAVE to arm VNAV for T/O? I dont arm VNAV for T/O much, since alot of the DPS I fly are radar vectors and why would I want to exclerate to 250KIAS if Im going in the oppostie direction on a Vectors SID, I assume real NG pilots would do the same, I only ARM VNAV before T/O if the SID has Alt or Speed Restrictions or its strictly an RNAV SID with no vectors in it. That way I can control speed when I want and when I feel its approiate.

No problem, There is an option Without auto T/O thrust reduction and with FMC U10.8 but PMDG doesn't model it. I thought i had seen it in the PMDG options but maybe it was iFly.

You don't HAVE to do anything as long as you fly the aircraft safely. The v10.8a revision merely recommends arming VNAV prior to T/O. As for how you manipulate the automation, that's up to you. Since this is a sim you don't have any company SOP to follow. You could use FLCH speed control to keep your speed where you want it and then activate VNAV whenever you are on track to your destination. Or you could use VNAV. Or, you could keep the A/T disarmed altogether and control the throttles manually until you want to automate the thrust. None of those other options is recommended, but perfectly fine nonetheless.

Right, usually I dont select VNAV, I just the TOGA thrust and then get my FO to "Bug Up Speed" then when Im point in the right direction I hit VNAV and away I go. I have a Transiva video from JustPlanes and that is what they where doing.
