    What is "Autopilot Beta" ?

    Hi,

    In the MCP meny there is an option "Autopilot Beta".

    In PM manual I do not see any info on that field.

    Does anyone know what it is ?

    Thanks,

    I think it has something to do with a new autopilot they are testing. Try using it and see if it's better than the current one. It can be turned on and off as you please.

    Re: What is "Autopilot Beta" ?

    I donīt know if you noticed , but using PM , when you takeoff and at 400ī engage the AP , the N1 engages automatically . So , when you get to 1000ī and thatīs the time to really engage N1 and Set speed to BUG UP to accelerate acft , N1 is already on . If you forget and press N1 , the AP desingages. This is not correct, in the real acft at 1000ī you press N1 and BUG UP and start to raise flaps on schedule. I donīt know if this has something to do with FS . By what I have heard , Enrico is trying to fix this with "autopilot Beta" . I donīt know if it is true.

  5. Thanks Nick1150 thanked for this post

    I forwarded my question to PM, and the response I had was NOT to use "autopilot beta".

    So I guest it is a test autopilot feature

    Re: What is "Autopilot Beta" ?

    Sorry Leilson but what you sayd isn't correct.

    In the real aircraft after you press TO/GA the FMC command a N1 take off thrust. At 84 Kts change to THR HLD until at 800 RA. As you can see on FMA.
    after 800 RA change from THR HLD to ARM to make reduction to Climb Thrust pressing the N1 Button. (In the NG the thrust reductions is make automatically as setted on the CDU. )
    The Thrust reduction to Climb Mode is not the same to all Company. Anyone have his policy. It depends also if you need a NOise abatement Procedure.

    The automatic thrust reductions to Climb Power occurs when VNAV, ALT ACQ or ALT HLD is engaged.

    If you switch on the AP at 400' AGL, the AFDS change to the default mode: N1, LVL CHG, HDG SEL. And automatically terminate the Takeoff mode. in your FMA you can see: N1|HDG SEL|MCP SPD.

    Tha's the real things. So it's correct that PM if you engage the AP above 400AGL terminate the Toff mode and set N1 (climb thrust). You see that on ED on Eicas.

    I don't have the PM but use PMDG that is really close about AFDS to the real one.

    If I can permit, I suggest you to download the AOM of B737 in the download section and studies the Automatic flight chapter on the OM Vol.2

    Hi arnaldo.
    I think you missunderstood what I said. I was describing what is happening with PM Auto pilot at the moment, not the real acft. What you described is the right one, and I know all this, Iīm a B737ngs flight instructor .
    best regards

    Re: What is "Autopilot Beta" ?

    From PM website:

    The current MCP/FCU builds include a beta autopilot which should work with
    FS2004, FSX and XPlane.
    When that option is unchecked, the normal FS autopilot is used.
    The intended benefit from this new method is to have more control over banking
    as well as a cleaner altitude capture and V/S control. In addition to this,
    at some later stage, it will give us a vastly improved Flight Director
    behaviour as well as improved roll and pitch modes, CWS etc. ...

    Sorry Leilson

    but you said that "PM when engage the AP, the AFDS switch to N1". Well, As you know that is the real mode.... If you ,as you know, engage the AP the AFDS terminate the TO mode and switch to Climb Mode automatically. That is not correct?
    Is not normal , as you say, that when you deselect N1 the AP disengage. Is that the item?
    Perhaps ww say the same thing.

    Regards
    Arnaldo

    Hi

    I'm just wondering what you are really because some days befor you wrote?

When I talk about the real acft, I must say that I know a lot of it, because Iīve been participating of many trainning sessions of some airline 737ng pilots. So, I can say that unfornatelly there is a lot to be fixed or implemented as you prefer. No, I donīt have a PM software , but I have some friends that have, and Iīve been following their drama , thatīs the reason of my posts in mycockpit , they donīt speak english and canīt complain .
